Problems solved by technology

[0004] 1) For the method based on regular expressions: usually the flexibility is relatively poor when extracting slot values, and a few more or fewer words in the middle of the sentence will cause the expression matching to fail
[0005] 2) For the method based on the neural network model: the recognition in this method depends on the size of the training corpus, so the accuracy is usually not high
Especially in the development platform application, the statement templates input by users cannot be fully utilized, and the statement templates newly added by users cannot be updated in real time.

Abstract

The invention discloses a semantic recognition method and device, and relates to the technical field of computers. The method comprises the specific steps that to-be-recognized statement information is acquired; the to-be-recognized statement information and preset statement templates are matched based on the longest common subsequence, and a matching result with a weight value is determined; semantic recognition is carried out according to the matching result. The method can perform more accurate semantic recognition on the acquired to-be-recognized statements on the basis of the matching method with the weight value of the longest common subsequence according to the preset statement templates, completely utilize statement template information, and be higher in flexibility and high in efficiency. In addition, the method can update the statement templates in real time in a short time to perform subsequent testing feedback.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a semantic recognition method and device. Background technique [0002] Two key issues in natural language understanding technology are the identification of intent and the extraction of slot values. In the open platform service of natural language understanding, the intention will be identified and the slot value will be extracted according to the sentence template entered in advance. At present, there are two main methods for automatic extraction of slot values: the method based on regular expressions and the method based on neural network models. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1) For the method based on regular expressions: usually the flexibility is relatively poor when extracting slot values, and a few more or fewer words in the middle of the sentence ...
