论文摘要
在当今的世界中,可以消费诸如电子书,电影,视频和文章之类的丰富数字内容。审查所有可访问的内容并确定下一步要观看的内容是令人生畏的。因此,数字媒体提供商希望利用这种混乱并解决它以增加用户参与度,最终导致更高的收入。内容提供商经常利用推荐系统作为对这些信息过载来对抗的有效方法。本文集中于开发推荐电影的合成方法。传统上,电影推荐系统使用协作过滤,它利用用户与媒体的互动或基于内容的过滤,它利用了电影的可用元数据。技术进步还引入了一种整合这两个系统的混合技术。但是,我们的方法仅处理基于内容的建议,通过基于内容相似性指标的排名算法进一步增强它。促成排名的三个指标是元数据,视觉内容和用户评论的相似性。我们使用文本矢量化,然后使用元数据的余弦相似性,预先训练的VGG19提取功能,然后进行视觉内容的K-均值聚类,以及对用户评论的情感进行比较。这样的系统使观众能够了解“感觉”相同的电影。
In today's world, abundant digital content like e-books, movies, videos and articles are available for consumption. It is daunting to review everything accessible and decide what to watch next. Consequently, digital media providers want to capitalise on this confusion and tackle it to increase user engagement, eventually leading to higher revenues. Content providers often utilise recommendation systems as an efficacious approach for combating such information overload. This paper concentrates on developing a synthetic approach for recommending movies. Traditionally, movie recommendation systems use either collaborative filtering, which utilises user interaction with the media, or content-based filtering, which makes use of the movie's available metadata. Technological advancements have also introduced a hybrid technique that integrates both systems. However, our approach deals solely with content-based recommendations, further enhancing it with a ranking algorithm based on content similarity metrics. The three metrics contributing to the ranking are similarity in metadata, visual content, and user reviews of the movies. We use text vectorization followed by cosine similarity for metadata, feature extraction by a pre-trained VGG19 followed by K-means clustering for visual content, and a comparison of sentiments for user reviews. Such a system allows viewers to know movies that "feel" the same.
