Abstract

The present invention proposes an algorithm for automatically generating movie labels based on film reviews. The algorithm in the present invention fully considers the missing problem existing in the data set of currently labeled movies. First, an unsupervised algorithm with weights is used to automatically train Set complementary labels. At the same time, the present invention also fully considers the relationship between the similarity of the attributes of the two movies and the similarity of the labels, and predicts the mapping from the attributes to the similarity of the labels with the method of machine learning, instead of using simple similarities such as cosine Similarity calculates a rough similarity relationship. Finally, after using the traditional K-nearest neighbor algorithm to obtain multiple sets of candidate labels, this method does not use simple evaluation criteria to sort and select the label set, but uses a graph algorithm based on the co-occurrence relationship of labels to determine the order of candidate labels, so that Decide on the final label set.

Description

technical field

[0001] The invention relates to the field of artificial intelligence, and more specifically, to a method for automatically generating movie labels based on movie reviews. Background technique

[0002] Because of its rich elements, movies quickly become one of the necessary leisure ways in people's daily life. The market for movies is getting bigger and bigger, and there are more and more types of movies. A wide variety of movies and the length of the movie make it impossible for users to browse a movie in its entirety. For upcoming movies, a better way for users to know about a movie usually includes introduction, trailer, other users’ reviews and movie tags. But for some older or less popular movies, users usually only know the introduction and movie tags. Therefore, the social tags of movies are of great significance. They can help recommendation systems improve the accuracy of movies recommended for users, help platforms that provide movie information fi...
