Community-Plattformen: Experten finden und Netzwerke organisieren (Dropping Knowledge)
von Prof. Hans Uszkoreit, DFKI, Saarbrücken

Introduction
Situation quite different for
- emerging knowledge
- knowledge in a flux
- alternative hypotheses or schools
- dynamically developing best practice
–> in these areas the dialogue between PEOPLE has always been the best way to go on
Examples : social and behavioral sciences, humanities, engineering, arts
Also in formal and natural sciences, one can find heated debates
Examples of questions that need discussion: questions on the effects of globalization, cultural tolerance vs. universal ethical culture –> multiple view
What comes together in this research project?
e-learning, web 2.0 + semantic web (noch nicht da): use of semantic metadata for knowledge repositories and use –> ontologies are already in use
Idea: dropping knowledge
- global initiative to support the free and open sharing of knowledge
- start: collection of 50000 questions worldwide (via the internet) –> user rating –> reduction to 100 questions, nomination of 112 persons
- by now: cooperation also with companies to use the process for knowledge management in companies
- results:
- different PR actions (starting with a powerful and highly exciting seed event, audiovisual media, film, exhibition)
- "dropping knowledge living library" of the questions and about 10000 answers –> connection to wikipedia, links to other sources (NGOs, poems, other organizations)
- Beiträge müssen miteinander verknüpft werden, um den einzelnen Nutzer zu leiten (sonst Problem des information overload) –> Ontologie: vieldimensionale Landkarte der relevanten Wissensdomäne, auf der die Inhalte wie Pflanzungen oder Siedlungen angeordnet werden können.
Wie kann diese Technologie in der Bidlung ausgenutzt werden?
- Fundgrube von Inhalte für Unterricht in Sozialkunde, politische Bildung, Ökonomie
- bereits Forderung nach Erweiterung (z.B. "Dossiers" (bereits zusammengestelltes Wissen zu bestimmten Themen), Wissens-Quiz)
Factors for Selection/Prioritzing
- recency, authority, rating, active use (sich darauf bezogen?), passive use, external relevance –> gehen in die Ontologie
- Durch Ontologie werden Einzelthemen unter verschiedenen Schlagworten eingeordnet.
Plans
- user participation in knowledge building (easy submission, more users)
- input of instances: organizations, people, publications, thematic links
- input of new relations: aggravating and alleviating factors
Problems
- users are overwhelmed by the number of contributions
- they cannot easily grasp the major opinions and camps
- they have to read through hundreds of postings to get a picture of what’s going on
–> new: new opinions have to be mapped according to opinion
