Description

  The present invention relates to a mail management apparatus, a mail management method, and a mail management program, and more particularly to a mail management apparatus, a mail management method, and a mail management program for managing received mail.

  There is a case where it is necessary to grasp a trend of a topic in a user group as trend information. As an example, such a need may arise in a department that performs planning work in a company.

  In other words, the purpose of the activities of the department that conducts the planning work is to provide direction to the upper level with a broad view and to show the direction to the development department. This is because it is essential to collect the latest trend information held by the development department and analyze the ideal form and direction.

  The department that develops technology holds information about the technology that it is currently working on and peripheral information such as the latest trends related to that technology. However, the latest trend information held by such development departments is not written in a format such as technical reports, and is not clearly written, and is shared within the development department in a semi-implicit manner. There are many.

  Therefore, the latest trend information may not be obtained only by analyzing a format (document) such as a technical report. In addition, the latest trend information cannot be obtained even when waiting for external release in the form of a technical research report.

  Therefore, as a method for grasping the trend information in such a user group, there is a method for acquiring information using mail in the user group.

  That is, in the above example, as a method of obtaining the latest trend in the development department, there is an information acquisition from an email in the development department. This is because, within the development department, email is frequently used as a method for sharing the latest trends and the like, and it is considered that a lot of fresh information is included. For example, there may be a case where a web report or sharing of feelings as a result of investigating a paper or feelings is sent to a group by email and other members who have seen the email give their opinions.

  As the simplest method for acquiring information from an email, it is possible to transfer the email distributed in the development department to the planning department as it is.

  However, with this method, when the number of mails is enormous, it may be difficult for the planning department to efficiently acquire trend information. This is because many mails having contents unrelated to the trend information are included, and it is necessary to extract mails regarding the trend information from the mails.

  Japanese Patent Laying-Open No. 2009-237676 (hereinafter referred to as Patent Document 1) discloses a technique for extracting words related to the user's interest from the user's behavior and the like and performing a search using those words as search keywords. . Thereby, the user does not need to select and input the search key, and can easily execute the search.

  For example, a method of selecting necessary mails using keywords by applying the above-described technique disclosed in Patent Document 1 to the above-described problem can be cited.

  On the other hand, as a method of paying attention to an action of a person related to mail, Japanese Patent Laid-Open No. 2005-063138 (hereinafter referred to as Patent Document 2) discloses predetermined information such as exchange of e-mails and joint work of a plurality of computers by collaboration software. A technique is disclosed in which keywords used for database search are extracted from text obtained through activities and transmitted to a server.

  Using this technology, there is a method of estimating the direction of information distribution by focusing on e-mail exchange (action in the mailer) and extracting information providing or information receiving mail.

  This hardware configuration is a general computer hardware configuration. For this reason, the information processing apparatus 200 and the information management apparatus 300 have the same hardware configuration.

<Overview of operation>
The information processing apparatus 200 is assumed to be used by a user belonging to the development department for browsing a WEB page and sending / receiving mail.

  It is assumed that the mail management apparatus 100 and the information management apparatus 300 are used by users belonging to the planning department to acquire trend information in the development department based on the mail received by the information processing apparatus 200. Here, the trend information refers to the latest information in the target group, such as information related to the current work and peripheral information such as the latest trend related to the work.

  The mail management apparatus 100 selects a mail related to the trend information among the mails received by the information processing apparatus 200 based on the information related to the mail received using the information processing apparatus 200. Information related to mail refers to information indicating access to information related to the content of received mail, that is, information indicating the action taken by the user who received the received mail as a base point, for example, via the Internet When another device is accessed, when the other device is accessed via a predetermined range of network such as an address of the other device on the Internet, such as a corporate network called an intranet, the other device The address on the network. When such information exists, the mail management apparatus 100 selects the received mail as a mail related to the trend information.

  Specifically, when a user belonging to the development department browses a WEB page using the information processing apparatus 200A to find technical topic information (external URL), and copies and pastes it to send an email to another user belonging to the development department To do.

  The other user who received the mail by the information processing apparatus 200B clicks the technical topic information (external URL) in the received mail and accesses the WEB page. Alternatively, a keyword is copied and pasted from the received mail and WEB search is performed, and an external source is browsed.

  The mail management apparatus 100 detects the action after receiving the mail in the information processing apparatus 200B, and selects the transmitted / received mail as the target mail when the action is access to information. Then, the selected mail is analyzed to create a summary and transmitted to the information management apparatus 300.

