一种新的基于多视觉内容分析和半监督增强的电影推荐方法

A Novel Approach Based on Multi-View Content Analysis and SemiSupervised Enrichment for Movie Recommendation

  • 摘要: 尽管现在已经有许多电影推荐的系统基于点击和标签等信息,但是很少有工作基于电影的多媒体内容,这些多媒体内容对于发现用户在视觉和音乐上面的喜好能够提供潜在的信息。本文分析三种多媒体类型(图片,文本,音频)的内容并在此基础上提出了一种新的多视图半监督的电影推荐方法。每种媒体分别作为电影的一个视图,三个视图的内容相结合来预测用户对一个新电影的评分。另外,该方法还考虑了具有有限的评分记录的临时用户。当临时用户提供很少的评分记录的时候,算法采用一种半监督的方式增强用户。实验显示多媒体内容能够更全面的提供用户喜好。不同的媒体类型可以相互补充,提高推荐系统的性能。半监督的增强方法也显示了对于临时用户进行电影推荐的有效性。

     

    Abstract: Although many existing movie recommender systems have investigated recommendation based on information such as clicks and tags, much less efforts have been made to explore the multimedia content of movies, which has potential information for the elicitation of the user's visual and musical preferences. In this paper, we explore the content from three media types (image, text, audio) and propose a novel multi-view semi-supervised movie recommendation method, which represents each media type as a view space for movies. The three views of movies are integrated to predict the rating values under the multi-view framework. Furthermore, our method considers the casual users who rate limited movies. The algorithm enriches the user profile with a semi-supervised way when there are only few rating histories. Experiments indicate that the multimedia content analysis reveals the user's profile in a more comprehensive way. Different media types can be a complement to each other for movie recommendation. And the experimental results validate that our semi-supervised method can effectively enrich the user profile for recommendation with limited rating history.
