Study on Key Technologies of Generator of Q/A System

Automatic question-answer system is a very hot research in natural language processing realm. But it also exist some problems. The developing period of the Q/A system in different fields is too long, and the recycle rate is so low. To deal with it, the paper researches the generator of automatic Q/A system. First, the paper introduces the answer shape measure and the module of Q/A system. It brings elaborately forward the main idea of generator. Second, it puts forward the method of answer extraction and the translation method of the heterogeneous data in the automatic Q/A system. Automatic Q/A system make the corresponding answer by the principle of the maximal weigh. The sentences are regard as the basic unit of the result matching. It considerably enhances the intelligence degree of Q/A system. Finally, it gives an example of QA system.On the base of above theory and algorithms, we implement a generator of Q/A system.
