As shown in the example of FIG. 1, a document storage module 110, an operation history storage module 120, It has a difference generation module 130, an extraction module 140, a recommended notification destination determination module 150, a difference division module 160, a recommended additional difference determination module 170, and a notification message creation module 180.
Here, the document is mainly text data, in some cases, electronic data (also referred to as a file) such as graphics, images, moving images, audio, etc., or a combination thereof, and is a target for storage, editing, retrieval, etc. Or what can be exchanged as an individual unit between users, including those similar to these. Specifically, it includes a document created by a document creation program, a Web page, and the like.
The document is updated by editing. There is a scene that notifies a related user when updating the document and requests confirmation. At this time, it is necessary to give the appropriate difference information to the appropriate notification destination to convey the updated contents. In addition, there is a possibility that the part of interest / interest is different for each notification destination.
The notification destination is exemplified by a user in the following description, but may be a group composed of a plurality of people, or may be a name (such as a title) that does not specify an individual.

The document storage module 110 is connected to the difference generation module 130, the extraction module 140, and the recommended notification destination determination module 150. The document storage module 110 stores a document. When the document is updated, the document before the update and the document after the update are stored. The document update occurs when the document is edited (including addition, change, deletion, etc.). Also, document generation (new creation) and document deletion may be included.
The operation history storage module 120 is connected to the extraction module 140, the recommended notification destination determination module 150, and the recommended additional difference determination module 170. The operation history storage module 120 stores a history of operations performed by the user. The operations include operations such as browsing and searching for documents in addition to document editing operations. Note that the user performs an operation using a mouse, a keyboard, a touch panel, sound, a line of sight, a gesture, and the like.
The difference generation module 130 is connected to the document storage module 110, the recommended notification destination determination module 150, and the difference division module 160. The difference generation module 130 receives the document before and after the update, and extracts difference information between the received document before the update and the document after the update. In addition to text, figures, images, and the like may be included as differences. As the extraction of the difference information, in addition to extracting and comparing the document before the update and the document after the update, the difference information may be extracted using history information of editing the document. The difference information extraction process may be performed using an existing technique.

  The extraction module 140 is connected to the document storage module 110, the operation history storage module 120, the recommended notification destination determination module 150, and the recommended additional difference determination module 170. The extraction module 140 extracts information related to the notification destination (user). For example, as information about the notification destination, information related to operations related to documents such as document names, contents, search keywords, etc. created in the past for each user, attribute information of the user such as title, group name, organization name, etc. There is information about. In addition, the extraction module 140 extracts words (words) having a high appearance frequency or characteristic from those pieces of information as interesting words. Here, “the appearance frequency is high” means that the number of times of the word is greater than or equal to a predetermined threshold, and the appearance ratio of the word with respect to the total number of words that appear is greater than or greater than the predetermined threshold. There may be a technique such as being, or tf-idf (term frequency-inverse document frequency). The “characteristic phrase” is a phrase that is used by the target user but is not used by other users, and is determined by the frequency of the phrase for each user.

The recommended notification destination determination module 150 is connected to the document storage module 110, the operation history storage module 120, the difference generation module 130, the extraction module 140, and the notification message creation module 180. The recommended notification destination determination module 150 determines a notification destination for notifying that the document has been updated according to the degree of matching between the information about the notification destination extracted by the extraction module 140 and the difference information extracted by the difference generation module 130. To do.
Further, the recommended notification destination determination module 150 further uses the browsing history of the document (updated document) by the notification destination or the browsing history of the document (document other than the updated document) created by the updater of the document. The notification destination for notifying that the document has been updated may be determined.

  The difference division module 160 is connected to the difference generation module 130 and the recommended additional difference determination module 170. The difference division module 160 divides the difference information extracted by the difference generation module 130 into blocks using a document structure (hierarchical structure, sentence breaks, etc.) including the difference information. Here, examples of the “document structure” include a hierarchical structure and sentence breaks. For example, the difference information may be divided for each sentence (each phrase). In addition, the document created using the document creation program includes a document having a hierarchical structure. In such a document, the difference may be divided for each paragraph as a hierarchy.

