Embodiment Construction

[0022] A semantic analysis method based on a dependency tree of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] A semantic analysis method based on dependency tree, based on word segmentation, part-of-speech tagging, and dependency processing, and based on Chinese syntax, grammar, and semantics, it performs semantic analysis on text information in different professional fields, and extracts associations in text information .

[0024] Based on text segmentation, part-of-speech tagging and dependency processing, it provides a unified analysis process for text information mining in different professional fields.

[0025] Based on Chinese syntax, grammar, and semantics, through the seamless correspondence between Chinese and English, English semantic analysis is effectively applied to Chinese semantic analysis and reformed to improve the accuracy of semantic analysis.

[0026] Drawing lessons from English semantic an...

Abstract

The invention provides a semantic analysis method based on a dependency tree. Based on participle, part-of-speech tagging and dependency relationship treatment, Chinese syntax, grammar and semantics are used as standards for carrying out semantic analysis on text information of different professional fields, and the incidence relation in the text information is extracted. The method can serve as a universal tool, and semantic analysis can be carried out on target information only by constructing corresponding professional word banks, feature word banks and the like.

Description

technical field [0001] The invention relates to a semantic analysis method in natural language processing, in particular to a semantic analysis method based on a dependency tree. Background technique [0002] There is a large amount of data information in natural language. Through semantic analysis tools, it aims to mine the inherent associations contained in natural language. According to different data samples and research objectives, combined with the existing internal laws of Chinese grammar, semantics / pragmatics, using the syntactic dependency tree to construct the dependency relationship between different sentence components in the text, natural language processing, especially semantic analysis, It has always been the difficulty of text mining. The semantic analysis of English texts has achieved certain research results, but there is no ideal tool for the extensive and profound Chinese semantic analysis. [0003] As a method in artificial intelligence and computation...
