NAMED ENTITY RECOGNITION METHOD AND APPARATUS, TERMINAL DEVICE AND STORAGE MEDIUM

摘要

A named entity recognition method and apparatus, a terminal device and a storage medium, which are applicable to the technical field of computers. Said method comprises: acquiring text to be recognized, and converting said text into a n×k-dimensional first matrix (S301); performing convolution of multiple convolution layers on the first matrix, wherein a convolution operation is performed four times on the last convolution layer, of which the number of channels of the convolution kernel is m, so as to obtain four parallel n×m-dimensional second matrices (S302); performing attention weight adaptation on three second matrices of the four second matrices to obtain an n×m-dimensional third matrix, and performing matrix addition on the third matrix and the remaining second matrix to output an n×m-dimensional fourth matrix (S303); classifying the fourth matrix, and outputting an entity label corresponding to said text; and according to the entity label, outputting a named entity corresponding to said text. By introducing an attention mechanism in the convolution layer, the data redundancy is effectively reduced, and the recognition speed of named entities is increased.
