Research And Implementation Of Automatic Modeling Method In Product Design

This paper designed and realized automatic modeling system and applied it in theelectronical product design process. Based on the Domain Chinese LaguageUnderstanding System, it accomplished the transition from the user's requirementexpressed by natural language to the designing requirement of the Concept Design ordesignparameter,tosupplythesustainfornextdesign.First, some current methods and theories of NLU knowledge expression and thecharacteristicofnaturallanguagueindesigndomainarepresentedand compared,thenaway to express NLU discourse information is given and applied to the construction ofNLU Discourse Knowledge Base. Based on the Knowledge Base, combined the resultsof semantic analysis and discourse analysis and the connection between concepts ofresource model , the method of automatic modeling is given which includs confirmingthe domain ,digging and orgnaizing information of the problem ,reducing informationand building interface. Based on the work done, the processing flowchart of the wholesystemisgiven,whichcanfinishtheautomaticmodelingofdomainpromblem.Finally , the automatic modeling system is applied to anlyse and understand theuser's needs ofthe digital filterdesign.
