视频推荐系统中基于评论的用户/电影偏好特征挖掘

Mining User/Movie Preferred Features Based on Reviews for Video Recommendation System

Xuan-Son Vu, Seong-Bae Park

摘要:

在这项工作中,我们提出了一种基于评论挖掘用户偏好和推荐的方法。关于推荐问题已经有了很多研究。然而,大多数的研究都超越了用户生成的一个方面--内容,如用户评分、用户反馈等来陈述用户偏好。在一个方面存在的问题是缺乏挖掘来陈述用户偏好。作为示范,在协同过滤推荐中,我们试图找出拥挤用户的偏好趋势,然后使用该趋势来预测当前用户的偏好。因此,真实的用户偏好与拥挤人群的趋势之间存在差距。此外,由于用户经常评论产品的各个方面,因此可以通过挖掘用户评论来解决用户偏好。为了解决这个问题,我们主要集中在挖掘用户评论中的产品方面和用户方面,以直接表示用户的偏好。对于冷启动项目问题,我们还考虑了社会网络分析。针对冷启动用户问题,采用协同过滤算法。该框架足够通用,可以应用于不同的推荐领域。从理论上讲,我们的方法将实现显着的增强。

英文摘要:

In this work, we present an approach for mining user preferences and recommendation based on reviews. There have been various studies worked on recommendation problem. However, most of the studies beyond one aspect user generated- content such as user ratings, user feedback and so on to state user preferences. There is a prob- lem in one aspect mining is lacking for stating user preferences. As a demonstration, in collaborative filter recommendation, we try to figure out the preference trend of crowded users, then use that trend to predict current user preference. Therefore, there is a gap between real user preferences and the trend of the crowded people. Additionally, user preferences can be addressed from mining user reviews since user often comment about various aspects of products. To solve this problem, we mainly focus on mining product aspects and user aspects inside user reviews to directly state user preferences. We also take into account Social Network Analysis for cold-start item problem. With cold-start user problem, collaborative filter algorithm is employed in our work. The framework is general enough to be applied to different recommendation domains. Theoretically, our method would achieve a significant enhancement.
