Abstract
This paper deals with the issue of data fusion, which arises once reconciliations between references have been determined. The objective of this task is to fusion the descriptions of references that refer to the same real world entity so as to obtain a unique representation. In order to deal with the problem of uncertainty in the values associated with the attributes, we have chosen to represent the results of the fusion of references in a formalism based on fuzzy sets. We indicate how the confidence degrees are computed. Finally we propose a representation in Fuzzy RDF, as well as its flexible querying by queries expressing users’ preferences.
