The Role of Anchor Text in ClueWeb09 Retrieval.
Vo Ngoc Anh, Alistair Moffat · 2010
Abstract: This report describes the work done at The University of Melbourne with the ClueWeb09 data corpus for the Web Track of TREC-2009 and TREC-2010, and for the Session Track of TREC-2010. We found that the impact-based retrieval model works well for the corpus, and that, along with some other factors, the use of an anchor text collection significantly boosts the retrieval effectiveness. 1
