HPI-Kolloquium: "Web Science, Web Analytics and Web Archives – Humans in the Loop"

Prof. Dr. Wolfgang Nejdl
(Institut für Verteilte Systeme, Forschungszentrum L3S)

9. Januar 2014


The Web stands for a huge and diverse infrastructure with an incredible amount of data. But what sets it apart from other infrastructures are its users: billions of users with very diverse backgrounds and goals who are shaping the Web. Humans introduce diversity into the Web, and work together creating amazing amounts of information, annotations and data sets. These different aspects of diversity create problems for our algorithms but also opportunities for coping with them, and I will illustrate this using some examples.

I will further discuss current and future work at L3S related to Web Archives, building on projects currently running at L3S, including a new ERC Advanced Grant, ALEXANDRIA. Search and analysis in Web Archives are different from their counterparts on the Web and again involving humans is a crucial ingredient in coming up with good solutions.


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 re-searcher / 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 digi-tal libraries. Wolfgang Nejdl published more than 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, WebSci'12 in Evanston, US, CIKM'13 in San Francisco, and for the WWW'13 Social networks and Graph Analysis Track in Rio De Janeiro.
