Description

  The present invention relates to a mail priority determination device that determines mail priority. More particularly, the present invention relates to a mail priority determination device that determines the priority of mail within a predetermined organization.

  Today, email is used as an important tool for communication. In particular, when mail is used in business, many mails are sent and received in one day, and it may take a long time for the user to view or reply to many mails. However, it is rare that all emails have the same importance to the user, and the user preferentially processes emails that seem important, and browses emails that seem to be less important later. I am trying to improve the efficiency of my work.

In the conventional mail system, a flag indicating the priority at the time of transmission is set by the sender on the sender terminal side, and the priority is specified on the receiver terminal, or the receiver individually indicates the mail priority. Was set manually. In such a case, the recognition of priority is not necessarily the same between the sender and the receiver, and if the priority is low for the receiver even if the priority is clearly indicated on the sender side, A person does not always view or reply to the mail with priority. In addition, it takes time for the receiver to manually set the flag.

  The control unit 14 is configured by a CPU or the like, and controls the execution of each process of the mail priority determination device 10. The control unit 14 may realize the function by reading a program for realizing the function of each of the following units from the storage unit 11 and executing the program, or may be realized by dedicated hardware. It may be a thing.

  The control unit 14 includes an accepting unit 141 that receives mail and various information transmitted from the user terminal 30, an input field adding unit 142 as an input field adding unit, a keyword extracting unit 143 as a keyword extracting unit, and a counting unit. A totaling unit 144, a priority determination unit 145 as a priority determination unit, and a transmission unit 146.

  The receiving unit 141 receives mail transmitted from the user terminal 30, and also receives information input in the evaluation input field and stores it in the other person evaluation rank DB 114 as input information receiving means. In addition, when the priority is uniquely set on the user terminal 30, the reception unit 141 receives information on the individual priority and stores it in the individual setting rank DB 113. Moreover, the reception part 141 receives reception time and opening information from the user terminal 30 as an opening information reception means, and memorize | stores it in opening time total information DB115.

  The input field adding unit 142 adds information for adding an evaluation input field for the recipient to input an evaluation for the mail (sent mail) received by the receiving unit 141. Using the information added by the input field adding unit 142, the mailer 31 of the user terminal 30 displays the evaluation input field 61 on the received mail. Here, a display example of the received mail 60 to which the evaluation input field 61 is added will be described with reference to FIG. FIG. 10 is a display example of the received mail 60 to which the evaluation input field 61 is added.

  The received mail 60 shown in FIG. 10 is an example of a mail in which an evaluation input field 61 is added to the mail received from the sender's user terminal 30 with the receiving unit 141.

  In the evaluation input column 61, buttons 62a, 62b, and 62c are provided. Buttons 62a, 62b, and 62c are each associated with a priority rank. The receiver evaluates the sender and selects the buttons 62a, 62b, and 62c having the corresponding rank. Then, in response to selection of the buttons 62a, 62b, and 62c, the mailer 31 transmits the priority rank information corresponding to the selected buttons 62a, 62b, and 62c to the mail priority determination device 10 as evaluation information. To do.

  Returning to FIG. 1, the keyword extraction unit 143 analyzes the mail (sent mail) received by the reception unit 141 and extracts keywords included in the text or the like. The keywords included in the email are keywords stored in the common / business keyword table 52 in FIG. 3, and the keyword extraction unit 143 extracts both the business keyword and the common keyword. To extract a keyword, for example, an existing technique such as a character component table method or morphological analysis can be used.

  The totaling unit 144 totals information related to the priority rank of the emails determined based on each evaluation item. Specifically, the counting unit 144 counts the number of keywords extracted by the keyword extracting unit 143 or calculates an average opening time, and as a result, priority based on the priority rank determined in each evaluation item. Count the degree points.

First, a case where the counting unit 144 counts priority points based on keywords included in an email will be described.
As described above, the keyword extraction unit 143 first extracts keywords (business keywords and common keywords) from the transmitted mail. The totaling unit 144 refers to the common / business keyword DB 112 and obtains priority rank information associated with each extracted keyword. Then, the totaling unit 144 refers to the point information DB 117, obtains priority points for each priority rank, totals the priority points for all keywords extracted from the mail, and calculates a total value.

Next, the case where the totaling unit 144 totals priority points with reference to the other person evaluation rank DB 114 will be described.
The totaling unit 144 searches the user ID of the sender of the transmission mail received by the reception unit 141 with reference to the other person evaluation rank DB 114. And the information of "evaluation number" for every priority rank linked | related with the said user ID is acquired. The totaling unit 144 acquires priority points for each priority rank from the point information DB 117, and calculates priority points for each priority rank according to the priority rank and the number of evaluations in the other person evaluation rank DB 114. . Then, the aggregation unit 144 calculates the sum of priority points in all priority ranks.

