The main function is to make up for the deficiency of leaderboard recommendation; Secondly, it is used to guide users to focus on topics or themes. Avoid short-term hot topics as low-quality hot topics and enrich content diversity.
Personalized recommendation is commonly used in two ways:
A. On the basis of user recommendation, classify according to user's behavior information, and recommend a kind of content that users like to users who have never seen the content.
B. Based on the recommendation of items, find similar content and recommend it to the current user according to the currently browsed content.
Douban is recommended in both ways.
