Ontology Matching


Falcon is an infrastructure for Semantic Web applications, which aims at providing fundamental technology for finding, aligning and learning ontologies, and ultimately for capturing knowledge from the Web via an ontology-driven approaches.

Falcon-AO, a prominent component of Falcon, is an automatic ontology matching tool that helps actualize interoperability between (Semantic) Web applications that use different but related ontologies. Recently, it has become a very practical and popular choice for matching Web ontologies expressed by RDF(S) and OWL. Falcon-AO is implemented in Java, and presently, it is an open source project under the Apache 2.0 license.

To date, we have proposed a number of novel approaches for Falcon-AO, including V-Doc (a linguistic matcher), GMO (an iterative structural matcher) and PBM (a partition-based matcher for large ontologies). Further, we also address related research topics such as block (many-to-many) matching (BMO), matching between relational database schemas and ontologies (Marson).
