Abstract

This paper deals with the AliQAn QA system in the multilingual (English - Spanish) task. It highlights the translation module of the QA system by applying two methods: the first one based on logic forms, and the other on machine translation techniques. Moreover, the system is able to solve the anaphora resolution problem by applying linguistic techniques. According to the results, machine translation techniques are a bit better than techniques based on logic forms in the performance of the question translation.
