讲座内容简介:

Many people consider the WWW as the knowledge base or library of mankind: In general, managing this huge resource of information means to cope with natural language processing and, in particular, analysis and classification of huge amounts of documents. Although several approaches for doing so are known, they significantly differ concerning their exactness and computational costs. The major disadvantage of most of them is not to utilise the general knowledge a human reader may have. Furthermore, none of the methods is able to process and consider documents as ordered sequences of words, whereby different sequences may significantly determine a text's contents and meaning - as well as its quality. To solve these problems and to refine the capabilities of text categorisation, the concepts of text-representing centroids and evolving centroids are introduced in this talk. After presenting some necessary fundamentals, formal definitions of centroids will be given and several interesting properties discussed. Then, their application, in particular within an innovative, decentralised search engine for the WWW, is outlined.

主讲人简介:

Prof. Dr.-Ing. habil. Herwig Unger obtained his PhD degree with a thesis on Petri net transformations from the Technical University of Ilmenau in 1994, and his habilitation (DSc) with a work on large distributed systems from the University of Rostock in 2000. Since 2006, he is a full professor at Fernuniversität in Hagen and  head of its Chair of Communication Networks. His research interests are in decentralised systems and self-organisation, natural language processing as well as large-scale simulations. He has published more than 140 articles in archival journals and referred conferences, written or edited more than 25 books, respectively, and given over 35 invited talks and lectures in 12 countries.
