Abstract: This study, with the methods of literature analysis and system analysis, explored the technical and tactical knowledge representation, the platform reasoning mechanism and the resource library structure of the sports event, the link of research & development platform.And it also constructed the research-training-learning platform.The results showed that the technical and tactical knowledge can be divided into two categories:explicit and implicit.The former is represented by object-oriented method while the latter by artificial neural network method.The reasoning mechanism of the research-training-learning platform consisted of relevance, converse, neural network and decision tree.The resource base is composed of the dynamic database, the game information database, the competitor information base, the analysis database, the literature database and the software library.The application showed that the platform integrated a variety of information and software resources, thus it can provide an effective decision support for teaching, training and research.
