主动设计知识服务系统中的用户建模研究

主动设计知识服务系统的设计目标渡江是主动为设计者提供准确及时的设计知识服务，从而提高设计效率，用户模型的性能直接影响到整个服务系统的适应性，响应速度和服务的正确率，为了充分利用设计用户行为的纵向和横向关联，本文将模板和机器学习相结合的方法用于设计用户建模，提出了基于模板的用户建模过程模型，对基于机器学习的模型动态更新方法中关键技术以及用户模型的校验和反馈进行了讨论。

User Modeling in Active Design Knowledge Service Systems

Active design knowledge service system is aimed to provide accurate and just-in-time design knowledge services and thus improve the efficiency of design processes. The performance of user models plays a key role in the adaptivity, responsiveness and accuracy of these services. To make full use of historical and inter-user correlations, the stereotype approach and the machine learning approach are integrated to model design users. A stereotype-based user modeling process is presented. The key issues in the ML-based dynamic user model update are investigated. The verification and validation of user models are discussed.
