Context acquisition in just-in-time mobile information retrieval

Mobile users have the capability of accessing information anywhere at anytime with the introduction of mobile web search. However, they still need to devote time and effort in order to retrieve relevant information in mobile devices. Conversely, context is proposed to reduce users time and effort. The recognition of context is supported by the availability of embedded sensors in mobile devices. In this study, the context acquisition and utilization for mobile information retrieval are proposed. The “just-in-time” approach is exploited in which the relevant information is retrieved without the user requesting it. This will reduce the mobile user´s effort, time and interaction and present the relevant information to the user in the right time and at the right place.
