Embodiment 1

[0052] Aiming at the traditional POI manual sorting method, the embodiment of the present invention provides a sorting method using Internet technology. refer to figure 1 , is a flowchart of a method for sorting electronic map data according to Embodiment 1 of the present invention. In this embodiment, the electronic map data is described by taking POI data as an example, but the electronic map data includes but not limited to POI data.

[0053] S101, extracting keywords of each POI data;

[0054] In this embodiment, a keyword needs to be extracted from each POI data to be used for querying in an Internet search engine. Since each POI data has some attributes, including name, category, coordinates or other attribute information, the words that best represent the POI data can be extracted from these attribute information as keywords during extraction. In this embodiment, the basic part of the keyword is the name of the POI, because the name is the most important part of the ...

Embodiment 2

[0069] Embodiment 2 of the present invention provides a specific application example.

[0070] refer to figure 2 , is a schematic flowchart of a POI data sorting method described in Embodiment 2 of the present invention.

[0071] S201, preprocessing the original POI data;

[0072] The main function of cleaning and filtering the original POI data is to make the data meet certain input standards. The preprocessing mainly includes three parts: removal of irrelevant symbols, conversion of character codes, and adjustment of unified format. in,

[0073] 1) Remove irrelevant symbols: Due to the source of the data or other problems, there may be some irrelevant symbols in the data, these symbols have no practical meaning, such as! , # and other symbols, as well as garbled characters, etc., these irrelevant symbols need to be removed to play a cleaning and filtering role;

[0074] 2) Character encoding conversion: Make the encoding of characters consistent, which can be beneficia...

Abstract

The invention discloses a priority method of electronic map data and a device, which solves the problem that a traditional artificial priority method causes a poor priority effect, wastes manpower and has high cost. The method comprises that a key word of each electronic map data is extracted, web sets of search results, which correspond to each electronic map data are obtained through that the key word is used to search. According the corresponding wet sets of search results of each electronic map data, the importance of the electronic map data is calculated, and the electronic map data is sorted according to the importance. The invention uses the internet popularity of internet to depict the importance degree of POI data, because the depiction represents the recognition of vast netizen even broad masses, the priority effect is better and has excellent mass basis and rationality. Further, a machine is used to automatically score and sort, thereby the man labor is effectively saved, the efficiency is higher, and the cost is very low.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a sorting method and device for electronic map data. Background technique [0002] With the development and improvement of geographic information system, the design and development technology of electronic map is becoming more and more mature. In electronic maps, there is a type of data called point of interest data (Point of Interest, POI data), which refers to data that people are interested in, such as geographic information of restaurants, parks, shopping malls and other buildings, or information about some streets, etc. Wait. Usually, POI data includes information on four aspects: name, category, longitude, and latitude, and sometimes other information, such as address, phone number, zip code, and so on. POI data is one of the most important elements of electronic maps, and it is also the information that people pay most attention to when using electronic maps. [0003] ...
