Abstract
A previous version of AliQAn participated in the CLEF 2005 Spanish Monolingual Question Answering task. For this year’s run, to the system are added new and representative patterns in question analysis and extraction of the answer. A new ontology of question types has been included. The inexact questions have been improved. The information retrieval engine has been modified considering only the detected keywords from the question analysis module. Besides, many PoS Tagger and SUPAR errors have been solved and finally, dictionaries about cities and countries have been incorporated. To deal with Cross–Lingual tasks, we employ the BRILI system. The achieved results are overall accuracy of 37.89% for monolingual and 21.58% for bilingual tasks.
This research has been partially funded by the Spanish Government under project CICyT number TIC2003-07158-C04-01 by the Valencia Government under project number GV06/161 and by the University of Comahue under the project 04/E062.
