Evaluation in the Possibilistic Framework for Object Matching

In current research, a possibilistic, hierarchical approach for identification of co-referent objects (also called object matching) has been proposed as a generalisation of the record linkage problem. This approach offers a natural view to the matching of co-referent objects and uses logical possibilistic operators to calculate a final result. The development of evaluation operators, to deliver basic possibilistic statements is, up till now, still in it’s infancy. This paper introduces a formal basic definition of such operators and presents data type specific evaluation operators for sets.
