Tutorial at SMBM-2006

Semantic Mining in Bio-Medicine, Jena, April 9-13, 2006


Steffen Staab (U Koblenz): "Ontologies and the Semantic Web" (Tutorial IV)

Knowledge rich domains benefit if knowledge structures are made explicit and formal in order that they may be used by people as well as by machines. In recent years there has been intensive research towards representing and using two kinds of knowledge structures in particular. First, ontologies have been investigated as a means to formalize a conceptualization of a domain of interest, i.e. an ontology captures the terminology of a domain as it remains constant over all the different situations one may encounter for a domain. Second, the semantic web has been conceived as an idea to provide a world wide standard to represent data as well as ontologies - and to link such data and ontologies. While the standardization allows for easy exchange and reuse of encoded knowledge structures, the linkage of data and ontologies allows for occurrence of even large network effects by the community that exploits them.

In the tutorial we will approach the foundations for both ontologies and the semantic web and we will see some way of exploiting them in knowledge rich domains.

The structure of the tutorial is as follows:
What is an ontology? (20 min)
What is the Semantic Web? (20 min)
Representation language for ontologies and the semantic web (50min)
Semantic Integration (30 min)
Ontology learning from text (30 min)
Some uses of ontologies in text representation tasks (30 min)
