Description

The present invention relates to an electronic mail system that distributes an electronic document via a network, and more particularly to a user response management method for the contents indicated by the electronic document in the electronic mail system.

With the spread of networks, electronic mail is increasingly used for communication in daily work. When the number of exchanged e-mails becomes large, the recipient cannot perform proper processing, and the received e-mails are only stored in the recipient's terminal device.

  In some cases, an e-mail message exchanged in an e-mail system requires a reply from a recipient, and it is necessary to send a reply by a time limit designated by a sender who desires a reply. However, it is difficult to manage without overlooking an electronic mail that requires a reply among electronic mails exchanged in large quantities. In particular, if an important email such as an inquiry from a customer is overlooked, it may cause a complaint.

In view of this, a technique for selecting e-mails such as inquiries from customers from a plurality of received e-mails has been proposed. For example, in Patent Document 1, a system that analyzes the content of a received mail, determines that an e-mail containing a pre-registered word / phrase is necessary for reply, and creates a reply e-mail using a pre-registered answer sentence template. It is disclosed.
JP 2002-49564 A

In the electronic mail system, when the number of electronic mails to be exchanged becomes large, the received electronic mails are only accumulated in the terminal device of the recipient, and cannot be appropriately processed on the recipient side. Even if mail to be answered is extracted from mails received using the method of Patent Document 1, the same problem occurs when there are a large number of extracted mails. Due to this problem, it is not possible to immediately reply to important mails such as inquiries from customers, which may cause complaints.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a mail system that enables a recipient of an e-mail to determine the priority of mail to be answered.

The present invention relates to a mail transmission / reception program that causes a computer to function as a mail transmission / reception device that receives an electronic mail stored in a mail server in an electronic mail system and transmits the electronic mail to the mail server. Character pattern storage means for storing, sentence analysis means for analyzing whether or not the words stored in the character pattern storage means are included in the received e-mail, and stored in the character pattern storage means Analysis information storage means for storing a rate of reply to the e-mail containing the word for each word, and the analysis information corresponding to the word analyzed to be included in the e-mail by the sentence analysis means A computer is used as a reply determination means for determining whether or not a reply is necessary based on the ratio stored in the storage means. Characterized in that to.

In the present invention, e-mails that require replies such as inquiries from customers are automatically selected, and it is possible to determine the priority order of e-mails to be replied. Necessary e-mails can be processed appropriately.

  In addition, by accumulating user responses to emails received in the past, it becomes possible to determine whether or not a reply is necessary based on the user's response to emails having contents similar to the received email, and the accuracy of the determination is improved. Can be improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a configuration of a mail transmitting / receiving apparatus 100 of the present invention. 1 includes a text analysis unit 200, a reply determination unit 300, a mail information management unit 400, a reply prompting unit 500, a display control unit 600, and a syntax analysis unit 700. Further, it has sentence analysis information 800, a character pattern table 900, a mail box 1000, and mail management information 1100.

  The sentence analysis unit 200 analyzes the mail text when receiving mail, matches the character pattern table 900, registers or updates the matched character pattern information in the sentence analysis information 800, and analyzes the mail management information 1100 (a). Register the result.

  The reply determination unit 300 determines whether or not a reply to the received mail is necessary based on the analysis result of the sentence analysis unit 200. Further, the reply determination flag of the mail management information 1100 (a) is set based on the result of the necessity determination of reply.

  The mail information management unit 400 detects that a reply mail for the received mail has been transmitted, and updates the mail management information 1100. When the transmitted mail is a reply mail for the received mail determined to be necessary for reply by the reply determination unit 300, the mail management information 1100 is updated and the analysis information is updated. On the other hand, when the transmitted mail is a reply mail for a received mail that is not determined to be necessary for reply by the reply determination unit 300, the character pattern information is registered in the character pattern table 900 using the syntax analysis unit 700.

  The reply reminder 500 compares the reception date registered in the mail management information 1100 (a) with the system date, and notifies the user of a reminder message for prompting a reply for a certain period of time.

  The display control unit 600 controls the list display format of received mail based on the mail management information 1100 (a) and the sentence analysis information 800.

