1、 摘要摘要 进入大数据的时代，信息的产生、加工、传播变得越来越容易，计算 机已经深入到人们现代生活的方方面面，在教育领域，智能教学系统作为 一种辅助教学的手段逐渐成为 E-Learning 领域众多学者的研究重点，但多 数智能教学系统缺乏有效的学习资源推荐机制，使得用户无法准确地寻找 到满足自身学习需求的学习资源，最终导致用户学习兴趣下降，系统教辅 作用无法得到充分地发挥。 个性化推荐是缓建信息过载的方法之一，为了解决在海量题库中为学 生提供个性化资源推荐的问题，对于传统的基于用户的协同过滤和基于内 容的协同过滤，存在很多弊端，难以满足用户的需求。对于基于用户的协 同过滤推荐的原则，如果一个用
2、户没有相同喜好的朋友，那该算法的推荐 效果总是不令人满意；对于基于内容的协同过滤推荐的原则，就是假设指 用户会喜欢和他以前喜欢的东西是比较相似的，如果不是相似的，用该算 法做出准确的推荐的可能性非常低。 针对以上现象，为了能够更好的达到个性化推荐系统的效果，在相关 理论的指导下，本文提出了基于记忆的过滤和基于规则的过滤两种推荐算 法，最终实现习题系统对于学生用户的个性化推荐，以避免传统推荐系统 因忽略资源本身蕴涵信息而产生的无关推荐，为智能教学系统中的应用提 供一种新的发展思路。 关键词关键词：个性化推荐，基于用户的协同过滤，基于内容的协同过滤，基于 规则的过滤 Abstract Entere
