Spatio-Temporal Proximity as a Basis for Collaborative Filtering in Mobile Environments
We propose a new approach to collaborative filtering in mobile tourist information systems based on spatio-temporal proximity in social contexts. Users store ratings and reviews of locations and events locally within their personal information system and then exchange these with other users present in the same social contexts using ad-hoc networking and opportunistic information sharing. We describe some preliminary investigations on the use of these methods in a mobile information system for visitors to a festival.
