ESWC Summer School 2011 is glad to announce the following Keynote Speakers:

Christian Bizer

Chris Bizer

Professor Christian Bizer is the head of the Web-based Systems Group at Freie Universität Berlin. The group explores technical and economic questions concerning the development of global, decentralized information environments.
Christian Bizer initialized the W3C Linking Open Data community project and the DBpedia project, an effort to extract structured data from Wikipedia and to publish the extracted data as Linked Data on the Web. Other results of his work include the Named Graphs data model which was adopted into the W3C SPARQL standard, the D2RQ mapping language which is widely used for publishing relational databases to the Web of Linked Data, and the Berlin SPARQL Benchmark for measuring the performance of RDF stores.

Fausto Giunchiglia

I have done research in many different (but very related!) areas. Some keywords which could be used to describe my work are (in decreasing order of generality): Artificial Intelligence, Formal Methods, Software Engineering (to some extent), automated reasoning, theorem proving, model checking, planning, contexts and contextual reasoning (and logics for modeling it), abstract reasoning, meta-theoretic reasoning, reasoning about propositional attitudes (belief mainly), integration of reasoning systems, agents and agent oriented software engineering, Peer-to- Peer data bases, knowledge management, contextual ontologies, "diversity in knowledge management", ... My current interests go in two directions:


From a scientific point of view, I am still very much interested in the notion of context. My recent focus is the study of how its can be used to manage data, content and knowledge in the large in real world applications. My reference application domain is a peer-to-peer enabled (Semantic) Web, while I guess a good title for my current research is Managing diversity in knowledge.

In the last few years, I have become very interested in the issue of the impact of Technology, and Computer Science in particular, on organizations, people and society. I got involved in this not so much as a research exercise but as a consequence of some managerial positions I have taken, mainly related to my Academic role at the University of Trento. Although I have never published any scientific paper on these issues, I have written various documents (mostly in Italian) which I believe are of some interest.

Mark Greaves

Mark Greaves

Dr. Mark Greaves is currently Director, Knowledge Systems at Vulcan, Inc. Vulcan is the private investment vehicle for Paul Allen (co-founder of Microsoft, At Vulcan, he is sponsoring advanced research in large knowledge bases and advanced web technologies, including Project Halo (

Formerly, Mark was Program Manager in DARPA's Information Exploitation Office (IXO) for the DAML, UltraLog, and Advanced Logistics Projects. At DARPA, he has sponsored research on logistics and supply chain control technologies, formal ontology specification, semantic web technology, and the application of software agent technology to problems of distributed control of complex systems-of-systems. Prior to coming to DARPA, he led advanced programs in software agent technology at the Mathematics and Computing Technology group of Boeing's Phantom Works division. His main research interests are in mathematical logic, semantic web, and software agent technology, about which he has published two books and several papers.

Ian Horrocks

Ian Horrocks is a Professor in the Oxford University Computing Laboratory where he (jointly) leads the Information Systems Group. His research interests include knowledge representation, ontologies and ontology languages, modal and description logics, automated reasoning, implementation and optimisation of reasoning systems, and applications in areas such as e-Science and the Semantic Web. He was centrally involved in the development of the OIL, DAML+OIL and OWL ontology languages, and was co-chair of the W3C Working Group that recently developed OWL 2. He also developed algorithms and implementation techniques that are employed in many reasoning systems, and implemented the well known FaCT system in which many of these algorithms and implementations techniques were first deployed. He has published more than 150 articles in conferences, journals and books. He is a BCS Fellow, an ECCAI Fellow, an EPSRC Senior Research Fellow and a past winner of the BCS Roger Needham award.

Chris Welty

Chris Welty

Chris Welty is a Research Scientist at the IBM T.J. Watson Research Center in New York. Previously, he taught Computer Science at Vassar College, taught at and received his Ph.D. from Rensselaer Polytechnice Institute, and accumulated over 14 years of teaching experience before moving to industrial research. Chris' principal area of research is Knowledge Representation, specifically ontologies and the semantic web, and he spends most of his time applying this technology to Natural Language Question Answering as a member of the DeepQA/Watson team and, in the past, Software Engineering. Dr. Welty is a co-chair of the W3C Rules Interchange Format Working Group (RIF), serves on the steering committee of the Formal Ontology in Information Systems Conferences, is president of KR.ORG, on the editorial boards of AI Magazine, The Journal of Applied Ontology, and The Journal of Web Semantics, and was an editor in the W3C Web Ontology Working Group. While on sabbatical in 2000, he co-developed the OntoClean methodology with Nicola Guarino. Chris Welty's work on ontologies and ontology methodology has appeared in CACM, and numerous other publications.
