131 stores the community ID 112 of the community estimated to be related.

The public flag 133 indicates whether or not the target private mail is shared among the members of the community estimated to be related. The initial value of the public flag 133 is false (not shared), and is edited by the public flag editing unit 9. One private mail can have a relationship with a plurality of communities.

FIG. 5 is an example of the community information table 140 stored in the community information storage unit 14.

As shown in FIG. 5, the community information table 140 includes a community ID 141 that is a community identifier, a community address 412, a community name 143, a community overview 144, a member email address 145, and a private email search condition 14.
It has 6 items.

Here, an example of an operation when the information sharing system 100 receives mail via the access control unit 3 will be described with reference to FIGS. 6 to 7.

First, the mail receiving unit 4 of the information sharing system 100 receives a mail (step S10).
And the mail type determination unit 5 analyzes the destination of the received mail (step S11).

The mail type determination unit 5 refers to the community information stored in the community information storage unit 14 and determines whether the existing community address is included in the TO destination or the CC destination among the destinations of the received mail (step) S12). That is, it is determined whether the destination of the received mail matches the community address 142 stored in the community information storage unit 14, and it is determined whether the mail type is a private mail or a community mail.

When the address of a specific community is included in the TO destination or the CC destination (Yes in step S12), the mail type determination unit 5 determines that the mail is a community mail and stores the mail in the community mail storage unit 11. (Step S16). Thereby, the mail type determination unit 5 ends the process.

If the TO address or CC address does not contain a specific community address (No in step S12), the mail type determination unit 5 determines that the mail is a private mail and stores the mail in the private mail storage unit 12. (Step S13).

In the information sharing system 100, when a private mail is transmitted from the user terminal 2, an information sharing system address set in advance as a BCC destination may be input and transmitted. In this case, the mail type determination unit 5 can determine the mail type depending on whether the address of the information sharing system is included in the BCC destination.

When the mail is stored in the private mail storage unit 12, the mail type determination unit 5 acquires community information registered in the community information storage unit 10 (step S14). Specifically, the mail type determination unit 5 searches the community information storage unit 10 and stores the TO address 122 and CC address 1 of the private mail information stored in the private mail storage unit 12.
23 or the sender 124 acquires community information included in the member 115 of the community information.

The related community estimation unit 7 performs a related community estimation process for estimating a community related to the mail stored in the private mail storage unit 12 based on the community information acquired by the mail type determination unit 5 (step S15). . That is, the related community estimation unit 7 estimates whether the stored private mail is related to a specific community. After the related community estimation process ends, the information sharing system 100 ends the operation.

Here, with reference to FIG. 7, the related community estimation process by the related community estimation part 7 in step S15 of FIG. 6 is demonstrated.

First, the related community estimation unit 7 receives the community information acquired by the mail type determination unit 5 (step S151). When the mail search period set in the private mail search condition 116 included in the received community information includes the posting date 125 of the private mail stored in the private mail storage unit 12 (Yes in step S152). The related community estimation unit 7 analyzes the contents of this private mail and estimates whether there is a relationship with a specific community.

Specifically, the related community estimation unit 7 performs natural language processing on the title 136 and the body 137 of the private mail and analyzes them (step S153). Subsequently, the related community estimation unit 7 reads the community name 113 and the outline 1 included in the extracted community information.
14 is subjected to natural language processing and analyzed (step S154).

The related community estimation unit 7 estimates the degree of association between the private mail and the community based on the analysis result of the private mail and the analysis result of the community information (step S155). When it is estimated that there is a relationship with private mail (step S15)
6 is Yes), the message ID 121 of the private mail and the community ID 111 of the community information are stored in the related community table 130 (step S157),
The related community estimation process is terminated.

That is, in step S153 and step S154, the related community estimation unit 7 includes the characteristics of the topic of the private mail based on the contents of the mail text and the title,
The feature of each community topic based on the community name 113 and the community outline 114 is analyzed. In step S155 and step S156, the related community estimation unit 7 determines the similarity between the topic features of the private mail and the community based on the analysis result.

The topic is a set of representative words in a certain sentence set. In this example, the topic is a set of representative words in a private mail or a plurality of community mails belonging to a community. The feature of the topic is a set of words that are used frequently in typical sentences among the typical words. In this case, the similarity of the topic features is indicated by a value obtained by calculating the inner product by regarding a set of these words as a vector.

