Abstract :
In this paper, a Chinese question answering system is designed and implemented. Firstly, the overall structure of Chinese question answering system is introduced. Secondly, the question classification algorithm based on improved rules and answer extraction algorithm using semantic matching similarity comparison based on dependency trees are presented. Finally, experiments and tests on the system are carried out, results are analyzed and shown that the system is effective.
