User Interests Extraction at Unusual Events Based on Location and Search Information

Abstract

Since it has become possible to collect location information using GPS-equipped mobile terminals, there has been a great deal of research into understanding user characteristics by utilizing that location information.In this study, we propose a method to extract information that users want to know by using web search behavior data and location information associated with users.We show that the proposed method can extract information that users want to know at the time of a disaster and analyze it more precisely than existing methods.
