owards Better Semantics in the Multifeature Querying.
Peter Gurský · DATESO · 2006
Nowadays the natural requirement of users is to retrieve the best answers for the criteria they have. To explain, what kind of objects user prefers, we need to know, which values of properties are suitable for the user. We assume that each property is possibly provided by an external source. Current algorithms can effectively solve this requirement, when the sources have the same ordering as the user preferences. Commonly, two users prefer different values of a given property. In this paper we describe how we can consider this feature.
