Sumario:Question Answering (QA) has become a promising research field whose aim is to provide more natural access to the information than traditional document retrieval techniques. In essence, a QA system is a kind of search engine that allows users to pose questions using natural language instead of an artificial query language, and that returns exact answers to the questions instead of a list of entire documents. One major challenge that currently faces this kind of systems is the multilingualism. In a multilingual scenario, it is expected for a QA system to be able to: (i) answer questions formulated in various languages, and (ii) look for the answers in several collections in different languages. Evidently, multilingual QA has many advantages over standard (monolingual) QA. In particular, it allows users to access much more information in an easier and faster way. However, it introduces additional challenges caused by the language barrier.
