Embodiment 1

[0024] This embodiment provides a method for obtaining point of interest information, such as figure 1 As shown, including the following steps:

[0025] The input information of the point of interest can be obtained through the input device. The point of interest input information can be a correct point of interest name, or a partially correct point of interest name, or other information related to a point of interest. This application takes the name of a point of interest as an example for description.

[0026] Step 12. Use the first fuzzy query method to determine interest point information according to the input information of the interest point and the vocabulary, and the vocabulary includes a fuzzy vocabulary.

[0027] The first fuzzy query method specifically includes: segmenting the input information of interest points; querying the fuzzy vocabulary according to each segmentation result; determining the interest point information according to the query result, for example, ob...

Embodiment 2

[0062] Such as image 3 As shown, this embodiment provides a device 30 for obtaining point of interest information, including: an obtaining unit 31, configured to obtain input information of points of interest; and a determining unit 33, configured to use the first The fuzzy query method determines the point of interest information, the vocabulary includes a fuzzy vocabulary; the navigation unit 34 is used to navigate according to the point of interest information; the judging unit 32 is used to determine whether the query using the point of interest input information fails, and when the query fails , Start the determination unit 33, otherwise, directly return the result and start the navigation unit 34; the thesaurus establishment unit 35 is used to establish the thesaurus. The determining unit 33 specifically includes: a segmentation unit 331, configured to segment the input information of interest points; a query unit 332, configured to query the vocabulary according to each ...

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 priorart. 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 ratiofor 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...
