Description

The present invention relates to a document management / viewing system, and more particularly to the generation and display of annotations that support the understanding of terms contained in a document managed by the document management / viewing system.

There is a document management / viewing system that accumulates and manages various documents, presents them by displaying or outputting documents searched or specified by the user, and makes them available for viewing by the user. The user searches for the required document and displays the searched document on, for example, a display screen of a computer. There are contracts and contracts as documents to be managed by the document management / viewing system, but it is difficult to understand these documents unless they are familiar with the terms and laws used in the contract. Similarly, there are manuals and regulation collections as documents to be managed by the document management / viewing system, but these documents are enormous in volume and it is difficult to immediately grasp the contents of the description. In order to properly understand a document managed by a document management / viewing system, it is necessary to know the meaning and definition of terms contained in the document, but that is actually difficult and the viewer of the document Whenever a term that you want to know in detail or a term that you do not understand is encountered, you need to search using that term as a key. For example, in the case of performing counter-service operations using a document management / viewing system, a document is searched based on an inquiry from the customer, and the content of the searched document is communicated to the customer. When a question arises about a term contained in a document, it is necessary to search within the document or another document containing the term using that term as a key, and only for the time required for another search. Business efficiency will decrease. For proper understanding of a document, it is required to be able to present commentary sentences explaining the terms contained in the document to the readers of the document in a timely manner.

As a way to timely present commentary on a term contained in a document to the viewer of the document, the document itself is constructed as a hypertext document, and a file containing the commentary for that term is linked to the document for each term. The method of embedding is known. According to this method, if a term is clicked with a mouse or the like while the document is being displayed on a display device of a computer, for example, a browser or the like is started and an annotation sentence for the term is displayed. Further, Patent Document 1 is a document management / browsing system, and when a term in a displayed document is selected by a mouse operation or the like, the selected term is used as a key in the document management / browsing system. We disclose a system that can display search results by searching documents and searching on the Internet.

Japanese Unexamined Patent Publication No. 2006-79366

The method described in Patent Document 1 performs a search using a term included in the document and selected by the user as a key, but guarantees that a search result useful for understanding the term is always obtained. is not it. On the other hand, when a document is a hypertext document and a link to a file of annotations about the terms is embedded in the terms contained in the document, it is necessary to create annotations for each term in advance and make it a file. It takes a lot of effort to create. In particular, when the amount of documents stored in the document management / viewing system is large, it takes a lot of work time to create the annotation text, which makes it unrealistic to execute it manually. Even if a commentary is created, the commentary may become inappropriate over time, for example, the name of the law may be changed due to a revision of the law after the commentary is created. It also costs a lot to keep the annotations to fit.

An object of the present invention is a document management / viewing system capable of displaying the latest and appropriate annotation text for a term when a term contained in the document is selected, and reducing the labor required for creating and maintaining the annotation text. The purpose is to provide a method for generating and displaying the annotation text.

It is characterized by having.

In order to achieve the above object, the annotation sentence generation display method of the present invention is:
In the annotation sentence generation and display method in the document management / viewing system that accumulates and manages documents and presents them to users
The steps to display the documents stored in the document management / viewing system to the user,
For the term selected by the user in the document displayed to the user, a step of generating an annotation sentence corresponding to the term by artificial intelligence, and a step of generating a commentary sentence corresponding to the term.
A step of displaying the generated annotation text to the user, and
It is characterized by having.

In the present invention configured as described above, when a user selects a term in the displayed document, an annotation sentence is generated and displayed by using artificial intelligence with respect to the selected term. By using artificial intelligence, it is possible to display the latest and accurate annotations to the terms in the document to the user in a timely manner without human intervention, and the effort required to create and maintain the annotations. Can be reduced.

In the present invention, the commentary text searches for and obtains related documents related to the term selected by the user from at least the documents stored in the document management / viewing system, and uses artificial intelligence to summarize the related documents. It can be generated by generating a sentence and making it an annotation sentence. By using the term selected by the user as a search key, for example, by searching the documents stored in the document management / viewing system and acquiring the related documents, the latest existing in the document management / viewing system is obtained. Since the related document, which is a version of the document, can be obtained and the summary sentence can be generated, the latest and appropriate commentary sentence for the term can be generated.

In the acquisition of related documents, not only the related documents may be acquired from the documents stored in the document management / viewing system, but also the related documents may be searched and acquired from an external server connected via a network such as the Internet. .. By acquiring the related document from the external server, it is possible to generate an annotation even if an appropriate related document cannot be acquired from the document stored in the document management / viewing system. However, since there is a high possibility that the related documents acquired from the external server include those equivalent to search noise, the related documents acquired from the document management / viewing system should be used with priority when generating the summary sentence. Is preferable. In addition, when a certain number of related documents are acquired, the similarity with the term is calculated for each related document, and a summary sentence is generated from a predetermined number of related documents whose similarity exceeds the threshold value. It is preferable to do so. By selecting related documents based on the degree of similarity, it is possible to obtain annotations with more appropriate contents. In addition, by aggregating the information scattered in a plurality of related documents, it is possible to obtain an annotation sentence including more appropriate information at once.