The recommended additional difference determination module 170 is connected to the operation history storage module 120, the extraction module 140, the difference division module 160, and the notification message creation module 180. The recommended additional difference determination module 170 sets the notification content to the notification destination according to the degree of matching between the information related to the notification destination determined by the recommended notification destination determination module 150 and the difference information extracted by the difference generation module 130. Determine the difference information. Further, the difference information divided by the difference division module 160 may be used as a target for calculating the fitness.
Further, the recommended addition difference determination module 170 further notifies the notification destination that the document has been updated using the browsing history of the document by the notification destination or the browsing history of the document created by the updater of the document. May be determined.

  The notification message creation module 180 is connected to the recommended notification destination determination module 150 and the recommended additional difference determination module 170. The notification message creation module 180 creates a notification message with difference information added for each notification destination. For example, the notification message creation module 180 may present the difference information extracted by the difference generation module 130 for each notification destination so that the user can specify whether or not to notify. The notification message may be, for example, contents such as an e-mail or may be created as an attached document. The notification may be performed by e-mail, for example, or a function such as a message in SNS (Social Networking Service) may be used.

FIG. 2 is an explanatory diagram showing a system configuration example using the present embodiment.
The information processing apparatus 100, the user terminal 210, and the document processing apparatus 220 are connected to each other via a communication line 290. The communication line 290 may be wireless, wired, or a combination thereof, and may be, for example, the Internet or an intranet as a communication infrastructure. Documents are managed (including storage, editing functions, etc.) in the document processing apparatus 220, and the information processing apparatus 100 performs processing on the documents in the document processing apparatus 220. User A uses the user terminal 210 to edit a document. Then, the information processing apparatus 100 notifies the user terminal 210 of user B that the document has been updated. Note that the document processing apparatus 220 may include a document storage module 110 and an operation history storage module 120. The functions of the information processing apparatus 100 and the document processing apparatus 220 may be realized as a cloud service.

FIG. 3 is a flowchart showing an example of processing according to this embodiment.
The target document is an updated document. An updater is a user who has updated a document. The notification destination is a destination of the document update notification.
In step S302, the document is updated.
In step S304, the difference generation module 130 extracts difference information before and after the document update.
In step S306, the recommended notification destination determination module 150 determines a notification destination candidate. Determine who can be notified. For example, a user who has an access right to the target document and a user who belongs to the same access right group may be used as a notification destination candidate.

In step S308, the extraction module 140 extracts terms (phrases, words) in which the notification destination is interested. For example, terms are extracted by the following process (any one or a combination thereof).
・ Frequently used terms: The name of the document created and viewed by the notification destination in the past, the content of the document, the search keyword, etc. In particular, it is good also as terms etc. with high appearance frequency in them. “The appearance frequency is high” is as described above.
-Characteristic attribute information: Words and phrases included in attribute information such as group name and organization name. In particular, it may be a characteristic phrase or the like. The “characteristic phrase” is as described above.
Notification destination registration term: The notification destination is an interesting / interesting term, and may be, for example, a word registered in advance by the notification destination user.

In step S310, the recommended notification destination determination module 150 determines a notification destination to be recommended among the notification destination candidates. For example, if the following conditions are satisfied, it is recommended with priority.
-The difference information and the term of interest of the notification candidate match.
・ There is a browsing history of the target document.
-The browsing rate for documents created by the updater in the past (excluding target documents) is high.
If it is determined in step S306 that the user has access rights to the target document, the condition in step S310 may be that the updater and the notification destination belong to the same access right group. Conversely, if it is a condition that the user belongs to the same access right group in step S306, the condition in step S310 may be that the user has an access right to the target document.

In step S312, the difference dividing module 160 divides the difference information into blocks using a document hierarchical structure, sentence breaks, and the like. For example, in the case of a document having a hierarchical structure, the difference for each paragraph can be divided.
In step S314, the recommended addition difference determination module 170 determines whether or not each difference block is recommended as additional information of the update notification for each recommendation notification destination that is the processing result of step S310. For example, blocks that satisfy the following conditions are recommended with priority.
-The notification destination is a block that has been updated in the past.
-It is a block where the frequency of appearance of the term of interest is high.
In step S316, the notification message creation module 180 creates an update notification message with a recommended difference added for each recommended notification destination.
In step S318, an update notification message is transmitted.

