In an open context such as the Semantic Web, information providers usually rely on different ontologies to semantically characterize contents. In order to enable interoperability at a semantic level, ontologies underlying information sources must be linked by discovering alignments, that is, set of correspondences or mappings. The aim of this paper is to provide a formal model (i.e.,
Semantic Flow Networks
) to represent networks of ontologies and alignments with the aim to investigate the problem of composite mapping discovery.
Semantic Flow Networks
(
SFN
) differ from other models of networks of ontologies for two main aspects.
SFN
consider constraints over mappings that are necessary to take into account their dependencies. Moreover, a different notion of mapping, that is, compound mapping is considered. Complexity results and a CSP formulation for composite mapping discovery are provided.
