BEHAVIORAL ATTRIBUTE ANALYSIS METHOD AND DEVICE

摘要

Provided is a technology for extracting a user behavior pattern from history data accumulating personal behaviors, and enabling exhaustive and efficient analysis of a user behavior tendency or features from various aspects, such as location and time, using the pattern. A behavioral characteristics analysis device according to the present invention expresses a behavior pattern by scene vectors describing behaviors of a set of persons as scene values in each time band, extracts a life pattern included in all of the set of persons by clustering the scene vectors, and performs classification based on to which life pattern each person belongs (see FIG. 1).

主权项

1. A behavioral characteristics analysis device comprising:
a scene extraction unit that extracts, from history data recording a behavior history of a group of persons, a scene in which a person belonging to the group of persons behaved; a scene vector generation unit that expresses a transition of the scenes extracted by the scene extraction unit for each person as scene vectors having a time band of a day as an element number and a value representing the scene corresponding to the element number as an element value, and that stores scene vector data describing the scene vectors in a storage device; a life pattern extraction unit that extracts a transition pattern of the scenes by clustering the scene vectors, thus extracting the transition pattern as a life pattern included in the group of persons; and a life pattern analysis unit that clusters analysis objects by characterizing the analysis objects by the frequency of appearance of the life pattern in the history data in association with the analysis objects.
