Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database system having a keyword candidate extraction function.

[0002]

2. Description of the Related Art In general, it is very important for a database not only to store a large amount of data but also to immediately retrieve the necessary data when needed. For this reason,
When inputting data to the database, keywords are registered to improve search efficiency.

In the conventional database system, in order to register a keyword, a first method in which an operator or a user inputs each keyword to be registered,
There has been a second method of selecting what is considered necessary from a keyword list and the like, and a third method of automatically extracting keywords from the subject or outline in the data to be input to the database. By using these methods, keywords necessary for search can be registered. Especially the third
The method of was convenient because the keywords were automatically extracted from the input data.

[0004]

However, the operator or the user must enter each keyword as described above
In the first method of inputting one by one and the second method of selecting a necessary keyword from the keyword list or the like, there is a risk of omission of selection. Further, in the third method of automatically extracting the keywords from the input data, the keywords other than the words existing in the input data cannot be registered.

Therefore, in the conventional database system, it is difficult to select keywords without excess or deficiency even if the above-mentioned first to third methods are used in combination. There were problems such as forgetting to select related words and losing uniformity in keywords. In this case, since the search efficiency is lowered, it has been required to select the keywords without excess or deficiency.

The present invention has been made in view of the above circumstances, and an object thereof is to register a keyword group related to the keyword in addition to the keyword when the keyword is extracted from the data input to the database. It is to provide a database system with a keyword candidate extraction function that can be automatically extracted as keyword candidates.

[0007]

SUMMARY OF THE INVENTION The present invention provides a keyword management means for managing and registering a keyword group for each group, an input information processing means for extracting keyword candidates from data input to a database, and this input. When the keyword extracted by the information processing means is registered in the keyword management means, in addition to the keyword,
A keyword candidate extracting means for extracting all other keywords belonging to the same group as the keyword as keyword candidates is provided, and the keyword candidates extracted by this keyword candidate extracting means are registered in the database in correspondence with the input data. The feature is that the power keywords can be selected.

Further, according to the present invention, when the keyword extracted by the input information processing means is not registered in the keyword management means, the group designation means for designating the group to which the keyword belongs and the keyword designation means It is characterized by further comprising keyword registration means for registering with the keyword management means so as to belong to the group.

[0009]

In the above configuration, when the data to be registered in the database is input, the input information processing means
Keyword candidates are extracted from the input data. If the extracted keyword is already registered in the keyword management means, the keyword candidate extraction means extracts all other keywords belonging to the same group as the keyword as keyword candidates, in addition to the keyword. Then, a keyword to be registered in the database is selected corresponding to the input data from the keyword candidates extracted by the keyword candidate extracting means.

On the other hand, when the keyword extracted by the input information processing means is not registered in the keyword management means, the keyword registration means causes the keyword to belong to the group designated by the group designation means. Register in the keyword management means.

1 is a block diagram showing the configuration of a database system with a keyword candidate extracting function according to an embodiment of the present invention.

In the figure, 10 is a database file, and 11 is a keyword management unit provided in the database file 10. This keyword management unit 11
It is for managing and registering a keyword group for each group. For example, when keywords such as “computer”, “personal computer”, “data processing device”, and “information processing device” related to computers are registered, these are the same group (group with group name “computer”). Be managed as belonging to.

Reference numeral 20 denotes an input / output device used for inputting data to be registered in the database file 10 and displaying / outputting keyword candidates. Reference numeral 30 denotes data / keyword registration in the database file 10 in accordance with an instruction input from the input / output device 20. This is a database management system (hereinafter referred to as DBMS) that controls processing, data search processing for the database file 10, and the like.

The DBMS 30 includes an input information processing section 31 for extracting keyword candidates from registration target data input to the database file 10 by the input / output device 20.
The keyword processing unit 32 is included.

When the keyword extracted by the input information processing unit 31 is registered in the keyword management unit 11, the keyword processing unit 32 includes not only the keyword but also all other keywords belonging to the same group as the keyword. A keyword candidate extraction unit 321 that extracts a keyword candidate, and a keyword selection unit 32 that selects a keyword specified by the input / output device 20 from the keyword candidates extracted by the keyword candidate extraction unit 321.
2 and a keyword registration unit 323. The keyword registration unit 323 registers the keywords extracted by the input information processing unit 31 in the keyword management unit 11 so as to belong to the group designated by the input / output device 20.

Next, the operation of the configuration of FIG. 1 will be described with reference to the flowchart of FIG. First, when registering data in the database file 10, the data registrant (operator or user) uses the input / output device 20 to perform an input operation for accurately inputting necessary data. The data input from the input / output device 20 by this input operation is taken into the input information processing unit 31 in the DBMS 30 and temporarily held in the processing unit 31.

