Therefore, there may be repetitive data in the POI data obtained from different source websites, that is, multiple pieces of POI data actually describe the same POI, and their actual POI longitude and latitude are the same, but the POI name and POI address are described in different ways. different
Repetitive POI data makes it impossible for users to quickly and accurately search for the POI name corresponding to the POI address of the same POI geographic location (latitude and longitude), which affects user experience

The invention relates to a system and a method for confirming POI information effectiveness based on address data in network. The method for confirming the POI information effectiveness includes that using the address data in the network to acquire multiple related POI information corresponding to the same POI name; counting the occurrence number of the POI information in the address data of the network; confirming the effective POI information corresponding to the same POI name according to the occurrence number of the POI information in the address data of the network. The different modes of the same POI name are classified into the same cluster through keyword clustering, the best POI name is selected from a plurality of POI names corresponding to the same longitude and latitude through an Internet voting mechanism, the credible POI name is selected through the Internet voting mechanism, a user can quickly and precisely search the credible POI information corresponding to the same POI address, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of electronic maps, in particular to a system for determining the validity of POI information based on address data in a network and a method for determining the validity of POI information based on address data in a network. Background technique [0002] A point of interest (POI) is a geographical information point marked in an electronic map, and usually includes 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 ...
