Problems solved by technology

[0003] However, trajectory data has disadvantages such as unstructured, huge data volume, and unclear semantics.
For example, for a user, the user's trajectory data is only a series of coordinate points on a two-dimensional plane, it is difficult to directly extract the user information expressed by the trajectory data

Abstract

The present application discloses methods and apparatus for generating information. A specific embodiment of the method includes: obtaining a geographic information point sequence set and an identification set composed of the identifiers of each geographic information point sequence in the geographic information point sequence set; for each geographic information point sequence set in the geographic information point sequence set Information point sequence, clustering the geographic information points in the geographic information point sequence to generate an element sequence corresponding to the geographic information point sequence; using machine learning methods, based on the identification set and the generated element sequences, learn to obtain A matrix for each identifier in the identifier set; for each identifier in the identifier set, based on the identifier and the matrix, generate information about the user to which the geographic information point sequence indicated by the identifier belongs. This embodiment enables targeted information generation.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method and device for generating information. Background technique [0002] With the emergence of mobile positioning devices, more and more trajectory data of users can be collected. Trajectory data is widely believed to be able to characterize user behavior from multiple angles, and plays an important role in understanding user characteristics and tendencies. And the information extracted from the trajectory data to characterize the user's characteristics and tendencies can be applied to credit modeling, information push, etc. [0003] However, trajectory data has disadvantages such as unstructured, huge data volume, and unclear semantics. For example, for a user, the user's trajectory data is only a series of coordinate points on a two-dimensional plane, and it is difficult to directly extract the user inform...