When the data registrant operates the input / output device 20 to request a keyword input, the input information processing unit 3
1 extracts each word from the internally stored input data as a keyword candidate (step S1). Next, the input information processing section 31 uses the extracted keyword candidates as the input / output device 2.
The display is output to 0, and the designation from the input / output device 20 as to whether or not to register each as a keyword is sequentially accepted (step S2).

If there is a keyword candidate designated as a keyword, the input information processing section 31 sends the keyword to the keyword candidate extracting section 321 in the keyword processing section 32 and passes control to the extracting section 321. The keyword candidate extraction unit 321 searches the keyword management unit 11 using the keyword sent from the input information processing unit 31 (step S3), and checks whether or not a keyword matching the keyword has already been registered (step S3). S
4).

If a keyword matching the designated keyword has been registered, the keyword candidate extraction unit 3
21 extracts not only the keyword but also all other keywords registered in the keyword management unit 11 as belonging to the same group as the keyword (step S5). Then, the keyword candidate extraction unit 321 sends the extracted keyword candidates of the same group to the keyword selection unit 322, and the same selection unit 32
Pass control to 2.

The keyword selection unit 322 outputs the keyword candidates sent from the keyword candidate extraction unit 321 to the input / output device 20 for display. The data registrant is the input / output device 2
The operation to select and specify the required keyword from the keyword candidates belonging to the same group displayed in 0,
This is performed using the input / output device 20. In response to this, the keyword selection unit 322 selects all the keywords designated by the input / output device 20 from the keyword candidates of the same group displayed on the screen (step S6). Then, the keyword selecting unit 322 sends all the selected keywords to the input information processing unit 31, and passes control to the processing unit 31.

On the other hand, when it is determined in step S4 that the keyword matching the designated keyword is not registered in the keyword managing unit 11, the keyword candidate extracting unit 321 sets the keyword in the keyword registering unit 32.
3 and passes control to the registration unit 323.

Then, the keyword registration unit 323 displays and outputs to the input / output device 20 a group list indicating the candidates of the registration destination group of the keyword sent from the keyword candidate extraction unit 321. The data registrant uses the input / output device 20 to perform an operation for selecting and designating a required registration destination group from the group list displayed on the input / output device 20.
If the necessary group does not exist in the group list, the data registrant directly specifies and inputs the group name using the input / output device 20.

In response to this, the keyword registration unit 323 receives the group designation from the input / output device 20 (step S7). Then, the keyword registration unit 323 registers the keyword sent from the keyword candidate extraction unit 321 in the keyword management unit 11 so that it belongs to the designated group (step S8), and notifies the keyword candidate extraction unit 321 of the group name. Then, the control is returned to the extraction unit 321.

Then, the keyword candidate extraction unit 321 extracts all the keywords belonging to the group from the keyword management unit 11 (step S5), and passes control to the keyword selection unit 322. In this case, the keyword selection unit 3
22 performs the above-mentioned selection process (step S6) for the keyword candidates extracted by the keyword candidate extraction unit 321 and, thereafter, the input information processing unit 31.
Pass control to.

When the input information processing section 31 receives control from the keyword selecting section 322, it first internally holds the keyword sent from the keyword selecting section 322 (step S9), and then inputs it first. It is determined whether or not designation of whether or not to register each keyword extracted from the data as a keyword is completed (step S10). If the input information processing unit 31 is not designated as a keyword in step S2, the input information processing unit 31 immediately makes the determination in step S10.

Here, if there is any keyword for which the above-mentioned designation has not been made, the input information processing section 31 returns to step S2 and accepts the above-mentioned designation for the remaining keyword. On the other hand, when all the above-mentioned designations for each keyword extracted from the input data are completed, the input information processing section 31 associates the internally held input data with the selected keyword, and creates a database file. Register in 10 (step S1
1). Although the extraction of keyword candidates has been described above, the present invention can also be applied to extraction of related data candidates.

[0027]

As described in detail above, according to the present invention,
If a keyword group is managed and registered in advance and a keyword candidate is extracted from the data input to the database, and the keyword is already registered as belonging to a certain group, the other keyword , All other keywords that belong to the same group as the keyword are also extracted as keyword candidates, so in addition to the keyword candidates extracted from the input data, all keyword candidates related to it can be automatically extracted. Never forget to select keywords.

Therefore, by selecting a keyword to be registered in the database in correspondence with the input data from among these automatically extracted keyword candidates, when searching for data, not the word in the search target data, but the word Even if a related word is given as a keyword, it is possible to surely retrieve the target data.
