The terminal device 3 includes a terminal storage unit 31, a terminal reception unit 32, a terminal processing unit 33, a terminal transmission unit 34, a terminal reception unit 35, and a terminal output unit 36.

The storage unit 11 constituting the exchange management device 1 stores various types of information. The various types of information are, for example, user information (described later), business card information (described later), domain information (described later), exchange information, exchange relationship information, and various types of screen information. The various types of screen information are, for example, inquiry screen information for constructing an inquiry screen, and exchange relationship screen information for constructing a screen including one or more pieces of exchange relationship information. The screen information is realized, for example, by HTML, XML, or a program, but the means of realization, structure, etc. are not important.

The interaction information is information about interactions between two or more users. The interaction information is the source information for acquiring the interaction relationship information described below. The interaction information is, for example, email, calendar schedule information which is schedule information input to a calendar server, web conference schedule information which is schedule information input to a web conference server, etc. Email is electronic mail. The interaction information may be considered to include or not include information regarding the exchange of business cards. The calendar server may be referred to as a schedule management server, etc. The web conference server may be referred to as a web conference information management server, etc.

The calendar schedule information includes, for example, one or more of the following information: the name of the person attending the meeting, the name of the company of the person attending the meeting, the start time of the meeting, the end time of the meeting, the location of the meeting, etc.

The web conference schedule information includes, for example, one or more of the following information: the name of the other party in the conference, the name of the other party's company, the start time of the web conference, the end time of the web conference, etc.

Note that calendar schedule information and web conference schedule information may be referred to as schedule information without making a distinction between them.

The exchange relationship information is information indicating that an exchange has occurred or is occurring between two or more users. The exchange relationship information may be any information that can identify an exchange relationship. The exchange relationship information is usually information that associates other user information with a user identifier. The exchange relationship information may be information that has other user information and a user identifier, or the exchange relationship information may be information of a link between other user information and a user identifier, or other user information associated with a user identifier. The exchange relationship information may be information indicating that an exchange has occurred or is occurring between two or more users, and the data structure and content are not important. The user identifier is information that identifies a user. The user identifier is, for example, a user ID, an email address, a telephone number, a terminal identifier of a terminal device 3 used by a user, or the like, but may be any information that can identify a user. The identifier of the terminal device 3 is, for example, an IP address or a MAC address. The other user information is information regarding other users. Other users are users other than the user identified by the user identifier to which the other user information is associated. The other user information is, for example, the user identifier of the other user, and one or more of the user attribute values of the other user. The user attribute values are, for example, the name, the organization identifier of the organization to which the user belongs, the job title, the telephone number, the fax number, the address, and the URL. The organization identifier is, for example, the company name or the name of the organization. The address is, for example, the address of the organization to which the user belongs, or the home address. The URL is the URL of the homepage of the organization to which the user belongs.

The user information storage unit 111 stores one or more pieces of user information. The user information is information about a user. The user information has a user identifier that identifies the user. The user information may be associated with the user identifier. The user information has one or more user attribute values. It is preferable that the user information in the user information storage unit 111 is accurate information. It is even more preferable that the user information in the user information storage unit 111 is guaranteed to be accurate information. The user information in the user information storage unit 111 is, for example, information input by each user. The user information in the user information storage unit 111 is, for example, information input by a person after viewing the business card image of each user.

The business card information storage unit 112 stores one or more pieces of business card information. The business card information is information related to the business card. The business card information is associated with a user identifier. It is preferable that the user identifier corresponding to the business card information of a user and the user identifier included in the user information of the user are the same information, but they may be different information. However, it is preferable that the business card information of a user and the user information of the user are associated with each other. The business card information is also information related to the user's business card. The business card information has, for example, a business card image and one or more pieces of item information. The item information is information that constitutes the business card. The item information is, for example, a name, an organization identifier of the organization to which the user belongs, a job title, a telephone number, a fax number, an address, and a URL. The item information may be the same as a user attribute value.

The user information in the user information storage unit 111 and the business card information in the business card information storage unit 112 for a given user may be partially or entirely the same information.

The domain information storage unit 113 stores one or more pieces of domain information. The domain information is information that indicates the correspondence between the domain character string of an email address (domain name) and an organization identifier. The domain information is, for example, a pair of the domain character string of an email address and an organization identifier. The domain information is, for example, information that indicates the link between the domain character string of an email address and an organization identifier.

The exchange relationship storage unit 114 stores one or more pieces of exchange relationship information. The exchange relationship information usually corresponds to a user identifier. Corresponding to a user identifier may also mean including the user identifier. The exchange relationship information in the exchange relationship storage unit 114 is information that specifies the exchange between the user identified by the user identifier and other users. The exchange relationship information may have a type identifier. The type identifier is information that identifies the type of exchange. The type identifier is, for example, a flag that identifies the type of exchange, such as "email," "calendar," "web conference," and "business card." "Email" is information indicating that an exchange has occurred by email. "Calendar" is information indicating that an exchange has occurred corresponding to the schedule information registered in the calendar server. "Web conference" is information indicating that an exchange has occurred by web conference. "Business card" is information indicating that an exchange has occurred corresponding to receiving a business card.

The receiving unit 12 receives various types of information. The various types of information are, for example, a start instruction, exchange information, business card information, a user identifier, and an instruction to send various types of information. The start instruction is an instruction to start a process of acquiring one or more pieces of exchange information from one or more information servers 2. The instructions to send various types of information are, for example, an instruction to send user information, an instruction to send business card information, and an instruction to send exchange relationship information.

The business card information receiving unit 121 receives business card information related to the business card of another user in association with a user identifier. The user identifier here is the identifier of the user who received the business card corresponding to the business card information. The user identifier here is the identifier of a user who is not another user.

Here, acceptance usually means receiving information from the terminal device 3, but it also includes the concept of accepting information input from input devices such as a keyboard, mouse, or touch panel, and accepting information read from recording media such as optical disks, magnetic disks, and semiconductor memories.

The processing unit 13 performs various types of processing. The various types of processing are, for example, processing performed by the user identifier acquisition unit 131, the exchange information determination unit 132, the question unit 133, the other user information acquisition unit 134, the exchange relationship accumulation unit 135, the change determination unit 136, and the exchange processing unit 137.

The processing unit 13 acquires various pieces of information in accordance with an instruction to transmit various pieces of information. For example, the processing unit 13 acquires exchange relationship information from the exchange relationship storage unit 114 in accordance with an instruction to transmit exchange relationship information.

The user identifier acquisition unit 131 acquires one or more user identifiers. The user identifier acquisition unit 131 acquires the user identifier of the user for which exchange relationship information is to be acquired. The user identifier acquisition unit 131 acquires, for example, one or more user identifiers stored in the user information storage unit 111. The user identifier acquisition unit 131 acquires, for example, a user identifier transmitted from the terminal device 3 and received by the receiving unit 12. Note that the user identifier acquisition unit 131 may acquire one or more user identifiers from one or more information servers 2, a recording medium (not shown), an external device (not shown), etc.

