Abstract:

For our participation in the Batch Task of the TREC 2009 Legal Track, we produced several retrieval sets to compare experimental Boolean, vector, fusion and relevance feedback techniques for e-Discovery requests. In this paper, we have reported not just the mean scores of the experimental approaches but also the largest per-topic impacts of the techniques for several measures. The experimental automatic relevance feedback technique was found to attain a statistically significant gain over the reference Boolean result in both the mean PrecisionB and F1K measures.
