Label recommendation method and device and readable medium

The invention discloses a label recommendation method and device and a readable medium, and relates to the field of label recommendation. The method comprises the steps of obtaining a target account and a target resource; determining a recommendation value of a label through a label recommendation model decomposed by the tensor, the label recommendation model being composed into a core tensor anda factor matrix by the tensor, a target sub tensor in n sub tensors of the core tensor being correspondingly multiplied by the factor matrix, and the other sub tensors being 0; and determining n labels with the highest recommendation value in the label data as labels recommended to the target account. In the process of recommending the labels through the label recommendation model, the element inother sub tensors except the target sub tensor in the core tensor is 0, namely in the equality relationship, the part participating in the equality relationship in the core tensor only comprises thepart corresponding to the ta
