JPH05324437A - Keyword retrieving system for data base - Google Patents

Abstract

PURPOSE:To simplify a describing method and to easily perform setting even in the case of a complicated retrieval expression by inputting a desired keyword to a keyword input area, linking it with another card as needed and deciding a search condition. CONSTITUTION:A keyboard inputs the keyword to an area 18 of a card 16 displayed as a window. When there is any keyword to be further inputted and the retrieval condition is 'AND', the keyword is inputted to an area 20 or when the retrieval condition is 'OR', it is inputted to an area 22. Concerning the other card, the keyword is similarly set as well, and a series of retrieval expressions can be set by linking these cards on the inter-card retrieval condition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyword search system for a database, and in particular, a plurality of keywords can be "ANDed" by a personal computer or a workstation.
The present invention relates to a keyword search method for a database, which is searched by combining search conditions such as "OR".

[0002]

2. Description of the Related Art Conventionally, for example, a search expression is directly written as shown in FIG. 9, or a search expression written with a keyword and a symbol corresponding to it is input as shown in FIG. A method of describing only keywords in a fixed one has been proposed.

[0003]

In the method of [Problem to be Solved by the Invention], the method of describing a search expression becomes complicated, and in the case of a complicated search expression, it becomes difficult to interpret the expression for searching. In the method of
In the case of a complicated search expression, it is difficult to interpret the expression for searching. The method of (1) has a problem that a complicated search expression using parentheses "()" cannot be described and only a fixed expression can be described.

Therefore, a main object of the present invention is to provide a keyword search system for a database, which has a simple description method and a complicated search formula can be set easily.

[0005]

According to the present invention, a card having at least one fixed search condition and a keyword input area associated therewith is displayed on a display means, and a desired keyword is input to the keyword input area to make it necessary. It is a database keyword search method that determines the search condition by combining with another card according to the method.

[0006]

[Operation] For example, "AND" or "OR" is added to the card in advance.
A search condition such as is fixedly described, and a simple search formula is set only by inputting a keyword in the keyword input area. In addition, if such cards are connected by a search condition of "AND" or "OR", a complicated search formula is set.

[0007]

According to the present invention, basically, it is only necessary to input the keyword in the keyword input area of the card, so the description method is simple, and the search condition is set between the cards as required. By doing so, you can easily set complicated search expressions. The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The keyword search method of this embodiment is a card type search expression input method using a window type user interface environment, and is applied to the search device 10 shown in FIG. The search device 10 includes a search processing unit 12 including a CPU and the like, and the search processing unit 12 includes a display device 1 such as a CRT that displays a card when a search expression is input and a search result.
4 is connected. A window is displayed on the display device 14, and a card 16 as shown in FIG. 2 is displayed on the window. The card 16 includes areas 18, 20 and 22 for inputting keywords to be searched. In the area 18, the reference keyword is input and the search condition is "A.
If the search condition is “OR”, the keyword is input to the region 20, and if the search condition is “OR”, the keyword is input to the region 22. Further, if the “AND” search condition continues, the keyword input area is expanded vertically, while if the “OR” search condition continues, the keyword input area is expanded horizontally.

In this embodiment, one card 16
For, only one of the search conditions of "AND" and "OR" can be selected. Further, the card 16 includes an AND key area 24 and an OR key area 26, and the AND key area 24 is an inter-card search condition setting area for creating another card having an “AND” relationship with this card 16, The OR key area 26 is an inter-card search condition setting area for creating another card having an “OR” relationship with this card 16.

Further, the search processing unit 12 is connected to an external storage device 28 for storing document files forming a database of indexes and documents. The search processing unit 12 has a keyboard 30 for inputting keywords and a mouse 3 for facilitating card operation.
2 is connected to the card 1 by operating the keyboard 30, mouse 32 or touch pen (not shown).
6. Input a desired keyword in the areas 18, 20 and 22 of 6, and AND key area 24 or OR key area 2
Select 6 to set inter-card search conditions.

