More Reflections on "Aboutness" TREC-2001 Evaluation Experiments at Justsystem
The TREC-2001 Web track evaluation experiments at the Justsystem site are described with a focus on the "aboutness" based approach in text retrieval. In the web ad hoc task, our TREC-9 approach is adopted again, combining both pseudo-relevance feedback and reference database feedback but the setting is calibrated for an early precision preferred search. For the entry page finding task, we combined techniques such as search against partitioned collection with result fusion, and attribute-value basis re-ranking. As post-submission experiments, distributed retrieval against WT10G is examined and two different database partitioning and three database selection algorithms are combined and evaluated. Keywords Aboutness, pseudo-relevance feedback, reference database, fusion, attribute-value basis re-ranking, distributed retrieval, collection partitioning, database selection.
