Research And Realization Of Intelligence Answer System Facing Distance Education

With the popularization of the distance education on Internet, answering questions of distance learning becomes one of the focuses that people pay close attention to. The distance education is a kind of education by learning courses. The question that students meet in learning process may be the doubt of focal point and difficult point of course. For improving the quality of teachings answering the students' doubt, intelligence answer system needs to be set up.The paper adopts natural language processing technology, is based on B/S mode three-hierarchy system structure, utilizes AI language visual prolog as developing tool, brings forward a sort of intelligence answer system model that supports natural language processing in the limited domain, and makes analysis and discussion to its pivotal technologies and assistant measure, and realizes part of the system. The system obtains semantic analysis result by carrying on automatic participle processing,standardization processing and unitary processing to user's question description, then on the basis of that finds the suited results to feed back to user by querying course repository.The paper first makes a compare between domestic intelligence answer system and foreign intelligence answer system, points out that domestic intelligence answer system is in defect of the support of advancing technologies. Next, the paper expounds the theory of natural language processing technology, presents general design scheme of intelligence answer system, and makes research and realization to its pivotal technologies and system. Then, the paper carrys through example tests to the system. Finally, the paper also points out application foreground and development direction of Intelligence Answer System.
