Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document management system in which a directory is created independently of a storage medium, and documents corresponding to the created directory can be collected, classified, and managed using a search technology. The present invention relates to a support device and a computer-readable recording medium storing a program for causing a computer to function as the support device.

[0002]

2. Description of the Related Art Documents stored in a storage medium such as a hard disk are generally classified and managed according to a logical division called a directory (or folder). This directory can be created by the user according to his / her preference in order to easily perform document management, and can be used to collect a plurality of documents related to the created directory.

[0003] Specifically, a user can create a directory called a subdirectory with respect to the original root directory, name the created subdirectory, and create a name thereunder with a word processor or the like. Documents can belong. Sub-directories can be further created under the created sub-directory, so that it is possible to manage documents in a hierarchical structure by creating directories at various levels. When reading a document, a list of document names in the directory is displayed by designating the directory, and a desired document can be read by selecting one of the listed document names.

[0004] Information on the above-mentioned directory is collected in a file and stored in a storage medium. In this file, the document name of the document stored in association with the directory, the position in the storage medium, and the like are recorded, and the document in the storage medium is managed by the directory name and the document name.

[0005]

However, in the above-mentioned conventional technology, it is possible to easily perform document management by using a directory. On the other hand, on the other hand, the document is classified and managed based on the directory. Therefore, there is a problem that documents can be classified only fixedly. In other words, since the documents are classified and managed based on the directory, when changing the method of classifying the documents, complicated work such as creating a new directory and moving the documents to the created directory is required. However, there is a problem that document classification and management are not convenient.

[0006] In addition, since documents are classified and managed mainly in directories, there is a problem in that when a created document is stored, it is necessary to specify a directory to which the document belongs. That is, when the operation of designating an appropriate directory is neglected, it is necessary to find the directory in which the document is stored when reading the document later.

[0007] Further, the directory has a one-to-one correspondence with a storage medium, and when a new storage medium is used, a directory created on another storage medium cannot be used as it is. There was a problem that it had to be created.

Furthermore, since documents are managed mainly in the directory, there is a problem that if the directory is broken by an erroneous operation, the documents in the directory cannot be read.

[0009] The present invention has been made in view of the above, and it is possible to create a directory independently of a storage medium and collect, classify, and manage documents corresponding to the created directory using a search technique. An object of the present invention is to improve the simplicity of processing when changing the method of classifying documents by making it possible.

Further, the present invention has been made in view of the above, and a directory is created independently of a storage medium.
By using search technology to collect, sort, and manage documents that correspond to the created directory, it is not necessary to specify the directory to which the document belongs when saving the document. It is an object of the present invention to simplify the storage operation as much as possible.

Further, the present invention has been made in view of the above, and a directory is created independently of a storage medium.
By making it possible to collect, classify and manage documents corresponding to the created directory using search technology, it is not necessary to create directories for different storage media, and to classify and store documents in the same environment. The purpose is to be able to perform management.

Furthermore, the present invention has been made in view of the above, and a directory is created independently of a storage medium, and documents corresponding to the created directory are collected, sorted, and managed by using a search technique. It is an object of the present invention to prevent a situation where reading of a document becomes impossible when a file related to a directory is damaged.

A document list 308 to which a score exceeding the score is given is output as a search result.

Although FIG. 1 shows a configuration in which the document DB 101 and the transposed file 102 are independently connected to the network 104, these may be directly connected to the search server 103. In FIG. 1, the document management support apparatus of the present embodiment is connected to a network 1
Although the system is shown to be configured via the system 04, the processing of the client 100 and the search server 103 may be performed by one computer.

Next, the operation of the document management support apparatus having the above-described configuration will be described with respect to (1) a process of generating an inverted file,
(2) Directory setting processing and (3) directory classification processing will be described in detail in this order.

(1) Transposition File Generation Process FIG. 4 is a flowchart showing a transposition file generation process. The search server 103 adds a new document (newspaper article)
Is registered in the document DB 101 (S401), a process for inputting this document and registering it in the transposition file 102 is started (S402).

In the search server 103, the natural language processing module 300 performs a process of analyzing the document input in step S402 (S403). Specifically, the input document is a word processing document, a structured document such as HTML, etc.
A process is performed to determine the format of the document. Thereafter, syntax analysis such as morphological analysis and dependency is performed by using the dictionary 301 and the grammar dictionary 302 to divide the document into a plurality of sub-documents, and to perform processing such as extracting a noun phrase from the divided sub-documents.

