Document Type and Number:
WIPO Patent Application WO/2022/048174
Kind Code:
A1
Abstract:
A text matching method and apparatus, a computer device, and a storage medium, relating to the technical field of artificial intelligence, the method comprising: constructing a question feature word set QU and a text feature word set QC, and a term set T; performing vectorisation processing to obtain a feature vector QE and a term vector TE; perform linear transformation to obtain a key matrix K, a query matrix Q and a value matrix V, and a matrix KT; calculating a non-normalised weight matrix AQT, and then performing self-multiplication and normalisation processing to obtain a plurality of sub-matrices; performing averaging processing on the plurality of sub-matrices, and then performing normalisation processing to obtain an impact matrix AQT
avg; performing matrix multiplication on the key matrix K and the query matrix Q to obtain a self-attention matrix A; calculating the output of a self-attention module, and then performing matching on the basis of the output. The present method focuses on matching between known terms, reducing the matching not between terms, and achieving the effect of increasing matching accuracy.
