User tag identification method and device based on session scene

The invention relates to a user tag identification method and device based on a session scene, computer equipment and a storage medium. The method comprises the steps of performing text preprocessing on a dialogue short text to obtain a minimum semantic unit, wherein the minimum semantic unit comprises a plurality of first-level labels; inputting the minimum semantic unit into a pre-trained first-level label identification model, wherein the first-level label identification model comprises a vector conversion module and a semantic identification module; performing vector conversion on the minimum semantic unit through a vector conversion module to obtain a one-dimensional vector group; fusing the vectors in the one-dimensional vector group, and inputting the fused vectors into a semantic recognition module to obtain a semantic vector, wherein the semantic vector is a first-level label identification result; obtaining a second-level label list from the semantic vector, and respectively inputting the second-lev
