Problems solved by technology

[0003] At present, the similarity between POIs is usually calculated according to the similar matching scheme of POI names in terms of text. Considering the poor naming standardization of POI names, it is difficult to accurately obtain the similarity between POIs only through the textual correlation of names. , resulting in a high repetition rate of the merged POI data

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] Among them, the similarity between POIs refers to whether the POIs represented by POI data from different sources identify the same physical entity in the real world, such as the same building or hotel, and the same community is the same physical entity, even if POI data from different sources The name, address, coordinates, etc. of the restaurant are not exactly the same, but in different buildings, the building and the restaurant in the building are not the...

Abstract

An embodiment of the present invention provides a data processing method, device, and server, wherein the method includes: acquiring feature information of a first point of interest POI and feature information of a second POI; Two feature information of the POI, matching the target feature on the first POI and the second POI to obtain a matching result on the target feature, the target feature includes a name feature, an address feature and a location feature; according to The matching result determines a degree of similarity between the first POI and the second POI. The similarity between POIs can be accurately determined through the embodiments of the present invention.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a data processing method, device and server. Background technique [0002] With the continuous advancement of science and technology, massive data on the Internet are generated, such as Point of Interest (POI) in navigation electronic maps, and POI is a landmark in Geographic Information System (GIS). Since there are many ways to obtain POI data, such as on-site collection, third-party purchase, web crawling, etc., different sources have different data formats and text descriptions, so it is very likely that there are POI data from different sources describing the same POI There are differences, resulting in the storage of multiple pieces of POI data for the same POI in the electronic map database, which requires calculating the similarity between POIs, and then judging the weight of POIs to merge the same POIs. [0003] At present, the similarity between POIs is us...
