Wolfgang Nejdl – L3S Research Centre


WstNET Lab: L3S Research Center

Home Page: Wolfgang Nejdl

Prof. Dr. Wolfgang Nejdl (born 1960) has been full professor of computer science at the University of Hannover since 1995. He received his M.Sc. (1984) and Ph.D. degree (1988) at the Technical University of Vienna, was assistant professor in Vienna from 1988 to 1992, and associate professor at the RWTH Aachen from 1992 to 1995.
He worked as visiting researcher / professor at Xerox PARC, Stanford University, University of Illinois at Urbana-Champaign, EPFL Lausanne, and at PUC Rio.

Prof. Nejdl heads the L3S Research Center ( as well as the Distributed Systems Institute / Knowledge Based Systems (, and does research in the areas of search and information retrieval, information systems, semantic web technologies, peer-to-peer infrastructures, databases, technology-enhanced learning and digital libraries. Some recent projects in the L3S context include the digital library EU projects LiWA and ARCOMEM, investigating Web archive management and advanced search in such an archive, the FET IP project LivingKnowledge, developing algorithms and methods to handle and exploit diversity, bias and opinion on the Web, and the GLOCAL project, focusing on event-based indexing of multimedia data on the Web. A recently started project, CUBRIK, develops algorithms and systems for human-enhanced time-aware multimedia search.

Wolfgang Nejdl published about 320 scientific articles, as listed at DBLP, and has been program chair, program committee and editorial board member of numerous international conferences and journals, most recently including the role of PC chair for WSDM’11 in HongKong, and WebSci’12 in Evanston, US, as well as general chair for ICDE’11 in Hannover, see also

Peter Monge is Professor of Communication at the Annenberg School for Communication and Professor of Management and Organization at the Marshall School of Business. His most recent book (with Noshir Contractor), Theories of Communication Networks, was published by Oxford University Press in Spring 2003. He has also published Communicating and Organizing (with Vince Farace and Hamish Russell), Multivariate Techniques in Human Communication Research (with Joe Cappella), Policing Hawthorne (with Janet Fulk and Greg Patton) and Reasoning with Statistics (5th ed, with Fred Williams). His research on organizational communication networks, collaborative information systems, globalization and communication processes, coevolutionary theory, and research methods has been published in numerous leading communication and organizational journals, handbooks, and book chapters. He is a former editor of Communication Research (1986 to 1993) and a fellow and former president of the International Communication Association (1997-1998). In 2003 he received the Distinguished Scholar award from the Organizational Communication and Information Systems Division of the Academy of Management, and the Distinguished Research Award from the Organizational Communication Division of the National Communication Association.

Deborah L. McGuinness – Rensselaer Polytechnic Institute


WstNET Lab: Rensselaer Polytechnic Institute

Home Page: Deborah McGuinness

Dr. Deborah McGuinness is a leading expert in knowledge representation and reasoning languages and systems and has worked in ontology creation and evolution environments for over 20 years. Most recently, Deborah is best known for her leadership role in semantic web research, and for her work on explanation, trust, and applications of semantic web technology, particularly for scientific applications. Deborah is co-editor of the Ontology Web Language which has emerged from web ontology working group of the World Wide Web (W3C) semantic web activity and has now achieved W3C Recommendation status. She helped start the web ontology working group out of work as a co-author of the DARPA Agent Markup Language program’s DAML language. She helped form the Joint EU/US Agent Markup Language Committee which evolved the DAML language into the oil-reference DAML OIL description logic-based ontology language. She is a co-author of one of the more widely used long-lived description logic systems (CLASSIC) from Bell Laboratories. Her work on languages (including OWL, oil-reference.html DAML OIL, OIL, CLASSIC, etc.) is aimed at providing languages that enable the next generation of web applications moving from a web aimed at human consumption to the semantic web aimed at machine consumption in support of intelligent assistants and web agents. Deborah is a leader in ontology-based tools and applications. She is a co-author and technical leader of the Stanford KSL ontology evolution environment. She also consulted to help VerticalNet design and build its Ontobuilder/Ontoserver ontology evolution environment. She also provided technical leadership for the Stanford project to help Cisco systems form its ontology evolution plan for its meta data formation work.

Deborah’s main research thrusts are in languages, tools, and environments for the semantic web. Deborah leads the Stanford Inference Web (IW) effort. IW provides a framework for increasing trust in answers from heterogeneous systems by explaining how the answers were derived and what they depended on. Inference Web supports this goal by providing infrastructure and an implemented web-based environment for storing, exchanging, combining, annotating, comparing, search for, validating, and rendering proofs and proof fragments provided by reasoners and query answering systems. Inference web is being used as an infrastructure for explanations in a number of DARPA, DTO, and NSF projects and in a few demonstration systems including the Explainable Semantic Discovery Service and the KSL wine agent. Deborah led the wine agent project as an early semantic web services demonstration system that integrates explanation (via Inference web), semantic web languages (via DAML OIL and OWL), semantic web query languages (via OWL-QL), and web services (via OWL-S).
