AB The UC3M team participates in 2010 in the second ResPubliQA evaluation campaign taking partin the monolingual Spanish task. On this occasion we have completely redesigned our Question Answeringsystem, product of multiple efforts while being part of the MIRACLE team, by creating a whole newarchitecture. The aim was to gain in modularity, flexibility and evaluation capabilities that previous versionsleft pending. Despite its initial open-domain philosophy, the new system was tested by means of the JRCAcquisand EUROPARL collections on the legal domain. We submitted two runs for the participation in theparagraph selection task. The main attempts in this campaign have focused on the study of the informationneeds concerning time. Starting from implementing a base system based on passage retrieval, we addedtemporal question analysis capabilities, temporal indexing to the collection, as well as some temporal filteringand reasoning features, getting a global accuracy of 0.51. In the second run we have implemented an answeranalysis module based on n-gram analysis. The obtained results are slightly better, achieving a 0.52. Wediscuss the results found from each configuration when applied to the different temporal questions types.