According to the present invention, when a term contained in a document is selected, the latest and appropriate commentary for the term can be displayed, and the labor required for creating and maintaining the commentary can be reduced.

It is a block diagram which shows the structure of the document management / viewing system of one Embodiment of this invention. It is a flowchart which shows the process of generating an annotation sentence. It is a figure which shows the selection of the term in a document, and the display of an annotation sentence.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a document management / viewing system according to an embodiment of the present invention. The document management / viewing system 10 is composed of, for example, a computer for a server, and accumulates and manages documents generated in a business entity or the like, and displays or outputs a document searched or specified by a user. Presented by the user for viewing.

One or more terminals 50 used by the user are connected to the document management / viewing system 10 via a network 30 such as a local area network (LAN) or a virtual private network (VPN). As the terminal 50, a personal computer or the like provided with a graphical user interface (GUI) is used, and the document displayed to the user by the document management / viewing system 10 is displayed on the display device of the terminal 50. The document management / viewing system 10 includes a storage unit 11 for accumulating documents to be managed by the document management / viewing system 10, an annotation sentence generation unit 20 for generating annotation sentences, and a control unit 13. The commentary sentence is a sentence that explains each term contained in the document stored in the storage unit 11 and supports the understanding of the term, and is generated by using artificial intelligence (AI). It is a thing. In this embodiment, the commentary is generated on demand, i.e. when it is needed, as described below.

The control unit 13 is a part of the document management / viewing system 10 that serves as an interface with the user's terminal 50 via the network 30, and searches and searches for documents in the storage unit 11 based on a request from the user. The process of displaying the created document on the display screen of the user's terminal 50 is executed. Further, when the user selects a term included in the document on the screen of the terminal 50 in the document displayed on the screen of the user's terminal 50, the control unit 13 selects the term from the terminal 50. Upon being notified, the comment statement generation unit 20 is made to generate a commentary sentence based on the notified term, and a process of displaying the generated commentary sentence on the screen of the user's terminal 50 is also executed. The function of executing these processes of the control unit 13 can be realized by a computer program executed in the document management / viewing system 10 configured by the server computer.

The annotation sentence generation unit 20 uses artificial intelligence and a related document acquisition unit 22 that searches and acquires at least the related documents related to the terms notified from the terminal 50 from the documents stored in the storage unit 11. It includes a summary sentence generation unit 23 that generates a summary sentence of a related document as a commentary sentence. Here, the related document is a document that may include explanations and explanations about the target term. In many cases, the relevant document also includes the term itself in question.

The terminal 50 displays a document or commentary sent from the document management / viewing system 10 on the screen, and when a term included in the document displayed on the screen is selected by the user, the term is displayed. It has a function to send to the document management / viewing system. The function of such a terminal 50 is executed by general browser software or a dedicated application. Of the document management / viewing system 10, the function of the control unit 13 can also be realized in the terminal 50.

Next, the process of generating an annotation sentence will be described with reference to FIG. First, in step 101, the control unit 13 receives a term selected by the user in the document displayed to the user on the terminal 50 from the terminal 50, and transfers the term to the annotation sentence generation unit 20. Then, in step 102, the related document acquisition unit 22 searches for and acquires the related document from the documents stored in the storage unit 11 using the transferred term as a search key. A large number of documents containing the transferred terms may be searched, and in that case, a document suitable for generating a summary sentence used as an annotation sentence is set as a related document. Since it is appropriate that the related document explains the target term, it is possible to narrow down the related document by examining the relationship between the reference and the reference to the target term. Alternatively, after obtaining a distributed representation of the term using "FastText" software or the like, the similarity of the document to the term is calculated by using a method such as cosine similarity to the document that is a candidate for the related document. Related documents may be selected based on similarity. You may use the "Doc2Vec" software to select relevant documents based on their similarity to the term. When narrowing down related documents based on the similarity to terms, basically, the documents with high similarity are regarded as related documents. By selecting related documents based on the degree of similarity, it is possible to obtain annotations with more appropriate contents. When more than a certain number of documents that are candidates for related documents are acquired, a summary sentence is generated from those related documents with a predetermined number of documents whose similarity exceeds the threshold value as related documents. Can be done. In this case, since the information scattered in a plurality of related documents is aggregated, it is possible to obtain an annotation sentence including more appropriate information at once. The threshold value and the predetermined number are predetermined according to the calculation method of the similarity and how many related documents the summary sentence is generated from.

