   Abstract

Electronic markets have gained much attention as institutions to allocate goods and services efficiently between buyers and sellers. However, calculating suitable allocations between buyers and sellers in such markets can easily become very tricky, particularly if the services and goods involved are complex and described by multiple attributes.

This talk will present a semantic policy description framework that draws from utility theory to specify configurable products with multiple attributes. The framework thus allows the declarative description of seller pricing policies as well as buyer preferences over these configurations. As part of the framework, we present a machine-interpretable representation language for the policies and a method to evaluate different trading object configurations based on these policies. Buyers and sellers can then publish their policies, allowing an independent matchmaker to select the best service allocation based on the given buyer preferences and seller pricing policies.

The talk will also include a discussion of the various activities that are currently going at the University of Karlsruhe in the area of service sciences.

Institute AIFB, University of Karlsruhe, Germany & FZI Research Center for Information Technology, Karlsruhe & Ontoprise GmbH, Karlsruhe Rudi Studer is Full Professor in Applied Informatics at the University of Karlsruhe, Institute AIFB (www.aifb.uni-karlsruhe.de/WBS). His research interests include knowledge management, Semantic Web technologies and applications, ontology management, data and text mining, service-oriented architectures, peer-to-peer systems, and Semantic Grid.

He obtained a Diploma in Computer Science at the University of Stuttgart in 1975. In 1982 he was awarded a Doctor’s degree in Mathematics and Computer Science at the University of Stuttgart, and in 1985 he obtained his Habilitation in Computer Science at the University of Stuttgart.

From 1977 to 1985 he worked as a research scientist at the University of Stuttgart. From 1985 to 1989 he was project leader and manager at the Scientific Center of IBM Germany.

Rudi Studer is also director in the research department Information Process Engineering at the FZI Research Center for Information Technologies at the University of Karlsruhe (www.fzi.de/ipe) and one of the presidents of the FZI Research Center as well as co-founder of the spin-off company ontoprise GmbH (www.ontoprise.de) that develops semantic applications.

He is engaged in various national and international cooperation projects being funded by e.g. Deutsche Forschungsgemeinschaft (DFG), the European Commission, the German Ministry of Education and Research, and industry. He is president of the Semantic Web Science Association (www.iswsa.org) and Editor-in-chief of the journal Web Semantics: Science, Services, and Agents on the World Wide Web (www.websemanticsjournal.org).
