Problems solved by technology

[0003] However, in the process of corpus processing using word segmentation technology, after word segmentation, there will be multiple parts of speech in the composition of the regular expression, and the regular expression corresponding to the obtained user corpus matches multiple regular expressions. It is still impossible to accurately judge the semantics and entities. Therefore, it is necessary to analyze the user corpus through a semantic understanding method and system to obtain the most likely corresponding user semantics

Abstract

The invention provides a semantic understanding method and system, and the method comprises the steps: obtaining a corpus sample, and building a corpus according to the corpus sample; obtaining feature information according to the corpus sample, and generating a corresponding regular expression according to the feature information; respectively extracting feature information in the regular expressions to generate a plurality of different regular expression combinations; analyzing the existence accuracy of each piece of feature information in each regular formula combination, and screening theregular formula combinations; analyzing a regular expression probability corresponding to the regular expression according to a corpus, wherein the regular expression is a combination of the regular expression and the screened regular expression; Generating a probability semantic model according to the regular expression and the probability of the regular expression; Obtaining a user corpus; Generating a corresponding user regular expression according to the user corpus; And comparing the user regular expression with the probability semantic model to obtain user semantics of the user corpus. According to the method, the acquired user corpus is analyzed based on the probabilistic semantic model, so that the most possible user semantics is obtained.

Description

technical field [0001] The invention relates to the technical field of language processing, in particular to a semantic understanding method and system. Background technique [0002] With the rapid development of the network, intelligent processing of information is becoming more and more common. Computers, smart devices, etc. may need to process thousands of information every day. Smart devices generally analyze the corpus to obtain the corresponding regular expressions, thereby parsing the corpus. [0003] However, in the process of corpus processing using word segmentation technology, after word segmentation, there will be multiple parts of speech in the composition of the regular expression, and the regular expression corresponding to the obtained user corpus matches multiple regular expressions. It is still impossible to accurately judge the semantics and entities. Therefore, it is necessary to analyze the user corpus through a semantic understanding method and system...
