Problems solved by technology

However, the current research on the structural model of long sentences and the relationship between sentence patterns and ideographic patterns is still in its infancy, and before syntactic analysis, sentence patterns are usually unknown, which makes us need to consider other To start with, try to solve this problem

Embodiment Construction

[0070] The specific steps of the hierarchical Chinese long sentence syntax analysis technology based on punctuation processing are as follows:

[0071] Step 1: Segment complex long sentences containing segmentation punctuation;

[0072] Step 2: Perform first-level syntactic analysis independently for each clause unit;

[0073] Step 3: Detect and merge phrases in parallel relation;

[0074] Step 4: Carry out the second-level analysis on the basis of the first-level analysis results, and finally obtain the complete syntax analysis tree of the entire sentence.

[0075] Figure 1: The overall structure diagram of the entire system device, which consists of four parts: a long sentence segmentation device, a first-level analysis device, a detection and merging parallel phrase device, and a second-level analysis device. The above devices are connected in sequence.

[0076] Figure 2: Represents the conditions that a "split" punctuation definition satisfies. Among them, the punctuati...

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...
