Abstract:The design quality information and matching method based on semantic distance was presented in product designing process. Product design process was divided into five phases, and then the model of product design quality information was built. According to the model, the design task, designer and design quality information were analyzed. The task meta, object meta and information meta were described and the data structure was built. Using hierarchical network of concepts (HNC) and combining with semantic distance calculation, the quantification and comparing of text similarity can be realized based on framework of context text similarity. Finally, the conceptual design of injection molding machine was taken as an example, the result showed the effectiveness of the proposed method.
