AnswerFinder in TREC 2003

Research output: Chapter in Book/Report/Conference proceedingConference proceeding contribution

Abstract

In this our rst 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 lin- guistic information in a simple ques- tion answering system. In particular, we have tested various combinations of word overlap, grammatical relations overlap, and overlap of minimal logi- cal forms in the nal 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.
