基于本体的产品色彩意象知识表达

目的针对产品意象认知研究中色彩要素的重要性,基于本体论并结合感性工学的技术方法,构建了产品色彩意象本体,实现色彩意象知识的表达。方法通过对产品色彩意象本体概念的解析,使用语意差异法和KJ法挖掘用户的色彩感性需求,完成产品色彩意象概念的提取;应用混合聚类算法探索各色彩意象之间的层次关系,依据色度学原理分析产品的色彩特征,并获取设计要素及其类目;结合用户色彩意象感性评价值,运用数量化I类计算各色彩意象与设计要素、类目间的关联。结果根据研究结果构建产品色彩意象本体模型,用以高效指导产品色彩意象设计。结论以三厢轿车的色彩意象研究为例展开研究,可较好地实现汽车色彩意象知识的提取、表达与重用,为汽车色彩设计的知识获取开拓新思路。

Knowledge Expression of Product Color Image Based on Ontology

Focusing on the importance of color elements in product image cognition research, the product color image ontology is constructed to realize the expression of color image knowledge by applying the technical methods of ontology and kansei engineering. First of all, the method of Semantic Differential and KJ method are used to mine the user''s color sensitivity needs by analyzing the concept product color image ontology. Then, the hybrid clustering algorithm is applied to explore the hierarchical relationship between the various color images, and the color characteristics of the product containing the design elements and categories are analyzed according to the principle of colorimetry. Finally, combined with the user''s color image sensitivity evaluation value, the Quantification-I theory is taken to calculate the association between various color images and design elements and categories. According to the above research results, the product color image ontology model is constructed to effectively guide the product color image design. The sedan is carried out as an example to obtain the color image knowledge of cars, which may open up new ideas for the knowledge acquisition for automotive color design open up new ideas for the acquisi-tion of knowledge in automobile color design.