  In addition, in the process of step S310, you may make it perform the process of step S306. In this case, the process in step S308 is a user who can be a notification destination. However, since it is unnecessary to perform the process of step S308 for users who cannot access the target document in the first place, it is efficient to perform the process of step S308 after performing the process of step S306. is there.

This will be described using a specific processing example.
An operation history table 400 for each user is stored in the operation history storage module 120. FIG. 4 is an explanatory diagram showing an example of the data structure of the operation history table 400. The operation history table 400 includes a date / time column 410, an operation column 420, and an operation target column 430.
The date / time column 410 stores the date / time (year, month, day, hour, minute, second, second or less, or a combination thereof) when the target operation is performed. The operation column 420 stores operations performed on that date and time. The operation target column 430 stores a target in the operation.
For example, creation (new upload), browsing (download), update (overwrite upload), and search are recorded as user operation history.
The operation history table 400 for each user is used for extracting words / phrases of interest to the notification destination.

Further, an operation history table 500 for each document is stored in the operation history storage module 120. FIG. 5 is an explanatory diagram showing an example of the data structure of the operation history table 500. The operation history table 500 includes a date / time column 510, an operation column 520, and an operator column 530. The date / time column 510 stores the date / time when the target operation was performed. The operation column 520 stores operations performed on the date and time. The operator column 530 stores a name (user name) indicating the operator who performed the operation.
For example, creation (new upload), browsing (download), and update (overwrite upload) are recorded as the operation history for the document.
The operation history table 500 for each document is used for determining a recommended notification destination, a recommended additional difference, and extracting additional information (viewing count).

For example, a case where the document A is updated will be described. In this document A, it is assumed that user B, user C, user D, user E, user F, user K, and user L have access rights.
(1) Notification destination candidate determination processing in step S306-As the notification destination candidates for document A, user B, user C, user D, user E, user F, user K, and user L who have access rights to document A are determined.
■ Recommended Notification Candidate Determination Processing in Step S310-Extracts users using terms of interest.
The user F having a high relevance ratio between the difference information and the interested term of the notification destination candidate is determined. The relevance ratio is determined by, for example, whether or not it appears more than a predetermined threshold. Thereby, users who are interested in the difference information can be extracted.
-Extract users using the browsing history of the target document.
Based on the browsing history for document A, a notification destination candidate is determined. For example, user B, user C, and user D who have a browsing history are added to the recommended notification destination candidates.
-Extract users using the browsing rate of documents created by the updater in the past.
Users E and F whose browsing rate of documents (excluding document A) created by the updater in the past is equal to or higher than a predetermined threshold are added to the recommended notification destination candidates.
-Extract users using access right groups.
Users F and L belonging to the same access right group as the updater are added to the recommended notification destination candidates.
From the above, user B, user C, user D, user E, user F, and user L are determined as recommended notification destination candidates. Although all users extracted in each process are included (logical sum process), the extraction conditions (logical product process) may be used as the extraction condition, and each process result is weighted. Scoring may be performed to extract users who are equal to or greater than a predetermined threshold.

The matching determination method between the difference information and the term that the notification destination candidate is interested in will be described in detail using a specific example.
It is assumed that “MFP”, “Scan”, and “FAX” are registered as terms that user B is interested in, and “5” is set as the threshold value for suitability determination.
At this time, if the number of appearances in the difference information is 5 for “MFP”, 3 for “Scan”, and 2 for “FAX” for terms that are interesting to User B, the total number of appearances is 10 It becomes.
Since the number of appearances is equal to or greater than the threshold value 5, it is determined that the difference information and the term in which the user B is interested match. That is, the user B is extracted as a recommended notification destination candidate.
It is also possible to weight the terms that the user is interested in and calculate the score (multiply the number of appearances by the weighting coefficient to obtain the score of each term and calculate the sum of the scores). Also, synonyms of terms that the user is interested in may be included. In that case, the weight of the synonym may be lighter than the weight of the original term (a term that the user is interested in).