  The syntax analysis unit 700 divides the content of the mail body into words using a known syntax analysis method, and registers it in the character pattern table 900.

  FIG. 2 shows an example of the contents of the sentence analysis information 800. As shown in FIG. 2, the sentence analysis information 800 includes a combination number 801, analysis accuracy 802, reception count 803, reply count 804, and update date 805.

  FIG. 3 shows an example of the contents of the character pattern table 900. As shown in FIG. 3, the character pattern table 900 includes a first pattern table (a) including a management number 901 and a first word / phrase 902, and a second pattern table including a branch number 903 and a second word / phrase 904. (b).

  FIG. 8 shows an example of the contents of the mailbox 1000. As shown in FIG. 8, the mailbox 1000 includes a mail number 1001, a sender 1002, a destination 1003, a subject 1004, a transmission date and time 1005, and a text 1006.

  FIG. 4 shows an example of the contents of the mail management information 1100. As shown in FIG. 4, the mail management information 1100 includes a mail number 1101, a reception date 1102, a reply date 1103, a status flag 1104 indicating a mail status such as whether or not a reply mail has been transmitted, a mail A reply determination flag 1105 indicating whether or not the reply determination unit 300 has determined that a reply is necessary, and the character pattern table that the sentence analysis unit 200 has determined to match when matching the character pattern table 900 against the mail. It is configured to include combination information 1106 having a combination number 1160-1 indicating the combination of the first word and the second word and the number of occurrences 1106-2 in the mail.

  The above is the configuration of the mail transmitting / receiving apparatus of the present invention.

  Next, the flow of processing when a mail is received by the mail transmitting / receiving apparatus of the present invention will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of processing when mail is received.

  First, the mail transmission / reception apparatus receives mail from the mail server using an existing communication protocol (S101). The received mail includes attribute information including information about the sender, transmission date, mail subject, and the like, and a mail text.

  Next, the mail transmitting / receiving apparatus uses the sentence analysis unit 200 to analyze the attribute information of the received mail and the mail text (S102). In the mail body analysis process (S102) described above, the combination of the first word / phrase 902 and the second word / phrase 903 registered in the character pattern table 900 is matched with the mail body, and appears for each matching combination. Analyze the number of times For example, from the beginning of the body of the email, analyze the part where the phrase that matches the "answer" registered in the first phrase 902 exists, and within a few characters from the part where the phrase that matches the "answer" exists It is determined whether or not there is a phrase registered in the second phrase 904. It is also possible to employ a configuration in which analysis processing is performed using a combination with high analysis accuracy 802 of the sentence analysis information 800, and analysis processing is not performed with a combination with extremely low analysis accuracy 802. Further, the analysis processing may not be performed for a combination in which the difference between the update date 805 of the text analysis information 800 and the system date exceeds a predetermined number of days.

  In the example shown in FIG. 3, four words “request”, “wait”, “letter”, and “notice” are shown as the words registered in the second word 904, and the backward from the position that matches the first word 902. It is determined whether or not there is a phrase that matches these four phrases within a few characters. Here, the last few characters are automatically removed from the text of the mail body when sending and receiving mail, in addition to removing the influence of particles etc. inserted between the first and second words. This is to remove the influence of a line feed or a space character inserted in the. Note that the number of characters is set in advance.

  Next, the mail transmitting / receiving apparatus registers the result of the analysis process (S102) in the sentence analysis information 800. In the example illustrated in FIG. 2, the combination of the first phrase “answer” and the second phrase “wait” is registered as a combination number 801 “001-02”. An example sentence that matches this combination is "We are looking forward to your response."

  Also, the combination number 801 of the analysis information 800 shown in FIG. 2 shows an example of a notation format in which the management number 901 for the first word / phrase 902 and the branch number 903 for the second word / phrase 904 are concatenated with “-”. Yes.

  In the process of registering the sentence analysis information 800, when the combination number of the result of the analysis process has already been registered in the sentence analysis information 800, the number of receptions 803 and the update of the sentence analysis information 800 corresponding to the combination number of the result of the analysis process Update day 805. The analysis process of the attribute information of the received mail is the same as the analysis process in the conventional mail transmitting / receiving apparatus.

