Neon: Lifecycle Support for Networked Ontologies Priority: Ist-2004-2.4.7 — " Semantic-based Knowledge and Content Systems " D3.3.3: Integration of Ontolight with the Alignment Server Neon Consortium Work Package Participants Change Log

This deliverable describes the integration of the OntoLight matcher within the Alignment server and the NeOn toolkit. This integration uses a web service connection from the Alignment server to an OntoLight web service interface. The following partners have taken an active part in the work leading to the elaboration of this document, even if they might not have directly contributed to the writing of this document or its parts: Executive Summary In the NeOn project, context can be expressed within a network of ontologies through relationships between ontologies. Such relationships would provide the missing axioms that specify the meaning of knowledge further and help considering them in their context. These relations must be established from the initial resources which will be linked to contextual resources. This can be achieved through the use of ontology matching techniques. In order to help networked ontology designers to contextualise ontologies, we have already integrated within the NeOn toolkit a plug-in for finding alignments between ontologies and importing them within the network of ontologies. There are systems which cannot be integrated within the NeOn toolkit or even within an Alignment server either because they depend on local resources, e.g., databases, they consume large amount of resources or they cannot be easily ported. For these systems to be adequately exploited by the Alignment server and the NeOn Alignment plug-in, it is necessary to establish connection. This deliverable presents the work done for the introduction of the OntoLight matcher within the Alignment server which can compute and provide alignments for the NeOn toolkit Alignment plug-in. More generally, it provides a web service interface specification which enables any matcher to be interfaced with the Alignment server. For that purpose, we have defined a new kind of alignment method which connects to a web service for performing the match. The web service interface is specified in WSDL and is used for connecting the Alignment server to OntoLight.
