  Hereinafter, a web mail system disclosed as one embodiment of the present invention will be described.

  FIG. 1 is a diagram illustrating a configuration example of a web mail system according to an embodiment.

  The web mail system (server) 1 is capable of data communication with the user terminal (client) 2 via the network N, receives web mail addressed to the client's mail account, and receives received web mail (hereinafter simply referred to as received mail). And a list and contents of received mails are displayed on the user terminal 2 as a client.

  The web mail system 1 includes a received mail display device 10 that displays received mail on the user terminal 2 and a received mail storage device 11 that stores received mail for each user account.

  The received mail display device 10 includes a classification information storage unit 13, a received mail classification unit 15, and a list display unit 17.

  The classification information storage unit 13 stores classification information related to classification based on the sender (source email address), subject, or content of the received mail. The received mail classification unit 15 is processing means for classifying received mail. The list display unit 17 generates a display screen for displaying a list of received mails based on the classification information.

  The user terminal 2 includes a received mail display program 21.

  The received mail display program 21 accesses the web mail system 1 and displays a display screen showing received mail addressed to the user account.

  FIG. 2 is a diagram illustrating a processing flow example of received mail classification processing of the web mail system 1 according to an embodiment.

  The web mail reception and storage process of the web mail system 1 is a known process, and thus the description thereof is omitted. The received mail classification unit 15 of the received mail display device 10 performs the following steps S1 to S5.

  Step S1: The received mail classification unit 15 extracts the received mail for each user account (mail address) from the received mail storage device 11, and generates a record for the received mail in the classification information storage unit 13 (classification information table).

  If the classification information table is already stored, a record for the received mail received after the previous process is added, and the deleted record for the received mail is deleted.

  Step S2: The received mail classification unit 15 classifies the received mail based on the source mail address set in the mail header of the extracted received mail, and assigns a 4-digit classification number to each classification based on the source mail address. Assigned and recorded in the classification information table 13 (first classification).

  FIG. 3 is a diagram illustrating an example of classification (first classification) based on a source mail address of a received mail.

  The left side of FIG. 3 shows each source mail address of the user's received mail.

  The received mail classification unit 15 classifies the received mail group by the source mail address, and generates three classifications shown on the right side of FIG. The received mail classification unit 15 assigns the classification number 0001 to the group of received mail whose source mail address is “aaa@jp.fffff.com”, and the classification number 0002 to the group whose name is “bbb@jp.fffff.com”. , A classification number 0003 is assigned to each group “ccc@jp.fffff.com”.

  Step S3: The received mail classification unit 15 extracts a character string of the subject (title) set in the mail header of the received mail for each group of the received mail classified in the process of Step S2, and the character string of the subject Are grouped together with a predetermined ratio including a complete match, and a 4-digit classification number is assigned to each group of received mails and recorded in the classification information table 13 (second classification).

  More specifically, the received mail classification unit 15 takes out the character string of the subject of one received mail in the group according to the first classification, and the character strings of the subject match at a predetermined ratio or more (for example, 50% or more). All other received mails are extracted, and the extracted received mails are classified into one group. In addition, the process which collates character strings and determines the complete match or the partial match more than a predetermined ratio applies the known process method.

  The received mail classification unit 15 sets in advance a character or character string to be excluded from the determination target character string (exclusion target character string) before matching the subject, and excludes the character string to be excluded from the extracted character string of the subject. You may collate using the character string which deleted. The exclusion target character string is, for example, a character string such as “Re:”, “RE:”, “Res:”, “RES:”, “Fwd:”, “Fw:”, “FW:”, and the like.

  The character strings to be excluded may be individually set by setting instructions from the user terminal 2.

  FIG. 4 is a diagram showing an example of classification (second classification) based on the subject of the received mail.

  The left side of FIG. 4 shows each subject of the received mail group assigned the classification number 0003 (sender mail address “ccc@jp.fffff.com”).

  The received mail classification unit 15 deletes the character string corresponding to the character string to be excluded from the subject character string, collates the characters for the name combination of one received mail and the other received mail, It is calculated whether the ratio is a certain value (50%) or more.