<Functional configuration>
FIG. 2 is a block diagram showing a specific example of the functional configuration of the mail management apparatus 100 and the configuration of the storage area configured in the HDD 13 for performing the above operation. The functions shown in the block diagram of FIG. 2 are mainly formed on the CPU 10 when the CPU 10 of the mail management apparatus 100 reads out a program stored in the ROM 11 and develops it on the RAM 12 for execution. . However, at least a part thereof may be configured by hardware such as an electric circuit.

  Referring to FIG. 2, the HDD 13 has a mail holding unit 131 that is an area for holding mail, an activity log holding unit 132 that is an area for holding an activity log, and attributes for each user as a database. A personal attribute database (DB) 133 which is a storage area is included.

  Here, the activity log refers to the operation history related to the target mail in the operation history of the information processing apparatus 200.

  Further, referring to FIG. 2, the CPU 10 of the mail management apparatus 100 includes a mail acquisition unit 101 for acquiring a mail transmitted from the information processing apparatus 200 to another apparatus via the communication I / F 14, and the acquisition. Storage unit 102 for storing the information of the received mail as mail information in mail holding unit 131, history acquisition unit 103 for acquiring the operation history of information processing apparatus 200 via communication I / F 14, The operation history related to the mail transmission / reception and the operation history related to the mail is extracted as an activity log and recorded in the activity log holding unit 132, and the operation history is recorded based on the recorded activity log. A calculation unit 105 for calculating the importance level, and a reading unit 1 for reading target mail information from the mail holding unit 131 according to the calculated importance level. Includes a 6, a generating unit 107 for generating a read analyzes the mail information summary information, and a providing unit 108 for providing the generated summary information to the information management apparatus 300.

  When the mail management apparatus 100 functions as a mail server, the mail acquisition unit 101 acquires mail received from the information processing apparatus 200 as a server. When the mail management apparatus 100 does not function as a mail server, the mail acquisition unit 101 accesses a mail server (not shown) and acquires the mail received by the information processing apparatus 200.

  The HDD 23 of the information processing apparatus 200 includes a holding area (not shown) for holding an operation history. The history acquisition unit 103 may acquire the operation history by accessing the holding area at a predetermined timing, or requests the information processing apparatus 200 to transmit the operation history at a predetermined timing, and responds to the request The operation history may be acquired by receiving the transmitted operation history.

  The recording unit 104 analyzes the acquired operation history and extracts, for each mail information held in the mail holding unit 131, an operation history representing an operation in the information processing apparatus 200 within a predetermined period after receiving the mail. . Then, the extracted operation history is recorded in the activity log holding unit 132 as an activity log in association with the corresponding mail information. An example of the association here is a method of giving unique information of mail information such as a message ID described in the mail header to the operation history.

  Based on the operation history recorded as the activity log in the activity log holding unit 132, the calculation unit 105 selects an email having a high possibility of being related to the latest trend information as the target email. There are several calculation methods as this method. Therefore, a specific calculation method will be described below by giving a first example to a fifth example.

  As a first example, the calculation unit 105 refers to an operation history recorded as an activity log in the activity log holding unit 132 and is associated with an operation history representing an operation for accessing some information after receiving a mail. Selected e-mail information as the target e-mail.

Examples of operations to access some information after receiving mail include the following:
・ Mailer operation logs (email reply, mail transfer, etc.),
・ Print execution
・ Web page browsing
・ WEB search,
・ Send mail after WEB search,
・ Send mail including URL,
・ Copy the word in the received mail, then WEB search,
-Click on the URL in the received mail.

  As a second example, the calculation unit 105 calculates the importance of the activity log in order to select mail according to the importance of the operation content. Here, it calculates so that a high point may be added compared with another operation with respect to the operation for accessing some information especially among operation content. This is because access to other devices than the mailer operation (for example, WEB search using keywords, click on URL in received mail, etc.) is access to technical trend information. This is because the possibility is high.

  Therefore, when calculating the second example, the calculation unit 105 stores a correspondence between the operation content and the importance in advance, and calculates the importance for each activity log with reference to the correspondence.

  FIG. 3 is a diagram illustrating a specific example of the correspondence between the operation content stored in the calculation unit 105 and the importance when the calculation of the second example is performed. Referring to FIG. 3, for example, the operation content analyzed from the activity log is more important in terms of the importance of the WEB search using the keyword or the WEB search by clicking the URL in the received mail. It is set higher than importance.

