This paper presents a roadmap of current promising research tracks in question answering with a focus on knowledge acquisition and reasoning. We
show that many current techniques developed in the frame of text mining
and natural language processing are ready to be integrated in question answering search systems. Their integration opens new avenues of research for
factual answer finding and for advanced question answering. Advanced question answering refers to a situation where an understanding of the meaning of
the question and the information source together with techniques for answer
fusion and generation are needed.