The exchange information determination unit 132 determines, from among one or more pieces of exchange information, exchange information that corresponds to the user identifier acquired by the user identifier acquisition unit 131 and satisfies a predetermined condition. The one or more pieces of exchange information are information acquired directly or indirectly from the information server 2. The one or more pieces of exchange information are, for example, one or more pieces of exchange information received by the receiving unit 12, one or more pieces of exchange information stored in the storage unit 11, one or more pieces of exchange information stored in each of the one or more information servers 2, and one or more pieces of exchange information stored in an information processing device (not shown) acquired from each of the one or more information servers 2. It is preferable that the exchange information is information that was originally stored in the information server 2. The exchange information is, for example, email or schedule information. The exchange information may be information that has been processed from information originally stored in the information server 2.

Determining the exchange information may, for example, involve obtaining the exchange information, obtaining a link to the exchange information, etc.

The predetermined conditions are, for example, business exchange conditions. Business exchange conditions are conditions that specify that the exchange is in the context of business.

The predetermined condition is, for example, that user information corresponding to the information obtained from the exchange information (e.g., name, company name, etc.) exists in the user information storage unit 111.

The exchange information determination unit 132 determines exchange information that corresponds to the user identifier acquired by the user identifier acquisition unit 131, for example, and that satisfies the business exchange conditions.

The interaction information determination unit 132 determines emails that satisfy predetermined conditions from one or more emails sent to an email address corresponding to the user identifier acquired by the user identifier acquisition unit 131. The predetermined conditions here are appropriately referred to as email conditions.

The interaction information determination unit 132 uses the sender email address of one or more stored emails to determine which emails satisfy the email conditions.

Email conditions include, for example, conditions regarding responses by email, conditions regarding email addresses, and conditions regarding the content of emails.

A condition for responding by email is, for example, that emails are being sent and replied to between two users. This condition is set so that a one-way email transmission alone is not considered to be an exchange.

A condition for responding by email is, for example, that there is N or more exchanges (N is a natural number equal to or greater than 2) between two users. Such a condition is intended to ensure that, for example, small exchanges or one-sided email transmissions are not considered to be exchanges under the present application.

The condition for responding by email is, for example, that two users exchange emails N or more times over a certain period of time (e.g., three months or one year). This condition is used to exclude short-term email exchanges from being considered as exchanges of the present application.

The condition for email addresses is that the recipient's (e.g., the sender of the email, the recipient of the email) email address contains a specified character string (e.g., "co.jp", "ac.jp", etc.). The condition for email addresses is that the recipient's email address does not contain a specified character string. The condition for email addresses is, for example, that the recipient's email address is not an email address that is considered to be a personal email address (e.g., an address that contains "gmail.com" or "yahoo.co.jp").

The condition regarding the content of the email is, for example, that it is not spam. Note that the technology for determining whether or not it is spam can be a known mailer technology. Also, the condition regarding the content of the email is, for example, that it is an email that contains many terms stored in a business terminology dictionary (not shown). An email that contains many terms means that it contains a number of terms equal to or greater than a threshold value, or contains terms at a ratio equal to or greater than a threshold value. Also, the condition regarding the content of the email is, for example, that it is determined to be a business email as a result of a classification process (which may be called a prediction process) using a machine learning classifier (which may be called a learning model, a learning device, etc.). Note that such a classifier is data obtained by performing a learning process using a machine learning algorithm using one or more positive examples that are business emails and one or more negative examples that are not business emails as teacher data. Note that the so-called deep learning, random forest, decision tree, SVM, etc. can be used for machine learning, but the algorithm is not important. Also, for machine learning, for example, various modules of TensorFlow, a random forest module of R language, TinySVM, etc. can be used. A business term dictionary is a storage area such as a database or file that stores two or more terms used in business. A business term may be a phrase or sentence. Examples of phrases or sentences include "Thank you for your continued support," "We look forward to working with you in the future," and "King Regards."

The exchange information determination unit 132 determines schedule information that satisfies a predetermined condition from one or more pieces of schedule information corresponding to the user identifier acquired by the user identifier acquisition unit 131. Such a predetermined condition is appropriately referred to as a schedule condition.

The schedule condition is, for example, schedule information for a schedule on a work day (for example, Monday to Friday). The schedule condition is, for example, schedule information for a schedule on a work day during work hours (for example, between 9:00 and 18:00). The schedule condition is, for example, schedule information including an organization identifier such as a company name. The schedule information including an organization identifier includes a predetermined character string indicating that the information is a company, such as "Inc.", "Limited Company," or "(Stock)." Machine learning can be used to identify whether a character string is an organization identifier. That is, the exchange information determination unit 132 may provide a classifier that classifies whether or not the character string is an organization identifier and a character string obtained from the schedule information to a module that performs machine learning prediction processing, and obtain a classification result (whether or not the character string is an organization identifier). The classifier provides one or more positive examples that are organization identifiers and one or more negative examples that are not organization identifiers to a module that performs machine learning learning processing, and obtains the data. As described above, deep learning, random forest, decision tree, SVM, etc. can be used for such machine learning, but the algorithm is not important.

The predetermined condition may also be, for example, that the response to a query by the questioning unit 133 (described later) is a response to the effect that "exchange relationship information will be accumulated."

The questioning unit 133 queries the user as to whether or not to store exchange relationship information. Querying the user means, for example, sending the query to the user's terminal device 3, but it does not have to be a proactive query, and the query method does not matter. Furthermore, the timing or trigger of such a query to the user does not matter.

For example, when the user's terminal device 3 accesses the exchange management device 1, the questioning unit 133 transmits screen information (question screen information) constituting a question screen for inquiring the user whether or not to store the exchange relationship information to the terminal device 3. The questioning screen is, for example, a screen including an interface such as a button or menu item that instructs the user to store the exchange relationship information, or a screen including a message that inquires the user whether or not to store the exchange relationship information. For example, after logging in to the exchange management device 1, the questioning unit 133 transmits the question screen information to the terminal device 3. For example, when the exchange management device 1 receives an instruction to output a question screen from the terminal device 3, the questioning unit 133 transmits the question screen information to the terminal device 3. For example, each time the questioning unit 133 acquires exchange information, the questioning unit 133 inquires the user whether or not to store the exchange relationship information. For example, the questioning unit 133 inquires the user at a predetermined date and time (for example, "12 o'clock every day", "10 o'clock on the first day of each month", etc.). For example, the questioning unit 133 inquires the user when an instruction having a user identifier is received. This instruction is an instruction to store exchange relationship information.

The other user information acquisition unit 134 acquires other user information including the other user identifier. The other user identifier is a user identifier different from the user identifier acquired by the user identifier acquisition unit 131.

The other user information acquisition unit 134 acquires other user information, for example, by using interaction information. The other user information acquisition unit 134 acquires other user information, for example, by using information corresponding to the interaction information.

The other user information acquisition unit 134 searches the user information storage unit 111 using, for example, a character string included in the exchange information determined by the exchange information determination unit 132 or a user identifier corresponding to the exchange information, and acquires other user information using the search results. The other user information acquisition unit 134 searches the user information storage unit 111 using, for example, a character string (for example, a name and a company name) included in the exchange information determined by the exchange information determination unit 132 as a key, and acquires other user information including part or all of the information of the user information including the character string. The other user information acquisition unit 134 searches the user information storage unit 111 using, for example, a character string included in the exchange information determined by the exchange information determination unit 132 as a key, determines user information including a character string that matches or is similar to the character string, acquires a user identifier corresponding to the user information as the other user identifier, and acquires other user information including the other user identifier. Note that a similar character string is a character string with the highest similarity, or a character string with a similarity equal to or greater than a threshold value.

