Abstract
Question Answering (Q&A.) systems, unlike other Information Retrieval (IR) systems, aim at providing directly the answer to the user, and not a list of documents in which the correct answer may be found. Our system is based on a data warehouse and provides composite answers made of a dataset and the corresponding chart visualizations. The question translation step is based on a new proposal for surface patterns that incorporate business semantic as well as domain-specific knowldege allowing a better coverage of questions.
