Abstract:To offset the shortage of knowledge retrieval methods for product design process, while to reduce the blindness of knowledge push due to uncertain demand, a method according to users' interest feature to achieve knowledge push is proposed. Firstly the theory of design knowledge push based on users' interest feature is expounded, and the mothod of knowledge organization and management is given. Then the method for establishing user interest feature set is analyzed, and the match between knowledge feature and interest feature is realized by utilizing similarity matching algorithm. Finally case is given to illustrate feasibility and reliability of knowledge push method.