Below, the operation of the other user information acquisition unit 134 will be described in the cases where the interaction information is email, where the interaction information is calendar schedule information, where the interaction information is web conference schedule information, and where the business card information receiving unit 121 receives business card information.
(1) When the information exchanged is via email

The other user information acquisition unit 134 acquires other user information, for example, using the email determined by the interaction information determination unit 132.

The other user information acquisition unit 134 acquires other user information, for example, by using the signature information in the email determined by the interaction information determination unit 132.

Note that the other user information here may also include email-related information about the email. The email-related information is, for example, one or more of the following information: the date and time the email was received, the body of the email, the title of the email, etc.

The other user information acquisition unit 134, for example, detects a signature character string from the email determined by the interaction information determination unit 132, and acquires one or more user attribute values from the signature character string. The user attribute value has, for example, one or more pieces of information among name, company name, department name, title, address, telephone number, fax number, email address, and URL. The other user information acquisition unit 134 then acquires other user information having, for example, the one or more user attribute values.

The other user information acquisition unit 134, for example, detects a signature character string from the email determined by the interaction information determination unit 132 (here, typically a received email), acquires one or more user attribute values from the signature character string, searches the user information storage unit 111 using the one or more user attribute values, and acquires other user information that contains some or all of the matching user information.

The method by which the other user information acquisition unit 134 detects the signature character string from the email is not important. For example, the other user information acquisition unit 134 checks the lines above the lowest line containing characters in the email, detects a blank line without characters, and acquires the line next to the blank line to the lowest line containing characters as the character string in the signature area. For example, the other user information acquisition unit 134 checks from the first line of the email, and acquires the line next to the signature delimiter line (e.g., a line containing a predetermined number or more consecutive characters "*", "━", or "+", etc.)) that is a line containing a predetermined character string, to the line one line above the signature delimiter line that is a lower line of the line, as the character string in the signature area. For example, the other user information acquisition unit 134 acquires the character string of a predetermined number of lines immediately below a line containing a specific character string in the email (e.g., a line containing "Best Regards", "Thank you in advance", etc.) as the character string in the signature area.

The other user information acquisition unit 134 acquires the domain name of the email address of the sender of the email (here, the received email) determined by the exchange information determination unit 132, acquires the organization identifier corresponding to the domain name from the domain information storage unit 113, which stores one or more pieces of domain information each having a pair of a domain name and an organization identifier, and acquires other user information using the organization identifier.

The other user information acquisition unit 134 searches the user information storage unit 111 using, for example, the organization identifier and the name in the email, and acquires other user information that has one or more user attribute values that match the user information.

The other user information acquisition unit 134 acquires the email address of the sender of the email (here, the received email) determined by the interaction information determination unit 132, searches the user information storage unit 111 using the email address, and acquires other user information that contains some or all of the matching user information. Note that the user information here typically includes one or more accurate attribute values of the user.

The other user information acquisition unit 134 acquires the name or other character string preceding the specified character string "sama," "san," or "dono" in the email determined by the exchange information determination unit 132, searches the user information storage unit 111 using the name or other character string, and acquires other user information that contains some or all of the matching user information.

The other user information acquisition unit 134 acquires a character string including the first character of the email (here, a sent email) determined by the interaction information determination unit 132 as a name, etc., searches the user information storage unit 111 using the name, etc., and acquires other user information having some or all of the matching user information.
(2) When the exchange information is calendar schedule information

The other user information acquisition unit 134 acquires other user information using the calendar schedule information determined by the interaction information determination unit 132. The other user information here may include some or all of the calendar schedule information. Some or all of the calendar schedule information may be, for example, the start date and time of the meeting, the location of the meeting, information identifying that it is a face-to-face meeting, etc.

The other user information acquisition unit 134, for example, acquires one or more attribute values (e.g., company name, name, etc.) from the calendar schedule information determined by the interaction information determination unit 132, searches the user information storage unit 111 using the one or more attribute values, and acquires other user information having some or all of the matching user information.
(3) When the information about the exchange is information about a scheduled web conference

The other user information acquisition unit 134 acquires other user information using the web conference schedule information determined by the exchange information determination unit 132. The other user information here may include some or all of the information on the web conference schedule information. Some or all of the information on the web conference schedule information is, for example, the start date and time of the conference, information identifying it as a web conference, etc.

The other user information acquisition unit 134, for example, acquires one or more attribute values (e.g., company name, name, etc.) from the web conference schedule information determined by the exchange information determination unit 132, searches the user information storage unit 111 using the one or more attribute values, and acquires other user information having some or all of the matching user information.
(4) When the business card information receiving unit 121 receives business card information

The other user information acquisition unit 134 may acquire other user information including other user identifiers corresponding to the business card information accepted by the business card information acceptance unit 121.

The other user information acquisition unit 134 searches the user information storage unit 111 using, for example, one or more items of information contained in the business card information, and acquires other user information that contains some or all of the matching user information.

The other user information acquisition unit 134 acquires other user information including, for example, one or more items of information contained in the business card information accepted by the business card information acceptance unit 121.

The exchange relationship storage unit 135 stores exchange relationship information that associates other user information with a user identifier. The other user information here is information acquired by the other user information acquisition unit 134. The user identifier here is information acquired by the user identifier acquisition unit 131.

The exchange relationship storage unit 135 stores exchange relationship information, which is other user information acquired by the other user information acquisition unit 134, in association with the user identifier acquired by the user identifier acquisition unit 131, for example.

The exchange relationship storage unit 135 stores exchange relationship information having, for example, the user identifier acquired by the user identifier acquisition unit 131 and other user information acquired by the other user information acquisition unit 134.

The exchange relationship storage unit 135 stores exchange relationship information, which is link information to other user information acquired by the other user information acquisition unit 134, for example, in association with the user identifier acquired by the user identifier acquisition unit 131.

There is no restriction on where the exchange relationship accumulation unit 135 accumulates the exchange relationship information. For example, the exchange relationship accumulation unit 135 accumulates the exchange relationship information in the exchange relationship storage unit 114. However, the exchange relationship accumulation unit 135 may accumulate the exchange relationship information in another device not shown. It is preferable that the exchange relationship accumulation unit 135 accumulates the exchange relationship information in a device that uses the exchange relationship information.

The exchange relationship storage unit 135 stores the exchange relationship information only when, for example, the result of the inquiry by the questioning unit 133 is that the exchange relationship information should be stored. In other words, it is preferable to store only the exchange relationship information that the user determines that he or she wants to store.

The change determination unit 136 determines whether there is a change in the information of other users corresponding to the interaction information or business card information. Changes include, for example, transfers within an organization, promotions, job changes, employment, etc.

The change determination unit 136, for example, determines the user information that is most similar to the other user information acquired by the other user information acquisition unit 134 from the user information in the user information storage unit 111, determines whether one or more predetermined user attribute values, such as an organization identifier, department identifier, job title, and address, included in the other user information are different from the corresponding user attribute values of the user information, and determines that a change has occurred if different user attribute values exist.

