Problems solved by technology
[0005] The inventors of the present application have found that there are at least the following problems in the prior art: the existing method for establishing a point of interest establishes a correspondence between a position point information and attribute information such as an entity name, when the position occupied by the entity is not a point , for example, when it is a community or a road, the existing method of creating a point of interest cannot show an area or a road that is consistent with the entity
Therefore, the existing methods for establishing POIs create inaccurate POI information

A method and device for establishing points of interest are disclosed in embodiments. The method includes dividing a detected zone according to a preset edge length to obtain unit grids having the preset edge length; coding the unit grids according to a first preset rule; acquiring log data corresponding to the unit grids, with the log data including mobile log data and / or static log data; determining a first type point of interest in the detected zone according to the mobile log data; and determining a second type point of interest in the detected zone according to the static log data. The device and the method which are provided can improve accuracy of information of established points of interest.
Description
technical field [0001] The present application relates to the technical field of information processing, and in particular to a method and device for establishing points of interest. Background technique [0002] With the vigorous development of the mobile Internet, location-based services (Location-based service, LBS) are accepted by more users, for example, by searching for a place name, the geographical location corresponding to the place name can be found on a map. [0003] Point of interest (POI) is an important concept in location-based services. A point of interest can represent a location entity in an electronic map. These location entities can be factories, schools, shops, park points. [0004] Existing methods for establishing points of interest generally include: establishing a correspondence between geographic location information and a location entity corresponding to the location information, for example, the latitude and longitude information of a location e...
