Natural language understanding priorities and one of the difficulties in the application of artificial intelligence techniques used in the field of mechanical design . In this paper, to achieve the abstract concrete modeling system based on the field of natural language understanding , and used in mechanical product design process . Intelligent analysis of user requirements expressed in natural language form , abstraction of good communication between the system and the user , and provide support for the subsequent design . In this paper, through the analysis of existing knowledge that the advantages and disadvantages of the method and design characteristics of the natural language representation based on the field of natural language understanding abstract knowledge of the specific modeling system , and build the field of abstract specific modeling system knowledge base. On this basis , the combined result of semantic analysis and discourse analysis , based on the relationship between the resource model concept and concept of operation , the field of abstractions Get abstractions specific interfaces born into the overall framework the field of abstract modeling specific methods . Abstract concepts concrete and then combined with the above work , field problems . Finally, the field of abstract concepts concrete modeling system for mechanical product design , user needs analysis process , combined with the rest of the modules of the system running , through a system test .
