Juxtaposition Processing Faced To Chapter In NLU And Its Application In The Mechanical Design Domain

This paper sums up and sorts processing for juxtaposition structure in Chinese, and applies semantic analysis of juxtaposition structure into the machine transmission design. Through understanding and analysis to user requirement in the form of nature language, transforms analysis results into demand of conception design, in order to provide help for after design.This paper simply introduces research instances and characteristics about NLU in machine design domain. Through analyzing difficulties of Chinese semantic analysis and comparing several actual semantic analysis methods, we adapt conceptual dependency theory as the based theory. The emphases of this paper is the research of familiar juxtaposition structure, through analyzing of juxtaposition phrase from syntactic and semantic,bring forward the understanding model suitable for the verb of juxtaposition phrase. Base on the model, combine the semantic analysis of verb, we give detailed resolve means of the juxtaposition verb phrase and write semantic analysis program, realize the semantic analysis in domain. For the understanding of the juxtaposition clauses, we discuss and solve them faced to chapter effectively, realize the NLU of the juxtaposition clauses.Finally, this paper applies semantic analysis of the juxtaposition verb phrase into the domain of user demand analysis about machine product design. Through system testing, the result is satisfactory comparatively.
