The returned citations on a given query are re-ranked based on the ratings that team members have assigned for similar cases making use of the scoring proposed by the I-Spy system. The results from the evaluation of the proposed tool show that pre-filtering performed better than the alternative contextualization search approaches in terms of precision.
