Abstract: In this paper,super computer Waston's win,in man-machine war,we discusses the nspiration of researching artificial intelligence.And compared to Galaxy computer,Watson's computing power is still relatively weak.Watson may not enter the super-computing power top 100,But one thing can Waston(quiz) to the best dry.Watson's strength nor the Deep Blue chess system,But the challenges of common sense is not worse under chess,or even better.This is a new milestone in artificial intelligence..
