Semantic equivalence judgment method and device

Abstract

The invention discloses a semantic equivalence judgment method and device. The method comprises the steps of generating a plurality of vectors corresponding to a first statement and a plurality of vectors corresponding to a second statement according to the first statement and the second statement; matching the plurality of vectors corresponding to the first statement with the plurality of vectorscorresponding to the second statement, and generating similarity representation according to a matching result; splicing the similarity representations, and screening the spliced similarity representations through a similarity representation layer of the model; inputting the screening result into a self-attention layer of the model, calculating a self-attention value through the self-attention layer, wherein the self-attention value reflects the internal structures of the first statement and the second statement; and judging whether semantics between the first statement and the second statement are equivalent or not according to the self-attention value. The method is higher in accuracy for judging whether semantics among multiple sentences are equivalent or not compared with the prior art, so that the method can be used for solving the problems in the prior art.

Description

technical field [0001] The present application relates to the technical field of machine learning, in particular to a method and device for judging semantic equivalence. Background technique [0002] With the continuous advancement of artificial intelligence-related technologies, question-answering robots have also received more and more attention. In order to better improve the question-answering effect of the question-answering robot, it needs to have a deep understanding of the semantics of the sentence, and one of the keys is to judge whether the semantics of multiple sentences are equivalent. However, in the prior art, the accuracy of judging whether the semantic equivalence between multiple sentences is low is low, so a more accurate semantic equivalence judging method is needed. Contents of the invention [0003] Embodiments of the present application provide a method and device for judging semantic equivalence, which can be used to solve the problem of low accurac...