  After the analysis process described above is completed, the mail transmitting / receiving apparatus registers the information obtained in the analysis process (S102) for the received mail in the mail management information 1100 (a) (S103). The mail number 1101 for specifying the received mail may be assigned by the mail transmitting / receiving device when receiving the mail, or an identification number included in the attribute information of the received mail may be used. The status flag 1104 is set to “0” indicating unopened.

  Next, when an analysis result determined to require a reply is obtained in the analysis process (S102) (YES in S104), the reply determination flag 1105 is set to “1” (S105). In the reply necessity determination process described above, the average analysis accuracy of the combination of the first word and the second word of the character pattern table detected in the analysis process in the sentence analysis unit 200 and the necessity determination threshold value Is compared to determine whether or not a reply is necessary. For example, when the combination numbers 801 “001-02” and “002-03” are detected once in the analysis process (S102), in the example shown in FIG. 2, the combination number 801 “001-02” The analysis accuracy 802 “68” is set for the analysis accuracy 802 “99” and the combination number 801 “002-03”, and the average analysis accuracy is “84”. Here, when the necessity determination threshold is set to “60”, the received mail in which the combination having the above average analysis accuracy is detected is determined as needing a reply.

  Note that a second threshold value having a value equal to or smaller than the threshold value for determining necessity is provided, and a combination of analysis accuracy smaller than the second threshold value is removed when obtaining the above-mentioned average analysis accuracy. good. For example, in addition to the above example, when the combination of the combination number 801 “004-02” is detected once more in the analysis process (S102), in the example shown in FIG. Analysis accuracy 802 “4” is set, and in the above example, the average analysis accuracy is “57”. Similarly to the above-described example, when the necessity determination threshold is set to “60”, the received mail in which the combination having the above-described average analysis accuracy is detected is not determined as needing a reply. Therefore, it is possible to remove combinations with extremely low analysis accuracy by performing comparison with the second threshold value before obtaining the average analysis accuracy.

  In addition, the above analysis accuracy is determined based on whether or not a reply is required by selecting one analysis accuracy having the largest value from the combinations detected in the analysis processing and comparing the analysis accuracy with a threshold for determining necessity. It may be a thing that judges. Furthermore, the above-mentioned reply necessity determination is based on the presence / absence of a reply based only on the presence / absence of a combination of the first word / phrase and the second word / phrase in the character pattern table detected in the analysis processing by the sentence analysis unit 200. May be used.

  In the example shown in FIG. 4, as received mail management information identified by the mail number 1101 “R0001”, the received date 1102 “2004/02/01”, the reply date 1103 “2004/02/01”, the status flag 1104 “ 2 ”, reply judgment flag 1105“ 1 ”, combination information 1106, occurrence number 1106-2“ 001-02 ”for combination number 1106-1“ 001-02 ”, for combination number 1106-1“ 002-03 ” The number of occurrences 1106-2 “1” is registered for the number of occurrences 1106-2 “1” and the combination number 1106-1 “004-02”.

  In the above example, the status flag 1104 “2” indicates that a reply mail for the received mail identified by the mail number 1101 “R0001” has been transmitted. The status flag 1104 “1” means that the received mail specified by the mail number 1101 has been opened and the recipient has viewed the mail text. If the status flag 1104 “0”, the mail number This means that the received mail specified by 1101 is unopened.

  In addition, the reply determination flag 1105 “1” for the mail number 1101 “R0001” indicates that the reply determination unit 300 determines that the reply needs to be sent, and the reply is determined not to be necessary. Becomes “0”.

  After completing the registration process to the mail management information 1100 (a), the mail transmitting / receiving apparatus stores the received mail in the mailbox 1000 and performs a display control process (S106) described later.

  The above is the flow of processing when the mail transmitting / receiving apparatus receives mail.

  Next, the flow of processing when creating a mail in the mail transmitting / receiving apparatus will be described. First, the mail creating process is started by the user of the mail transmitting / receiving apparatus performing an operation for instructing mail creation. In the mail creation process, the mail transmission / reception apparatus assigns a mail number 1107 that can be uniquely identified to the created mail, and registers it in the mail management information 1100 (b) together with the creation date 1109.

