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 fullydecentralised 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 theusers as well. After that, is is intended to show, that advancesin decentralised systems (namely P2P-based systems), self-organisation and structure building are the fundamentals to organise documents and implement fast, scalable but fullydecentralised 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.

The COVID-19 restrictions have been tightened once again. To many staff members and students, this feels like a step backwards. We chatted with members of the Board of the University Jouke de Vries, Cisca Wijmenga and Hans Biemans about managerial...
Biological clocks have sizeable effects on the performance of elite athletes. This conclusion was drawn by chronobiologists from the University of Groningen after studying the times achieved by swimmers in four different Olympic Games. Shifting the...