Specifically, in step S153, the related community estimation unit 7 acquires a set of community representative words. That is, the related community estimation unit 7 includes a community name 113, a community outline 114, a text 117 of the community mail,
Morphological analysis is performed on the private mail title 136 and text 137 stored so far, and phrases such as nouns, verbs, and unknown words are extracted. It should be noted that the body of the email may not be the whole but only the first half where the summary of the contents is written.

The related community estimation unit 7 sets, for the extracted words and phrases, a set of words characterizing a community period or a certain number of community mails from the title, outline, and analysis point of each community.
n is the TFIDF method (term frequency-inverse document)
(t frequency method).

Further, the characteristic Y of the word characterizing the title and the body of the private mail to be analyzed is also obtained by the TFIDF method.

Further, the inner product value of each X_n and Y is calculated as a similarity, and X_n having a value above a certain value is determined. Finally, the community corresponding to the corresponding X_n is regarded as a community having high similarity to the private mail to be analyzed, that is, a related community.

It should be noted that the mail search period set in the private mail search condition 116 included in the community information of the extraction result is not included in the private mail posting date 125 (No in step S152), or in step S155, the private mail If there is no community estimated to have a relationship with (No in step S156)
), The related community estimation unit 7 ends the process.

In this embodiment, the case of determining the relationship with the community for one private mail is taken as an example. For example, the relationship between the mail and the community is determined based on, for example, a plurality of mail exchanges. By doing so, it is possible to further narrow down the community to be related.

The determination of the relationship between the private mail and the community based on a plurality of mail exchanges is performed using, for example, a reply source message ID 118 included in the private mail information and indicating which mail is a reply. Alternatively, reference information (not shown) indicating which mail is being referred to may be used.

This makes it possible to associate the community with private mail with higher accuracy.

Referring to the flowchart of FIG. 8, when new community information is input from the user operation accepting unit 1 in the information sharing system 100, that is, the information sharing system 100.
An example of the operation when a new community is created will be described.

First, the community creation unit 10 receives community information (step S20). The community creation unit 10 stores the received community information in the community information storage unit 14 (step S21).

When community information is stored in the community information storage unit 14, the related community estimation unit 7 acquires a private mail stored in the private mail storage unit 12 (
Step S22). Similar to step S15 and FIG. 7 in FIG. 6, the related community estimation unit 7 estimates whether the private mail acquired in step S22 is related to the community stored in the community information storage unit 14 or not. Processing is performed (step S23).

Subsequently, the mail browsing unit 6 determines whether the user who creates the community includes the private mail included in the TO address 122, the CC address 123, or the sender 124 in the private mail acquired in Step S22 (Step S22). S24). In addition, when the user who browses the community is included in the TO address 122, CC address 123, or sender 124 of the private mail, this user is referred to as a related user of the private mail.

If the user creating the community has a private email that is a related user (
If step S24 is Yes), the mail browsing unit 6 presents the sharing candidate screen 170 for displaying these private mails to the user (step S25). An example of the sharing candidate screen 170 is shown in FIG.

As shown in FIG. 9, the share candidate mail screen 170 displays a community name 171, members 172 belonging to the community, a mail display area 173, and a determination button 179.

The mail display area 173 displays the mail title 174 and the sender 17 for each private mail for which the user who creates the community in step S24 is determined to be a related user.
5. Addressee 176, posting date and time 177, and check box 178 are displayed. The check box 178 is displayed for each mail and is in the off state in the initial state. The user checks the check box 178 of the mail to be shared in the created community among the displayed private mails, and turns it on.

The user checks the private mail checkbox 1 presented on the sharing candidate screen 170.
78 is edited, and it is determined whether or not each private mail is shared by members belonging to the created community (step S26). Specifically, the user clicks the check box 178 on the displayed sharing candidate screen 170 using the user operation accepting unit 1, and changes the check mark to on or off. When the check box 178 has been changed for all emails to be edited, the user uses the user operation accepting unit 1 to determine the decision button 179.
Click.

When the determination button 179 is clicked, the disclosure flag editing unit 9 displays the disclosure flag 133 of the related community table 130 based on the check box 178 of the sharing candidate screen 170.
Is updated (step S27). Thereby, the process in the case where a new community is created is completed.

If the user creating the community does not have a private email that is a related user (
In step S24 (Yes), the process when a new community is created is also completed.

With reference to FIG. 10, an example of the operation of the information sharing system 100 when the user browses a mail addressed to a community that has already been created will be described.

First, the user operates the user operation receiving unit 1 to input community information to be browsed into the mail browsing unit 6 (step S30). For example, assume that the user inputs a community address.

In addition, what a user inputs is not limited to a community address, but may be information that can identify a community to be browsed, such as a community ID and a community name.

