OPTIMA: Tool for Ontology Alignment with Application to Semantic Reconciliation of Sensor Metadata for Publication in SensorMap

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 Optima toward the automatic publication of sensor net data feeds in public portals such as Microsoft SensorMap.
