A method and device for verifying point of interest data

Abstract

The invention discloses a point of interest data verification method and a point of interest data verification device. The point of interest data verification method comprises the following steps of: extracting road name information from the address information of the to-be-verified POI (Point of Interest); determining corresponding road 1 on a map according to the road name information; and judging whether other roads exist between the POI and the road 1 or not, if so, marking the POI data as error data. In the above scheme, the data, which possibly has errors, can be automatically found out from a large number of POI data, so that the manual verification cost is lowered. Compared with the prior art, the method and the device provided by the invention carry out verification by using the information of the POI more, thus the method and the device are less limited by the data sparseness, and have better applicability. Moreover, according to the scheme of the embodiment provided by the invention, verification is carried out according to the relative positions of the POI and the road, so that the setting of a decision threshold is negligible, and the method and the device can be implemented simply.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a method and device for verifying point of interest data. Background technique [0002] Electronic map, also known as digital map, is a map stored and queried digitally using computer technology. In electronic maps, there is a type of data called POI (Point of Instterest, point of interest) data, which refers to the location data that people are interested in on the map, such as geographic information of restaurants, parks, shopping malls and other buildings, or some streets information and so on. Usually, POI data includes several aspects of information such as name, address, location, category, etc., and sometimes further includes other auxiliary information, such as phone number, zip code, and so on. POI is one of the important elements in the electronic map, and it is also the information that most users pay attention to when using the electronic map. [0003] The ...

AI Technical Summary

Problems solved by technology

This method can achieve automatic verification of POI data to a certain extent, but it is also limited by data sparseness: if there are no points with the same or similar addresses, verification cannot be achieved

In addition, in the actual calibration process, the distance threshold is not easy to control, too large or too small may have a negative impact on the calibration results
