The application that the user's contexts are continuously changed over time requires an efficient information retrieval. This paper proposes a new context-differentiated information retrieval method for an efficient ubiquitous service. This enables the rapid retrieval, because of no access to the most detail information at a time. This paper describes the retrieval method, the algorithms and the experimental results.
