Is a richer address data model relevant for LBS?

Abstract

Geocoded addresses usually code location by a single point that has no attached semantics other than representing the address. The lack of semantics limits the accuracy of any geometric analysis, for example in route planning where the geocode seldom represents exactly the user’s destination. The chapter suggests a semantically and spatially richer address data model, and studies whether this model will significantly improve the accuracy of the geometric analysis in typical location-based services’ tasks. We apply two experiments, one on time gain in navigation, and the other on ranking for k-nearest neighbor queries. Outcomes from both experiments support the argument that location-based se..
