Method for rearranging information of points of interest

Abstract

The invention relates to an information rearrangement technology. A method for rearranging information of points of interest comprises the following steps of: 1, receiving information of a point of interest A by a system; 2, inquiring names of all points of interest in a first region by taking the longitude and latitude of the point of interest A as a reference point; 3, matching and rearranging the point of interest A and other searched points of interest according to a position excursion matching method, and thus obtaining a rearrangement result and matching precision; 4, if the matching precision P1 obtained in the step 3 is greater than or equal to preset precision P', turning to the step 9, otherwise, turning to the step 5; 5, inquiring names of all points of interest in a second region range, and repeating the step 3; 6, if the matching precision P2 obtained in the step 5 is greater than or equal to the preset precision P', turning to the step 9, otherwise, turning to the step 7; 7, inquiring names of all points of interest in a third region range, and repeating the step 3; 8, if the matching precision P3 obtained in the step 3 is greater than or equal to preset precision P', turning to the step 9; and 9, outputting the rearrangement result.

Description

technical field [0001] The invention relates to information deduplication technology, in particular to a deduplication method for interest point information. Background technique [0002] With the popularization of electronic map navigation (GIS) technology, electronic maps have introduced data such as names and brief introductions of places of interest to people, such as government agencies, tourist attractions, hotels, restaurants, shopping malls, and hospitals. Points of Interest (POI), and data information such as names and brief introductions of these places are collectively referred to as POI information. [0003] When people use the electronic map, they can obtain the corresponding POI information incidentally. The POI information generally includes the name, type, latitude and longitude, detailed address, contact number, etc. of the POI. In the process of collecting and saving points of interest, in order to ensure the legality, reliability, validity and uniqueness ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to propose a method for deduplication of interest point information, based on the location, combined with a method of position offset matching based on the collected interest point information, to achieve high Matching deduplication method, so as to solve the problem of eliminating data redundancy with high precision that cannot be achieved by existing deduplication technology