  The calculating unit 105 specifies the importance level of the activity log with reference to the correspondence in FIG. 3, and calculates the cumulative value of the importance level for each associated mail information. Then, mail information whose cumulative value is equal to or greater than a preset threshold value is selected as a target mail.

  FIG. 4 is a diagram illustrating a specific example of the cumulative value calculated for each piece of mail information. In FIG. 4, for each piece of mail information, the importance of the operation history of each user who has received the mail as the activity log is specified, and the accumulated value is calculated.

  Specifically, with reference to FIG. 4, seven operation histories by four users are associated with the mail information of message ID 000112. As an example, an operation history indicating an operation IDYA0012 representing an operation of sending a mail after a WEB search is associated as an operation history of the user represented by ID12334.

  The calculation unit 105 identifies the importance level with reference to the correspondence of FIG. 3 for the operation content indicated in each activity log, and calculates the cumulative value of the importance level for each mail information. In the example of FIG. 4, 100 is used as the threshold value, and the calculation unit 105 selects mail information represented by the message ID 000112 and the message ID 105200 having a calculated cumulative value of 100 or more as the target mail. ing.

  As a third example, the calculation unit 105 calculates the importance of the operation content in consideration of the degree of access to the information of the user who received the mail. As an example, as shown in FIG. 4, each of a plurality of users who have received a mail may operate the information processing apparatus 200 within a predetermined time after reception, and the operation content is an access to some information. In such a case, the calculation unit 105 calculates so as to add higher points as the number of users who have performed the operation increases. This is because the more users who access the information after receiving the mail, the higher the possibility that the mail is related to the latest trend information.

  Therefore, when performing the calculation of the third example, the calculation unit 105 includes a user's operation whose operation content is an operation for accessing some information as described above in the operation history associated with the mail information as the activity log. Calculate the importance that represents the number of people. Then, mail information whose importance is equal to or higher than a predetermined threshold value is selected as a target mail.

  As another example of the degree of access to information, the importance of the operation content may be calculated based on the attribute of the accessed information itself. Specifically, there is an example in which the distance from the information processing apparatus 200 that receives the mail to the information to be accessed is indexed and used as a distance index.

  FIG. 5 is a diagram illustrating a specific example of the relationship between the network definition and the distance index for each type of information. Referring to FIG. 5, the type corresponding to the distance from the group to which the user using the information processing apparatus 200 belongs to the information as the type of information depends on the access information of the apparatus storing the information. It is prescribed. And the higher importance is prescribed | regulated, so that the said distance is large. This is because the more distant information is accessed after the mail is received, the higher the possibility that the mail is related to the latest trend information.

  Therefore, in this case, the calculation unit 105 calculates the importance of the activity log representing an operation for accessing some information in the activity log based on the distance index of the information with reference to the correspondence in FIG. To do. Then, mail information whose importance is equal to or higher than a predetermined threshold value is selected as a target mail.

  As a fourth example, the calculation unit 105 calculates the importance of the operation content in consideration of the period from the opening time of the received mail to the time when the operation for accessing information is executed. That is, the calculation unit 105 performs calculation so that a higher point is added as the period is shorter. This is because it is considered that the shorter the period, the higher the priority than other mail, and the higher the possibility that the mail has contents related to the latest trend information.

  Therefore, when performing the calculation of the fourth example, the calculation unit 105 performs the operation history indicating the opening operation of the received mail with respect to the activity log of the same user among the activity logs associated with the mail information, as described above. An operation history having the earliest operation time is extracted from operation histories indicating operations for accessing various information, a period between these operation times is calculated, and an importance level representing the period is calculated. Then, mail information whose importance is equal to or higher than a predetermined threshold value is selected as a target mail.

  As a fifth example, the calculation unit 105 calculates the importance of the operation content based on the attribute of the user associated with the operation history of accessing the information after receiving the mail. That is, the calculation unit 105 calculates so as to add a high point when the user attribute associated with such an operation history is a predetermined attribute. This is because, for example, a user with a predetermined attribute such as a manager or a key person is likely to handle the latest trend information.

  Therefore, when calculating the fifth example, the calculation unit 105 stores the correspondence between the user attribute and the importance in advance, and calculates the importance for each activity log with reference to the correspondence. Here, as the above correspondence, for example, a high importance level is defined for a predetermined attribute such as a manager or a key person, and a low importance level is defined for an attribute that is not.

