Experiments with ClueWeb09: Relevance Feedback and Web Tracks
Mark D. Smucker, Charles L. A. Clarke, Gordon V. Cormack · 2009
In this paper, we report on our TREC experiments with the ClueWeb09 document collection. We par-ticipated in the relevance feedback and web tracks. While our phase 1 relevance feedback run’s perfor-mance was good, our other relevance feedback and web track submissions ’ performances were lacking. We suspect this performance difference is caused by the Category B document subset of the ClueWeb09 collection having a higher prior probability of rele-vance than the rest of the collection. Future work will involve a more detailed error analysis of our ex-periments. 1
