MIRACLE at the Spanish CLEF@QA 2006 track (1): abstract

We describe the prototype QA system built by MIRACLE group, a group composed by three Madrid universities and the spin-off, DAEDALUS. The system is an elaboration of our last year system with several improvements in question analysis and NERC components. We submitted two runs for the Spanish runs with different strategies to use NE in passage selection and answer ranking. Results show that a recall oriented approach obtain more accurate results. A detailed analysis of errors and a preliminary comparison with our last year system are also discussed.
