Abstract

Mobile Web search will gain more importance. This paper proposes a novel method for query refinement based on real-world contexts of a mobile user, such as his/her current geographic location and the typical activities at the location which are extracted by Blog mining. Our method enhances location-awareness and even further context-awareness to the existing location-free keyword-based Web search engines.
