The invention provides a neural 
collaborative filtering model recommendation method based on 
lambda Mart, and the method comprises the following steps: S1, inputting 
user information which comprises user basic information and movie comment information, and the movie comment information comprises scored movie information and unscored movie information; S2, enabling the embedding layer to map the 
user information into a user 
feature vector, and mapping the movie comment information into a movie 
feature vector; S3, inputting the user 
feature vector and the movie feature vector into a neural 
collaborative filtering model, extracting high-order feature information, and extracting sorting information at the same time; and S4, 
processing the high-order feature information and the sorting information to obtain a recommendation result, and outputting the recommendation result. According to the method, an LMNCF model is put forward, a neural 
collaborative filtering model is improved, implicit high-order feature information is extracted through nonlinear feature 
processing of a multi-layer 
perceptron, sorting information is extracted through a 
lambda Mart personalized 
sorting algorithm, and recommendation is more accurate.
