<Operation of information processing device>
The information processing apparatus 1 performs an operation of presenting the estimated document information and an operation of updating the prediction model, respectively. Hereinafter, the flow of each operation will be described with reference to a flow chart.

<Action to present the estimated document information>
FIG. 11 is a flow chart showing an example of an operation flow for presenting estimated document information. The processor 11 of the information processing device 1 determines whether or not an operation for searching a document from the terminal 2 via the communication line 3 has been accepted (step S101). While it is determined that the operation for searching this document is not accepted (step S101; NO), the processor 11 continues this determination.

On the other hand, when it is determined that the operation for searching the document has been accepted (step S101; YES), the processor 11 has registered the document in advance with the path of the document satisfying the conditions such as including the name of the document corresponding to the operation. It is extracted from the path DB 121 that is sometimes stored (step S102).

For example, when the information processing apparatus 1 stores the path DB 121 shown in FIG. 5 in the memory 12, when the processor 11 accepts an operation to search for a document including "document A" in the document name, the processor 11 receives the document ID. The paths corresponding to "D01", "D02", and "D03" are extracted from the path DB 121. This is because they all contain "Document A" in the path.

Then, among the documents stored in the extracted path, the document having the latest update date and time is specified (step S103), and the messages exchanged after the update date and time are acquired from the server device 6 (step S104).

When the processor 11 extracts the above-mentioned path, the one having the latest update date and time is "November 18, 13:05" of the document ID "D03". Therefore, the processor 11 identifies the document identified by the document ID "D03", and requests the server device 6 for a message exchanged after "November 18, 13:05", which is the update date and time. ..

FIG. 12 is a diagram showing an example of a message exchanged between users. In the example shown in FIG. 12, the server device 6 provides a message service for exchanging conversations between users. For example, the message "Please correct the XX part of Document A" shown in FIG. 12 was sent by the user identified by the user ID "U11" at 15:34 on November 18. Is. Then, the user identified by the user ID "U12" for this message "OK" at 15:40 on November 18, as shown in FIG. 12, correct the document A and send it to the client. I will wake up. "

Both of the two messages shown in FIG. 12 are transmitted after the above-mentioned "November 18, 13:05". Therefore, the processor 11 acquires these two messages from the server device 6.

The processor 11 extracts the messages referring to the document indicated by the above-mentioned operation from the messages acquired in step S104 (step S105), and analyzes those messages by the prediction model 124 (step S106).

Both of the two messages shown in FIG. 12 include the character string "Document A". That is, these two messages refer to Document A. The processor 11 analyzes these messages by the prediction model 124. When the prediction model 124 refers to the document to be searched with, for example, the words "update" and "correction", the possibility that the document has been updated is highly evaluated.

As a result of the analysis, the processor 11 determines whether or not the document to be searched may have been updated after the above-mentioned update date and time (step S107). When it is determined that the above-mentioned document may not have been updated (step S107; NO), the processor 11 ends the process. On the other hand, when it is determined that the above-mentioned document may have been updated (step S107; YES), the processor 11 controls the terminal 2 to present the information of this document to the user (step S108).

FIG. 13 is a diagram showing an example of a screen in which the terminal 2 accepts an operation of searching for a document from a user. The screen shown in FIG. 13 is composed of a dialog box D1 that interacts with the user. The dialog box D1 includes forms F1, F2, F3, and buttons B1, B2, B3.

When the user inputs the character string "Document A" in the form F1 and then presses the button B1 in which the character string "Search" is described, the processor 21 of the terminal 2 accepts these operations and the operation thereof is performed. A control signal indicating the content is sent to the information processing device 1.

When the processor 11 of the information processing apparatus 1 receives the above-mentioned control signal from the terminal 2, it is interpreted that the user is searching for the latest document for the document including the character string "document A". Then, for example, the processor 11 extracts a path including the character string "Document A" from the path DB 121 shown in FIG. 5, and instructs the terminal 2 to enumerate and display these extracted paths on the form F2. ..

Further, among these paths, the path indicating the last updated document is "folder D / document A_correction 2.odt". The processor 11 determines that the two messages shown in FIG. 12 have been exchanged after "November 18, 13:05", which is the update date and time of the document stored in this path, and interprets these. Notify the user that the document indicated by "Document A" may have been updated. Specifically, the processor 11 instructs the terminal 2 to display the character string "Mr. U12 may have updated the document A at 15:40 on 11/18" on the form F3. Then, the processor 11 instructs the terminal 2 to display the content of the conversation that is the basis for presuming that this document has been updated under the above-mentioned character string. This conversation is a message sent by the user represented by the user ID "U12" shown in FIG. 12 at 15:40 on November 18.

