In this paper, we present a brief overview of Falcon-AO (version 0.7): a practical ontology matching system with acceptable to very good performance, a flexible architecture, and a number of unique features. We also show some preliminary results of Falcon-AO for this year’s OAEI campaign: evaluation on seven different matching tasks. 1 Presentation of the system As an infrastructure for Semantic Web applications, Falcon is a vision of our research group. It desires for providing fantastic technologies for finding, aligning and learning ontologies, and ultimately for capturing knowledge by an ontology-driven approach. It is still under development in our group.
