Abstract

Following last year’s participation in the monolingual question answering (QA) track of CLEF, where Priberam’s QA system has achieved state-of-the-art results, this year we decided to take part in both Portuguese and Spanish monolingual tasks, as well as in two bilingual (Portuguese-Spanish and Spanish-Portuguese) tasks of QA@CLEF. This paper describes the improvements and changes implemented in Priberam’s QA system since last CLEF participation, detailing the work involved in its cross-lingual extension and discussing the results of the runs submitted to evaluation.