The change determination unit 136 searches the user information storage unit 111 using the other user information acquired by the other user information acquisition unit 134, which includes a name and one or more other user attribute values (e.g., company name, title, department name), and determines whether or not there is user information with a matching name and one or more other user attribute values that are different. If the user information is found, it determines that there has been a change in the user corresponding to the user information.

The AC processing unit 137 performs a predetermined process when the change determination unit 136 determines that a change has occurred.

When the change determination unit 136 determines that there is a change, it is preferable that the exchange processing unit 137 performs a predetermined process using the exchange relationship information stored by the exchange relationship storage unit 135 in association with the user identifier.

The predetermined processing includes notification of transfer information, posting of transfer information on a web page, etc. Transfer information is information indicating that a user has been transferred, that there has been a change in the user, etc. It is preferable that the transfer information includes one or more user attribute values after the change. However, the transfer information may be, for example, only the name and information indicating that a change has occurred. Notification of transfer information is processing to inform other users of transfer information.

When notifying the change information, the communication processing unit 137 acquires the user identifier of the user for whom the change determination unit 136 has determined that there has been a change, and transmits the change information from one or more pieces of communication relationship information corresponding to the user identifier to other users identified by the other user identifier corresponding to the user identifier. The means for transmitting the change information may be any means, such as email, fax, or short message. The transmission of the change information may be a process for displaying the change information on a screen output by other users when the other users identified by the other user identifiers log in to the communication management device 1.

The communication processing unit 137 posts change information on the web page indicating that a user who has changed has been transferred, that there has been a change in the user, etc.

The transmitting unit 14 transmits various types of information. For example, the various types of information are information indicating that exchange relationship information has been accumulated. The transmitting unit 14 transmits various types of information to the terminal device 3, for example.

The transmitting unit 14 transmits, for example, various types of information corresponding to an instruction to transmit various types of information. The transmitting unit 14 transmits, for example, one or more pieces of exchange relationship information corresponding to an instruction to transmit exchange relationship information.

Various types of information are stored in the server storage unit 21 that constitutes the information server 2.

When the information server 2 is a mail server, the server storage unit 21 stores one or more emails. For example, an email is associated with a recipient email address that receives the email. For example, an email is associated with a sender email address that sent the email. For example, an email is associated with a user identifier.

When the information server 2 is a calendar server, the server storage unit 21 stores one or more calendar schedule information. The calendar schedule information is associated with a user identifier. Note that the user identifier of a user's calendar server and the user identifier used by the exchange management device 1 of a user may be different. However, when the two user identifiers are different, the storage unit 11 manages the correspondence between the two user identifiers.

When the information server 2 is a web conference server, the server storage unit 21 stores one or more pieces of web conference schedule information. The web conference schedule information is associated with a user identifier. Note that the user identifier of a user's web conference server and the user identifier used by a user's exchange management device 1 may be different. However, when the two user identifiers are different, the storage unit 11 is assumed to manage the correspondence between the two user identifiers.

The server receiving unit 22 receives various instructions and information. The server receiving unit 22 receives various instructions and information, for example, from the exchange management device 1 or the terminal device 3. The various instructions and information are, for example, an instruction to send exchange information, and exchange information (e.g., email, schedule information). An instruction to send exchange information is an instruction to send exchange information.

The server processing unit 23 performs various processes. For example, various processes are processes for storing received exchange information in the server storage unit 21. For example, various processes are processes for acquiring exchange information corresponding to an instruction to transmit exchange information from the server storage unit 21.

The server transmission unit 24 transmits various types of information. The various types of information are exchange information.

The terminal storage unit 31 constituting the terminal device 3 stores various types of information. The various types of information include, for example, a user identifier, business card information, exchange information, and exchange-related information.

The terminal reception unit 32 receives various instructions and information. Examples of the instructions and information include a start instruction and business card information.

Here, acceptance is a concept that includes the acceptance of information input from input devices such as a keyboard, mouse, or touch panel, the reception of information transmitted via a wired or wireless communication line, and the acceptance of information read from a recording medium such as an optical disk, magnetic disk, or semiconductor memory. The means for inputting various instructions and information can be anything, such as a touch panel, keyboard, mouse, or menu screen.

The device processing unit 33 performs various types of processing. For example, various types of processing are processing to convert instructions and information accepted by the device accepting unit 32 into instructions and information with a data structure to be transmitted. For example, various types of processing are processing to convert information received by the device receiving unit 35 into information with a data structure to be output.

The terminal transmission unit 34 transmits various instructions and information. Examples of the instructions and information include a start instruction and business card information.

The terminal receiving unit 35 receives various types of information. The various types of information include, for example, various types of screen information, exchange relationship information, business card information, and transfer information.

The terminal output unit 36 outputs various types of information. Examples of the various types of information include various types of screen information, exchange relationship information, business card information, and transfer information.

Here, output is a concept that includes displaying on a display, projecting using a projector, printing on a printer, outputting sound, sending to an external device, storing on a recording medium, and passing on the processing results to other processing devices or other programs, etc.

The storage unit 11, the user information storage unit 111, the business card information storage unit 112, the domain information storage unit 113, the server storage unit 21, and the terminal storage unit 31 are preferably non-volatile recording media, but can also be realized using volatile recording media.

The process by which information is stored in the storage unit 11, etc. is not important. For example, information may be stored in the storage unit 11, etc. via a recording medium, information transmitted via a communication line, etc. may be stored in the storage unit 11, etc., or information inputted via an input device may be stored in the storage unit 11, etc.

The receiving unit 12, business card information receiving unit 121, server receiving unit 22, and terminal receiving unit 35 are typically implemented using wireless or wired communication means, but may also be implemented using means for receiving broadcasts.

The processing unit 13, user identifier acquisition unit 131, exchange information determination unit 132, question unit 133, other user information acquisition unit 134, exchange relationship storage unit 135, change determination unit 136, exchange processing unit 137, server processing unit 23, and device processing unit 33 can usually be realized by a processor, memory, etc. The processing procedure of the processing unit 13 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may also be realized by hardware (dedicated circuit). The processor may be, for example, an MPU, CPU, GPU, etc., and the type is not important.

The transmitting unit 14, the questioning unit 133, the server transmitting unit 24, and the terminal transmitting unit 34 are typically implemented using wireless or wired communication means, but may also be implemented using broadcasting means.

The terminal reception unit 32 can be realized by a device driver for an input means such as a touch panel or keyboard, or control software for a menu screen, etc.

The terminal output unit 36 may or may not include an output device such as a display or speaker. The terminal output unit 36 may be realized by driver software for an output device, or by a combination of driver software for an output device and an output device, etc.

Next, an example of the operation of the AC management system A will be described. First, an example of the operation of the AC management device 1 will be described using the flowchart in FIG. 4.

(Step S401) The processing unit 13 judges whether it is time to acquire exchange information. If it is time to acquire exchange information, the process proceeds to step S402, and if it is not time to acquire exchange information, the process proceeds to step S409.

(Step S402) The processing unit 13 assigns 1 to counter i.

