University of Wolverhampton at CLEF 2007

Abstract

Abstract. This paper reports on the participation of the University of Wolverhampton in the Multiple Language Question Answering (QA@CLEF) track of the CLEF 2007 campaign. We approached the Romanian to English cross-lingual task with a Question Answering (QA) system that processes a question in the source language (i.e. Romanian), translates the identified keywords into the target language (i.e. English), and finally searches for answers in the English document collection. We submitted one run of our system that has achieved an overall accuracy of 14%, and a precision over non-NIL answers of 33.73%. Error analysis revealed that this low performance is mainly due to the lack of a reliable translation methodology from the source in the target language.

Exploiting Wikipedia and EuroWordNet to solve Cross-Lingual Question Answering

“…At CLEF 2007, only one system is not based on the use of MT service [50]. In this system, the authors use the ILI module of EWN for Romanian-English bilingual QA task.…”
