Title:
STAY POI ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/047949
Kind Code:
A1
Abstract:
The present invention addresses the problem of estimating a point of interest (POI) where a user has stayed. A stay POI estimation device 1 comprises an estimation unit 12 that estimates a stay POI on the basis of user information, which is a time-series history of each user's stays during move, some of which are stays associated with a POI where the user has stayed, and proximity to other users, the stay POI being a POI where the user has stayed in an unassociated stay, which is a stay not associated with a POI among the stays included in the user information. The estimation unit 12 performs a simulation for each user assuming that the user has moved via POI candidates, which are candidates for the stay POI, and estimates the stay POI out of the POI candidates on the basis of matching on the time series between proximity between users extracted in the simulation and proximity included in the user information.
