Compound Sentences Semantic Analysis Of NLU Within Mechanical Products-designing Domains

This text applies nature language understanding semantic analysis to the mechanical product design, through understanding and analyzing to the user's needs that are expressed in the form of natural language, and transform analysis result into the designing requirement of the concept or design parameter, offer a good design environment to user and designer.First of all, carry on the contrast to the existing semantic analytical method , find out the pluses and minuses of each theory, especially, introduce the Case grammar and the conceptual dependency theory , synthesize but two advantages regard as theoretical foundation . then turn the movement concept of comprehensive semantics into corresponding event. At the same time, the semantic process of simple sentences, some complex sentences, events and nouns with event properties are studied in detail. then give the way to resolve the uniqueness problem to each semanteme concept while dealing with the compound sentence, and the utilizing again of event knowledge.At last, the semantic analysis is applied to the design of the Man-machine interface in machine clamps. Meanwhile, the knowledge database and some rules of semantic analysis of events are established and it runs well after debugging. It is hopeful to realize the computer-aided user requirement analysis.