Then, the natural language processing module 300
Is based on the result of the processing in step S403.
A noun phrase list is generated for each sub-document, and a document set 303 including the generated noun phrase list is generated (S404).

Thereafter, the database build component 304 receives the document set 303 generated by the natural language processing module 300, generates a vector representation of the document, and registers it in the transposed file 102 (S405).

Specifically, the document set 303
Transpose file 102 for each noun phrase of subdocument in
The statistical information such as the frequency of occurrence in the sub-document and the distribution in the entire document DB 101 is obtained as an index term, and the sub-document is converted into a vector expression using the obtained statistical information for each noun phrase. This processing is performed for all the sub-documents in the document set 303, and based on the converted sub-document vector expression, a vector expression of the document is generated and registered in the transposed file 102.

(2) Directory Setting Process Next, a process of setting a directory for managing documents in the document DB 101 will be described. FIG. 5 is an explanatory diagram for explaining a directory setting process.

The user issues an instruction to the document management unit 202 using the input device 200 of the client 100, and sets the directory while checking the state of the screen displayed on the output device 203. First, the root directory 500
, A subdirectory 501 is created, and a directory name “sports” is assigned. And subdirectory 5
01, a corresponding document in the document DB 101 is searched,
A search condition 206 for displaying the document name is associated. The search condition 206 may be any of a search formula, a search sentence, a set of keywords, an example document, and the like. Further, a directory name given to the subdirectory 501 may be used as the search condition 206. Therefore, when the user selects the subdirectory 501, the associated search condition 206 is changed to the search server 103.
After that, a newspaper article relating to sports is retrieved from the document DB 101, and the document name, that is, the headline of the article, is displayed in the subdirectory 501. Information about the set directory is stored in the directory information storage unit 201.

As described above, the sub-directory 502 whose directory name is "science" and the sub-directory 503 whose directory name is "economic" are set in the same manner.

The AND condition can be set by further setting a subdirectory below the set subdirectory. For example, after designating the subdirectory 503, a subdirectory 504 whose directory name is “finance” and a directory 505 whose directory name is “industry” are created below the subdirectory 503. Then, the search condition 206 is associated with these. As a result, when the subdirectory 503 is selected,
An article related to "economy" is retrieved from the document DB 101, and the headline (document name) is displayed. When the subdirectory 504 is selected, an article related to “economy” and an article related to “finance” are stored in the document DB1.
01 and the heading is displayed.

FIG. 6 is an explanatory diagram showing an example of the result of performing the directory setting processing as described above. By setting the directory as shown in FIG. 6, the preparation for classifying the documents in the document DB 101 and displaying them on the screen is completed.

(3) Processing for Classifying into Directories Next, processing for classifying and managing documents in the document DB 101 based on the directories set as described above will be described. FIG. 7 is a flowchart showing the process of classifying a directory.

The user operates the client 100 to display the directory created as shown in FIG. 6 on the screen, and designate an arbitrary directory. When the directory is designated (S701), the document management unit 202
The corresponding search condition 206 is output to the search server 103 based on the specified directory (S702).

In describing this embodiment, it is assumed that the subdirectory "Traffic Accident" shown in FIG. 6 has been designated. Therefore, the document management unit 202
As the search condition 206, a search formula, a search sentence, a set of keywords, or a document for illustration relating to “traffic accident” associated in advance is output.

The search server 103 is connected to the client 100
, And the natural language processing module 300 analyzes the search condition 206 (S70).
3). Specifically, syntax analysis processing such as morphological analysis and dependency is performed using the dictionary 301 and the grammar dictionary 302.

Then, the natural language processing module 300
Extracts a noun phrase corresponding to the index word in the transposed file 102 from the search condition 206 based on the analysis result in step S703, and generates a document set 303 including the noun phrase (S704).

Subsequently, the query build component 305 inputs the document set 303 from the natural language processing module 300, and for each noun phrase constituting the input document set 303, the appearance frequency in the search condition 206, Statistical information such as distribution in the entire document DB 101 is obtained, and a query document 306 is generated by converting the document set 303 into a vector expression using the obtained statistical information (S705).

The search engine 307 inputs the query document 306 generated by the query build component 305, compares the vector of each document in the transposed file 102 with the vector of the query document 306, and A score corresponding to the degree of similarity is given to each document (S706).

