Semantic information interoperability in open networked system

In open networked systems, each node shares part of its informational resources on the network and is responsible of providing an ontological description for them. To enable semantic information interoperability in networked contexts with a multitude of autonomous ontologies, appropriate matching techniques are required to determine semantic mappings between concepts of different ontologies. In this paper, we describe H-Match, an algorithm for dynamically performing ontology matching in open networked contexts. H-Match provides several matching models and metrics to work at different levels of depth, with different degrees of flexibility and accuracy, thus supporting semantic interoperability in a flexible way.
