Abstract

The invention discloses a positioning method and a device. The method according to one embodiment comprises the following steps: acquiring positioning information of a user and a geographic information point category sequence historically visited by the user before the positioning time, wherein the positioning information comprises the positioning time and a positioning coordinate; acquiring at least one geographic information point of which the geographic information point coordinate has a distance, less than a preset distance threshold, from the positioning coordinate, wherein the geographic information point comprises the geographic information point coordinate and the geographic information point category; on the basis of the positioning information and the geographic information point category sequence historically visited by the user before the positioning time, confirming a visiting probability value of a geographic entity indicated by the geographic information point visited by the user at the positioning time, for each geographic information point in at least one geographic information point; confirming the geographic information point corresponding to the geographic entity indicated by the user at the positioning time according to each confirmed visiting probability value. According to the embodiment, the accuracy of the user positioning is increased.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, especially to a positioning method and device. Background technique [0002] With the continuous development of mobile Internet, mobile smart devices and terminals, terminal users generate a large amount of offline data such as positioning and trajectory. Offline data truly reflects the behavioral characteristics of users in physical time and space, and forms a good supplement to online data. The combination of offline data and online data can achieve more accurate user portraits. User portraits can be widely used in many specific applications such as online information push and precision marketing. In particular, if it can be determined or predicted that the user has visited a geographic information point (POI, Point Of Interest), also known as "information point" or "point of interest", such as hotels, schools, shopping malls, offi...