  For example, according to the other person evaluation rank table 54 (FIG. 5), for the user ID “12345”, one person evaluated as the priority rank “A” and four persons evaluated as the priority rank “B”. The number of persons evaluated as the priority rank “C” is six. Further, according to the point table 57 (FIG. 8), the priority rank “A” has three priority points, the priority rank “B” has two priority points, and the priority rank “C” has a priority. The point is one point. Therefore, the totaling unit 144 applies these points, and the total of the priority rank “A” is 3 points, the total of the priority rank “B” is 8 points, and the total of the priority rank “C” is 6 points. And the sum of all priority points is calculated as 17 points.

Next, a case will be described in which the counting unit 144 calculates priority ranks based on the average opening time of mails to obtain priority points.
First, the counting unit 144 determines whether or not the number of acquisitions of the unsealed information received by the receiving unit 141 has reached a predetermined ratio with respect to the total number of recipients for mails that are simultaneously transmitted to a plurality of recipients. When the number of opening information acquisition reaches a predetermined ratio, the counting unit 144 calculates an average opening time of the opening information acquired so far. Then, the counting unit 144 refers to the point information DB 117 and determines whether the calculated average opening time is included in any of the time ranges of the average opening time in the point table 57. The totaling unit 144 acquires priority rank information associated with the time range included in the calculated average opening time, and stores it in the average opening time rank DB 116.

  For example, according to the opening time count information table 55 of FIG. 6, it is assumed that a person with a user ID of 12345 has simultaneously sent a mail “aaa” to 10 persons. Among them, since six users received the mail aaa and further opened it, the reception time and opening time for each opened user are stored. The totaling unit 144 calculates the average opening time based on the information by the six users because the number of opening information acquisition persons with respect to the total number of recipients has reached a predetermined ratio. According to the average opening time rank table 56 of FIG. 7, the average opening time of the mail aaa is 1 hour 10 minutes 9 seconds. Next, the totaling unit 144 obtains a priority rank from the time range in which the average opening time is included. The counting unit 144 stores the priority rank obtained in the average opening time rank table 56 from the point table 57 of the point information DB 117, assuming that the priority rank of the average opening time is “B”, and corresponding priority. The degree points are temporarily stored in the storage unit 11.

  Returning to FIG. 1, the priority determination unit 145 determines an overall priority rank (hereinafter referred to as an overall priority rank) for the outgoing mail received by the reception unit 141. The priority determination unit 145 obtains information on priority points collected by the aggregation unit 144 for each evaluation item, and calculates the sum of all priority points. The priority determination unit 145 refers to the priority determination criterion information DB 118 and determines the overall priority rank from the calculated total value of priority points. Specifically, the priority determination unit 145 determines whether the calculated total value of the priority points is included in any of the numerical ranges defined in the “total points” item of the general priority determination criterion table 58. . And the priority determination part 145 determines with the total priority rank linked | related with the numerical value range where the total value of a priority point is included being the total priority rank of the said transmission mail.

  Also, the priority determination unit 145 refers to the individual setting rank DB 113 to determine whether or not a priority rank is individually set for the sender among the recipients of the transmission mail. When the receiver sets the priority rank individually for the sender, the priority determination unit 145 compares the set priority rank with the overall priority rank. As a result of the comparison, when the individually set priority rank is higher than the overall priority rank, the priority determination unit 145 gives priority to the individually set priority rank and determines the final priority rank. Judge that there is.

  The transmission unit 146 adds the priority rank information determined by the priority determination unit 145 to the transmission mail received by the reception unit 141, and transmits it to the user terminal 30 used by the recipient of the transmission mail.

  With reference to FIGS. 11 to 15, processing in which the mail priority determination device 10 determines the priority rank of outgoing mail will be described. 11 and 12 are flowcharts in which the mail priority determination device 10 determines the priority rank of the outgoing mail.

  In step S <b> 11, the reception unit 141 of the control unit 14 determines whether or not a transmission mail or other information has been received. If the reception unit 141 receives a transmission mail or other information (YES in step S11), the reception unit 141 moves the process to step S12. If the reception unit 141 does not receive the transmitted mail or other information (NO in step S11), the reception unit 141 ends this process.

  In step S12, the reception unit 141 causes the storage unit 11 to store other information received together with the outgoing mail. The other information is, for example, priority rank information individually set by the user, evaluation information selected in the evaluation input field 61, or the like. Specifically, when receiving information on the priority ranks individually set by the user, the receiving unit 141 stores the information in the individual setting rank DB 113, and when receiving the evaluation information, the receiving unit 141 stores the information. Stored in the person evaluation rank DB 114.

