Multi-channel recall recommendation method and device, electronic equipment and medium

The embodiment of the invention provides a multipath recall recommendation method and device, electronic equipment and a medium, and belongs to the technical field of computation.The multipath recall recommendation method specifically comprises the steps of preproessing an initial data set to obtain a to-be-detected data set; generating first tags corresponding to all the subject matters according to the content data, and generating second tags corresponding to the target user according to the historical behavior data; respectively calculating the similarity between the data corresponding to all the first tags; recalling a candidate set corresponding to the target user according to the similarity and the second label; and sorting the candidate sets to obtain a target set. Through the scheme of the invention, different types of initial data are processed to obtain the classification data, the corresponding labels are generated, then the similarity between the data corresponding to the first label is calculated
