Abstract

PURPOSE:To guide telephone directory records close to a fixed number by retrieving a telephone directory after deciding an area so that the number of telephone directory records can be more than the number decided in advance while utilizing statistical information to control the number of the telephone directory records for each occupation for the unit of a mesh. CONSTITUTION:An input part 1, storage device part 2, work memory 3, display part 4 and control part 5 to be connected to the display part 4 are provided. When the name of the occupation and the name of an object are inputted, the control part 5 calculates the coordinates of the object from the data base of the storage device part 2 and investigates the number of the telephone directory records for the occupation corresponding to the inputted name of the occupation in respect to the mesh including the calculated coordinates of the object. Then, when the number of records does not each a prescribed number, the area is successively enlarged until the number of the telephone directory records reaches the prescribed number, and the retrieving area is decided. According to the decided area and the designated occupation, a telephone directory data base is retrieved and displayed. Thus, the telephone directory records, which number is closed to the fixed number, are retrieved corresponding to the inputted occupation and the almost same number of telephone directory solutions can be always guided.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention obtains a telephone directory solution within a predetermined area from a telephone directory database using occupation and target object as search conditions, and provides information guidance such as a town guide. Concerning a telephone directory search system that can provide services.

(Prior Art) A telephone directory search system is a system that displays the location and telephone number of a target object in a predetermined area on a display by inputting the name of the target object and the name of the occupation. In this telephone directory search system, it is necessary to accurately search for targets in a predetermined area according to input conditions.

FIG. 4 shows an example of the conventional configuration of this telephone directory search system. As shown in Figure 4, this type of system:
An input unit 41 for inputting search conditions for a telephone directory database, a storage unit 42 that accommodates a search object database 421 and a telephone directory database 422, and a work memory (3) that temporarily stores search results, etc. and a display unit 44 for displaying search results, and data exchange between the input unit 41, storage unit 42, work memory (3), and display unit 44 is controlled by a control unit 45 connected to these units. The target object database 421 is composed of items such as target object name, coordinate information, etc.
Further, the telephone directory database 422 is composed of items such as name, address, telephone number, occupation name, and coordinate information. usually,
This telephone directory search system was implemented on personal computers, workstations, and the like.

Next, the control section 45 in the conventional system shown in FIG.
The processing operation will be explained using the flowchart of FIG.

Steps 501 and 502 are a condition input process, and when a target object name and an occupation name are input from the input section 41 in step 501, the input conditions are inputted in step 50.
2, the data is stored in a predetermined portion of the work memory (3).

Next, steps 503 and 504 are performed as a target object search process. In step 503, the target object database 421 of the storage unit 42 is searched using the target object name as a search condition.
is searched, and the coordinates of the target object are stored in the work memory 43 in step 504. Subsequently, in step 505, which is performed as a region determination process, the coordinates of the target object are retrieved from the work memory Tsukuda, and a fixed-sized region centered on the coordinates of the target object is determined as a region condition for searching the telephone directory database 422. Ru. The determined area conditions are stored in the work memory in a predetermined format, for example, in the form of the coordinates of the lower left point and upper right point on the map of this area. Step 506 is a telephone directory search process in which the telephone directory database 422 is searched based on the occupation name and area information retrieved from the work memory 43, and the search results are stored in the work memory 43. The final step 507 is a solution display process,
The display section 44 displays the telephone directory information (the result of searching the telephone directory under certain conditions, the contents of which are the name, address, and telephone number), which is information on the search results of the telephone directory stored in the work memory 43. will be displayed.

Through the above-described process, conventionally, when a target object name or an occupation name is inputted from the input section 41, a telephone directory information such as the name, address, telephone number, etc. is displayed on the display section 44.

(Problem to be Solved by the Invention) However, in the conventional telephone directory search system, regardless of the geographical location conditions when searching the telephone directory database 422, the search area is set to a fixed area centered on the target object. As a result, depending on the location, it may not be possible to obtain telephone directory records for specified occupations in the area.
As a result, there is a problem in that even if there is telephone directory data for a designated occupation at a location that is geographically a little further away from the designated target, guidance cannot be provided.

On the other hand, if the range of the fixed area centered around the target object is set wide, there is a problem that the number of telephone directory records that match the conditions becomes too large and the time required to search the telephone directory database becomes long.

This invention aims to solve the problems of the prior art described above, and its purpose is to maintain a fixed number of telephone directory records corresponding to the inputted occupation, regardless of the geographical distribution of the number of telephone directory records for each occupation. To provide a telephone directory search system capable of searching for nearby telephone directory records and always presenting approximately the same number of telephone directory solutions.