The mail browsing part 6 extracts a community mail from the community mail table 110 based on the input community address (step S31).

Subsequently, the mail browsing unit 6 extracts the community ID 141 from the community information table 140 based on the input community address (step S32).

Community ID extracted by the email browsing unit 6 by the private email extraction unit 8
Based on 141, related community information is extracted from the related community memory | storage part 13 (step S33). The private mail extraction unit 8 extracts a private mail from the private mail table 120 based on the message ID 132 included in the extracted related community information (step S34).

In the extracted private mail, the private mail extracting unit 8 allows the user browsing the information community to use the TO address 122, the CC address 123, or the sender 124.
It is determined whether there is a private mail included in (step S35).

When any of the TO address 122, CC address 123, and sender 124 of the extracted private mail information includes the user's mail address input in step S30 (Yes in step S35), that is, the private mail extraction unit 8 When it is determined that the user browsing the community is a related user, the mail browsing unit 6 displays a list of private mails extracted by the private mail extracting unit 8 as in step S25 of FIG. A screen 170 is presented to the user (step S36). At this time, the check on / off of the check box 178 is displayed based on the disclosure flag 133 of the related community table 130.

The user inputs whether or not each mail is shared within the community via the sharing candidate screen 170, and the public flag editing unit 9 creates each private mail based on the user's input. The public flag 133 indicating whether or not to share is edited (step S37).

The mail browsing unit 6 uses the community mail extracted in step S31 and step S37.
The user is presented with a community browsing screen 160 that displays the private mail that has been determined to be shared at step S38.

At this time, the disclosure flag editing unit 9 may update the disclosure flag 133 of the related community table 130 based on the check box 178 of the sharing candidate screen 170 as in step S27 of FIG.

FIG. 11 shows an example of the community browsing screen 160 presented to the user by the mail browsing unit 6 in step S38 of FIG.

The community browsing screen 160 shown in FIG. 11 displays a community name 161, community members 162, and a mail display area 163.

The community name 161 and community members are displayed based on the community information extracted in step S33 of FIG.

The mail display area 163 displays community mails and private mails extracted by the private mail extraction unit 8 in the community browsing process, and includes items of a mail title 164, a sender 165, and a posting date 166.

Returning to the description of FIG. When none of the TO address 122, CC address 123, and sender 124 of the extracted private mail includes the user's mail address input in step S30 (No in step S35), the mail browsing unit 6 supports private mail. The public flag 133 of the related community table 130 obtained is acquired (step S
40).

If “true” exists in the acquired public flag 133 (Yes in step S39), the mail browsing unit 6 displays the community mail that is the extraction result in step S31 and the private mail whose public flag 133 is true. Community browsing screen 16
0 is presented to the user (step S40).

When “true” does not exist in the obtained public flag 133 (step S39)
No), the mail browsing unit 6 presents to the user a community browsing screen 160 that displays the community mail extracted in step S31 (step S41).

In step S38 and step S40, the mail browsing unit 6 may add a mark such as “P mark (private mark)” to the private mail presented to the user. As a result, the user can distinguish between mail shared by all community members and mail that is related to the community but not yet shared by all members. That is, when a related user browses a community, private mail can be shared only with related users in the community with a simple operation.

As described above, the information sharing system 100 according to the present embodiment stores a private mail, which is a mail that does not yet belong to the community, in the system. As a result, it is possible to store in the system mail that may be shared with the community in the future.

Therefore, even if a message is exchanged between individuals when an appropriate community has not been created, it can be shared among members of the community when a community related to the message is created.

Furthermore, according to the information sharing system 100 of the present embodiment, when browsing community emails, out of private emails stored as described above, emails related to a specific community are extracted and displayed to the user. Information that is not registered in the community can be shared with a simple operation without any work such as registration processing by an importer. Therefore, it is possible to avoid an improvement in information sharing and a decrease in work efficiency due to a user performing a registration work.

Further, the information sharing system 100 can edit the public flag 133 related to the community and set whether or not to share the private mail related to the community. In other words, according to the information sharing system 100 of the present embodiment, it is possible to share only with related users (from or to whom the private mail is sent) without being shared within the community that does not want to be shared among private mails related to the community. It becomes.

The information sharing system 100 extracts private mail related to the community and displays it to the user, and the user edits the public flag of the displayed private mail. This facilitates the determination of whether or not the user should share private mail with the community.

As mentioned above, although embodiment of this invention was described, this embodiment was shown as an example to the last and is not intending limiting the range of invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
