Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document retrieval device for retrieving a desired document from a document database or the like.

[0002]

2. Description of the Related Art In recent years, with the spread of document databases and the improvement in processing capacity of electronic computers, document search apparatuses for searching for desired documents from a large number of document databases have come into wide use.

Particularly, in recent years, in order to improve flexibility in searching, a full-text search method has been used in which a user can freely specify a keyword without giving a search keyword to each document in advance. It has become to.

[0004]

By the way, when performing a search, a searcher, for example, "wants to find a place to travel".
Searching for travel guide books etc. for a specific purpose such as, but in this case, personal identification according to the searcher such as "where there is a hot spring" or "quiet place" It is common to search by considering the conditions of. In addition, since the purpose of the search changes if the field of search changes, generally, personal specific search conditions also change according to the field.

However, in the conventional full-text search type document search device, it is necessary to input / specify personal specific search conditions each time the search is performed. In addition, if the user does not enter or specify a specific personal search condition, the searcher needs to see even the extra search results that deviate from the desired search condition, and the desired search result cannot be obtained. I was spending time and effort.

The present invention has been made under such a background, and an object of the present invention is to provide a document search device capable of easily and quickly searching for a desired document.

[0007]

In order to achieve the above object, a document search device according to the present invention comprises a document storage means for storing a plurality of documents, and a personal search condition storage means for storing individual search conditions for each individual. An operator input means for inputting an operator, a document search condition input means for inputting document search conditions for searching a document, and the operation for the document search conditions input from the document search condition input means Personal search condition adding means for adding the personal search condition in the personal search condition storage means corresponding to the operator input by the person input means, and the document search condition to which the personal search condition is added by the personal search condition adding means And a search unit that searches the document storage unit for a document that satisfies the above condition.

[0008]

The document storage means stores a plurality of documents, and the individual search condition storage means stores individual search conditions for each individual. In such a situation, when the operator (operator name) is input by the operator input means and the document search condition for searching the document is input by the document search condition input means, the personal search condition addition means Adds the personal search condition in the personal search condition storage means corresponding to the operator input by the operator input means to the document search condition input from the document search condition input means.

Since the search means searches the document storage means for a document satisfying the document search condition to which the personal search condition adding means is automatically added by the personal search condition adding means, the desired document can be easily and quickly obtained. Will be searched.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the schematic arrangement of a document search apparatus according to an embodiment of the present invention. This document search apparatus includes a search condition input unit 1, a search condition analysis unit 2, and a personal search condition storage unit. 3, a personal search condition addition unit 4, a document database 5, a search processing unit 6, and a search result output unit 7.

The search condition input unit 1 is composed of, for example, a keyboard and the search result output unit 7 is composed of, for example, a printer, a liquid crystal display and the like. Also,
The search condition analysis unit 2, the individual search condition addition unit 4, and the search processing unit 6 are composed of, for example, a CPU, a ROM, and a RAM.
Using the RAM as a work area under the control of the CPU according to the program preset in the ROM,
Search condition analysis processing, personal search condition addition processing, search processing, etc. are executed. The personal search condition storage unit 3 is composed of, for example, a floppy disk or the like, and the document database 5 is constructed on a large-capacity memory such as a magnetic disk.

As shown in FIG. 2, the personal search condition storage unit 3 stores personal names such as "Taro" and search fields such as "travel" such as "hot spring" and "quiet". Personal search conditions are stored. It should be noted that the contents stored in the personal search condition storage unit 3 are preliminarily input by a keyboard or the like in this embodiment.

The search condition input unit 1 is used to input search conditions. The search condition also includes the searcher name and the search field. The search condition analysis unit 2
Based on the searcher name and search field analyzed by the search condition analysis unit 2, the personal search condition addition unit 4 analyzes the search condition input from the search condition input unit 1 and relates to the searcher name and search field. The personal search condition is extracted from the personal search condition storage unit 3 and added to the other search conditions analyzed by the search condition analysis unit 2.

The search processing unit 6 searches the document database 5 for a document corresponding to the search condition group to which the individual search condition adding unit 4 has added the individual search condition, and the search result output unit 7
Outputs the document searched by the search processing unit 6.

