Problems solved by technology

[0004] Although the existing sentence analysis methods reflect the grammatical structure of the sentence to a certain extent, there is no method to analyze the components in the sentence from the perspective of analyzing events, and there are the following deficiencies: (1) Analysis by grammatical function centered, not fully applicable to sentence analysis in Chinese (Chinese is a semantic language); (2) centering on verbs cannot cover all events in the sentence (such as: event nouns "earthquake", "fire", etc.); (3 ) lacks a description of the semantic function of modifiers, prepositions, conjunctions, and other components

Abstract

The invention discloses an event-structure-based Chinese statement analysis method, which is used for expressing a Chinese statement into a tree structure consisting of a plurality of event designators and event characters comprising event character uncorrelated components corresponding to the event designators. The method comprises the following analysis steps of first preprocessing the Chinese statement; then performing event-structure-based Chinese statement analysis, finding the event designators in the statement and the event characters corresponding to the event designators, and analyzing multi-character components and the event character uncorrelated components; and finally labeling each statement component, adding function descriptions of each component, and giving a parenthesis representation form of a tree representation structure. The method is more applied to Chinese syntactic analysis, relationships between event elements are reflected, support is provided for semantic synthesis, and a language representation method and representation rules of an event can be reflected. According to the method, the event designators which are not verbs can be processed, and semantic functions of modifiers, prepositions, conjunctions and other components can be described.

Description

technical field [0001] The invention relates to a Chinese sentence analysis method based on an event structure, which belongs to the field of natural language processing (Natural Language Processing). Background technique [0002] There are a large number of descriptions of various events in human life (as small as an action, as large as a historical event) in natural language, and also include the time, place, participating roles, status, and relationship between events, etc. with a description of the characteristics. The Chinese sentence analysis method based on the event structure of the present invention is to analyze and map each component in the sentence from the perspective of understanding the event structure, and express it in a formalized way. Different languages ​​have different representation methods and representation rules. People can know and understand the world by recognizing events and the relationship between events. This is also one of the important co...
