Problems solved by technology

[0004] However, at some point, the user may only want to know the distance from the current location to a certain POI, so it needs to go through the above steps to know, or the user wants to refer to the distance from the current location to a certain POI before deciding whether to travel. To determine whether to travel or not after the distance, it also needs to go through the above steps to know. On the one hand, the operation is cumbersome, and on the other hand, it also wastes network traffic

Embodiment 1

[0036] figure 1 The flow chart of the search suggestion method for map search provided by Embodiment 1 of the present invention mainly includes two implementation stages in this embodiment: an offline stage and an online stage. In the offline stage, the establishment of the database used for providing search suggestions is mainly completed. In the embodiment of the present invention, because it is mainly used for map search, the database used is called POI index library; the online stage mainly completes the real-time capture of keywords input by users and provides search suggestions. see below figure 1 Describe these two stages in detail.

[0037] Such as figure 1 As shown, the offline phase is mainly step 101:

[0038] Step 101: According to the name of each POI, index is respectively established in the POI index library with the first N characters of each POI name, and the location information of each POI is recorded.

[0039] POI information is pre-collected. There is ...

Embodiment 2

[0063] image 3 It is a structural diagram of a search suggestion device for map search provided by Embodiment 2 of the present invention. The device is usually set up with a server end of a map search engine and interacts with a browser or a client terminal used by a user. The device is based on a pre-established POI index library, which records the coordinate positions of each POI, such as image 3 As shown, the device includes: an input acquisition unit 01 , an index table query unit 02 and a search suggestion unit 03 . It further includes: an index database building unit 04 , a positioning unit 05 and a distance calculation unit 06 .

[0064] Among them, the index building unit 04 completes the operations in the offline phase, and all other units complete the operations in the online phase.

[0065] Specifically, the index library building unit 04 is used to create a POI index library, and in the POI index library, the first N characters of each POI name are respectively...

Abstract

The invention provides a search recommending method and device for map searching. Point of interest (POI) position coordinates are recorded in a POI index database built in advance. The method includes that S1, a keyword currently input in a search box by a user is obtained; S2, the keyword is matched with an index in the POI index database, a POI name and a POI position coordinate corresponding to a matched index are determined; S3, searching advice is provided for the user by means of the determined POI name in the step 2, and distance between the POI position coordinate and the position coordinate where the user is located is provided in searching advice. When the user only wants to obtain the distance from the current position to a certain POI, or wants to obtain the distance between the current position to a certain POI as a reference before specific location or path planning, by means of the method and device, operation is simple, and network flow is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of computer applications, in particular to a search suggestion method and device for map search. 【Background technique】 [0002] With the rapid development of computer technology, search engines have become an important means for people to obtain information and have gradually penetrated into various fields. Map search is one of the fields that develop rapidly and are widely used. [0003] The current service items of map search mainly include: location query, bus query, line query, etc. For example, when a user wants to query the location of a certain point of interest (POI), the route to a certain POI, or the distance to a certain POI, the most common way is to first enter the name of the POI in the search box provided by the map application. Name, and then the map search engine can search for the specific location information of the POI on the map and mark it to the user. If the user wants to continue...
