Sean Bechofer   Sean Bechhofer is a Lecturer in the Information Management Group of the University of Manchester, having spent the period from 1993 to 2004 as a Research Fellow. His research interests are centered around the technologies required to implement and deliver the Semantic Web and over the last ten years, he has helped produce a number of tools and infrastructure to support the use of Semantic Web technology. Through the COHSE project, Sean was involved in marrying together hypermedia and semantics, producing an early example of a Semantic Web system. He was primarily responsible for the development of OilEd, one of the first ontology development tools to utilise DL style reasoning. He was a participant in the W3C WebOnt Ontology Language Working Group, providing an implementation of a validating parser for OWL along with supporting infrastructure for the use of OWL in applications. Sean is also currently Research Area Manager for the EU Network of Excellence KnowledgeWeb, an EU thematic network that co-ordinates leading research groups in the Semantic Web area. He has given a number of invited talks and tutorials and has published over fifty articles in journals, conferences and workshops.

Jerome Euzenat   Jérôme Euzenat is senior research scientist at INRIA (Montbonnot, France). He has set up and leads the INRIA Exmo team dedicated to “Computer-mediated communication of structured knowledge” which is also part of the Laboratoire d'Informatique de Grenoble (Grenoble computer science lab). Dr Euzenat has contributed to reasoning maintenance systems, object-based knowledge representation, symbolic temporal granularity, collaborative knowledge base construction, multimedia document adaptation and semantic web technologies. His all time interests are tied to the relationships holding between various representations of the same situation. Hence, his interest in connecting heterogeneous ontologies. His work on heterogeneity, partially carried out in Knowledge web, has been recently published as a book, Ontology matching, written in collaboration with Pavel Shvaiko.
