The invention relates to the technical field of literature retrieval. The invention discloses a literature recommendation method, device and equipment based on a double-
tower model and a medium, and the method comprises the steps: obtaining behavior data of a target user; according to the behavior data of the target user, extracting a behavior preference
feature vector of the target user, and calculating a deep representation vector of the target user based on a double-
tower model; obtaining a deep representation vector of the candidate literature based on a preset vector
database, and calculating the similarity between the deep representation vector of the target user and the deep representation vector of the candidate literature; and generating a literature recommendation
list of the target user according to the similarity. According to the method, the semantic features and the interest preference features of the user are obtained by deeply fusing the historical behavior data of the user, a literal matching category is exceeded, user requirements can be more accurately matched, and personalized recommendation is realized. And meanwhile, by utilizing the
parallel processing capability of the double-
tower model, the response speed of the recommendation
system can be increased, and the recommendation efficiency is improved.
