AIC Seminar Series

Formal Semantics and Ontologies

Frank LoebeUniversity of Leipzig[Home Page]

Notice:  Hosted by Vinay Chaudhri.

Location:  EJ228 (SRI E building)  (Directions)


In this talk, I present an inquiry on the mutual interplay between formal language semantics and ontologies represented in such languages. The discussion applies in general, yet mainly first order logic is referred to as a prototypical case. The considerations involve a thesis that suggests a clear distinction between the intended, conceptual semantics of formal ontology representations and their formal semantics. This leads to difficulties in ontology translations between formal languages. Moreover, the distinction entails the problems of (1) how to capture that first kind of semantics and (2) finding a revised version of language translations that preserve conceptual meaning. I sketch a corresponding working proposal (mainly for the first task) and address ways to accommodate that with existing formalisms and tools.

   Bio for Frank Loebe

Frank Loebe received an MSc degree in computer science (in German "Diplom Informatik") from the University of Leipzig, Germany, in 2003. Since then he is a PhD student working in Applied Ontology at both, the Institute of Medical Informatics, Statistics and Epidemiology (IMISE) and the Department of Computer Science at the University of Leipzig.

His work is closely related to a long-term effort pursued by the research group Ontologies in Medicince (Onto-Med) at IMISE, which is the development of the top-level ontology General Formal Ontology (GFO). In this context, Frank has been involved in ontological analyses of several top-level categories, including role, relation, function, property, time, and process, in combination with applications in the life sciences in most cases. Moreover, he is working on the intersection of language semantics and ontologies, mainly focusing on logical languages.