In the above description, the related document acquisition unit 22 acquires the related document from the documents stored in the storage unit 11, but it is also possible to expand the search range of the related document. As shown by the broken line in FIG. 1, when the external server 61 is connected to the external network 60 such as the Internet, the related document acquisition unit 22 acquires the related document from the document stored in the external server 61. May be good. By acquiring the related document from the external server 61, it is possible to generate an annotation sentence even when an appropriate related document cannot be acquired from the document stored in the storage unit 11.

Subsequently, in step 103, the summary sentence generation unit 23 generates a summary sentence from the related document acquired by the related document acquisition unit 22 using artificial intelligence. The abstract is generated using, for example, "LexRank" software. When there is a related document acquired from the storage unit 11 and a related document acquired from the external server 61, the related document acquired from the storage unit 11 is prioritized to generate a summary sentence. This is because there is a high possibility that the related documents acquired from the external server 61 include those corresponding to the search noise, and there is a possibility that some of them lack accuracy. After that, in step 104, the summary sentence generation unit 23 outputs the generated summary sentence as a commentary sentence to the control unit 13, and the control unit 13 displays the commentary sentence on the display screen of the user's terminal 50. The commentary is transmitted to the terminal 50.

Although the generation of the annotation text in the present embodiment has been described above, the software of "FastText", "Doc2Vec", and "LexRank" is open source software and can be easily implemented. Software for calculating cosine similarity and the like is also available as open source software. In the present embodiment, the comment statement generation unit 20 can be realized by software executed on the document management / viewing system 10 configured by the server computer.

Next, the selection of terms in the document and the display of the annotation text on the user's terminal 50 in the present embodiment will be described with reference to FIG. Assuming that any of the documents stored in the storage unit 11 of the document management / viewing system 10 is displayed on the display screen of the terminal 50, FIG. 3 shows a state in which the document is displayed on the display screen. .. The document is displayed in the document display window 70 in the display screen. Assuming that the document is, for example, a hypertext document or a PDF (portable document format) document in which a character code is embedded, the user can select a character string included in the displayed document by using a mouse or the like. Can be done. If the display screen is a touch panel, the character string can be selected by placing a finger on the first character of the target character string and dragging the range of the character string. In the present embodiment, the character string selected on the display screen is the term selected by the user in the displayed document. In FIG. 3, the character string 71 of the “personal information protection policy” surrounded by a square is the selected term. It is preferable that the selected character string 71 is highlighted by changing the display color or the background color of the portion of the character string 71. If you select a string in your browser or PDF document, that string is usually highlighted. Further, in the displayed document, if the same character string as the selected character string exists in a place other than the selected place, the same character string in those places may be highlighted.

Then, when the user calls the context menu by right-clicking the mouse, for example, with the term selected and selects "display annotation text" in the context menu, the selected term is transmitted to the control unit 13, and the selected term is transmitted to the control unit 13. As a result, the annotation sentence generation unit 20 generates an annotation sentence corresponding to the term, and the generated annotation sentence is sent from the control unit 13 to the terminal 50. In the terminal 50, the character string 71 selected on the display screen is displayed. Correspondingly, the blowout 72 appears as shown in FIG. Inside the balloon 72, an annotation text generated for the selected term (here, "personal information protection policy") is displayed. As a method of displaying the annotation text, in addition to the method of using a balloon, the method of using a pop-up window, the method of using a new tab or another page, the method of using another column, the method of using a new or another window, and the like. "Display annotation text" is added to the context menu, and when "Display annotation text" is selected, the data of the selected term is sent to the control unit 13, and the annotation text sent from the control unit 13 is sent. Can be displayed in some form by a dedicated application, and even when a general browser is used, it can be realized by the setting in the browser and the setting of the operating system (OS) of the terminal 50.

According to the document management / viewing system 10 of the present embodiment, when a user selects a term in the document displayed on the terminal 50, an annotation sentence for the term is automatically generated by artificial intelligence and the terminal 50 is used. Is displayed on the display screen. The user can display the commentary text explaining the terms in the document on the screen in a short time, and according to this document management / viewing system 10, it is possible to support the user's understanding of the document. .. Since the annotation text is generated using artificial intelligence at the time of the user's request, it is possible to obtain an accurate annotation text with the latest contents and reduce the labor required for creating and maintaining the annotation text. According to the present embodiment, for example, when the document management / viewing system 10 of the present embodiment is used for the counter-correspondence work, it is possible to reduce the time for searching to find out the meaning of terms contained in the document, and the customer can reduce the time. It will be possible to respond quickly to inquiries, which will greatly improve work efficiency.
