Interest point data correlation method and device therefor

Abstract

The embodiment of the invention provides an interest point data correlation method and a device therefor. The method comprises the following steps: reading two batches of interest point data; grouping the interest point data to obtain grouping sets and grouping identification lists of the two batches of interest point data; respectively reading a group from the two grouping sets by the two grouping identification lists; establishing a hash table with the attribute of interest point data of a group being the keyword; matching the attribute of another group of interest point data with the keyword of the hash table to obtain two samely grouped interest point data. Correspondingly, the embodiment of the invention provides an interest point data correlation device. With the method or the device of the embodiment of the invention, repetitive data of different batches of POI data can be effectively correlated.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a point of interest data association method and device. Background technique [0002] At present, in the geographic information system (Geographic Information System, GIS), the collection methods of Point Of Interest (POI) data mainly include on-site collection, Internet collection and so on. When collecting POI data, the collector does not consider whether the POI data has already been collected, so there are many duplicate POI data among POI data collected in different batches. [0003] During the research and practice of the prior art, the inventors found some problems in the application of POI data due to the existence of repeated POI data. For example, in the electronic map service provided by a website, "Donglaishun" is used as the keyword to search for POI data related to it. Among the POI data query results displayed on the electronic map of the we...

Problems solved by technology

For example, in the electronic map service provided by a website, "Donglaishun" is used as the keyword to search for POI data related to it. Among the POI data query results displayed on the electronic map of the website, there are two "Donglaishun Xidan stores" in Xidan that are very close. " and "Donglaishun Restaurant", although the names of these two POI data are not exactly the same, but their addresses are both "Xidan Lingjing Hutong No. 23", these two POI data are duplicate data, such query results are easy to use User misunderstands

Therefore, the inventor believes that there is an urgent need to provide a technology that can associate the same POI data together, so as to effectively solve the problem of POI data duplication and make the application of POI data more perfect
