Problems solved by technology

This processing is realized by acquiring information from a retrieval database each time a character is input, so that communication with a server device via a communication network occurs each time a character is input, especially a communication means such as a navigator is When a low-speed mobile communication device has to be used, the operability of the user is significantly deteriorated
[0013] In addition, the purpose of the technology described in Patent Document 3 is to first search the database stored in the navigator when performing data retrieval, and if the corresponding data does not exist in the database of the navigator, the input retrieval condition (category, telephone number, 50-sound name, etc.) are sent to the server device, and searched in the database of the server device, but this technology is based on the premise that no query to the database occurs while the user is inputting the search conditions
In contrast, the above-mentioned function of prompting the user for candidate names each time a character is input must inquire to the database every time a character is input, so it is difficult to implement in the technology described in Patent Document 3

Embodiment 1

[0058] Next, use Figure 1~Figure 16 The name candidate presentation type retrieval system of the first embodiment will be described. In addition, in Embodiment 1 and Embodiment 2, an example of a system for retrieving data by inputting a name in English characters is described, but the present invention is not limited to the use of English characters, as long as it is a system that presents candidates and retrieves names, it can also Applied to other languages ​​such as Japanese, German, French, or numbers (such as the phone number corresponding to its name).

[0059] In Embodiment 1, when the user searches for facility information, candidate facility names are displayed every time a character of the name is input, and when the user selects a candidate name, the search server device is asked for facility information, and the result is displayed on the screen.

Embodiment 2

[0098] Below, use Figure 17~Figure 20 The keyboard-controlled retrieval system of Embodiment 2 will be described. In Embodiment 2, when the user searches for facility information, each time a character of the name is input, the display of the corresponding number and the control that only the key corresponding to the character that can be input next can be pressed can be performed. When the search button is pressed, the search server device is asked for facility information, and the result is displayed on the screen.

[0099] Figure 17 A diagram showing the overall configuration of the keyboard-controlled retrieval system of the second embodiment. The basic structure is the same as that of Example 1, and the difference with Example 1 is that the figure 1 In the candidate name setting section 160, a keyboard control section 170 is newly added; and the change record is in figure 1 The structure of the retrieval tree data 141 in the retrieval tree data recording unit 140 is...

Abstract

A search terminal device, a search server device, a search tree compression method, and a center-cooperative search system reduce the size of a search database stored in a navigator without impairing user operability during search operations. The above-mentioned search terminal device is connected to the search server device via a communication network, and includes: a search tree data storage unit for storing search tree data, and the search tree data associates node information with entity identification information; an input control unit based on information input from the user Or lower-level information and node information stored in the search tree data storage unit, output as a candidate for the data of the search object; and the entity data acquisition unit sends a search request including entity identification information to the search server device, and obtains from the search server device Recognized entity data.

Description

technical field [0001] The present invention relates to a technique for reducing the size of search data. Background technique [0002] A car navigation system (hereinafter referred to as a navigator) processes map data to provide traffic guidance information to users. HDD (Hard Disk Drive: Hard Disk Drive) has been used as a recording unit for this map data in many models, but in recent years, models using semiconductor device memory such as SD memory card and SSD (Solid State Drive: Solid State Drive) have become mainstream. [0003] Compared with the conventional HDD, the semiconductor device memory has advantages such as low power consumption and excellent shock resistance, but has the disadvantage of high unit price per unit capacity. Therefore, in order to provide users with a navigator at the same price range as in the past, it is necessary to reduce the capacity of the memory of the semiconductor element used. On the other hand, the content of the data required fo...