  The calculation unit 105 analyzes the activity log and identifies the user who performed the operation, identifies the attribute of the user with reference to the human attribute DB 133, refers to the correspondence, and based on the attribute Identify the importance of the activity log. The calculating unit 105 calculates a cumulative value of importance for each piece of associated mail information, and selects mail information whose cumulative value is equal to or greater than a preset threshold value as a target mail.

  In the second to fifth examples, the calculation unit 105 calculates the importance for each mail information and compares the importance with a fixed threshold value stored in advance. Although the target mail is selected, the calculation unit 105 may set the threshold value itself.

  As an example, the calculation unit 105 sets a threshold value based on a period from when an e-mail is received until an operation for accessing information is performed. Specifically, the threshold value is set to be lower as the period is shorter. This is because the shorter the period, the higher the priority than other mails, and the higher the possibility that the mails are related to the latest trend information. The lower the threshold is set, the more mail is selected.

  In this case, the calculation unit 105 stores the correspondence between the period and the threshold value in advance. As an example, for the activity log of the same user among the activity logs associated with the mail information, the calculation unit 105 includes an operation history indicating reception of the received mail and an operation history indicating an operation for accessing the above information. The operation history with the earliest operation time is extracted, the period between these operation times is calculated, and the threshold corresponding to that period is specified as the threshold for the mail information.

  Note that the calculation unit 105 may perform combinations of the calculation methods shown in the first to fifth examples described above that can be combined.

  When the reading unit 106 receives the information specifying the selected mail from the calculation unit 105, the reading unit 106 reads the mail information specified by the information from the mail holding unit 131 and passes it to the generation unit 107.

  The generation unit 107 analyzes the mail information and generates summary information. As a method for generating summary information in the generation unit 107, a general method adopted by a commercially available sentence summary tool or the like is adopted. The created summary information is passed to the providing unit 108.

  The providing unit 108 provides summary information to the information management apparatus 300. The method is not limited to a specific method. As an example, it may be sent by e-mail, or may be posted on a system that can be browsed only by authorized users, such as other devices accessed via an in-house intranet or the Internet.

  In this example, it is assumed that only the summary information is provided to the information management apparatus 300 and the email information itself is not provided, but the email information itself selected by the calculation unit 105 or the email in addition to the summary information is sent. Information may be provided to the information management apparatus 300.

<Operation flow>
FIG. 6 is a flowchart showing a specific example of the flow of operations for recording an activity log related to mail received by the information processing apparatus 200 in the mail management apparatus 100. The operation shown in the flowchart of FIG. 6 is realized by causing the CPU 10 of the mail management apparatus 100 to read out a program stored in the ROM 11 and execute it on the RAM 12 to exhibit each function shown in FIG.

  Referring to FIG. 6, when CPU 10 obtains an operation history from information processing apparatus 200 in step S101, for each piece of mail information held in mail holding unit 131, the operation history is within a predetermined time after receiving the mail. It is confirmed whether or not it represents an operation performed.

  As a result, if it is determined that any of the mail information indicates that the operation history represents an operation performed within a predetermined time after receiving the mail (YES in step S103), the CPU 10 in step S105 The operation history is recorded in the activity log holding unit 132 as an activity log associated with the mail information.

  Further, FIG. 7 is a flowchart showing a specific example of an operation flow for providing the information management apparatus 300 with trend information in the development department in which the information processing apparatus 200 is used in the mail management apparatus 100. The operation shown in the flowchart of FIG. 7 is also realized by causing the CPU 10 of the mail management apparatus 100 to read out a program stored in the ROM 11 and execute it on the RAM 12 to exhibit the functions shown in FIG.

  In FIG. 7, the calculation unit 105 calculates the importance of the activity log as described in the second to fifth examples, calculates the cumulative value for each mail information, and the value is This shows a case where an email that is equal to or greater than the threshold is selected as the target email.

  That is, referring to FIG. 7, in step S <b> 201, the CPU 10 extracts an activity log related to the mail from the activity log holding unit 132 for the mail information held in the mail holding unit 131. In step S203, the CPU 10 calculates the importance of the activity log.

  The CPU 10 repeats the above steps S201 to S203 to calculate the importance level for all activity logs related to the mail recorded in the activity log holding unit 132 (NO in step S205), and in step S207 the mail The cumulative value for is calculated.

  If the cumulative value calculated in step S207 is equal to or greater than a predetermined threshold value or a preset threshold value (YES in step S209), the CPU 10 analyzes the mail information in step S211 with the mail as a target mail. To generate summary information. In step S <b> 213, the CPU 10 provides the generated summary information to the information management apparatus 300.
