摘要/Abstract

摘要：

为提高Web资源推荐的准确度,提出基于本体的Web资源个性化推荐算法(BO-RM)。设计Web资源主题抽取算法和相似性度量方法,利用本体语义推理机制实现资源聚类,在推荐过程中通过实时分析用户浏览行为捕获用户个性化偏好的变化,动态实时推荐内容。与基于情境的协同过滤算法（CFR-RM）和基于模型的个性化预测算法（BM-RM）进行对比,结果显示BO-RM的时间开销相对稳定,在平均排序倒数(MRR)和平均准确率(MAP)上均取得了较好的效果。实验结果表明:BO-RM离线完成海量Web资源的分析聚类,有效提高了运行效率,实用性比较强；BO-RM实时捕捉用户兴趣变化,动态更新推荐列表,更加贴近用户的真实需求。

Abstract:

To improve the accuracy of recommended Web resources, a personalized recommendation algorithm based on ontology, named BO-RM, was proposed. Subject extraction and similarity measurement methods were designed, and ontology semantic was used to cluster Web resources. With a user's browser tracks captured, the tendency of preferences and recommendation were adjusted dynamically. Comparison experiments with collaborative filtering algorithm based on situation named CFR-RM and personalized prediction algorithm based on model were given. The results show that BO-RM has relatively stable overhead time and good performance in Mean Reciprocal Rank (MRR) and Mean Average Precision (MAP). The results prove that BO-RM improves the efficiency by using offline data analysis for large Web resources, thus it is practical. In addition, BO-RM captures the users' interest in real-time to updates the recommendation list dynamically, which meets the real needs of users.
