Abstract

Der Austausch von Wissen kann in Peer-to-Peer-Systemen effizient gestaltet werden und hat damit ein großes Anwendungspotenzial innerhalb von Unternehmen und für virtuelle Organisationen im Allgemeinen. Dieser Beitrag konzentriert sich nicht auf Systeme die den Austausch unstrukturierten Daten (wie Multimediadaten) unterstützen, sondern auf Ansätze die den Austausch von semantischen Wissensstrukturen in Peer-to-Peer-Systemen unterstützen. Das Wissen auf den einzelnen Peers wird in solchen Systemen mit Hilfe einer Ontologie beschrieben. Insbesondere können in diesen Systemen die semantischen Wissensstrukturen dazu benutzt werden, Anfragen effektiver innerhalb des Netzwerkes zu verteilen und gleich gesinnte Nutzer zusammenzuführen. In diesem Zusammenhang präsentieren wir einen Algorithmus für das effektive Routing von Anfragen in selbstorganisierenden Peer-to-Peer-Systemen, welches proaktiv gesendete Werbungen und passiv aufgesammeltes Wissen kombiniert, um lokale Indizes von entfernten Peers aufzubauen. Der Ansatz wurde im Bibster-System prototypisch umgesetzt und in einer Fallstudie im Bereich bibliographischer Informationen evaluiert.
