Location-based indexing for mobile context-aware access to a digital library
نویسندگان
چکیده
Mobile information systems need to collaborate with each other to provide seamless information access to the user. Information about the user and their context provides the points of contact between the systems. Location is the most basic user context. TIP is a mobile tourist information system that provides locationbased access to documents in the digital library Greenstone. This paper identifies the challenges for providing efficient access to location-based information using the various access modes a tourist requires on their travels. We discuss our extended 2DR-tree approach to meet these challenges.
