面向产品创新设计的网络知识获取及挖掘

Product innovation design-oriented network knowledge acquisition and mining

针对创新设计过程中的知识获取和挖掘需求,建立产品创新设计知识库的结构,拓展知识获取的广度和深度,并提出采用向量空间模型的夹角余弦算法对知识进行挖掘处理。实验表明,所提出的网络创新知识的获取和挖掘算法是有效的,可协助设计人员实现创新知识的自动筛选,显著提高了知识利用效率。

Aiming at the designers＇ needs of knowledge acquisition and mining in product innovation design process,an innovation design knowledge base is established,the breadth and depth of network knowledge resource are also expended,then,using angle cosine algorithm mines the required knowledge.Finally,the experiment result show that the proposed network knowledge acquisition and mining is effective,which can help designer select innovation knowledge automatically and significantly improve the knowledge utilization efficiency.
