Title
Functional Dependencies Over Possibilistic Databases: An Interpretation Based on the Possible Worlds Semantics
Abstract
In this paper, we introduce a definition of the concept of a functional dependency (FD) in the context of databases containing ill-known attributes values represented by possibility distributions. Contrary to previous proposals, this definition is based on the possible worlds model and consists in viewing the satisfaction of an FD by a relation as an uncertain event whose possibility and necessity can be quantified. We give the principle of a method for incrementally computing the related possibility and necessity degrees and tackle the issue of tuple refinement in the presence of an FD.