This document retrieval device is incorporated in a computer system, and in use, each operator (operator) declares and uses his or her own name (personal name) and retrieves it. Specify the field of and start the search.

Next, the search processing procedure will be described with reference to the flowchart of FIG. 3, taking as an example the case where the searcher "Taro" searches in the field of "travel".

First, the search condition input unit 1 inputs general search conditions indicating the purpose of the search (step S1).
For example, assume that "I want to see autumn leaves in Nagano prefecture" is entered as a general search condition. Then, the search condition analysis unit 2
This input content is analyzed and rewritten in a format suitable for performing the search process in step S7 described later, and the search condition "Nagano prefecture, autumn leaves" is set (step S2).

Then, the individual search condition adding unit 4 searches the individual search condition storage unit 3 for the individual search condition regarding the searcher "Taro" (step S3), and determines whether or not there is the individual search condition regarding "Taro". It is determined (step S4). As a result, if there is an individual search condition for "Taro", the search conditions for "Taro" in the "travel" field, that is, "hot spring" and "quiet" are read from the individual search condition storage unit 3 (step S5: FIG. 2), the read "hot spring" and "quiet" are added to the search condition "Nagano prefecture, autumn leaves" obtained by the search condition analysis unit 2 to set new search conditions (step S6).

Next, the search processing unit 6 searches the fields related to "travel" in the document database 5 with the search condition "Nagano prefecture, autumn colors, hot springs, quiet" including the added search condition as the search condition (step). S7). Then, the search result output unit 7 outputs the search result (step S8) and ends.

On the other hand, when there is no individual search condition for "Taro", steps S5 and S6 are skipped and the process proceeds to step S7. That is, the document database 5 is searched only by the search condition “Nagano prefecture, autumn leaves”.

As described above, the individual search conditions are registered in advance in the individual search condition storage unit 3, and the individual search conditions are automatically added to the general search conditions related to the input to search the document database 5. Therefore, the searcher can save the trouble of inputting a personal search condition that suits his / her preference each time the search is performed. Furthermore, if you register your own search conditions in advance, only the search results that match your taste will be output surely, and the search results that deviate from your taste will not be output. You can get it easily and quickly.

[Application Modification of Embodiment] In the above embodiment, the personal search condition is designated for each field, but the personal search condition may be designated for other categories, for example, for each CD-ROM. Good. Further, in the above embodiment, the personal search condition is always added to the search condition. However, in some cases, for example, when the search is conducted after receiving a travel consultation from a friend, the addition of the personal search condition may be inconvenient. Therefore, a changeover switch for switching between a mode in which the personal search condition is added and a mode in which the personal search condition is not added may be provided.

Further, in the above-mentioned embodiment, when the personal search condition for registration is added, the relevance to the general search condition for input is not checked. When "I want to go to see a festival" is input, "quiet" as the personal search condition and "lively" related to the input conflict. In order to avoid such inconvenience, check the semantic relevance between the personal search conditions related to registration and the search conditions related to input, and if there is a contradiction, consider the input related to the personal search conditions related to registration The search condition may be prioritized to determine the search condition.

Further, it is also possible to freely change the personal search condition by providing means for adding / deleting the personal search condition without fixedly registering the personal search condition.
In this case, for example, by automatically registering general search conditions that were input several times as general search conditions for the same searcher as individual search conditions, the individual search conditions are automatically learned through learning. It may be additionally registered. Further, the personal search conditions may be automatically registered by the above learning without performing any registration operation.

[0026]

As described above, according to the document retrieval apparatus of the present invention, the document retrieval conditions for retrieving a document are input by the document retrieval condition input means, and the operator is input by the operator input means. Then, the personal search condition adding means causes the personal search conditions in the personal search condition storage means corresponding to the operator input by the operator input means to be different from the document search conditions input from the document search condition input means. Since the added document is searched by the search means from the document storage means for the document satisfying the document search condition to which the search personal search condition is added, it is possible to save the trouble of inputting the personal search condition each time the search is carried out, and more surely. Only the search results that match your taste will be output, and the search results that do not match your taste will not be output, so you can easily and quickly search for the desired document.
