摘　　要：数字化教育的发展促使学习资源快速增长,但由于资源整合系统的针对性较差,用户查找费时较长。为此,提出基于HDFS的大学英语在线课程资源整合系统设计。依据HDFS系统结构特征选取具有强大功能的采集器与储存器等硬件设施。采用信息熵理论获取课程资源特征方程,按照该特征构建资源整合集合,完成系统软件设计。实验结果证明,该系统能够提高用户资源查找准确率,减少查找时间,提高用户满意度。The development of digital education promotes the rapid growth of learning resources,but due to the poor pertinence of the resource integration system,user search time is quite long.In order to solve this problem,a resource integration system is designed for college English online courses based on HDFS.According to the structural characteristics of the HDFS system,hardware facilities such as collectors and storage devices with powerful functions are selected to realize the hardware design.The information entropy theory is used to obtain the characteristic equation of curriculum resources,the resource integration set is constructed according to this characteristic,and the system software design is completed.Experimental results prove that the system can improve the accuracy of user resource search,reduce search time,and improve user satisfaction.
