2. Description of the Related Art In conventional information processing technology, natural language processing technology using various analysis methods such as syntax analysis and semantic analysis has been developed. Also, WordNet and ED
Ontology dictionary technology such as R, vector sp
Full-text search technology such as ace model, and concept search technology based on natural language query or direct concept specification have been developed. Further, multi-window application development technology such as MVC model has been developed.

[0003]

However, there is a problem that there is no comprehensive system for extracting and utilizing useful knowledge from large-scale document set data (for example, original text database). Hereinafter, the content of this problem will be described more specifically.

When extracting knowledge from original text data of a document, existing natural language processing technology or the like can be used. In addition, in creating a concept dictionary of knowledge, existing ontology dictionary technology or the like can be used. Also,
The existing concept search technology can be used for searching the original text, knowledge, and concept dictionary. Furthermore, the multi-window application development technology can be used to display the operation screens of a plurality of tools.

However, the knowledge extracted from the original sentence is structured to generate a knowledge structure (for example, the knowledge is displayed in a graph structure including nodes and edges), and a hierarchical concept dictionary corresponding to each knowledge structure is created. There was no optimal tool to do it. In other words, by starting from the management of the original text, managing the knowledge extraction, and converting to the concept dictionary collectively, for example, even words expressed by different words in the original text are the same in the computer if they are conceptually the same. The knowledge structure can be easily associated with each other by linking each knowledge structure element to the original sentence in the knowledge structure by a link or the like. By linking all the concept items of the knowledge structure element from each knowledge item, each concept item can have original text examples through the knowledge structure element, but there is a system to realize these comprehensively. I didn't.

Therefore, in order to realize such a function, conventionally, a plurality of types of tools have been used in combination, but in that case, each tool is required in terms of input / output interface and operability. However, it is not possible to simplify or streamline the operation on the operation screen of each tool, and there is a high possibility that the user may miss an operation or make an operation error. In other words, since the user needs to input data separately for each tool, there is a high possibility of typographical errors such as characters, and there are frequent omissions of reflection and creation of knowledge in other tools. It takes a lot of time to create a knowledge structure.

Further, when the knowledge or the like is changed, deleted, or added in any of the original text, the knowledge, or each of the operation tools of the concept dictionary, the information is updated in all other tools with respect to the knowledge. It was necessary to change, delete, and add, and automatic editing of knowledge was impossible.

Set as part of the original text.

Also, the shared cursor management unit 102i links the shared cursors on the concept dictionary operation screen and the knowledge structure operation screen. That is, the shared cursor management unit 102i
When the user moves the shared cursor on the concept dictionary operation screen, if the concept item at the move destination has a knowledge structure element having a link, the shared cursor on the knowledge structure operation screen is set to the knowledge structure element. Also, the shared cursor management unit 10
2i sets the shared cursor on the concept dictionary operation screen to the concept item when the user moves the shared cursor on the knowledge structure operation screen and the knowledge structure element at the destination has a link to the concept item. .

Further, the operation screen cooperation unit 102h, by the process of the unique cursor management unit 102j, changes from the knowledge structure element indicated by the knowledge structure operation screen unique cursor (MC-2) to the original text operation screen unique cursor (MA-2). The operation of linking / releasing a part of the original text marked with is executed as follows.

First, the peculiar cursor management unit 102j extracts the concept dictionary operation screen peculiar cursor (MB) from the knowledge structure element indicated by the knowledge structure operation screen peculiar cursor (MC-2).
The operation of linking / releasing the conceptual item indicated by -2) will be described below.

When the user changes the mark type or the mark range on the original text operation screen, the unique cursor management unit 102j performs one of the following processes depending on the mark type or setting. 1) Break the link from the knowledge structure element to the part of the original text with the mark. 2) This cancellation processing is performed, and the unique cursor is moved to the knowledge structure element whose link has been canceled to prompt the setting of the link to the original sentence. 3) This release processing or this link setting promotion processing is performed only when the range of the mark is changed. 4) Change the link to the post-change mark that contains the most words that compose the range of the pre-change mark. 5) This link replacement processing is performed, the cursor is moved to the knowledge structure element to which the link has been replaced, and confirmation of the replaced link is prompted according to the setting.

When the user changes or deletes the definition of a concept item on the concept dictionary operation screen, the operation screen cooperation unit 102h performs any one of the following processes depending on the setting. 1) Break the link from the knowledge structure element to the concept item. 2) This link release processing is performed, and the cursor is moved to the knowledge structure element for which the link is released to prompt the setting of the link to the conceptual item. 3) Change the links to the conceptual items (ancestors, siblings, descendants) close to the conceptual item before the change.
4) This link replacement processing is performed, the cursor is moved to the knowledge structure element to which the link has been replaced, and confirmation of the replaced link is prompted according to the setting.

