Abstract

The University of Melbourne carried out experiments in the Terabyte and Web tracks of TREC 2004. We applied a further variant of our impact-based retrieval approach by integrating evidence from text content, anchor text, URL depth, and link structure into the process of ranking documents, working toward a retrieval system that handles equally well all of the four query types employed in these two tracks. That is, we sought to avoid special techniques, and did not apply any explicit or implicit query classifiers. The system was designed to be scalable and efficient.