(Step S403) The processing unit 13 judges whether or not the i-th type of exchange information for which exchange information is to be acquired exists. If the i-th type of exchange information exists, the process proceeds to step S404, and if the i-th type of exchange information does not exist, the process returns to step S401. Note that it is assumed that which type of exchange information exists is predetermined and that the processing unit 13 is capable of judging whether or not it exists. Also, for example, of the three types of exchange information, namely, email, schedule information on a calendar server, and schedule information on a web conference server, one or more types of exchange information exist.

(Step S404) The processing unit 13 assigns 1 to counter j.

(Step S405) The processing unit 13 determines whether or not the user identifier of the jth user for which exchange relationship information processing is to be performed exists. If the user identifier of the jth user exists, the process proceeds to step S406, and if not, the process proceeds to step S408. Note that exchange relationship information processing is a process of acquiring exchange relationship information for a user and storing it, etc. Also, the processing unit 13 determines, for example, whether or not the user identifier of the jth user exists in the user information storage unit 111.

(Step S406) The processing unit 13 performs exchange relationship information processing. An example of exchange relationship information processing is described using the flowchart in FIG. 5.

(Step S407) The processing unit 13 increments the counter j by 1. Return to step S405.

(Step S408) The processing unit 13 increments the counter i by 1. Return to step S403.

(Step S409) The business card information receiving unit 121 determines whether or not business card information has been received. If business card information has been received, the process proceeds to step S410; if business card information has not been received, the process proceeds to step S411.

(Step S410) The processing unit 13 performs business card information processing. Return to step S401. An example of business card information processing will be described using the flowchart in FIG. 7.

(Step S411) The receiving unit 12 determines whether or not the exchange information has been received. If the exchange information has been received, the process proceeds to step S412. If the exchange information has not been received, the process returns to step S401.

(Step S412) The processing unit 13 performs exchange relationship information processing. Return to step S401. An example of exchange relationship information processing will be described with reference to the flowchart in FIG. 5.

In the flowchart of FIG. 4, the process of acquiring exchange relationship information for each user is performed for each information server 2 in order. However, the process of acquiring exchange relationship information from one or more information servers 2 for each user may be performed. In other words, the order of the processes in the flowchart of FIG. 4 does not matter.

In the flowchart of FIG. 4, exchange relationship information or exchange information that can be the source of exchange relationship information may be acquired in advance for each user and recorded in the storage unit 11 or a device not shown, and at a predetermined timing, the user may be asked whether or not to store the exchange relationship information. If the answer to the question is yes, the exchange relationship information may be stored. The predetermined timing may be, for example, the timing when the user logs in to the exchange management device 1 or the timing when an instruction from the user is received, but the timing is not important.

Furthermore, in the flowchart of Figure 4, processing ends when the power is turned off or an interrupt occurs to end processing.

Next, an example of the exchange relationship information processing in steps S406 and S412 will be described using the flowchart in FIG. 5.

(Step S501) The exchange information determination unit 132 acquires one or more pieces of exchange information corresponding to the user identifier from the information server 2 in which the i-th type of exchange information exists in step S403, or acquires the exchange information received in step S411.

When the exchange information determination unit 132 acquires one or more pieces of exchange information corresponding to a user identifier from the information server 2, the user identifier acquisition unit 131 acquires the user identifier. Here, the user identifier acquired by the user identifier acquisition unit 131 is the j-th user identifier in step S405.

(Step S502) The AC information determination unit 132 assigns 1 to counter i.

(Step S503) The exchange information determination unit 132 determines whether or not the i-th exchange information exists among the one or more pieces of exchange information acquired in step S501. If the i-th exchange information exists, the process proceeds to step S504, and if the i-th exchange information does not exist, the process returns to the upper process.

(Step S504) The AC information determination unit 132 determines whether the i-th AC information satisfies a predetermined condition. If the i-th AC information satisfies the predetermined condition, the process proceeds to step S505. If the i-th AC information does not satisfy the predetermined condition, the process proceeds to step S514.

(Step S505) The other user information acquisition unit 134 acquires other user information using the i-th interaction information.

(Step S506) The questioning unit 133 judges whether or not to make an inquiry to the user. If an inquiry is to be made, the process proceeds to step S506, and if an inquiry is not to be made, the process proceeds to step S510. Note that, for example, whether or not to make an inquiry is determined in advance. Also, the questioning unit 133 judges whether or not to make an inquiry depending on the other user information. For example, the questioning unit 133 judges whether exchange relationship information corresponding to the other user information acquired in step S505 has already been stored, and if it has not already been stored, judges to make an inquiry.

(Step S507) The questioning unit 133 asks the user whether or not to store exchange relationship information corresponding to the other user information acquired in step S505.

(Step S508) The interrogation unit 133 determines whether or not a response to the inquiry result in step S507 has been received from the terminal device 3. If a response has been received, the process proceeds to step S509; if not, the process returns to step S508.

(Step S509) If the response received in step S508 is a response indicating that exchange relationship information will be stored, the exchange relationship storage unit 135 proceeds to step S510, and if the response is a response indicating that exchange relationship information will not be stored, the exchange relationship storage unit 135 proceeds to step S512.

(Step S510) The exchange relationship storage unit 135 acquires exchange relationship information using the other user information acquired in step S505 and the user identifier corresponding to the exchange information.

(Step S511) The exchange relationship storage unit 135 stores the exchange relationship information acquired in step S510.

(Step S512) The change determination unit 136 compares the other user information acquired in step S505 with the corresponding user information to determine whether it has been changed (whether there has been a change in the user, etc.). If it has been changed, the process proceeds to step S513; if it has not been changed, the process proceeds to step S514.

(Step S513) The communication processing unit 137 performs communication processing. An example of communication processing is described using the flowchart in FIG. 6.

(Step S514) The AC information determination unit 132 increments the counter i by 1. Return to step S503.

Next, an example of the exchange process in step S513 will be described using the flowchart in FIG. 6.

(Step S601) The AC processing unit 137 assigns 1 to counter i.

(Step S602) The communication processing unit 137 judges whether or not another i-th user identifier exists. If the i-th user identifier exists, the process proceeds to step S603, and if the i-th user identifier does not exist, the process returns to the upper level process. The communication processing unit 137 judges, for example, whether or not another i-th user identifier exists in the user information storage unit 111. The communication processing unit 137 also judges, for example, whether or not another i-th user identifier exists in the communication relationship storage unit 114.

(Step S603) The interaction processing unit 137 determines whether the i-th user identifier exists in the interaction relationship information in the interaction relationship storage unit 114 corresponding to the user identifier of the relevant user (whether there is an interaction with a user identified by another i-th user identifier). If there is an interaction, the process proceeds to step S604, and if there is no interaction, the process proceeds to step S605.

(Step S604) The interaction processing unit 137 transmits the acquired other user information to the other user identified by the i-th user identifier.

(Step S605) The AC processing unit 137 increments the counter i by 1. Return to step S602.

In the flowchart of FIG. 6, for example, in step S602, the exchange processing unit 137 may obtain a user identifier corresponding to the other user information determined to have been changed in step S512, and determine whether or not the i-th other user information paired with the user identifier exists in the exchange relationship storage unit 114. Then, if the i-th other user information exists in the exchange relationship storage unit 114, the process may proceed to step S604. In this case, step S603 is not necessary.