When the user designates two types of stamps in the original text and newly creates a knowledge structure, the operation screen cooperation unit 1
02h instructs conversion to a relational knowledge structuring element with one type (denoted as A), and another type (denoted as B)
To instruct conversion to related object type knowledge structure element. In this case, the operation screen cooperation unit 102h creates the knowledge structure in the following procedure. First, in the operation screen cooperation unit 102h, the mark B
When the patterns are continuous in the pattern of -AB ', the relation object type knowledge structuring elements b1 and b2 are created, and the links to the B mark portion at the front and the B'mark portion at the rear of the original sentence are respectively linked.
Then, the operation screen cooperation unit 102h creates the relational knowledge structure element a and links to the A mark of the original sentence. And
The operation screen cooperation unit 102h extends a link to b1 as a relation source knowledge structure element and a link to b2 as a relation destination knowledge structure element of the relational knowledge structure element a. On the other hand, the mark is A-
If the pattern is either A ', begins with A'from the beginning of the sentence, or ends with A at the end of the sentence, the operation screen cooperation unit 102h indicates that the content is empty and the mark of type B is A of the original sentence. Apply the first procedure as if it were immediately before the'marked part or immediately after the A mark. Further, in the case of a pattern in which the mark is BB ′, the operation screen cooperation unit 102h applies the first procedure assuming that the mark having the empty content and the type A is between the original text B and B ′. Then, the operation screen cooperation unit 102h leaves the operation record in a predetermined storage area of the storage unit 106. With this,
The operation screen cooperation process ends.

[Knowledge Accumulation Processing] Next, details of the knowledge accumulation processing will be described. The knowledge accumulation work using this system follows the procedure below.

First, the original text is marked. The original text may be used for marking with a unique reference, or a general syntax analysis processing system may be used for adding a syntax tag. In the latter case, check the processing result on the original text operation screen and correct it if necessary.

Then, the above-mentioned operation screen cooperation processing is performed by the processing of the operation screen cooperation unit 102h, and a model of the knowledge structure is created. The type of mark to be converted into the relational knowledge structure element and the type of mark to be converted into the relation target type knowledge structure element are determined by one of the following methods. First of all, if you mark with a unique standard, the type of mark that you put a lot on the part that is supposed to correspond to the relation is the relation type knowledge structure element Corresponds to the related object type knowledge structure element. On the other hand, when a mark is applied using a general parsing system, the type of the mark attached to the verb is the relational knowledge structure element, and the type of the mark attached to the noun phrase or noun clause is the target of relation. Corresponds to the type knowledge structure element.

Then, the knowledge accumulation unit 102k confirms / edits the knowledge structure element on the knowledge structure operation screen. Also, if necessary, refer to the original text operation screen and use the shared cursor interlocking function. Then, the knowledge accumulating unit 102k deletes the knowledge structuring element that is determined to be not worth accumulating. In addition, the knowledge storage unit 102k adds a knowledge structuring element that does not exist in the original text but is worth storing. Also, if there is a source part that is closely related to the added knowledge structure element,
The knowledge storage unit 102k establishes an original text link.

Then, the knowledge accumulation unit 102k changes the display attributes (text label, size, position, shape, color, etc.) of each knowledge structure element on the knowledge structure operation screen. Then, the knowledge accumulating unit 102k uses the knowledge structure operation screen and the concept dictionary operation screen in combination, and establishes a concept item link using the concept item link operation function. This process is applied to all knowledge structure elements.

Here, if there is a knowledge structure element for which an appropriate concept item cannot be found, the knowledge accumulating unit 102k performs any of the following processes. On the knowledge structure operation screen, create the optimum concept item for the knowledge structure element, and link the concept item to it. Select a concept item that means undefined concept from the knowledge structure operation screen, and link a concept item to it. This completes the knowledge accumulation process.

Then, the knowledge structure is accumulated by the above-mentioned method. At this time, the original sentence is selected and the processing is proceeded by planning so as to link all the concept items in the hierarchical concept dictionary. This source text selection is performed by randomly selecting the source text, creating a set of concept items that are not linked to concept items, and then selecting from them. Select one of the original texts, or combine them.

Then, the document knowledge automatic editing unit 102g is
The knowledge structure is automatically generated by applying the following process to all available source sentences. First, the document knowledge automatic editing unit 102
g marks the original text stored in the original text database 106a. Use existing parsing system if necessary.

The document knowledge automatic editing unit 102g is
When the knowledge structure element is generated by the method described above, one of the following processes is applied to each generated knowledge structure element. A link is established from a knowledge structure element having an original text part that matches a case word of a concept item of the hierarchical concept dictionary stored in the concept dictionary database 106c to the concept item.
From the processed original text set, the original text database 106a is processed by using the existing natural language processing technique or the like with the original text A being processed as an argument.
A similar sentence is searched for to obtain the original sentence B.

Then, the document knowledge automatic editing unit 102g
With reference to the link to the concept item of the original sentence B, a link is established from the knowledge structure element corresponding to each part of the original sentence A to the conceptual item. When the estimation of the concept item link does not reach a certain standard, the document knowledge automatic editing unit 102g establishes a link to the concept item meaning the concept undefined.

Then, the document knowledge automatic editing unit 102g
The automatic generation process is repeated while confirming the knowledge structure generated in the above process. This completes the document knowledge automatic generation processing.
