The invited speaker of the day was Richard Benjamins (iSOCO, Telephonica), about “Semantic Solutions for the Enterprise,” he talked about the market, Gartner Hype Cycle 2006 predictions, public and corporate semantic applications and cost factors for constructing ontologies.
Next, Jérôme Euzenat presented at a very fast pace, the role, state of the art and future in ontology matching and alignment; and we got a taste of various matching algorithms in the afternoon practical session.
Asunción Gómez Pérez, gave a presentation on ontological engineering — development process, ontology lifecycle, methods and methodologies for building ontologies, and the tool suites and languages that support them. Most of the things were part of NeOn Project, the NeOn glossary of activities is a nice overview of what ontological engineering deals with.
In the afternoon, another practical session was lead by Aldo Gangemi, where we had to build an simple (and funny) ontology using another set ontology patterns than the ones discussed in the previous day. If in the previous day we played with Protégé 4, now we designed the ontology with TopBraid Composer. (I wonder what is the acceptance within this community of Altova’s SemanticWorks).
Later we had a extreme short walk in mountains, where we followed briefly one of the footpaths of the Fuenfría Valley.
