摘要:

In the past 17 years, the Web has developed into a worldwide information

and communication infrastructure with a considerable influence on

business, science, and society. Despite its unprecedented growth, or

perhaps because of it, and because of the wealth of applications that

build on this infrastructure, the challenges faced by the Web as a whole

are also greater than they were 17 years ago. Many of the necessary

solutions can only be developed with a combination of methods and

technologies taken from various areas of information technology and

computer science - supported by contributions from social sciences,

business, and law.

In this talk I will give an overview over the current L3S core research

areas and some of our results, focusing on diversity of information,

events as organizing concepts, and analysis of web user behavior. Last,

I will discuss our planned extension beyond computer science topics with

colleagues from sociology, psychology, linguistics and other

disciplines.

演讲人简介:

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 (http://www.L3S.de/) as well

as the Distributed Systems Institute / Knowledge Based Systems

(http://www.kbs.uni-hannover.de/), 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 artificial intelligence. Some recent

projects in the L3S context include the PHAROS Integrated Project on

audio-visual search, the OKKAM IP focusing on entities on the Web, the

Digital Library EU project LiWA, coordinated by L3S, which

investigates Web archive management and advanced search in such an

archive, and the FET IP project LivingKnowledge, which is developing

algorithms and methods to handle and exploit diversity, bias and

opinion on the Web. Another new project, GLOCAL, focuses on

event-based indexing of multimedia data on the web.
