The embodiment of the invention relates to a user interest mining method and system, electronic equipment and a medium. The method comprises the following steps: splitting a behavior sequence of a user; extracting a posting sequence of an object user in the social relation sequence of the user; extracting four sequences of post ID, post category, posting time and post author ID from each sequence in the split sequences and the extracted posting sequences; inputting four sequences of post ID, post category, posting time and post author ID extracted for each sequence into a first deep neural network to obtain a group of vectors A for each sequence; taking a currently trained post as input, and performing attention mechanism operation on a group of vectors A for each sequence to obtain a post-attention vector A '; inputting the vector A'into a training model to obtain a pre-estimated score of a currently trained post, adjusting the training model according to the pre-estimated score, and taking ...