The notification message creation module 180 displays the notification message creation screen 600 on a display device such as a liquid crystal display of the information processing apparatus 100, for example. FIG. 6 is an explanatory diagram showing a processing example according to the present embodiment.
The notification message creation screen 600 is divided into a mail transmission column 610 and an attached message column 620 in the row (horizontal) direction, and for each notification destination candidate user (user B column 630) extracted in step S306 in the column (vertical) direction. , User K column 640, user C column 650, user D column 660, and the like. A send button 690 is displayed on the notification message creation screen 600.
In the notification message creation screen 600, it is possible to select whether or not to send mail for each notification destination candidate and whether or not to attach each difference block.
Using the processing results obtained by the recommended notification destination determination module 150 and the recommended additional difference determination module 170, the flag of the check box indicating the presence / absence of mail transmission and the presence / absence of attachment for each difference block is automatically determined. Of course, the checkbox can be changed by the sender.
When the send button 690 is selected, an update notification with the changed part of the flag ON as attachment information is sent to the user whose mail transmission flag is ON.
As a specific example, the mail transmission column 610 includes a check box for instructing whether or not to notify that the document has been updated for each user. At the beginning of the display of the notification message creation screen 600, the user's check box extracted by the process in step S310 is checked in advance. Checking and unchecking may be performed by the operation of the user who performs the notification (the user who operates the notification message creation screen 600).
The attached message column 620 is for each difference information divided by the processing in step S312 (in FIG. 6, “1-1. Target model”, “2-2. Pre-setting”, “3-2. Confirmation of result”). Each has a check box for each user. Then, at the beginning of the display of the notification message creation screen 600, the check box of the difference information divided for each user extracted by the processing in step S314 is checked in advance. Checking and unchecking may be performed by an operation of a user who performs notification. Thereby, the difference information notified according to a notification destination can be selected suitably.
As shown in the user K column 640, no check box is displayed in the attached message column 620 of the user K whose check box 642 is not checked. This is because it is not necessary to specify the divided difference information for a user who does not need the notification itself. However, although the check box is displayed, the check box may not be able to be checked (a display form such as dimming may be used).

Further, the notification message creation module 180 may display the notification message creation screen 700 on a display device such as a liquid crystal display of the information processing apparatus 100, for example. FIG. 7 is an explanatory diagram illustrating a processing example according to the present exemplary embodiment.
The notification message creation screen 700 is divided into a notification destination information column 705, a mail transmission column 710, and an attached message column 720 in the row (horizontal) direction, and each notification destination candidate user (user B column) in the column (vertical) direction. 730, user K column 740, user C column 750, user D column 760, and the like. A send button 790 is displayed on the notification message creation screen 700.
In addition to the display of the notification message creation screen 600, notification destination information that serves as a hint for e-mail transmission determination such as the number of browsing times and the number of times of updating of the target document before updating the target document is displayed. This makes it easy for the user performing the notification to select the notification destination.
Then, in the attached message column 720, a difference (added part, deleted part) is displayed for each divided difference information. In the specific example, “+” is added to the added portion and the “−” is added to the deleted portion. The difference may be notified not only to the user who performs the notification, but also to the notification destination. As a result, both the user who makes the notification and the notification destination can confirm the details of the difference information.
Further, the reason why there is a check in the mail transmission column 710 and the attached message column 720 or the reason why there is no check may be displayed. For example, when the user B additional information button 731 is selected, the reason is displayed. In the case of a predetermined check pattern, the reason may be displayed even if the user B additional information button 731 or the like is not selected. For example, when the check box in the mail transmission column 710 is checked but the check box in the attached message column 720 is not checked (in the example of FIG. 7, the user C column 750), it is determined as the recommended notification destination. (In the example of FIG. 7, the additional information 770 “This user frequently browses documents created in the past.”) Is displayed. The generation processing of these reasons may be performed by extracting the determination conditions and the results in the recommended notification destination determination module 150 and the recommended additional difference determination module 170 and documenting them. Thereby, the user who performs the notification can confirm the reason why the notification destination is extracted.

You may make it display whether browsing was actually performed after giving notification.
