Embodiment 1

[0020] This embodiment provides a method for obtaining point of interest information, such as figure 1 shown, including the following steps:

[0021] Step 11, obtaining the input information of the point of interest.

[0022] Point-of-interest input information may be obtained through an input device. The POI input information may be the correct POI name, or a partially correct POI name, or other information related to the POI. This application uses the POI name as an example for illustration.

[0023] Step 12. Use the first fuzzy query method to determine the point of interest information according to the input information of the point of interest and the thesaurus, the thesaurus including the fuzzy thesaurus.

[0024] The first fuzzy query method specifically includes: segmenting the input information of the points of interest; querying the fuzzy thesaurus according to each segmentation result; determining the information of the points of interest according to the query re...

Embodiment 2

[0060] Such as image 3 As shown, the present embodiment provides an apparatus 30 for obtaining point of interest information, including: an obtaining unit 31, configured to obtain input information of a point of interest; a determining unit 33, configured to use a first The fuzzy query method determines the point of interest information, and the thesaurus includes a fuzzy thesaurus; the navigation unit 34 is used to navigate according to the point of interest information; the judging unit 32 is used to judge whether the query using the point of interest input information fails, when the query fails , start the determination unit 33, otherwise, directly return the result and start the navigation unit 34; the thesaurus building unit 35 is used to build the thesaurus. The determining unit 33 specifically includes: a segmentation unit 331, which is used to segment the point-of-interest input information; a query unit 332, which is used to query the thesaurus according to each seg...

Abstract

The embodiment of the invention provides a method and a device for acquiring points of interest, capable of solving the problem of incapable of acquiring information of points of interest in the prior art. The method comprises the following steps: acquiring the input information of the points of interest; utilizing a first fuzzy query method to acquire the information of the points of interest inaccordance with the input information of the points of interest and a word bank which consists of a fuzzy word bank. The device comprises an acquiring unit and a determinate unit. Therefore, when Chinese name information to be retrieved is input, input errors may occur for a user, if some word in the name is mistakenly input to be a homophone or a similar word, or the input keyword in the name isan alias thereof, but required points of interest information may be retrieved as the fuzzy word bank is utilized, thereby increasing fault-tolerance mechanism of query and improving the success ratio for querying POI names.

Description

technical field [0001] The present invention relates to the field of geographic information systems, in particular to a method and device for acquiring point-of-interest information. Background technique [0002] During the navigation process, it is first necessary to determine POI (point of interest, point of interest in electronic map data) data, and then perform navigation based on the POI data. [0003] POI data is an important part of electronic map data, providing attribute information of many facilities closely related to people's lives, including communities, schools, hospitals, shopping malls, supermarkets, office buildings, restaurants, hotels, parking lots, etc. [0004] Due to the huge amount of POI data stored in the electronic map database, in order to realize the fast query of POI data, the prior art adopts the following technical means: [0005] Determine whether the POI name or the first letter of the POI pinyin entered by the user matches the POI name or t...
