摘　　要：为了解决传统英语教学资源挖掘系统存在的挖掘精度与挖掘效率较低的问题,提出并设计一种基于云计算的英语教学资源快速挖掘系统。系统硬件部分包括英语教学资源管理模块与挖掘模块,以实现系统的挖掘功能。系统软件部分利用自适应分割模型分割英语教学资源语义特征,并凭借概率向量图分配法匹配教学资源的自相关特征,最后采用自适应级联检索控制方法完成英语教学资源的高效挖掘。实验结果表明,与传统挖掘系统相比,所设计系统能够有效提高挖掘精度,并降低挖掘耗时。In order to solve the problems of low mining accuracy and efficiency in the traditional English teaching resource mining system,a fast mining system of English teaching resources based on Cloud Computing is proposed and designed.The hardware part of the system includes English teaching resource management module and mining module to realize the mining function of the system.In the software part of the system,the adaptive segmentation model is used to segment the semantic features of English teaching resources,and the probability vector graph allocation method is used to match the autocorrelation features of teaching resources.Finally,the adaptive cascade retrieval control method is used to mine English teaching resources efficiently.The experimental results show that compared with the traditional mining system,the designed system can effectively improve the mining accuracy and reduce the mining time.