Here, the processor 11 estimates the user represented by the user ID "U12" as the user (referred to as the updated user) who has updated the document represented by "Document A". Then, the processor 11 presents the estimated update user information to the user of the terminal 2. That is, the processor 11 is an example of a processor that estimates an update user who is a user who has updated a document and presents information on the estimated update user. In addition to the user ID, the processor 11 may present the user's name, affiliation, e-mail address, account name in the message service, and the like as the update user information. With this configuration, the user can know the user who is presumed to have updated the document and query the user.

In addition, the processor 11 presents to the user of the terminal 2 the content of the conversation that is the basis for presuming that the above-mentioned document has been updated. That is, the processor 11 is an example of a processor that extracts and presents a message indicating the basis for presuming that the document has been updated from the analyzed messages. With this configuration, the user can confirm the message that is the basis for presuming the update.

Further, the processor 11 acquires date and time information indicating the date and time when the document (referred to as the first document) specified by the user was last updated in the document management device 4 (that is, the update date and time), and is obtained from this update date and time. When it is estimated that the first document was updated after the update date and time by analyzing the message exchanged later, the content of the above-mentioned conversation is presented to the user of the terminal 2 as the information of the first document. .. That is, the processor 11 acquires the date and time information indicating the date and time when the designated first document was last updated, and analyzes the messages exchanged after the date and time indicated by the date and time information among the messages. This is an example of a processor that presents information on the first document when it estimates whether the first document was updated after this date and time and estimates that the first document was updated after this date and time. According to this configuration, among the documents registered in the document management device 4, the documents having the document name specified by the user and the like are updated for the documents after the update date and time of the last updated document. The user can know when a message that is presumed to have been exchanged is being exchanged.

Further, when the processor 11 receives an operation for searching the first document from the user, the processor 11 acquires the date and time information of the first document, and the first document is updated after the date and time indicated in the date and time information. This is an example of a processor that presents the information of this first document to the user when estimating.

The processor 11 analyzes the messages exchanged after the update date and time to determine whether or not the designated first document has been updated, but the update date and time in the document management device 4 is not used.

<Operation to update the prediction model>
FIG. 14 is a flow chart showing an example of an operation flow for updating a prediction model. The processor 11 instructs the terminal 2 to display a document presumed to have been updated, prompting confirmation of whether or not the document has been updated (step S201). Then, the processor 11 determines whether or not the confirmation information about the document has been received from the terminal 2 (step S202).

FIG. 15 is a diagram showing an example of a screen for receiving confirmation information of a user in the terminal 2. The processor 11 instructs the terminal 2 to display the dialog box D2 shown in FIG. 15 by the display unit 25. This dialog box D2 displays a character string of the question "Have the document been updated?" And buttons B11 and B12 below this character string.

Button B11 is a button in which the character string "Yes" is described, and indicates that the user has confirmed that "the document has been updated". Further, the button B12 is a button in which the character string "No" is described, and indicates that the user has confirmed that "the document has not been updated".

When the user presses the button B11 or the button B12, the terminal 2 transmits these operations to the information processing apparatus 1 as the above-mentioned confirmation information.

In the operation shown in FIG. 14, the processor 11 continues this determination while it is determined that the confirmation information is not received from the terminal 2 (step S202; NO). On the other hand, when it is determined that the confirmation information has been received from the terminal 2 (step S202; YES), the processor 11 acquires the received confirmation information, stores the confirmation information, and uses the confirmation information to make a prediction model. Update 124 (step S203). After that, the processor 11 analyzes the message stored in the message DB 123 by using the updated prediction model 124.

The processor 11 that executes this "operation to update the prediction model" receives confirmation information confirming whether or not the document has been updated from the user presented with the document information, stores it in the memory, and uses this confirmation information. This is an example of a processor that parses messages. According to this configuration, the information processing apparatus 1 can improve the accuracy of estimation using the prediction model 124 by performing so-called supervised learning using the confirmation information obtained from the user as teacher data.

Although the processor 11 prompts the user's confirmation information from the terminal 2, the prediction model 124 may be updated by monitoring the user's operation by the information processing system 9. For example, when the processor 11 presents the information of the document estimated to be updated to the user and then the updated document is registered in the document management device 4, the processor 11 positively evaluates the estimation and uses the prediction model 124. Update. On the other hand, when the above-mentioned document is not updated and is not newly registered in the document management device 4 for a predetermined period, the processor 11 negatively evaluates the above-mentioned estimation and makes a prediction model. 124 may be updated.

By performing the operations described above, the information processing device 1 of the information processing system 9 is a designated document and is exchanged after the latest update date and time among the documents registered in the document management device 4. From the content of the message, it is determined whether or not the document has been updated since then, and when it is presumed that the document has been updated, the information of the document is presented to the user. As a result, the user can know the existence of the updated document even if it is not registered in the document management device.