  In step S13, the reception unit 141 of the control unit 14 determines whether or not the transmission mail is transmitted to a plurality of users at the same time. Specifically, the reception unit 141 determines whether or not a plurality of users are registered at the destination, and whether or not the group address is transmitted to a plurality of users with one mail address. If the reception unit 141 determines that the transmission mail is transmitted to a plurality of users (YES in step S13), the reception unit 141 moves the process to step S14. If the reception unit 141 determines that the transmission mail is not transmitted to a plurality of users (NO in step S13), the reception unit 141 moves the process to step S15.

  In step S14, the input field adding unit 142 of the control unit 14 adds the evaluation input field 61 (FIG. 10) to the outgoing mail.

  In step S15, the control unit 14 (the keyword extraction unit 143 and the totaling unit 144) performs a priority point totaling process using keywords. Details will be described later. When this process ends, the control unit 14 moves the process to step S16.

  In step S <b> 16, the totaling unit 144 of the control unit 14 totals priority points based on the evaluation in the evaluation input field 61. Details will be described later. When this process ends, the control unit 14 moves the process to step S17.

  In step S17, the priority determination unit 145 of the control unit 14 determines the overall priority rank. Specifically, the priority determination unit 145 adds up the priority points for each evaluation item totaled by the totaling unit 144 and determines the general priority rank based on the general priority determination criterion table 58.

  In step S18, the priority determination unit 145 determines whether a priority rank is individually set for the sender among the recipients of the transmission mail. The priority determination unit 145 refers to the individual setting rank DB 113 and determines whether there is information in which the priority rank is set in the individual setting rank table 53. The priority determination unit 145 moves the process to step S19 when there is information in which the priority rank is set in the individual setting rank table 53 (YES in step S18). If there is no information for setting the priority rank in the individual setting rank table 53 (NO in step S18), the priority determination unit 145 moves the process to step S23 in FIG.

  In step S <b> 19, the priority determination unit 145 acquires information for setting the priority rank from the individual setting rank table 53. Then, the priority determination unit 145 compares the individually set priority rank and the general priority rank (step S20 in FIG. 12). As a result of the comparison, the priority determination unit 145 moves the process to step S21 when the individually set priority rank is higher than the general priority rank (YES in step S20). Moreover, the priority determination part 145 moves a process to step S22, when the priority rank set separately is not a rank larger than a comprehensive priority rank (in the case of NO at step S20).

  In step S21, the priority determination unit 145 determines to prioritize the individually set priority rank over the general priority rank determined in step S17. For this reason, the individually set priority rank is the priority rank that is finally displayed on the user terminal 30 of the recipient.

  In step S22, the priority determination unit 145 determines that the overall priority rank determined in step S17 is prioritized over the individually set priority ranks. For this reason, the overall priority rank is the priority rank that is finally displayed on the user terminal 30 of the recipient.

  In step S23, the transmission unit 146 of the control unit 14 adds the priority rank information determined in step S20 or step S21 to the transmission mail and transmits it to the recipient. That is, the outgoing mail includes priority rank information.

Here, a display example on the user terminal 30 of the recipient will be described. FIG. 13 is a display example of the mailer 31 on the user terminal 30 of the recipient.
The display window 70 of the mailer 31 displays a mail folder 71 and a received mail list 72. The received mail list 72 includes a rank field 73, a sender field 74, a subject field 75, and a reception date / time field 76. The rank column 73 displays the priority rank determined by the priority determination unit 145.

  With reference to FIG. 14, the priority point aggregation processing by keywords will be described. FIG. 14 is a flowchart showing a priority point aggregation process using keywords.

  In step S31, the keyword extraction unit 143 of the control unit 14 extracts keywords from the transmitted mail. Specifically, the keyword extraction unit 143 refers to the common / business keyword DB 112 and extracts the keywords registered in the common / business keyword table 52 from the transmitted mail.

  In step S32, the totalization unit 144 of the control unit 14 obtains priority points for the keywords extracted by the keyword extraction unit 143, and calculates the total value thereof. Then, the totaling unit temporarily stores the calculated total value of the priority points in the storage unit 11 (step S33).

  With reference to FIG. 15, the priority point totaling process by the evaluation input column 61 will be described. FIG. 15 is a flowchart showing the priority point counting process performed by the evaluation input field 61.

  In step S41, the totaling unit 144 of the control unit 14 refers to the other person evaluation rank DB 114 and searches for the user ID of the sender of the outgoing mail received by the receiving unit 141. Then, the totaling unit 144 acquires “evaluation number” information for each priority rank associated with the user ID, and the priority rank and evaluation number in the other person evaluation rank table 54 for each priority rank. A priority point is calculated (step S42).

  In step S43, the counting unit 144 calculates the total value of priority points in all priority ranks. Then, the totaling unit 144 temporarily stores the calculated total value in the storage unit 11 (step S44).

