Embodiment Construction

[0061] By providing a method and device for constructing a semantic location history, the embodiment of the present invention solves the technical problem of manual operation and consumes a lot of manpower and material resources in the prior art, and realizes the technical effect of automatically constructing a semantic location history at low cost.

[0062] The technical solution in the embodiment of the present invention is to solve the above technical problem, and the general idea is as follows:

[0063] Firstly, expand a certain area based on the coordinates of the points of interest to form the original interaction area; and obtain the user's movement track; then filter out the stay points in the original interaction area from the movement track according to the construction conditions; finally, it will correspond to the stay point The semantic information of the points of interest is assigned to the stay points on the moving track, so as to obtain the semantic location history...

Abstract

The invention discloses a method and a device for constructing a semantic position history. The method at least comprises the following steps: expanding a certain region outwards based on coordinates of interest points, so as to form an original interaction region; acquiring a moving track of a user; screening staying points in the original interaction region from the moving track according to a construction condition; and assigning semantic information of the interest points corresponding to the staying points to the staying points on the moving track, so as to obtain the semantic position history. Compared with the prior art, the method has the advantages that the manual operation is omitted, or additional equipment does not need to be mounted, so that the technical problems the manual operation is required, and a large number of manpower and material resources are consumed in the prior art are solved, the time and the labor are saved, and the construction precision is further improved.

Description

Technical field [0001] The present invention relates to the technical field of positioning, in particular to a method and device for constructing a semantic location history. Background technique [0002] As the indoor space for people’s activities becomes larger and more complex, points of interest (POI) become more and more abundant, and related services (such as positioning, navigation, recommendation, etc.) in parking lots, shopping malls, airports, etc. The demand is increasing. With the development of mobile Internet and location-aware technology, location-based services (LBS) are well known and widely used. With the vigorous development of smart sensor devices, people have higher and higher demands for real-time, smart, and precise LBS. [0003] Location-based services are mainly based on the user's location, make reasonable inferences about the user's interests and behavior, and then provide users with related services. However, the existing location information represen...
