Experiments with the Negotiated Boolean Queries of the TREC 2008 Legal Track

Abstract

We analyze the results of several experimental runs submitted for the TREC 2008 Legal Track. In the Ad Hoc task, we found that rank-based merging of vector results with the reference Boolean results produced a statistically significant increase in mean F1@K and Recall@B compared to just using the reference Boolean results. In the Relevance Feedback task, we found that the investigated relevance feedback technique, when merged with the reference Boolean results, produced some substantial increases in Recall@Br without any substantial decreases on individual topics.
