英语教学资源库系统中个性化检索模块的设计

Individualized Search Model in Database System of English Teaching Resources

针对目前教学资源服务中普遍存在的海量教学资源与用户个性化需求之间的矛盾，在基余校园网的英语教学资源库系统中建立了一个教学资源个性化检索模型，该模型把基于网络的个性化信息服务引入英语教学资源体系，尊重用户中存在的差异。实验表明：该模型能有效地提高英语教学资源服务中个性化检索的查全率和查准率

There is a common contradiction between individualized demands and the masses of English teaching resources， In order to find a way out， an individualized search model of English teaching resources(ISMTR) was designed， which employs the individualized information service on the network into teaching. It defers to the differences of users， studies their habits and interest. By filtering the teaching resources， the precise searches and recommendation can be made. It also conducted an experiment to verify the feasibility. It was demonstrated that ISMTR can effectively improve the precision and recall of the searching in English teaching resources.