  Further, the mail transmitting / receiving apparatus sets the mail number of the received mail to the reference source mail number 1108 when the content of the mail creation instruction by the user is creation of a reply mail to the received mail. In the example shown in FIG. 4, the reference source mail number 1108 “R0001” is set for the mail number 1107 “S0001”. This indicates that the outgoing mail specified by the mail number 1107 “S0001” is a reply mail to the received mail uniquely identified by the mail number 1101 “R0001” registered in the mail management information 1100 (a). Show.

  The above is the flow of processing when creating a mail in the mail transmitting / receiving apparatus.

  Next, the flow of processing at the time of mail transmission by the mail transmitting / receiving apparatus will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of the mail transmission process.

  First, when the user of the mail transmission / reception apparatus performs a pressing operation of a send button for instructing mail transmission (S201), the mail transmission / reception apparatus executes mail transmission processing using an existing communication protocol (S202). .

  After the mail transmission process (S202), the mail transmitting / receiving apparatus sets the transmission date 1110 of the mail management information 1100 (b) for the mail number 1107 assigned to the transmitted mail (S203).

  Next, the mail transmitting / receiving apparatus determines whether or not the mail transmitted in the above transmission process (S202) is a reply mail to the received mail (S204). In the determination process (S204) described above, whether or not the reference mail number 1108 is set in the mail management information 1100 (b) corresponding to the mail number 1107 assigned to the outgoing mail in the mail creation process described above. The determination is performed by the mail information management unit 400. In the example shown in FIG. 4, since the reference source mail number 1108 “R0001” is set for the mail number 1107 “S0001”, it is determined as a reply mail. On the other hand, since the reference mail number is not set for the mail number “S0004”, it is determined that the mail is a new mail.

  When the mail transmitting / receiving apparatus determines in the above-described determination process that the mail transmitted in the above-described transmission process (S202) is a reply mail to the received mail (YES in S204), the status flag of the mail management information 1100 (a) 1104 is updated to “2” (S205). The status flag 1104 to be updated is the mail management information 1100 (a) corresponding to the same mail number 1101 as the reference mail number 1108 of the mail management information 1100 (b) corresponding to the mail number 1107 assigned to the outgoing mail. State flag 1104.

  Next, the mail transmitting / receiving apparatus determines whether or not the mail transmitted in the above-described transmission process (S202) is a reply mail for the received mail determined as needing a reply by the reply determination unit 300 (S206). In the determination process (S206) described above, the mail management information 1100 (a) corresponding to the same mail number 1101 as the reference mail number 1108 of the mail management information 1100 (b) corresponding to the mail number 1107 assigned to the outgoing mail ) Reply determination flag 1105 is determined as “1”. In the example shown in FIG. 4, the received mail specified by the reference mail number 1108 “R0001” set in the mail management information 1100 (b) of the outgoing mail specified by the mail number 1107 “S0001” Since the reply determination flag 1105 is set to “1” in the information 1100 (a), this indicates that the reply determination unit 300 determines that a reply is necessary. On the other hand, the received mail specified by the reference mail number 11008 “R0002” of the mail management information 1100 (b) of the outgoing mail specified by the mail number 1107 “S0002” is the reply determination flag in the mail management information 1100 (a). Since 1105 is set to “0”, it indicates that the reply determination unit 300 did not determine that a reply is necessary.

  In the above-described determination process (S206), when it is determined that the transmitted mail is a reply mail for the received mail that is determined to require a reply (YES in S206), the mail transmitting / receiving apparatus sets the reply count 804 of the analysis information 800. Update (S207). The number of replies 804 to be updated is the number of replies of the sentence analysis information 800 having the same combination number 801 as the combination number 1106-1 of the mail management information 1100 (b) corresponding to the mail number 1107 assigned to the transmitted mail. 804. In the example shown in FIG. 4, the received mail specified by the reference mail number 1108 “R0001” of the mail management information 1100 (b) of the outgoing mail specified by the mail number 1107 “S0001” is the mail management information 1100 ( “001-02” and “002-03” are registered as the combination number 1106-1 of a). In the example shown in FIG. 2, “69” is shown for the combination number 801 “001-02” as the number of replies 804 of the sentence analysis information 800 having the same combination number 801, and “ “70”, “34” is indicated for the combination number 801 “002-03”, and “35” is obtained by the update process. Further, the mail transmission / reception apparatus performs the update process of the analysis accuracy 802 and the update date 805 on the sentence analysis information 800 in which the reply count 804 is updated in the update process (S207) described above, and then performs a display control process (S208 described later). )I do.

