英文摘要： Product innovative design is the most active and creative stage in the process of product design, is a combination superposition and transfer of existing knowledge or resources based to produce new products. Knowledge extraction of big data brings extraction brings new opportunities for product innovative design. Big data is introduced into the field of mechanical discipline in this project, knowledge extraction research of product innovative design is carried out in the environment of big data from the perspective of innovation design and multidisciplinary. For the Mapping between characteristics of big data and the knowledge of product innovative design, the supporting method of knowledge extracted from big data for concept generation of product innovative design is researched. With integrating subjective knowledge of designers and knowledge mined from big data, it builds the procedural model of knowledge evolution for big data and acquires different levels and abstracted granularity of knowledge to support the generation of product innovative concept. For the designers could not acquire interested design knowledge and knowledge clues related to searched content by conventional knowledge searching strategy, intelligent recommendation method of big data based on knowledge graph is researched. To support the effective implementation of the design process for the front-end of innovation, solving method of reducing the uncertainty for front-end innovation in strategy is researched. The research on knowledge extraction from big data for product innovation design will offer useful theoretical and methodological support for designers that carry out product innovative design.
