User behavior analysis of location aware search engine

The rapid growth of Internet access from mobile users has emphasised the importance of location specific information on the Web. A unique Web service called Mobile Info Search (MIS) from NTT Laboratories gathers information and provides location aware search facilities. We performed association rule mining and sequence pattern mining against an access log which was accumulated at the MIS site in order to get insight into the behavior of mobile users regarding spatial information on the Web. Details of the Web log mining process and the rules we derived are reported in this paper.
