Abstract

PURPOSE:To realize an easy and dependable renewal of the keywords of all corresponding documents by performing the setting of the keyword when the document is registered with a numeral or a mark corresponding to the keyword of a keyword file. CONSTITUTION:An item table 1 is the keyboard file generated at every unit(item) to set the keyword, and a keyword registration control part 2 registers the keyword on the item table 1 according to input from a keyboard 8. And a retrieval part 4, upon performing the retrieval of the document stored in a document file 5, performs the retrieval based on the item number of the keyword of a registered document. When the keyword is changed, the item is displayed on a display part 7 first, and the keyword of corresponding number in a displayed item table is changed. Thereby, the simplification of the change of the keyword and that of the condition setting of the keyword retrieving can be attained.

Description

[Detailed Description of the Invention] [Summary] The purpose of the present invention is to provide a method for easily and reliably updating keywords with respect to a method for setting keywords in a database management system. In a database management system constructed as possible, a keyword file is provided with a means for registering keywords corresponding to different numbers or symbols, and a means for enabling the keyword to be changed to a different keyword. , means for setting keywords when registering a document using numbers or symbols corresponding to the keywords in the keyword file.

[Industrial Application Field] The present invention relates to a processing method for updating keywords on a database.

When a plurality of documents having the same keyword exist in the database and it becomes necessary to update the keyword, all existing keywords in the database must be updated.

The present invention relates to a keyword setting method that allows updating of such keywords easily and reliably.

[Prior Art] Conventionally, keywords for searching documents have been set for each document when each document is registered.

FIG. 3 is a diagram showing an example of such a document, in which (a)
-(f) indicate documents 1 to 6, respectively.

In such a document, for example, by specifying the company name=Electric Corporation as a keyword, (b), (C).
Documents 2 to 4 shown in (d) are searched.

If we consider that the name of the Telegraph and Telephone Public Corporation was changed to NTT and the monopoly public corporation was changed to Japan Tobacco, (b). (C
). Change the company name of documents 2 to 4 shown in (d) to NTT, and
It is necessary to change the company name in document 6 shown in (f) to Japan Tobacco.

After changing the company name like this, the company name=NT
You can get the correct search results using T or company name 2 Japan Tobacco Industries.

If the keyword is not changed at this time, it will not be possible to obtain correct results in subsequent searches.

[Problem to be solved by the invention] As mentioned above, conventionally, keywords were registered for each document at the time of document registration, so if the keywords needed to be changed, the corresponding keywords could be used to change the keywords. It was necessary to find all the documents containing keywords and change the keyword registration.

FIG. 4 is a flowchart showing an example of the procedure of such conventional keyword change processing.

That is, as shown in the figure, the operator displays the document keywords on the screen for each registered document, checks whether there is a keyword to be changed, and if there is a keyword to be changed, changes it. do. Then, such processing is performed for all registered documents.

This is a rather troublesome task, and because it relies on the operator's visual recognition of the presence or absence of the target keyword, there is a risk of overlooking the keyword that should be changed.

SUMMARY OF THE INVENTION In view of these conventional problems, it is an object of the present invention to provide a means for updating keywords of all applicable documents in a simple and reliable manner.

[Means for Solving the Problems] According to the present invention, the above objects are achieved by the means described in the claims.

That is, the present invention provides means for registering keywords in a keyword file so as to correspond to different numbers or symbols, in a database management system constructed so as to enable searching of files by keywords, and means for registering keywords in a keyword file so as to correspond to different numbers or symbols. This keyword setting method is provided with means for making changes possible, and means for setting keywords when registering a document using numbers or symbols corresponding to the keywords in the keyword file.

[Function] In the present invention, keywords used for searching are registered in a keyword file in association with different numbers or symbols, etc. for each keyword.On the other hand, when registering each document,
Since numbers, symbols, etc. corresponding to the keywords are registered as keywords, when changing keywords, only the registered contents of the keyword file need to be changed.

For example, if @1” → “Fuji×” is registered in the keyword file, if you perform a document search using the keyword “Fuji×”, documents registered in the file as company name = “1” will be retrieved. Ru.

To change this keyword to, for example, "Fuji x Co., Ltd.", the registration of "l" → "Fuji x" in the keyword file may be changed to "1" → "Fuji x Co., Ltd.".

At this time, there is no need to touch the registered keywords of each document.

From then on, the relevant documents are accurately searched using the keywords company name=Fuji x Co., Ltd.

[Example 1] FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, where l is an item table, 2 is a keyword registration control section, 3 is an item list succession section, 4 is a search control section, and 5 is a block diagram showing the configuration of an embodiment of the present invention. 6 represents a document file, 6 a display control section, 7 a display section, and 8 a keyboard.

In the figure, item table 1 is 1 unit for setting keywords (
A keyword file created for each item),
It exists separately from the target for which the keyword itself is set.

Further, in this item table 1, 999 keywords can be registered for one item.

The keyword registration control unit 2 registers keywords in the item table 1 according to manual input from the keyboard 8.

On the other hand, when registering a document, the corresponding document is registered in the document file 5, and the keyword registration control unit 2 registers the item number of the keyword registered in the item table 1 in the document.

When searching for documents stored in the document file 5, the search section 4 searches by the item number of the keyword of the registered document.

When changing a keyword, first an item list is displayed on the display section 7.

The item table is displayed by the item table succession section 3 reading out the corresponding item table in response to an operation from the keyboard 8, and the display control section 6 displaying it as an image on the display section 7.

Then, the keyword of the corresponding item number in the displayed item table is changed.

The above processing will be further explained below using an actual example.

FIG. 2 is a diagram illustrating an example of keyword setting according to the present invention, (a). (h) represents an item list, (b), (c). . . . (G) indicates documents 1 to 6, respectively. In the same figure,
It is assumed that the contents of the item table are set in advance as shown in (a).

Then, when registering the document, enter the keywords of documents 1 to 6 (
b) to (G).

In this state, the keyword "Company name = Electricity and Telecommunications Public Corporation" is used in document 2.
, document 3, and document 4 are retrieved.

Here, if you want to change the Telephone and Telecommunications Public Corporation to NTT and the monopoly public corporation to Japan Tobacco, you can display the item list on the display section 7 and make the changes as shown in (h).

At this time, there is no need to touch the registered contents of documents 1 to 6 shown in (b) to (G) at all.

By changing the keywords in the item list, documents 2 to 4 are searched for using the keyword "company name = NTTJ" and document 6 is searched for using the keyword "company name - Japan Tobacco Industry."

[Effects of the Invention] As explained above, according to the method of the present invention, it is possible to simplify keyword changes and to simplify keyword search condition settings in systems that perform keyword searches. This also eliminates the possibility of processing errors.

Therefore, in the case of a search item in which the name of the keyword changes, there is an advantage that changing the keyword by changing the name or adjusting the name can eliminate the complexity of setting conditional expressions at the time of search, and that accurate processing can be performed.
