为更好地从互联网获取适用的知识,以激发创新灵感,提出了一种面向产品创新设计的广义专家群体知识获取的思路及方法。首先对普通专家提供的知识样本进行分析,并提取样本特征。然后,针对产品创新设计知识的特点,构建了融入感性语义词汇的领域本体。基于领域本体,对专家知识样本特征词汇进行了扩展。在此基础上,通过搜索和过滤,获得了来自互联网的特殊专家的知识文本。进而运用知识元抽取技术,构建了广义专家群体知识库。最后,通过实例说明了特殊专家知识获取及过滤的效果,以及广义专家群体知识库的构建形式及结果。
A method of knowledge acquisition from generalized experts in product creative design was explored to obtain the knowledge from the Internet and inspire the creative thinking. Firstly, knowledge samples provided by common experts were analyzed and the characteristics of the samples were extracted. Secondly, according to the features of product creative design, the domain ontology which was integrated with words of perceptual meaning was con- structed, and the knowledge sample's characteristic words were expanded on the base of the domain ontology. On the above basis, the knowledge samples of the special experts from the Internet were acquired by searching and filtering, so as to construct the knowledge base of generalized experts by using the technique of knowledge element extraction. Finally, the effects of acquisition and filtering the special expertise, the form and result of establishing the knowledge base of generalized experts were revealed by a concrete example.
