Question and answer system, which is a full-text retrieval system based on dynamic knowledge library, is an important segment of remote education platform. Information retrieval technique is a key technology to make the success of Intelligent Question Answering System. The paper gave research and analysis on the inverted index technology and adopted the improved TFIDF weighting formula in order to...
In past twenty years, as the rapid growth of Internet application, network education has grown a main part of current education. At the same time, semantic-based network educational resource became an important research field in computer education technology and AI. So far, however, there is a serious of bottlenecks in the progress of their applications, e. g. the criterion of web resource is not...
The purpose of an intellectual answering system is that the system can answer questions automatically. To construct this kind of system, it must collect and store questions and answers organically. The intelligent Q&A system will contain a Q&A library, which is built through the semantic understanding of natural language technology and it will be growing automatically during students question...
On the basis of some research work on the educational game sites, we introduce an intelligent system for educational game resource discovery and define a concept of game-metadata structure. It will strive to organize educational games all over the internet and provide a new way of thinking in building game resource database. In this paper, both of the key technologies and the function modules are...
With the development and updating of the artificial intelligence techniques, some theories concerning artificial intelligence, especially in agent techniques, are applied to remote teaching system to open the new development space. The paper designs a remote Internet teaching system model on the basis of multi-agent techniques. And then describes each module functions and methods in the model and...
Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. It can visualize the real earth and represent historical phenomena in digital way by using the large amount of data of the earth, and utilizing the computer techniques, image...
