Abstract

The invention relates to a POI name determination system based on clustering and a method thereof, wherein the method comprises the following steps: capturing address data from network data, the address data includes name field and address information; clustering name fields corresponding to the same address information according to key words; counting frequency of the clustered name fields occurred in each cluster, using the frequency as a second frequency; determining the POI name of the cluster corresponding to the address information based on the second frequency. By the provided technical scheme, users can quickly and precisely search the POI name corresponding to the POI address at the same longitude and latitude, thereby improving the user experience.

Description

technical field [0001] The present invention relates to the technical field of electronic maps, in particular to a cluster-based POI name determination system and a cluster-based POI name determination method. Background technique [0002] Point of Interest (POI) Geographic information points marked in general electronic maps usually include information such as POI identification, POI name, POI type, longitude, and latitude. POI can be marked on the map with latitude and longitude information, which can be used to find and calculate navigation landmarks or buildings, such as shopping malls, parking lots, schools, hospitals, hotels, restaurants, supermarkets, parks, tourist attractions, etc. [0003] More and more users are querying POIs in electronic maps, and the POI data stored in the database provides data support for POI queries. At present, updating the POI data in the database is mainly through actual data collection, updating the POI data stored in the database accor...