First, the general operation will be described with reference to FIGS. 3 and 4. In step S1, one basic card 16 is prepared. In step S3, the reference keyword is set in the area 18 in the basic card 16.
To enter. In step S5, it is determined whether or not there is a keyword to be input. If there is a keyword to be input, the search condition is "AND" in step S7.
Or "OR". If the search condition is "AND", a keyword is input to the AND area 20 in step S9, and it is determined in step S11 whether or not there is a keyword to be further input. If there is a keyword to be input, the card 16 is expanded in the AND direction in step S13 to create an input area, and the keyword is input again in the AND area 20 in step S9.

On the other hand, when the search condition is "OR" in step S7, OR is executed in step S15.
The keyword is input to the area 22 of No. 22 and it is determined in step S17 whether there is a keyword to be further input. If there is a keyword to be input, the card 16 is expanded in the OR direction to create an input area in step S19, and the keyword is input again in the OR area 22 in step S15.

If there is no other keyword to be input in steps S11 and S17, or if there is no other keyword to be input in step S5, the process proceeds to step S21 shown in FIG. To judge. In the case of further conditioning, the process proceeds to step S23 and the condition between the cards 16 is “AN
The condition between the cards 16 is AN by judging whether it is “D” or “OR”.
If it is D, in step S25, the AND key area 24 is selected to prepare one new card, and the process returns to step S3. If the condition between the cards 16 is OR in step S23, the OR key area 26 is selected in step S27, and a new card is added.
The sheets are prepared, the process returns to step S3, and the above-described processing is repeated.

In step S21, if the condition is not further conditioned by another card, the input ends. Here, the search operation based on the specific cards 16a and 16b shown in FIG. 5 will be specifically described with reference to FIGS. First, the basic card 1 in step S29
Prepare 6a. Then, in step S31, the reference keyword "information" is input to the area 18a in the basic card 16a as shown in FIG. In step S33, it is determined whether there is a keyword to be further input. In the case of this example, since there is a keyword to be input and there is a search condition, the keyword "database" is input to the AND area 20a in step S37 through step S35. Then, since there is a keyword to be further input, in step S41 shown in FIG. 7 through step S39, the card 16a is expanded in the AND direction to create an AND area 34a. Step S43
In the AND area 34a, the search keyword "SANYO"
Is input, and it is determined in step S45 whether or not there is a keyword to be input. In the case of this example, since there is no keyword to be input, the process proceeds to step S47. In this example, since the search condition between the cards 16a and 16b is "AND", the AND key area 24a is selected in step S51 through step S49 to prepare a new card 16b. Then, "AND", which is the inter-card search condition, is displayed on the upper right of the card 16a and the upper left of the card 16b, respectively.

Then, in step S53, the reference keyword "artificial intelligence" in the new card 16b is input to the area 18b. In the case of this example, since another keyword “AI” is combined by OR, step S55 and step S57 shown in FIG.
At 59, the keyword "AI" is input to the OR area 22b, and it is determined at step S61 whether or not there is a keyword to be further input. Since there is no keyword to be input, the input ends.

In this way, the search expression "information" AND "database" AND "Sanyo" is written on the card 16a, and "artificial intelligence" OR "A" is written on the card 16b.
A search formula "I" is described. Then, by combining the cards 16a and 16b with "AND", ("information" AND "database" AND "Sanyo") AND
A search expression "(artificial intelligence) OR" AI ") is created.

According to this embodiment, one card includes
Simply enter a search expression that is combined with simple "AND" or "OR", and if necessary, combine another card with a search condition such as "AND" or "OR".
You can easily set up complex search expressions using. Further, a plurality of search expressions can be set by attaching a plurality of cards to a larger card and creating another card that is combined with the larger card by a search condition such as “AND” or “OR”. Also, during the search process,
The desired search is performed for each card, and the search results for each card are processed to satisfy the search conditions such as "AND" and "OR" between the cards, and the processing is performed up to higher search conditions. You can get the desired search result by repeating.