  Here, the received mail classification unit 15 determines that the subject “Thank you” and “(Re :) Tired” are completely the same, and the subject “Thank you” is “Thank you” and “(Re :) It is determined that they match at a rate exceeding 50%.

  The received mail classification unit 15 classifies the three received mails with these subject names into one group and assigns a classification number 0001. Since the subject character strings of the other received mails shown on the left side of FIG. 4 do not match, one group is generated for each received mail, and a classification number is assigned to each group. For example, “Good morning” and “Good morning” in the subject lines are not determined to be partial matches because the percentage of matches in one subject is less than or equal to a predetermined value (50%). .

  The received mail classification unit 15 assigns classification numbers 0001, 0002, and 0003 to each group.

  Step S4: The received mail classification unit 15 collects received mails with similar received mail text (sentences) for each group classified in the process of step S3, and classifies each group classified by the collected text. A number is assigned and recorded in the classification information table 13 (third classification).

  The received mail classification unit 15 determines whether the texts of each combination of one received mail and other received mails are extracted based on any one or combination of the following conditions as conditions for determining the similarity of the texts. Determine if they are similar.

  Condition 1: The wording of the comparison target range extracted from the text is the same.

  The range to be compared is a part obtained by excluding the part that quotes the contents of the other text from the text. For example, a range or citation with a symbol (“>”, “| The range after the character string shown. In addition, as for the symbol which shows a quote sentence, you may make it set a character string separately by the setting instruction | indication from the user terminal 2 similarly to the character string to be excluded.

  Condition 2: The wording of the text matches at a preset ratio or more (for example, 50% or more).

  FIG. 5 is a diagram illustrating a classification example based on the text of the received mail.

  The left side of FIG. 5 shows the text of the received mail group of the group whose classification number of the first classification is 0003 and classification number 0001 of the second classification.

  When the received mail classification unit 15 performs the similarity determination based on the above condition 2, the received mail body texts whose subject lines are “Thank you” and “(Re :) Thank you” exceed the preset ratio. Therefore, they are judged to be similar. The received mail classification unit 15 classifies received mails with subject lines “Thank you” and “(Re :) Thank you” into one group, and assigns a classification number 0001. The received mail whose subject is “Thank you for your hard work” does not match more than a predetermined ratio, so it is classified into another group and given the classification number 0002.

  Step S5: The received mail classification unit 15 stores the classification number assigned in the processing of steps S2 to S4 in the classification information storage unit 13.

  FIG. 6 is a diagram illustrating an example of the classification information storage unit 13. The classification information storage unit 13 is implemented as a classification information table, and has data items such as sender, classification 1, classification 2, classification 3, date, time, subject, destination, copy destination, contents, and the like.

  “Sender” is the sender email address (from) of the received mail, “Date” is the received date of the received mail, “Time” is the received time of the received mail, “Subject” is the character string of the title of the received mail, “Destination” Is the destination mail address (to) of the received mail, “copy destination” is the destination mail address (cc) set as the copy destination, and “content” is the body text of the received mail. In these data items, corresponding information is extracted from the mail header of the received mail and recorded.

  “Category 1” is a classification number assigned by classification based on the sender mail address of the received mail, “Category 2” is a classification number assigned by classification based on the subject of the received mail, and “Category 3” is the text of the received mail Record the classification number assigned in the classification.

  Step S6: When the web mail system 1 receives the received mail display request from the received mail display program 21 of the client terminal 2, the list display unit 17 refers to the information related to the received mail addressed to the user account in the classification information table 13. A display screen for displaying a list (received mail list) arranged in order of received date and time is generated. The received mail display program 21 receives the generated display screen and displays it on the user terminal 2.

  In the received mail display device 10, the received mail classification unit 15 executes the processes of steps S <b> 1 to S <b> 5 for each preset period or every opportunity, but triggered by a received mail display request from the user terminal 2. You may make it perform the process of said step S1-S5, and produce | generate or update the classification | category information of the received mail of the requested user account.
