However, the current mobile browsers are implemented without considering the characteristics of mobile searches. As a result, mobile users need to devote time and effort in order to retrieve relevant information from the web in mobile devices. On the other hand, mobile users often request information related to their surroundings, which is also known as context. This recognizes the importance of including context in information retrieval. Besides, the availability of the embedded sensors in mobile devices has supported the recognition of context. In this study, the context acquisition and utilization for mobile information retrieval are proposed. The “just-in-time” approach is exploited in which the information that is relevant to a user is retrieved without the user requesting it. This will reduce the mobile user’s effort, time and interaction when retrieving information in mobile devices. In this paper, the context dimensions and context model are presented. Simple experiments are shown where user context is predicted using the context model. Keywords: Context recognition, mobile information retrieval, just-in-time information access INTRODUCTION It is common now for people to address their information needs by using the web search in mobile devices. Since mobile users are connected to the Internet almost every minute, accessing Article history: Received: 31 March 2012 Accepted: 31 August 2012 E-mail addresses: azri@fsktm.upm.edu.my (Az Azrinudin Alidin), fabio.crestani@usi.ch (Fabio Crestani) *Corresponding Author information has become much faster than years before mobile Internet was introduced. However, performing information retrieval (IR) on mobile devices is rather complex because mobile browsers are implemented without considering the characteristics of