In other words, in the flowchart of Figure 6, it is sufficient to be able to notify other users who have contact with the user who has been transferred of the transfer information.

Next, an example of business card information processing in step S410 will be described using the flowchart in Figure 7.

(Step S701) The other user information acquisition unit 134 acquires the received business card information. Next, the other user information acquisition unit 134 uses the business card information to acquire other user information including other user identifiers.

(Step S702) The exchange relationship storage unit 135 acquires exchange relationship information that associates the other user information acquired in step S701 with the user identifier.

(Step S703) The exchange relationship storage unit 135 stores the exchange relationship information acquired in step S702.

(Step S704) The change determination unit 136 compares the other user information acquired in step S701 with the corresponding user information to determine whether it has been changed (whether there has been a transfer, etc.). If it has been changed, the process proceeds to step S705, and if it has not been changed, the process returns to the upper level process.

(Step S705) The AC processing unit 137 performs AC processing. It returns to the upper level processing. An example of the AC processing was explained using the flowchart in Figure 6.

In the flowchart of FIG. 7, the processing unit 13 may use the received business card information to construct business card information to be stored, and may store the business card information in the business card information storage unit 112.

Next, an example of the operation of the information server 2 will be described. When the server receiving unit 22 of the information server 2 receives exchange information, the server processing unit 23 stores the exchange information in the server storage unit 21. In addition, when the server receiving unit 22 receives an instruction to transmit exchange information from the terminal device 3 or the exchange management device 1, it transmits the exchange information corresponding to the transmission instruction to the terminal device 3 or the exchange management device 1.

Next, an example of the operation of the terminal device 3 will be described. The terminal reception unit 32 of the terminal device 3 receives various instructions and information. The terminal processing unit 33 converts the instructions and information received by the terminal reception unit 32 into instructions and information with a data structure to be transmitted. The terminal transmission unit 34 transmits the various instructions and information to the exchange management device 1 and the information server 2. In response to the transmission of various instructions and information to the exchange management device 1, the terminal reception unit 35 receives various screen information, exchange relationship information, business card information, transfer information, etc. The terminal processing unit 33 converts the information received by the terminal reception unit 35 into information with a data structure to be output. The terminal output unit 36 outputs various screen information, exchange relationship information, business card information, transfer information, etc.

The specific operation of the AC management system A in this embodiment will be described below.
The conceptual diagram of the exchange management system A is shown in FIG.

Now, assume that the user information storage unit 111 of the interaction management device 1 stores a user information management table having the structure shown in FIG. 8. The user information management table is a table for managing user information. In this specific example, the user information management table also serves as a business card information management table. In other words, in the user information management table, information having a business card image (e.g., information "ID=1, 2, 3") is business card information, and each user attribute value of the user information in the business card information is item information. Note that information without a business card image (e.g., information "ID=384") may also be considered to be business card information.
Furthermore, a business card information management table may be stored in the business card information storage unit 112 separately from the user information management table.

The user information management table manages one or more records that have an "ID," "user identifier," "password," "user information," and "business card image." The "user information" has information such as "name," "notification information (email address)," and "company name." Note that the "ID" is information that identifies the record, and although not shown in Figure 8, it is preferable for the "user information" to have user attribute values such as a department identifier, title, telephone number, fax number, URL, etc.

The domain information storage unit 113 also stores a domain information management table shown in FIG. 9. The domain information management table manages one or more records that have an "ID," "domain information," and an "organization identifier."

In addition, the exchange relationship storage unit 114 stores an exchange relationship management table having a structure shown in FIG. 10. The exchange relationship management table is a table that stores one or more exchange relationship information. The exchange relationship management table manages one or more records having "ID", "user identifier", "other user identifier", "type identifier", and "additional information". The other user identifier that pairs with the user identifier is the identifier of the other user who has interacted with the user identified by the user identifier through some exchange means. The "type identifier" is information indicating the type of interaction. Here, the "type identifier" is one of "email (e.g., "1")", "calendar (e.g., "2")", "web conference (e.g., "3")", and "business card (e.g., "4")". The "additional information" is additional information in the exchange relationship information, such as e-mail-related information, business card exchange-related information, calendar-related information, and web conference-related information. Here, the business card exchange-related information has a registration date indicating the date on which the business card information was registered, but may also have other information such as a memo entered by the user. Calendar-related information here includes start date/time, end date/time, location, title, etc. Web conference-related information here includes start date/time, end date/time, topic, etc.

The storage unit 11 also stores a business terminology dictionary as shown in FIG. 11. The business terminology dictionary stores character strings such as terms, phrases, or sentences that are frequently used in business situations, business emails, and business-related schedule information.

The storage unit 11 also stores a non-business terminology dictionary as shown in FIG. 12. The non-business terminology dictionary stores character strings such as terms, phrases, or sentences that are not used or are rarely used in business situations, business emails, or business-related schedule information.

The storage unit 11 also stores a condition management table shown in FIG. 13. The condition management table is a table that manages business exchange conditions. The condition management table stores one or more records having an "ID," "business exchange conditions," and "type identifier."

Here, the business exchange condition for "ID=1" is that the recipient's email address contains either "co.jp" or "ac.jp", etc. The business exchange condition for "ID=2" is that there has been two or more email exchanges (one or more replies to an email sent). The business exchange condition for "ID=3" is that the number of business terms in the string of characters in the email is greater than the number of non-business terms. The business exchange condition for "ID=4" is that the calendar event information contains business terms. The business exchange condition for "ID=5" is that the calendar event information is for a day other than Saturdays, Sundays, and holidays (usually a working day), and the time period indicated by the event information is between 9:00 and 18:00.

In addition, if the type identifier is "email," the exchange information determination unit 132 determines that email that satisfies "ID=1" AND "ID=2" AND "ID=3" is the exchange information that will be the source for obtaining exchange relationship information.

In addition, in this case, if the type identifier is "calendar," the exchange information determination unit 132 determines that the calendar schedule information that satisfies "ID=4" OR "ID=5" is the exchange information that will be the source for obtaining exchange relationship information.

Furthermore, if the type identifier is "web conference", the exchange information determination unit 132 determines that the calendar schedule information that satisfies "ID=6" is the exchange information that will be the source for obtaining exchange relationship information.

The exchange management system A has, as information server 2, a mail server 2 (1) that manages emails of one or more users, a calendar server 2 (2) that manages calendar schedule information of one or more users, and a web conference server 2 (3) that manages web conference schedule information of one or more users.

The calendar schedule information management table shown in FIG. 14 is stored in the server storage unit 21 of the calendar server 2 (2). The calendar schedule information management table manages one or more records having an "ID," "user identifier," "start date and time," "end date and time," "title," etc.

The server storage unit 21 of the web conference server 2 (3) stores the web conference schedule information management table shown in FIG. 15. The web conference schedule information management table manages one or more records having an "ID," "user identifier," "start date and time," "end date and time," "topics," etc.

