Abstract

This paper presents a system for real-time, open-domain question answering on the Web of documents written in Portuguese, prepared to handle factual questions and available as a freely accessible online service. In order to deliver candidate answers to input questions phrased in Portuguese, this system resorts to a number of shallow processing tools and question answering techniques that are specifically geared to cope with the Portuguese language.