With reference to FIG. 16, the priority point aggregation processing based on the average opening time will be described. FIG. 16 is a flowchart showing the priority point counting process based on the average opening time.
This process is a process performed separately from the processes in FIGS. 11 and 12.

  In step S <b> 51, the reception unit 141 of the control unit 14 receives the opening information from the user terminal 30 of the recipient of the mail transmitted to a plurality of people at the same time, and stores the received opening information in the opening time aggregation information DB 115.

  In step S52, the reception unit 141 of the control unit 14 determines whether or not the ratio between the counter value and the number of simultaneous recipients of the transmission mail has reached a predetermined ratio. When the ratio between the counter value and the number of simultaneous recipients reaches a predetermined ratio (YES in step S52), the reception unit 141 ends the process of this flowchart. If the ratio between the counter value and the number of simultaneous recipients does not reach the predetermined ratio (NO in step S52), the reception unit 141 moves the process to step S53.

  In step S53, the reception unit 141 adds 1 to a counter that counts opening information. This counter is stored in a predetermined area of the storage unit 11.

  In step S54, the reception unit 141 determines whether or not the ratio between the counter value and the number of simultaneous recipients of the transmission mail has reached a predetermined ratio. If the ratio between the counter value and the number of simultaneous recipients reaches a predetermined ratio (YES in step S54), the reception unit 141 moves the process to step S55. The reception unit 141 ends the process when the ratio between the counter value and the number of simultaneous recipients does not reach the predetermined ratio (NO in step S54).

  In step S55, the counting unit 144 calculates an average opening time based on the reception time and opening time of the opening information received so far. And the total part 144 determines a priority rank based on the calculated average opening time with reference to the point table 57, and acquires the information of a priority point (step S56).

  In step S57, the totalization unit 144 transmits the acquired priority rank information to the user terminals 30 of all recipients. The mailer 31 of the user terminal 30 rewrites the priority rank of the corresponding mail to the received priority rank in response to receiving the priority rank information.

  In step S <b> 58, the totaling unit 144 stores the acquired priority rank information in the average opening time rank DB 116 and temporarily stores the priority point information in the storage unit 11. Further, the counting unit 144 clears the counter (step S59).

  According to the present embodiment, the mail priority determination device 10 stores the business assignment information DB 111 that stores business assignment information, the words included therein as business keywords, and the words different from the business keywords as common keywords. The common / business keyword DB 112 is provided. In addition, the mail priority determination device 10 includes a totaling unit 144 and a priority determination unit 145 that determine a mail priority rank based on keywords included in the mail. Thereby, the mail priority determination apparatus 10 can determine the mail priority rank from the contents of the mail. Then, the user can recognize which mail is an important mail without performing individual settings.

  In addition, according to the present embodiment, the mail priority determination device 10 includes the input field adding unit 142 that adds the evaluation input field 61 to the transmitted mail. Further, the counting unit 144 and the priority determination unit 145 of the mail priority determination device 10 determine the priority rank for the sender based on the evaluation by the evaluation input field 61. Thereby, the mail priority determination apparatus 10 can determine the priority rank for every sender based on the relative evaluation by the user.

  Further, according to the present embodiment, the mail priority determination device 10 totals the average opening time for mails simultaneously transmitted to a plurality of people, and the totaling unit 144 that determines the priority rank based on the average opening time and the priority A degree determination unit 145 is provided. The transmission unit 146 transmits the determined priority rank to the user terminal 30 used by the receiver. Thereby, since there is a high possibility that an email with an average open time is an important email, the priority rank of the email can be shown to a user who has not opened yet.

  Further, according to the present embodiment, the mail priority determination device 10 includes the individual setting rank DB 113 that stores the priority rank uniquely set in the user terminal 30, and the priority determination unit 145 is individually set. The priority rank and the general priority rank are compared, and if the individual priority rank is equal to or higher than the general priority rank, the individual priority rank is given priority. Thereby, each user's intention can be reflected in determination of the priority rank of mail.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.

  In the above-described embodiment, the sent mail is evaluated by the keyword, the evaluation by the evaluation input column 61, and the average opening time, respectively, and the total priority rank is determined by the sum of the priority points in each evaluation item. Not limited to this. For example, the priority rank may be determined using only some of these evaluation items. Further, the priority points of each evaluation item may be calculated by weighting.

  In the above-described embodiment, the priority ranks individually set by the user are prioritized. However, the priority rank is not limited to this, and the priority points of the priority ranks set individually are added to the total priority points calculated in step S17 in FIG. May be added.

  The priority point and the priority rank in the above-described embodiment can be appropriately changed as necessary by the administrator of the mail priority determination device 10. For example, in this embodiment, the priority rank is set to three levels, but it may be more than this. The same applies to priority point values and numerical ranges.
