PILGRIM: A Location Broker and Mobility-Aware Recommendation System

Mobile computing adds a new, mostly unexplored dimension to data mining: the user's position is now a relevant information, and recommendation systems, i.e. services that select and rank a small number of links that are probably of interest to the user, have the opportunity to take location into account. The use of location discovery systems, that automatically detect the device location, relieve the user from the burden of explicitly inserting that information when formulating a query. In this paper, a mobility-aware recommendation system that uses the location of the user to filter recommended links is proposed. To avoid the potential problems and costs caused by systems where the bindings between locations and resources are inserted by hand, a new middleware layer, the location broker"
