Title

¬Die Bündelung von Kleinbergs authorities und hubs in van Rijsbergens Effektivitätsmaß

Abstract

In seiner Arbeit "Authoritative Sources in a Hyperlinked Environment" (1999) prägt Jon M. Kleinberg die Begrifffe 'authority' und 'hub'. Auf dieser Basis analysiert die folgende Arbeit, inwieweit diese Termini den von Salton/McGill geprägten Begriffen Precision und Recall entsprechen. Trifft dies zu, dann können hub and authority gemäß van Rijsbergens (1979) Effektivitätsmaß berechnet werden, was den optimalen Einstieg in einen Themenbereich eröffnen würde.
