Abstract

Unlike to traditional method, the new hierarchy syntactic analysis method faced Chinese long sentence comprises: 1. applying special functions of some punctuations to divide the complex long sentence into sub-sentence sequences; 2. extracting grammar rule and corresponding probability distribution information from large-scale database to analyze sentence and eliminate ambiguity. Much experiences show this invention can reduce time consumption and improves the analysis right rate and the recall rate about 7%.

Description

technical field

[0001] The invention relates to the technical field of natural language processing, in particular to a method and device for syntactic analysis of hierarchical Chinese long sentences based on punctuation processing. Background technique

[0002] Syntactic Parsing is one of the key technologies in natural language processing research, and the results of syntactic parsing directly affect the understanding of natural language sentences. Natural language understanding is the basis of many language processing technologies such as machine translation, information extraction, information retrieval, and automatic corpus processing. Under current conditions, syntactic analysis still plays a pivotal role in language information processing systems. At the same time, the technology used in syntactic analysis can also be used to solve problems similar to syntactic analysis in the field of biological information recognition, such as RNA molecular structure detection. The...