The score according to the similarity expresses the similarity between each document and the query document 306 based on the cosine distance. A document having a higher score is more similar to the query document 306. It represents that it is.

The search engine 307 selects a document having a score exceeding the threshold based on a preset score threshold, generates a document list 308 based on the selected document, and performs a search. The result is output (S707).

FIG. 8 is an explanatory diagram showing an example of the document list 308. As shown in FIG. 8, in the document list 308, ranking of scores, document names, and the like according to the similarity with the query document 306 are displayed.

The client 100 operates as the search engine 30
7, the document list 308 is input, and based on the input document list 308, the documents having the highest rankings are sequentially entered.
The document name is displayed on the screen in association with the corresponding directory (S708). Therefore, the documents can be displayed in order from the document closest to the search condition 206 associated with the directory, and the criteria for the user to select the document can be provided.

FIG. 9 is an explanatory diagram showing an example of a state in which a list of document names is displayed in association with a specified directory. As shown in FIG. 9, a document corresponding to the sub-directory "traffic accident" specified in step S701 is searched from the document DB 101 by the search server 103, and the document name is displayed on the screen. In the state shown in FIG. 9, if a subdirectory “personal accident” under the subordinate directory is designated, an article related to “traffic accident” and “personal accident”
Will be searched and displayed on the screen.

Although the document names are displayed in accordance with the similarity here, the document names may be displayed in the order of date, Japanese syllabary or the like.

As described above, according to the document management support apparatus of the present embodiment, a directory is created independently of a storage medium, documents corresponding to the created directory are collected by using a search technique, and classified and managed. In this way, the documents in the document DB 101 can be read as if the documents in the document DB 101 had been classified into a plurality of directories in advance.
Documents inside can be classified and displayed.

Further, since the operation itself of the user is the same as that of a normal document management support device that manages a document in a directory, the user can retrieve the document without being conscious of searching for and displaying the document. Can be categorized and managed.

In the present embodiment, the document to be managed is a document in the document DB 101. However, if a plurality of document DBs are prepared, any It may be possible to select whether to target the DB. Regardless of which document DB is selected, document management is performed based on the directory set by the user.
, And similar document classification and management can be performed. Therefore, regardless of whether a database storing newspaper articles in 1996 or a database storing newspaper articles in 1995 is selected, classification and management of newspaper articles can be performed in the same directory. Further, even if the document DB is completely replaced with another one, it is possible to classify and manage the documents in the new document DB using the directory created in advance without creating a new directory. it can.

Further, a directory is created independently of the document DB 101, and documents corresponding to the created directory can be collected, classified, and managed using a search technique. This eliminates the need to classify and manage.
Therefore, when a document is newly stored in the document DB 101, it is not necessary to specify a storage destination directory.

Further, a directory is created independently of the document DB 101, and documents corresponding to the created directory can be collected, classified, and managed by using a search technique. Can be eliminated. Therefore, it is possible to prevent a situation where reading of a document becomes impossible when a file related to a directory is damaged.

Documents that correspond to some of the directories created by the user are displayed in all corresponding directories by the search by the search server 103.

Further, among the documents displayed in each directory, for the documents that the user considers appropriate or unsuitable as the classification result, the results can be fed back to the search server 103. That is, the user can specify a positive weight, for example, “+” for a document that is considered appropriate as a classification result, and a negative weight, for example, “−” for a document that is not appropriate as a search result. Can be specified. As a result, when the input weight is a positive specification, the weight of the corresponding document in the transposed file 102 is strengthened, and when the input weight is a negative specification, the weight of the document is weakened.

Further, in the present embodiment, the search by the vector space method has been described as an example, but the search processing may be performed by a Boolean search.

Although a detailed description is omitted in the present embodiment, processing such as deleting a document displayed as shown in FIG. 9 can be freely performed.

When associating the search condition with the created directory, the search condition created by the user may be associated with the directory, or a related word may be extracted from the document DB 101 and the extracted related word may be associated with the directory. May be.

Although a detailed description is omitted, it is clear that the document management support apparatus of the present embodiment can be applied to reading a document by an application program such as a word processor.

Further, the document management support device described in the present embodiment is realized by executing a prepared program on a computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a floppy disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. In addition, this program, via the recording medium,
Or it can be distributed over a network.
