Abstract. In this paper, we discuss our experience in testing the HMatch matchmaking system by means of the tracks proposed in the ontology alignment evaluation initiative of 2006 1. HMatch is a system conceived for the goal of ontology matching in open and distributed systems. It is based on linguistic and structural matching techniques for the evaluation of affinity considering concept names and concept contexts. The paper discusses the results that have been obtained and the possible improvements of the matching techniques in ongoing and future work. 1 Presentation of the system HMatch is a system for dynamically matching distributed ontologies. It takes two ontologies as input and returns mappings that identify corresponding concepts in the two ontologies, namely the concepts with the same or the closest intended meaning. Mappings are established after an analysis of the similarity of the concepts in the compared ontologies. The similarity analysis is performed through affinity metrics to determine a measure of concept semantic affinity in the range [0, 1]. A threshold-based mechanism is enforced to set the minimum level of semantic affinity required to consider two concepts as matching concepts. HMatch is part of the Helios framework [4], conceived for supporting knowledge sharing and ontology-addressable content retrieval in peer-based systems. A more detailed description of HMatch can be found in [3]. 1.1 State, purpose, general statement With respect to the different purposes of matching, the state of HMatch is the following: – Ontology matching is the original purpose of HMatch which has been designed with the goal of working with the different languages of OWL (i.e., OWL Lite,
