AnswerFinder in TREC 2003

In this our first participation in TREC we have focused on the passage task of the question answering track. The main aim of our participation was to test the impact of various types of linguistic information in a simple question answering system. In particular, we have tested various combinations of word overlap, grammatical relations overlap, and overlap of minimal logical forms in the final scoring module of the system. The results indicate a small increase of accuracy with respect to a baseline system based on word overlap. Overall, given the short time available for developing the system, the results are satisfactory and equal or surpass the median.
