Problems solved by technology

[0004] However, the validity and correctness of the fields checked by program coding can only be checked for the correctness of each field, and in the actual POI data, even the correct data fields may need to satisfy each other. Only a certain relationship can determine that the entire POI data is truly valid and correct, and the above method cannot be verified in this case

Embodiment 1

[0020] figure 1 The method flow chart of an embodiment of the method for verifying point-of-interest data provided by the present invention, the execution subject of the method may be a device or a service system platform integrated with data processing functions. Such as figure 1 As shown, the verification method of the point of interest data specifically includes:

[0021] S101, acquiring POI data of points of interest to be verified in different data source formats;

[0022] The POI data to be verified in this embodiment can be obtained from various existing websites and webpages, such as Ctrip, Baidu, Sina, and the like. Due to the different sources of the POI data to be verified, the existing POI data mainly includes three formats according to the format of the data source: text format (such as txt text document), JSON format and XML format. The data fields contained in the obtained POI data are also relatively rich in content. In addition to information such as common...

Embodiment 2

[0054] figure 2 A schematic structural diagram of an embodiment of a device for verifying point of interest data provided by the present invention, which can be executed as figure 1 The method steps shown. Such as figure 2 As shown, the verification device of the point of interest data specifically includes: an acquisition module 21, a verification module 22 and an output module 23; wherein:

[0055] Obtaining module 21, for obtaining the point of interest POI data to be verified in different data source formats;

[0056] Checking module 22, is used for extracting the different data field that has correlation in POI data, and carries out the correlation check of the correlation that it has;

[0057] The output module 23 is configured to output the verification result obtained through the verification of the association relationship.

[0058] Further, the above-mentioned different data fields having an association relationship include: an address field and a location fiel...

Abstract

An embodiment of the invention provides a method and a device for verifying data of points of interest. The method includes acquiring the to-be-verified data of the points of interest (POI); extracting different data fields with associations in the data of the POI and verifying the associations of the data fields; outputting verification results acquired after the associations are verified. The to-be-verified data of the points of interest (POI) are in different data source formats. According to the technical scheme, the method and the device have the advantages that the data of the POI can be verified by the aid of the method and the device, and the verification efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of electronic map technology, in particular to a method and device for verifying point of interest data. Background technique [0002] In electronic maps, there is a type of data called Point of Interest (POI) 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. [0003] The accuracy of POI data determines the overall quality of the electronic map. If wrong POI data is recorded on the electronic map, it may lead to poor user experience. Therefore, for POI data collected through various methods or channels, it is necessary to do further verifica...
