RMIT University at TREC 2004

RMIT University participated in two tracks at TREC 2004: Terabyte and Genomics, both for the first time. This paper describes the techniques we applied and our experiments in both tracks, and discusses the results of the genomics track runs; the terabyte track results are unavailable at the time of manuscript submission. We also describe our new zettair search engine, in use for the first time ...

Indri at TREC 2004: Terabyte Track

This paper provides an overview of experiments carried out at the TREC 2004 Terabyte Track using the Indri search engine. Indri is an efficient, effective distributed search engine. Like INQUERY, it is based on the inference network framework and supports structured queries, but unlike INQUERY, it uses language modeling probabilities within the network which allows for added flexibility. We des...

Indri at TREC 2005: Terabyte Track

This work details the experiments carried out using the Indri search engine during the TREC 2005 Terabyte Track. Results are presented for each of the three tasks, including efficiency, ad hoc, and named page finding. Our efficiency runs focused on query optimization techniques, our ad hoc runs look at the importance of term proximity and document quality, and our named-page finding runs invest...
