Title: "Fully decentralised search engines: just a dream?"

Herwig Unger and Mario Kubek, Chair of Communication Networks
FernUniversität in Hagen, 58084 Hagen, Germany


Big, centralised web search engines seem to be the perfect tools, to
find any information at any location in the WWW within just a few
moments. The first part of the talk intends to show, why Google
and Co. anyhow will not be the future of information management
in the net.
The second, main part of the talk will deal with recently developed,
new methods,  which can later result in the construction of a fully
decentralised search engine. Therefore, different methods of
modern text mining are used to construct locally working search
agents and search support tools, which have access to personal
data and search histories and can process feedback from the
users as well. After that, is is intended to show, that advances
in decentralised systems (namely P2P-based systems), self-
organisation and structure building are the fundamentals to
organise documents and implement fast, scalable but fully
decentralised search algorithms.

Some demonstrations of recent tools will conclude the talk.    


Prof. Dr.-Ing. habil. Herwig Unger got his PhD with a work on Petri Net transformation in 1994 from the
Technical University of Ilmenau and his habilitation with a work on large distributed systems from the
University of Rostock in 2000. Since 2006, he is a full professor at the FernUniversität in Hagen and the
head of the Chair of Communication Networks. His research interests are in self-organization, adaptive
and learning systems, Internet algorithms and simulation systems.

Dr.-Ing. Mario Kubek is a researcher at the Chair of Communication Networks of the FernUniversität in Hagen.
He received his PhD in 2012 with a thesis on locally working agents to improve the search for web documents.
His research focus is on natural language processing, text mining and semantic information retrieval in large
distributed systems. His further research interests include topic and trend detection in diachronic text corpora
and contextual information processing in mobile computing environments.

Colloquium coordinators are Prof.dr. M. Aiello (e-mail : M.Aiello ) and
