面向海量历史设计信息的设计理性获取方法

Acquisition method of design rational for large amounts of historical design information

为解决产品设计理性的获取问题,依托大数据技术和信息提取技术,提出一种从历史设计信息中获取设计理性知识的方法。引入设计基因的概念对意图驱动的设计理性模型进行了拓展,提出了携带设计基因的意图链模型,阐述了利用大数据技术、信息提取技术提取设计基因和设计意图链的方法,并对所提取的设计意图链进行检验和修复,构建了元数据集,根据设计基因和设计意图对意图链进行拼接得到设计理性知识,并通过实例验证了该设计理性获取方法的有效性。

To solve the acquisition problem of product Design Rational（DR）,an approach of acquiring DR from history design documents was proposed based on big data information technology and information extraction technology.The concept of design gene was introduced to expand Intention Drive Design Rational（IDDR）model,and Design Intention Chain（DIC）model with design gene was put forward.The method to extract design gene and DIC by using big data technology and information extraction technology was elaborated.The proposed DIC was inspected and repaired to construct the meta data set.According to design gene and design intention,DIC was stitched to obtained DR knowledge,and the effectiveness of proposed method was verified with examples.
