Matching User's Semantics with Data Semantics in Location-Based Services

Mobility is having a tremendous impact on the design and use of information technology. Information services, in particular, are heavily challenged by this new framework, which calls for innovative solutions. One of the major issues for flexible information services is how to be able to correctly understand what is being requested by users, and how to find information that is relevant to the request. This paper focuses on such semantic issues, aiming at outlining the general problem as well as the specificity attached to location-based services, one of the major trends in mobile information systems.
