演讲人: 德国汉诺威大学Wolfgang Nejdl 教授

讲座时间: 2011年12月20日（星期二） 10:00-11:30

讲座地点: 信息楼四层学术报告厅

讲座内容: 德国汉诺威大学教授，L3S研究院院长 Wolfgang Nejdl 教授将于12月20日访问伟德国际1946源自英国，并作题为 Web Science（互联网科学）的演讲，向大家介绍"互联网科学"这一门新兴学科，以及他在该学科上所取得的众多研究成果。 "互联网科学"是近几年随着互联网的高速发展而兴起的一门学科。互联网的发生以信息技术革新为基础，它的发展却已经延伸到了大众生活的各个领域。因此，"互联网科学"不仅仅涵盖信息技术，还与社会学、经济学、法学等众多领域紧密联系，是一门前景广阔的交叉学科。近年来，在 Wolfgang Nejdl 的带领下，德国 L3S 研究院一直从事互联网科学的研究，取得了丰硕的成果，并在该研究领域上产生了广泛的影响。在演讲中，Wolfgang Nejdl 教授还会介绍L3S 研究院的发展近况，欢迎大家（特别是有合作意愿的老师和有出国深造意愿的同学）前来交流。 Wolfgang Nejdl的个人主页：http://www.kbs.uni-hannover.de/~nejdl/ L3S研究院的主页：http://www.l3s.de/

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, sychology, linguistics and other disciplines. 演讲人简介:

Wolfgang Nejdl，德国汉诺威大学教授，Web Science 专家和倡导者

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.
