We present Optima, a state of the art general purpose tool for ontology alignment that automatically identifies and matches relevant concepts between ontologies. The tool is supported by an intuitive user interface that facilitates the visualization and analysis of ontologies in N3, RDF and OWL and the alignment results. We demonstrate the usefulness of(More)
The problem of ontology matching is crucial due to decentralized development and publication of ontological data. An approach proposed towards matching the ontologies is by inferring a match between two ontologies as a maximum likelihood problem, and solves it using the technique of expectation maximization (EM). The structural and lexical similarities(More)
We present a new method for mapping ontology schemas that address similar domains. The problem of ontology matching is crucial since we are witnessing a decentralized development and publication of ontological data. We formulate the problem of inferring a match between two ontologies as a maximum likelihood problem, and solve it using the technique of(More)
