基于用户兴趣特征的知识推送

摘要

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.%为弥补产品设计过程中知识检索方式的不足，同时降低因需求不明确导致知识推送的盲目性，提出了一种根据用户兴趣特征进行筛选实现设计知识推送的方法。首先阐述了基于用户兴趣特征的产品设计知识推送原理，给出了设计知识组织管理方法。然后分析了用户兴趣特征集合的构建方法，采用文本相似度算法，实现了知识特征与兴趣特征的匹配。最后以某电气产品制造企业为背景，通过应用实例验证了该方法的可行性和可靠性。
