Abstract: 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.

Key words: design information, design rational, design gene, big data, knowledge acquisition, product design
