In the last decade, QA has become an important subfield of NLP and IR. Its development track, i.e. accelerating research via systematical and large scale evaluation, and some successful experiences, such as the effectiveness of partial-parsing techniques based on character surface and the importance of fast NLP tools, have made it a great and most important impetus to the research of NLP.
