Abstract

There are currently many different types and dispersed online educational resources, which inconvenience users and result in a low utilisation rate of resources. As a result, a new approach is required to realise the integration and recommendation of educational resources. This paper examines the intelligent integration and recommendation of online learning resources for English language and literature majors based on CF. The development of online English language and literature education resources is currently in the process of being discussed, and some flaws in the process are being examined in this paper. The creation and incorporation of a network education resource database are proposed as some strategies and recommendations. The information entropy method is employed to address the cold start problem brought on by the data sparseness of new users and new projects in CF. While this is happening, the recommendation process's similarity algorithm is being enhanced. This algorithm's decision support accuracy has been found to be 96.01% after extensive testing. Its accuracy is roughly 8% better than that of conventional CF, which has a precision of 8%. The results demonstrated a degree of accuracy in the improved algorithm.

摘要

目前存在着许多不同类型和分散的在线教育资源,这给用户带来了不便,导致资源利用率低。因此,需要一种新的方法来实现教育资源的整合和推荐。本文基于 CF 研究了英语语言文学专业在线学习资源的智能整合和推荐。目前正在讨论在线英语语言文学教育资源的开发,本文研究了该过程中的一些缺陷。提出了创建和整合网络教育资源数据库的策略和建议。该方法采用信息熵法解决 CF 中新用户和新项目数据稀疏带来的冷启动问题。在此过程中,增强了推荐过程的相似性算法。经过广泛测试,发现该算法的决策支持准确率为 96.01%。其精度比传统 CF 高约 8%,传统 CF 的精度为 8%。改进后的算法结果具有一定的准确性。