In this situation, the following three specific examples will be described. Specific Example 1 is a process in which interaction information is determined using email, calendar schedule information, and web conference schedule information, and other user information corresponding to the interaction information is stored. The stored other user information is information that can be the source of interaction relationship information. Specific Example 2 is a specific example that describes a process in which the stored other user information is used to inquire of the user whether or not to store the interaction relationship information, and the interaction relationship information is stored in response to the other user information that is stored. Specific Example 3 is an example in which interaction relationship information is stored when business card information of a person with whom business cards have been exchanged is received.

(Specific Example 1)
For example, it is assumed that a predetermined time has come and the processing unit 13 of the AC management device 1 has determined that it is time to obtain AC information.

Next, the processing unit 13 obtains the first user identifier "1001" from the user information management table.

Next, the exchange information determination unit 132 acquires one or more unprocessed emails corresponding to the user identifier "1001" from the mail server 2(1). It is assumed that the exchange information determination unit 132 has a means (API, IP address, etc.) for accessing the mail server 2(1). It is assumed that an unprocessed email is an email that the exchange information determination unit 132 has not yet read from the mail server 2(1). Here, it is assumed that the exchange information determination unit 132 acquires emails 1601, 1602, etc. shown in FIG. 16, which are addressed to the user identifier "1001", from the mail server.

Next, the exchange information determination unit 132 judges whether the emails (1601, 1602, etc.) in FIG. 16 satisfy all the business exchange conditions of "ID=1, 2, 3" in FIG. 13. Here, the exchange information determination unit 132 judges that the business exchange condition of "ID=1" is satisfied because the sender's email address of email 1601 in FIG. 16 is "ay@s.jp". In addition, the exchange information determination unit 132 detects from the read email (not shown) that Yamada Ichiro, identified by user identifier "1001", has responded to this email, and judges that the business exchange condition of "ID=2" is satisfied. Furthermore, the exchange information determination unit 132 performs morphological analysis on the character string paired with the <title> of email 1601 and the character string paired with the <body>, obtains one or more terms, and refers to the business term dictionary in FIG. 11 to obtain the number of business terms in email 1601. The exchange information determination unit 132 also refers to the non-business term dictionary in FIG. 12 and obtains the number of non-business terms in email 1601. The exchange information determination unit 132 then determines that email 1601 in FIG. 16 satisfies the business exchange condition for "ID=3." From the above, the exchange information determination unit 132 determines email 1601 in FIG. 16 as exchange information that satisfies the predetermined condition.

Next, the other user information acquisition unit 134 acquires other user information using the exchange information. Specifically, the other user information acquisition unit 134 acquires the character string of the signature portion from the email 1601, "Yamamoto A-ko, Business Department Manager, S Corporation, 105-0000 Tokyo...". The other user information acquisition unit 134 also searches the user information management table of FIG. 8 using the acquired character string of the signature portion. Next, the other user information acquisition unit 134 acquires other user information "<User ID> 1384 <Name> Yamamoto A-ko <Email address> ay@s.jp <Company name> S Corporation..." from the user information management table of FIG. 8. Here, the other user information acquisition unit 134 acquires the character string of the signature portion from the email, and acquires other user information from the user information management table using the character string. However, the other user information acquisition unit 134 may also acquire other user information using the character string of the signature portion from the email.

Next, the other user information acquisition unit 134 pairs the other user information with the user identifier "1001" and the type identifier "email" and accumulates the other user information in the storage unit 11. Note that such other user information is information that may potentially be the source of exchange relationship information.

Next, the exchange information determination unit 132 judges whether or not email 1602 in FIG. 16 satisfies all of the business exchange conditions for "ID=1, 2, 3" in FIG. 13. Here, the exchange information determination unit 132 judges that email 1601 in FIG. 16 does not satisfy the business exchange condition for "ID=1" because the sender's email address is "star@google.com". In other words, the exchange information determination unit 132 judges that email 1602 in FIG. 16 does not satisfy the business exchange conditions, and does not select it as exchange information that satisfies the predetermined conditions.

The interaction information determination unit 132 performs the above process on all the read emails. As a result, the interaction information determination unit 132 selects only email 1601 as interaction information that satisfies the predetermined conditions. The other user information acquisition unit 134 then stores only one piece of other user information corresponding to email 1601, paired with the user identifier "1001."

Next, the exchange information determination unit 132 refers to the calendar server 2(2) and reads out one or more pieces of schedule information (information having a start date and time, an end date and time, a title, etc.) that are paired with the user identifier "1001" from the calendar schedule information management table in FIG. 14. Note that the one or more pieces of schedule information that are paired with the user identifier "1001" includes the schedule information of "ID=1" in FIG. 14.

Then, the exchange information determination unit 132 judges whether or not one or more pieces of schedule information satisfy the business exchange condition of "ID=4" or "ID=5" in FIG. 13. Here, the exchange information determination unit 132 acquires the term "meeting" from the title of the calendar schedule information "XX meeting @ Y Company Aoki Jiro-san", detects that the term "meeting" of "ID=1" in FIG. 14 exists in the business terminology dictionary of FIG. 11, and judges that the business exchange condition of "ID=4" is satisfied. In addition, the exchange information determination unit 132 judges that the business exchange condition of "ID=5" in FIG. 13 is satisfied using the start date and time "2021/1/19 16:00" and end date and time "2021/1/19 17:00" of the calendar schedule information of "ID=1". Then, the exchange information determination unit 132 determines the calendar schedule information of "ID=1" in FIG. 14 as exchange information that satisfies the predetermined condition.

Next, the other user information acquisition unit 134 acquires other user information using the interaction information. Specifically, the other user information acquisition unit 134 searches the user information management table in FIG. 8 using "Y Company" and "Aoki Jiro" in the title "XX meeting @Y Company Aoki Jiro" and determines that it matches the record with "ID=3". Then, the other user information acquisition unit 134 acquires other user information "<User identifier> 1003 <Name> Aoki Jiro <Email address> aoki@y.com <Company name> Y Company....".

Next, the other user information acquisition unit 134 pairs the other user information with the user identifier "1001" and the type identifier "Calendar" and accumulates the other user information in the storage unit 11. Note that such other user information is information that may be the source of exchange relationship information.

The exchange information determination unit 132 performs the above process on all the calendar schedule information that it reads out. As a result, it is assumed that the exchange information determination unit 132 determines that the second and subsequent calendar schedule information retrieved from the calendar server 2 (2) do not satisfy the business exchange conditions of "ID=4" and "ID=5" in FIG. 13. Then, it is assumed that the exchange information determination unit 132 selects only the calendar schedule information of "ID=1" in FIG. 14 as exchange information that satisfies the predetermined conditions. Then, it is assumed that the other user information acquisition unit 134 accumulates only one piece of other user information that corresponds to the calendar schedule information of "ID=1" in FIG. 14, paired with the user identifier "1001".

Next, the exchange information determination unit 132 refers to the web conference server 2 (3) and reads out one or more pieces of web conference schedule information (information having start date and time, end date and time, topics, etc.) that are paired with the user identifier "1001" from the web conference schedule information management table in FIG. 15. Note that the one or more pieces of web conference schedule information that are paired with the user identifier "1001" includes the web conference schedule information of "ID=1" in FIG. 15.

