UMKC participated in the 2007 legal track. Our experiments focused mainly on evaluating the different query formulations in the negotiated query refinement process of legal e-discovery. For our study, we considered three sets of paired runs in vector space model and language model respectively. Our experiments indicated that although the Boolean query negotiating process was successful for the standard Boolean retrieval model, it did not make statistically significant query improvements in our
