Matching object catalogues

A catalogue holds information about a set of objects, typically classified using terms taken from a given thesaurus, and described with the help of a set of attributes. Matching a pair of catalogues means to find a relationship between the terms of their thesauri and a relationship between their attributes. This paper first introduces a matching approach, based on the notion of similarity, that applies to both thesauri and attribute matching. It then describes matchings based on mutual information and introduces variations that explore certain heuristics. Finally, it discusses experimental results that evaluate the precision of the matchings and that measure the influence of the heuristics.