  In the above-described process of updating the analysis accuracy 802 (S207), the ratio of the number of replies 804 to the number of receptions 803 of the sentence analysis information 800 is calculated. In the example illustrated in FIG. 2, the number of receptions 803 “70” and the number of replies 804 “69” are set as the sentence analysis information 800 for the combination number 801 “001-02”. Analysis accuracy 802 "99" is set. Through the above update process (S207), the reply count 804 of the analysis information 800 for the combination number 801 “001-02” is “70”, and the analysis accuracy 802 is updated to “100”.

  On the other hand, when it is determined in the above-described determination process (S206) that the transmitted mail is a reply mail for the received mail that has not been determined to require a reply (NO in S206), the mail transmitting / receiving apparatus causes the syntax analysis unit 700 to Use the extracted morphological analysis method to extract one or more words from the body of the received mail that is the reference source for the sent mail, and register the extracted words in the character pattern table 900 (S209). The display control process (S208) is performed. For example, by performing the above morphological analysis on the sentence "Please give me an answer", it is decomposed into five words, "Answer", "O", "O", "Wish", and "I will". And so on, two words “answer” and “wish” can be extracted. In the present embodiment, when the extracted word is classified as a noun, it is registered as the first word 902, and when it is classified as a verb, it is registered as the second word 904. Through the processing of the syntax analysis unit 700 described above (S208), it is possible to register in the character pattern table the words and phrases contained in the body of the email that was not determined to be necessary for reply by the sentence analysis unit and the reply judgment unit. To improve the vocabulary for In addition, in the character pattern table shown in FIG. 3, update date information may be added in the same manner as the text analysis information shown in FIG. For example, by updating the update date of the matched phrase in the processing in the sentence analysis unit, it is possible to consider a phrase that has not been updated after a predetermined period of time as an unnecessary phrase and delete it from the character pattern table Become. As a result, it is possible to prevent the character pattern table from continuing to increase due to the addition of words to the character pattern table by the syntax analysis unit.

  The above is the flow of processing when the mail transmitting / receiving apparatus transmits mail.

  Next, the contents of the display control process in the mail transmitting / receiving apparatus will be described with reference to FIG. FIG. 7 is a diagram showing a display content example of the received mail list in the mail transmitting / receiving apparatus. The display example shown in FIG. 7 includes a state 601, a sender 602, a subject 603, a reception date 604, and a reply necessity 605, and is displayed using sentence analysis information 800, a mailbox 1000, and mail management information 1100. Is created. The user of the mail transmitting / receiving apparatus can view the text of the selected mail by selecting the mail from the received mail list.

  Note that the display content of the status 601 is changed according to the status flag 1104 of the mail management information 1100 (a). In the display example shown in FIG. 7, the state 601 “unopened” for the state flag 114 “0”, the state 601 “opened” for the state flag 114 “1”, and the state for the state flag 114 “2”. 601 “Reply completed” is displayed.

  Further, the display content of the reply necessity 605 is created using the analysis accuracy 802 of the sentence analysis information 800 and the reply determination flag 1105 of the mail management information 1100 (a). In the example shown in FIG. 7, a reply necessity flag 605 “required” is required for the reply determination flag 1105 “1” of the mail management information 1100 (a), and a reply necessity flag 605 “no” is determined for the reply determination flag 1105 “0”. Is displayed. Further, in the example shown in FIG. 7, in addition to the notation “necessary” or “no”, the first word and the second word in the character pattern table 900 detected in the analysis process (S102) for the received mail The average of the analysis accuracy 802 of the combination is displayed. In the above-described process of calculating the average of analysis accuracy, the same process as the calculation process in the reply necessity determination in the reply determination unit 300 is performed. For example, the display contents of the received mail specified by the mail number “R0001” are the combination numbers 1106-1 “001-02” “002-03” “004-02” as the combination information 1106 of the mail management information 1100 (a). "Is registered. The analysis accuracy for these combination numbers is the analysis accuracy “99” for the combination number “001-02”, the analysis accuracy “68” for the combination number “002-03” in the analysis accuracy 802 of the sentence analysis information 800, The analysis accuracy “4” is registered for the combination number “004-02”, and the average analysis accuracy “84” is calculated by performing the same processing as the calculation processing in the reply determination unit 300 in the reply determination unit 300. obtain. Therefore, in the display content example of the received mail list shown in FIG. 7, “required (84)” is displayed as the display necessity of the reply necessity 605 for the mail number “R0001”.

