This paper describes the work done by Priberam in the development of a question answering (QA) system for Portuguese. The system was built using the company’s natural language processing (NLP) workbench and information retrieval technology. Special focus is given to question analysis, document and sentence retrieval, as well as answer extraction stages. The paper discusses the system’s performance in the context of the QA@CLEF 2005 evaluation.
