Abstract

The embodiment of the invention provides a geographic position-based interest point indexing method and device, a medium and an electronic device. The geographic position-based interest point indexingmethod comprises the steps of obtaining the latitude and longitude information carried in a user request, and encoding the latitude and longitude information to obtain a corresponding target geographic block code; mapping the target geographic block code into a code of a target group containing the target geographic block; expanding the target group according to the score of the target group anda request condition carried in a user request to obtain an expansion group; and obtaining the interest points corresponding to the target group and the expansion group according to the code of the target group and the code of the expansion group. According to the technical scheme, the target group is expanded according to the interest point score, and the purpose of controlling the number and quality of the indexed interest points is achieved. Meanwhile, when the user is located at the edge of the geographic block, the problem that the interest point is not matched with the user or retrieval is incomplete can be solved through index extension.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a method, device, medium and electronic device for indexing POIs based on geographic location. Background technique [0002] As users have higher and higher requirements for personalized services, general search engines have gradually derived a search mode of point-of-interest index. The POI index refers to a search mode for selecting a corresponding category according to a user's interests and querying relevant POI information. For example, finding high-quality and suitable group-buying information near the user's location on a group-buying website is a point-of-interest index. At present, the common way of indexing POIs is based on geographic location. It divides the longitude and latitude into blocks according to certain rules, and retrieves the corresponding POIs in the geographic block where the user is located, so as to achieve the purpose of matching POIs with...
