Method, device and system for classifying POI information

Abstract

The invention provides a method and a device for classifying POI information. The method comprises the steps as follows: extracting name information of the POI information to be classified; performing word segmentation to the name information and obtaining a plurality of segmentation fragments; matching the plurality of segmentation fragments with a classification keyword according to a preset matching sequence; determining a POI classification directed by the classification keyword corresponding to the segmentation fragment which is matched successfully at first as a belonged classification of the POI information to be classified. The method and the device of the invention could reduce the time needed for performing the word segmentation because only the name information of the POI information to be classified needs to perform the word segmentation, and then perform keyword matching to the segmentation fragments obtained by performing the word segmentation so as to correspondingly reduce the matching times while performing the keyword matching afterwards based on fewer segmentation fragments obtained by performing the word segmentation and increase the run time of POI information classifying process. Simultaneously, the classification accuracy determined based on the name information is relative high because the name information and the POI information have high correlation, thereby improving efficiency of POI information classification as a whole.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, the present invention relates to a method and a device for classifying POI information. Background technique [0002] With the development of science and technology and the progress of society, geographical information services including electronic maps are increasingly popular with netizens due to their convenience, quickness and intuitive visualization, and are widely used in various fields of life. The demand for obtaining location-related information is becoming stronger and stronger, and location-related information may include hotels, airports, restaurants, banks, shopping malls, hospitals, parks, gas stations, etc. at a certain address. Entity information is called POI information. Because such POI information integrates geographic entity information and geographic location information, it can bring great convenience to users. In order to further improve the effi...

Problems solved by technology

[0004] The disadvantages of the existing POI information classification methods mainly include: on the one hand, because the content of the web page text is usually relatively long, it takes a long time to segment the web page text, and there are many segmentation fragments obtained after word segmentation, which makes The number of keyword matches is relatively large, so the overall classif