Then, the exchange information determination unit 132 judges whether or not each of the one or more pieces of web conference schedule information satisfies the business exchange condition of "ID=6" in FIG. 13. Here, the exchange information determination unit 132 judges that the "start date and time, end date and time" of the web conference schedule information of "ID=1" in FIG. 15 satisfies the business exchange condition of "ID=6". Then, the exchange information determination unit 132 determines the web conference schedule information of "ID=1" in FIG. 15 as exchange information that satisfies the predetermined condition.

Next, the other user information acquisition unit 134 uses the interaction information to acquire other user information. Specifically, the other user information acquisition unit 134 extracts "X Co., Ltd." and "Suzuki B-ko" from the topic character string, and uses the terms to search the user information management table of FIG. 8 and determine that they match a certain record (not shown). The other user information acquisition unit 134 then acquires the other user information "<User identifier> 1058 <Name> Suzuki B-ko <Email address> sb@x.com <Company name> X Co., Ltd.".

Next, the other user information acquisition unit 134 pairs the other user information with the user identifier "1001" and the type identifier "web conference" and accumulates the other user information in the storage unit 11. Note that such other user information is information that may be the source of exchange relationship information.

The interaction information determination unit 132 performs the above process on all acquired web conference schedule information. As a result, the interaction information determination unit 132 determines that the second and subsequent web conference schedule information acquired from the web conference server 2 (3) does not satisfy the business interaction condition of "ID=6" in FIG. 13. The interaction information determination unit 132 then selects only the web conference schedule information of "ID=1" in FIG. 15 as interaction information that satisfies the predetermined condition. The other user information acquisition unit 134 then stores only one other user information corresponding to the web conference schedule information of "ID=1" in FIG. 15, paired with the user identifier "1001".

The above process is also performed on the user identifiers of other users.

(Specific Example 2)
Next, assume that user "Yamada Ichiro", identified by user identifier "1001", logs into the exchange management device 1 using his/her own terminal device 3. Then, after the login process, the processing unit 13 of the exchange management device 1 acquires one or more other user identifiers that are paired with the user identifier "1001" from the exchange relationship management table having the structure shown in FIG. 10. The exchange management device 1 acquires user information that is paired with each of the one or more other user identifiers from the user information management table. In addition, the exchange management device 1 acquires the number of other user information that is paired with the user identifier "1001", "3", using the other user information accumulated in the storage unit 11 in the process of specific example 1. Then, the exchange management device 1 constructs screen information including the acquired user information and the number of other user information "3", and transmits it to the terminal device 3.

Next, suppose that Yamada Ichiro's terminal device 3 receives the screen information and outputs the screen shown in FIG. 17. In FIG. 17, 1701 is user information of other users who have interactions with Yamada Ichiro. Also, 1702 is information for notifying the existence of other user information that has been stored in pairs with user identifier "1001." It can also be said that 1702 is information for notifying the existence of other user information that may be the source of exchange relationship information.

And suppose that Yamada Ichiro designates area 1702. The terminal device 3 then accepts this instruction and transmits an output instruction to the exchange management device 1 for a business card creation screen having the user identifier "1001." The business card creation screen can be said to be a creation screen for exchange relationship information.

Next, the receiving unit 12 of the exchange management device 1 receives an instruction to output the business card creation screen with the user identifier "1001."

Next, the questioning unit 133 obtains three pieces of other user information that are paired with the user identifier "1001" from the storage unit 11. Next, the questioning unit 133 uses the three pieces of other user information to construct inquiry screen information for inquiring whether or not to perform the business card creation process. Next, the questioning unit 133 transmits the inquiry screen information to Yamada Ichiro's terminal device 3. Note that the business card creation process here refers to the creation of exchange relationship information.

Next, Yamada Ichiro's terminal device 3 receives the inquiry screen information and outputs the inquiry screen. An example of such output is shown in FIG. 18. In FIG. 18, three pieces of other user information are displayed, and a "Create business card" button 2 is displayed for each piece of other user information. When a "Create business card" button (1801, 1802, 1803) is instructed, the user is instructed to create exchange relationship information using the other user information corresponding to the button.

And suppose that Yamada Ichiro selects all of the "Create business card" buttons 1801, 1802, and 1803 on the screen in FIG. 18.

Next, Yamada Ichiro's terminal device 3 accepts the instruction and sends a response to the interaction management device 1 indicating that the interaction relationship information will be stored for each of the three pieces of other user information.

Next, the questioning unit 133 of the exchange management device 1 receives a response indicating that exchange relationship information will be accumulated for each of the three pieces of other user information.

Next, the exchange relationship storage unit 135 uses the other user information corresponding to the "Create business card" button 1801 to obtain the exchange relationship information "<Received date and time> 2021/1/15 18:00:07 <Title> XX business negotiation <Body>...", the other user identifier "1384", and the type identifier "email", and stores this set of information in the exchange relationship management table of FIG. 10 in association with the user identifier "1001". This information is the record of 1001 in FIG. 10.

The exchange relationship storage unit 135 also uses the other user information corresponding to the "Create business card" button 1802 to acquire the exchange relationship information "<Start date and time> 2021/1/19 16:00 <End date and time> 2021/1/19 17:00 <Location> Y Company <Other> ○○ Meeting", the other user identifier "1003", and the type identifier "Calendar", and stores this set of information in the exchange relationship management table of FIG. 10 in association with the user identifier "1001". This information is the record of 1002 in FIG. 10.

The exchange relationship storage unit 135 also uses the other user information corresponding to the "Create business card" button 1803 to acquire the exchange relationship information "<Start date and time> 2021/1/25 13:00 <End date and time> 2021/1/25 14:00 <Tobic> Regarding the alliance...", the other user identifier "1058", and the type identifier "Web conference", and stores this set of information in the exchange relationship management table of FIG. 10 in association with the user identifier "1001". This information is the record of 1003 in FIG. 10.

Through the above process, relationship information can be accumulated using email, calendar schedule information, or web conference schedule information.

(Specific Example 3)
On January 18, 2021, Yamada Ichiro inputs business card information including a business card image of "Tanaka Hanako," with whom he exchanged business cards, and a registration instruction to the terminal device 3. The terminal device 3 then accepts the business card information and the registration instruction, and transmits the business card information and a registration instruction including the user identifier "1001" to the interaction management device 1.

Next, the business card information receiving unit 121 of the exchange management device 1 receives a registration instruction that includes the business card information and the user identifier "1001."

Next, the other user information acquisition unit 134 acquires the received business card information. Next, the other user information acquisition unit 134 uses the business card information to search the user information management table in FIG. 8 and acquires the other user identifier "1002." In addition, the other user information acquisition unit 134 acquires today's date "2021/1/18" (registration date) from a clock (not shown).

Next, the exchange relationship storage unit 135 stores exchange relationship information including the other user identifier "1002", the type identifier "business card", and the registration date "2021/1/18" in the exchange relationship management table of FIG. 10. Such information is record 1004 in FIG. 10.

As mentioned above, we were able to accumulate information on social relationships by registering business card exchanges.

As described above, according to this embodiment, it is possible to obtain and manage exchange relationship information regarding the ties between users using exchange information such as email, calendar schedule information, and web conference schedule information.
