JPH0736918A - Retrieval result display method - Google Patents

Abstract

PURPOSE:To provide the retrieval result display method for a data base system which can removes partiality due to the display order of retrieval conditions under the same conditions whose order can not be set. CONSTITUTION:This method has a step 12 wherein data corresponding to a retrieval key are retrieved in a data base 3 when the retrieval key is inputted from a terminal 1A, a step 13 wherein it is checked whether or not there is corresponding data, a step 14 wherein the corresponding data is outputted as a retrieval result to a buffer 4, a step 15 wherein it is decided that the retrieval result are under the same conditions whose order can not be set, a step 16 wherein the display order of retrieval results in the buffer 4 is changed by using a random number when the retrieval result under the same conditions whose order can not be set are decided, and a step 18 wherein the retrieval results are outputted to a terminal in display order after the change.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a search result display method in a database system.

[0002]

2. Description of the Related Art Conventionally, when a database system is searched for something, the search results are arranged in the order of a predetermined condition and output in the order of rank. However, if the search results are of the same condition in which the order cannot be set, the names are sorted by [alphabetical order] or [aiueo order], or are output by [data code order] built in the database.

[0003]

In the prior art, for example, when searching for a flower shop in a city using a database system,
Multiple store names corresponding to the search key called "florist" are listed in [alphabetical order] or [aiueo order]. However, the search order is fixed, even though the search result is the same condition that "Florist" cannot be ordered.
Store names starting with [A] or [A] are always attracting attention, while the store names in the latter half such as [Y] or [Wa] are always low in attention, causing injustice. In this way, it is not preferable that the display order causes unfairness with respect to inspection results under the same condition in which the order cannot be set, even though the same database registration fee is collected.

An object of the present invention is to solve the above problems and to provide a search result display method for a database system capable of eliminating unfairness due to the display order with respect to search results of the same condition whose order cannot be set. It is in.

[0005]

To achieve the above object, the present invention comprises the steps of receiving an input of a search key from a terminal, and searching the database for data corresponding to the received search key. , A step of temporarily storing the retrieved data as a retrieval result in a buffer,
A step of determining whether or not the search results are under the same condition that the order cannot be set, and a display of the search result in the buffer when it is determined that the search result is under the same condition that the order cannot be set It is characterized by including a step of changing the order using a random number generated by a random number generating means, and a step of outputting the search result to the terminal in the changed display order.

[0006]

In the search result display method of the present invention, when the search key is input from the terminal, the data corresponding to the search key is searched from the database and the corresponding data is output to the buffer as the search result. If it is determined that the same order cannot be set, the display order of the search results in the buffer is changed using random numbers, and the search results are output to the terminal in the changed display order. As a result, the unfairness due to the display order for the search results under the same condition in which the order cannot be set is removed, and the fairness of the profit of the information source who paid the same database registration fee is guaranteed.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a schematic configuration of a database system for executing a search result display method according to an embodiment of the present invention. In FIG. 1, 1A, 1B and 1C are terminals used for input / output respectively, 2 is a CPU for management control of a database system, (central processing unit), 3
Is a database for storing various information, 4 is a buffer for temporarily storing search results, and is used for a plurality of terminals 1A, 1B, 1
C is connected to the CPU 2.

FIG. 2 shows a processing procedure of a search result display method according to an embodiment of the present invention. First, when the user A searches for something using the database, the user A inputs a search key from one of the plurality of terminals, for example, the terminal 1A. The CPU 2 receives the input of the search key from the terminal 1A (step 11), searches the database 3 (step 12), and checks whether or not there is an item corresponding to the search key (step 13). If there are applicable items,
The search result of the corresponding data in the database is output to the buffer 4 for temporary storage (step 14).

Next, the CPU 2 determines whether or not the search result data in the buffer 4 has the same condition that the order cannot be set for any other search result data (step 15). When it is determined that the search results have the same condition in which the order cannot be set, the order of the search result data stored in the buffer 4 is shuffled by using a random number to change the display order (step 16). . The search results are output to the terminal 1A in the display order after the change (step 18). In this way, it is possible to solve the unfairness due to the display order of the search results of the same condition in which the order cannot be set.

Other points in the processing sequence of the embodiment of the present invention are as follows. That is, step 1
Since the search method of 2 is outside the scope of the present invention, its detailed description is omitted. When it is determined in step 13 that there is no corresponding item, this process ends. In step 15,
When it is determined that the search result data in the buffer 4 has a difference in the order of satisfying a predetermined condition and the order setting is possible, the order of the search result data stored in the buffer 4 is changed. The display order is changed by sorting the order (step 17). The algorithm for sorting the display order of the search result data in step 17 in the order of rank is out of the scope of the present invention, and thus its detailed description is omitted.

FIG. 3 shows an example of the data structure of the search result data stored in the buffer 4. Thus, in the data structure, the index <item 1> indicating the output order in step 14 and the data content <item 2 corresponding to item 1 are included.
> And a random number value <item 3> to be used for sorting later is provided as an array area. It is assumed that at the start of step 16, only the data relating to item 1 and item 2 are set and item 3 is blank.

FIG. 4 shows details of the display order changing algorithm using random numbers in step 16 of FIG.

First, it is assumed that the initial value of the variable n is 1. A random number corresponding to the nth data item 1 is generated using a random number generator (step 21), and the generated random number is set as the nth data item 3 (step 2).
2). Next, it is judged whether or not there is an unset area in item 3 (step 23), and if there is an unset area, the variable n is incremented by 1 and the process is returned to step 21. Then, the above processing is repeated for the total number of search result data stored in the buffer 4. When there is no unset area in item 3, the random number values of item 3 are sorted in ascending or descending order to change the order of the search result data stored in the buffer 4 (step 24).

[0015]

As described above, according to the present invention,
If the search results in the database system have the same condition that the order cannot be set, the search results are displayed by randomly rearranging the display order using a random number generated by a random number generator. There is an effect that the unfairness due to the display order for the search results of the same condition that cannot be set is removed, and the fairness of the profit of the information source who paid the same database registration fee can be guaranteed.
