Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for automatically extracting an index word from a document.
The present invention relates to an index creation support device that reduces the labor of a document creator and a computer-readable recording medium that records a program for causing a computer to function as the device.

[0002]

2. Description of the Related Art A word processor is equipped with various functions for supporting document creation, such as creation of a footnote, a table of contents, and an index. In particular, since it takes a great deal of labor to manually create an index, the function of supporting the creation of an index greatly contributes to reducing the labor of the document creator.

Here, a function for supporting the creation of the index will be specifically described. First, by specifying an arbitrary range of a document being edited by a word processor, a word to be an index word is specified. By repeating this process a plurality of times, it is possible to specify a plurality of words to be used as index words. When the designation of the word to be used as the index word is completed, next, format settings such as how to arrange the index words to arrange in alphabetical order or alphabetical order and where to position the page number are made. After that, when indexing is specified and the indexing position is specified, the word in the document corresponding to the word specified in the range is searched, and the process of obtaining the page where the word exists and the processing of the obtained word Sorting processing and the like are automatically performed, and an index is created at a specified position.

[0004]

However, in the above-mentioned conventional technology, an index can be automatically created, but a user must specify which word is to be used as an index word. Since the process of searching for a word to be a word from a document is still required, there is a problem that it is still insufficient to reduce the labor of the document creator.

The present invention has been made in view of the above, and has as its object to reduce the labor of a document creator by automatically extracting an index word from a document. And

[0006]

According to an aspect of the present invention, there is provided an index creation support apparatus for creating an index of a document, wherein a document displayed on a screen is input. And analyze, and based on the analysis results,
A noun phrase list generating means for extracting a noun phrase included in the document to generate a noun phrase list, and a noun phrase list generated by the noun phrase list generating means, and inputting a noun phrase in the input noun phrase list For each of them, a calculating means for calculating statistical data such as an appearance frequency and distribution in the document, and a score is given to each of the noun phrases based on a calculation result of the calculating means, and the noun phrases are arranged in the order of the scores. And an index word list generating means for generating an index word list in which are arranged.

According to a first aspect of the present invention, there is provided a computer-readable recording medium on which a program for causing a computer to function as each unit of the index creation support device according to the first aspect is recorded.

Reference numeral 107 denotes a display such as T, and reference numeral 107 denotes a bus for connecting the above-described units.

The summary creation support device of the present embodiment is realized by reading and executing the index creation support software 104. The index creation support software 104 includes a floppy disk, a C
The program can also be recorded on a computer-readable recording medium such as a D-ROM, an MO, and a DVD, and can also be executed by being read from these recording media. This program can be distributed via the recording medium or via a network.

FIG. 2 is a schematic block diagram showing the processing of the index creation support software 104. The index creation support software 104 extracts an index word from a document and creates an index word list. The index creation support software 104 creates an index word list for the document 200 to be indexed displayed on the screen (edited by a word processor or the like). The input document 2 is input using a dictionary 202 storing information such as part of speech and a grammar dictionary 203 storing grammar rules.
00, a natural language processing module 201 that generates a noun phrase list 204, and a noun phrase list 204 from the natural language processing module 201, and an index word list 206 is generated based on the input noun phrase list 204. And an index word generation engine 205 to be created.

Next, the operation of the above-described index creation support device will be described in detail. FIG. 3 is a flowchart showing the operation of the index creation support device. The user can instruct index creation for the document displayed on the screen, and create an index using the index creation support software 104.

FIG. 4 is an explanatory diagram showing a state in which index creation is designated when a document is being edited by the word processor 400. When creating an index for the document 200, the user selects “automatic index creation” from the menu 401.

When index creation is specified (S301), the index creation support software 104 displays the document 2 displayed on the screen.
Then, a process of inputting and analyzing 00 is performed (S302).

More specifically, a natural language processing module 201 of the index creation support software 104 inputs a document 200 and uses a dictionary 202 and a grammar dictionary 203 to perform morphological analysis, identification of main words or phrases, and semantic information. It performs processing such as the addition of text, syntax analysis, analysis of reference expressions, and determination of the same pointer.

Subsequently, the natural language processing module 201
Is based on the analysis result of step S302.
0 is divided into a plurality of predetermined sentences called sub-documents, a noun phrase is extracted from the sub-document, and the extracted noun phrases are listed in a noun phrase list 20.
4 is generated (S303).

The index word generation engine 205 inputs the noun phrase list 204 generated by the natural language processing module 201 and, for each of the noun phrases in the input noun phrase list, generates statistical data such as the appearance frequency and distribution in the document 200. The calculation is performed (S304).

After calculating the statistical data in step S304, the index word generation engine 205 scores each noun phrase in the noun phrase list based on the statistical data calculated (S305). This score can be found in Document 2
It represents the importance of each noun phrase in 00, and the higher the score, the higher the importance.

The index word generation engine 205 determines in step S
Based on the result of the scoring performed in 305, an index word list 206 in which noun phrases are arranged in order of score is generated and output (S306).

Here, the index word generation engine 205 does not output all the noun phrases as the index word list 206, but sets a threshold value in advance, and outputs only the noun phrases having a score exceeding the threshold value. They may be output together in the index word list 206. That is, since an index word is an important word in a document, by setting a score threshold in advance, only an important word serving as an index word can be obtained.

The index word list 206 output from the index word generation engine 205 is displayed on the screen of the word processor 400. FIG. 5 is an explanatory diagram showing a state where the index word list 206 is displayed on the screen. When the user checks the index word list displayed on the screen and specifies the position where the index is to be created, the index in the document 200 is created as shown in FIG.

In the above description, after displaying the index word list 206 on the screen, the index is created by specifying the position where the index is to be created. However, by specifying the position in advance, the index can be specified. An index may be automatically created at a position where the index is set.

Although a detailed description is omitted, before creating an index, it is possible to set index format items such as whether to arrange index words in Japanese alphabetical order. As a result, the index creation support software 104 creates an index according to the items set by the user.

Alternatively, the user may be able to select a desired word from the index word list 206 displayed on the screen as shown in FIG.

The index created as shown in FIG. 6 can be edited by the user using the word processor 400.

Also, the index word can be registered in the document information of the document as a keyword for document search, and the registered index word can be used for document search.

Further, in order to cope with a case where a document is updated, an index created as described below can be managed. First, the date when the index was created is registered in the document file as document information of the document, and is used for updating the index when the content of the document is updated. Specifically, the date when updating and saving the document is compared with the date when the index was created, and if the date when the index was created is earlier than the time of the update, the index is automatically updated. Then, a process of updating and saving the data is performed. When a document is read, the date of updating (creation) of the document is compared with the date of creating the index. If the date of creating the index is earlier than the time of updating the document, the index is updated. The document may be displayed on the screen by automatically performing the updating process.
In updating the index, a dialog box for asking the user whether to update the index may be displayed on the screen.

Second, instead of using the date when the index was created as a reference, the number of pages of the document is used as a reference for updating the index. This is to record the page number of the document when the index was created, and to automatically update the index when the document is updated to have a different page number from the recorded page number It is to be.

In the first and second examples, the created index is automatically updated.
The index may be updated manually.

As described above, according to the index creation support apparatus of the present embodiment, the words serving as the index terms can be automatically extracted from the document, thereby reducing the labor of the document creator. be able to.
