Abstract

Ziel der US-amerikanischen TREC (Texte REtrieval Conference) Initiative ist es, zum einen Standard-Kollektionen von Teten zu erstellen, auf deren Basis verschiedene Retrieval-Ansätze verglichen werden können. Zum anderen sollen Kollektionen einer Grösse aufgebaut werden, die realistischen Anwendungen nahe kommen. Damit soll das alte Vorurteil der Untauglichkeit neuerer IR-Methoden (bzgl. Effizienz und Effektivität) für größere Darenbasen widerlegt werden.
