Abstract:

In this paper, we report on our TREC experiments with the ClueWeb09 document collection. We participated in the relevance feedback and web tracks. While our phase 1 relevance feedback runs performance 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 relevance than the rest of the collection. Future work will involve a more detailed error analysis of our experiments.
