Based On Agent Network Curriculum Q/A System's Research And Design

The modern long-distance teaching may cause the people under the computer network environment, not the time and the spatial limit, momentarily, completes anywhere the bidirectional interactive teaching activity, shares the outstanding teaching resources. The network Q/A dispels doubt is in the present network teaching an indispensable important component. The network Q/A's intellectualized degree becomes one of influence network quality of teaching important attributes, the network Q/A system's design and realized based on Agent already became in the current network education research and an application new hot topic, how particularly to raise the system intellectualization level the fundamental research and the technology realizes the aspect to have the big challenging.This article in elaborates the domestic and foreign modern long-distance teaching Q/A system research present situation, the correlation theories and realizes in the technical foundation, has analyzed the present domestic network Q/A system existence main flaw, like the major part Q/A system is through the email, on-line asynchronous discussion area and the message center, on-line synchronized chat-room, on-line pronunciation conference and so on artificial Q/A way realizes, does not have the design to be structurally more beneficial in the thorough discussion question environment, the support is insufficient to the intelligence, system's resources storehouse content is not very rich, Q/A system's resources storehouse and teaching system's resources storehouse separate and so on.This article proposed improves the above flaw based on the Agent network Q/A system, provided a good theoretical model in the system intellectualization aspect with to realize the plan, enabled the system to understand automatically the user question text, gave a clearer answer, and the knowledge library had the active learning ability.This article designed under the integrated development environment of Microsoft Visual Studio and realizes one by"to answer questions automatically Agent"and"the knowledge library studies Agent"for the core network Q/A system. And answers questions Agent to use the natural language processing technology automatically to realize, mainly to uses the natural language description the question to carry on the science the participle; Carries on the extraction and the corresponding weight computation after the participle key words; Intelligence matching technique and similarity computation and so on. The knowledge library studies Agent to verify Agent through the expert to be auxiliary realizes is mainly the expert answers questions; Answers questions the result to the expert to form the knowledge standardization description; Verifies through the expert enters the knowledge library; Forms the new knowledge spot.This article place of innovation: Not only the system supports the natural language to inquire, moreover provided the question confirmation to be interactive; The system also supports many kinds of question solution way, provides has the automatic characteristic man-machine interaction channel; Increased the question type judgment, answer processing and the explanation part in the question processing unit, both has guaranteed the system to a question more accurate understanding, and causes the answer which presents to be briefer and to the point; System's knowledge library has the automatic study and renewal ability.In summary, this article broke the traditional Q/A pattern control limit, has provided the method which for network environment of long-distance teaching Q/The intellectualization, facilitates quickly. Has provided the new mentality for the computer auxiliary education, its research results are helpful in enhance the network teaching the overall level, has the good theory significance and the use value.
