基于文本的情感感知推荐

Text-based Emotion Aware Recommender

John Kalung Leung, Igor Griva, William G. Kennedy

摘要:

我们应用用户情感向量(UVECs)和电影情感向量(MVECs)的概念作为情感感知推荐系统的构建组件。我们建立了一个比较平台,由五个基于内容的过滤算法和协同过滤算法。我们采用了一个Tweets情感分类器,通过电影概述对电影的情感特征进行分类。我们构建MVEC从电影的情绪配置文件。我们跟踪用户的电影观看历史,通过取用户观看的所有电影的所有MVEC的平均值来制定UVEC。利用MVEC,我们建立了一个情感感知推荐器作为比较平台的算法之一。我们评估了这些推荐器生成的前N个推荐列表,发现情感感知推荐器的前N个列表显示了意外发现的推荐。

英文摘要:

We apply the concept of users' emotion vectors (UVECs) and movies' emotion vectors (MVECs) as building components of Emotion Aware Recommender System. We built a comparative platform that consists of five recommenders based on content-based and collaborative filtering algorithms. We employed a Tweets Affective Classifier to classify movies' emotion profiles through movie overviews. We construct MVECs from the movie emotion profiles. We track users' movie watching history to formulate UVECs by taking the average of all the MVECs from all the movies a user has watched. With the MVECs, we built an Emotion Aware Recommender as one of the comparative platforms' algorithms. We evaluated the top-N recommendation lists generated by these Recommenders and found the top-N list of Emotion Aware Recommender showed serendipity recommendations.
