Schema mapping verification: the spicy way

... depends on the quality of the input correspondences. In this paper, we introduce the Spicy system, a novel approach to the problem ... of mappings. Spicy is based on a three-layer architecture, in which a schema matching module is used to provide input to a mapping ...

Evolution of the COMA match system

... ontology matching systems COMA and COMA++ are widely used in the community as a basis for comparison of new match approaches. We give an overview of the evolution of COMA during the last decade. In particular we discuss lessons learned on strong points and remaining ...