  Further, in the display content example of the received mail list shown in FIG. 7, the reply necessity 605 of the mail number “R0002” is displayed as “No (4)”. This is a combination of the first word and the second word in the character pattern table specified by the combination number “004-02” in the sentence analysis processing for the mail body of the received mail specified by the mail number “R0002”. Is shown in the mail text, but since the analysis accuracy is “4”, the reply determination unit 300 determines “No” in the reply necessity determination.

  Further, in the display content example of the received mail list shown in FIG. 7, the reply necessity 605 of the mail number “R0003” is displayed as “necessary (69)”. This indicates that the analysis accuracy of the necessity determination of reply to the received mail specified by the mail number “R0003” is “69”, indicating a “necessary” determination with relatively high analysis accuracy, but the status of the received mail Shows an example in which remains “unopened”.

  In the above list display example, the user of the mail transmission / reception apparatus selects a reply in the status 601 “unopened” and selects whether the reply necessity 605 is “required”, so that the reply determination unit 300 replies. It becomes possible to preferentially check the received mail determined to be important. Further, among the cases where the status 601 is “unopened”, and there are a large number of responses requiring / notifying 605 indicated as “necessary”, the reply determining unit 300 determines that the reply is necessary by arranging them in ascending order with analysis accuracy. Among the received mails, it is possible to select and check the ones with high accuracy of the necessity of reply.

  In the example of display contents of the received mail list shown in FIG. 7, the display contents of the necessity / unnecessity of reply 605 may be replaced with the characters “necessary” and “no” as icon images. At this time, the display content of the icon image may be changed in accordance with the numerical value of the analysis accuracy, so that the analysis accuracy of the determination as to whether or not the answer is necessary may be distinguished and displayed. The same applies to the display contents of the state 601.

  The above is the flow of the display control process in the mail transmitting / receiving apparatus.

  Next, the flow of the reminding process in the mail transmitting / receiving apparatus will be described with reference to FIG. FIG. 9 is a flowchart showing the flow of the dunning process of the mail transmitting / receiving apparatus. The reminder processing of the mail transmitting / receiving device is performed, for example, when the mail transmitting / receiving device is started, and a reply determination is required and the received date of the unanswered mail is compared with the system date, and a certain period has elapsed. The user is notified of a reminder message prompting a reply. Other triggers for starting the dunning process may be configured to be executed at predetermined time intervals.

  First, the mail transmission / reception apparatus uses the reply prompting unit 500 to extract mail management information in which the reply determination flag 1105 is “1” and the status flag 1104 is “0” or “1” (S301).

Next, the reply requesting unit 500 of the mail transmitting / receiving apparatus compares the received date 1102 of the extracted mail management information with the system date, and extracts those that have passed a certain period of time (S302). Furthermore, the e-mail management information for which the period has passed is set as a dunning object, and when one or more dunning objects exist (YES in S303), a dunning message that prompts a reply to the dunning mail is displayed (S304). . FIG. 10 is a diagram showing an example of the display content of the dunning message. In the example shown in FIG. 10, an email with the subject “minutes” sent from the sender “CCC” is received on “20004/02/10”, and the necessity of answer is determined as “necessary (69)”. However, it is notified that the state is “unopened” even if three days or more have elapsed from the date of reception. By displaying this reminder message, it is possible to prevent omission of replies to e-mails determined to be necessary for reply by the reply determination unit 300.
(Additional remark 1) The following additional remark 1 is disclosed regarding embodiment including the said Example 1. FIG.
