Center hyperedge (induced by source paper "using mise en scene visual features based on mpeg 7 and deep learning for movie recommendation"):
  Abstract: Item features play an important role in movie recommender systems, where recommendations can be generated by using explicit or implicit preferences of users on traditional features (attributes) such as tag, genre, and cast. Typically, movie features are human-generated, either editorially (e.g., genre and cast) or by leveraging the wisdom of the crowd (e.g., tag), and as such, they are prone to noise and are expensive to collect. Moreover, these features are often rare or absent for new items, making it difficult or even impossible to provide good quality recommendations. #R##N#In this paper, we show that user's preferences on movies can be better described in terms of the mise-en-sc\`ene features, i.e., the visual aspects of a movie that characterize design, aesthetics and style (e.g., colors, textures). We use both MPEG-7 visual descriptors and Deep Learning hidden layers as example of mise-en-sc\`ene features that can visually describe movies. Interestingly, mise-en-sc\`ene features can be computed automatically from video files or even from trailers, offering more flexibility in handling new items, avoiding the need for costly and error-prone human-based tagging, and providing good scalability. #R##N#We have conducted a set of experiments on a large catalogue of 4K movies. Results show that recommendations based on mise-en-sc\`ene features consistently provide the best performance with respect to richer sets of more traditional features, such as genre and tag.
