The Research Of Domain NLU Discourse Model And Its Application In Mechanical Manufacturing Process Design

The application of NLU technology in mechanical manufacturing process design is one of the most important and difficulty application of A.I. technology. This text tries to ues Chinese natural language discourse understanding technology to comprehend the intelligence analysis of the mechanical manufacturing process design, realize the good exchange between the system and customers, provide the support for the following design, expecting to improve the current situation that the intelligence degree of computer assistance mechanical design is not high.This text analyzes the typical problems of the natural language discourse understanding, analyzes and compares the advantages and disadvantages that a few existing knowledge representations have, establishes the discourse connotation knowledgebase with the"association"character, based on the concept model theory. Otherwise, it puts forward the center theory based on the analysis and comparation of the existing discourse parsing theories and methods, establishes the righteousness block division model,discourse connation parsing model and discourse integrity analysis model based on the center theory, and carry out the concret processing methods aiming at the event and processing type of discourse. Finally, it is applied in the mechanical manufacruring process design domain with actual condition, and its result turns to be satisfied.
