摘 要: 针对现代企业门户个性化、智能化的需求,将语义Web技术、上下文感知技术与门户技术结合起来,设计了一个可用于建立智能门户系统的上下文感知的模型视图控制器(MVC)框架CA-MVC。通过分析MVC模式的特点,定义了时序上下文本体,并详细阐述了上下文服务器中上下文获取模块、上下文推理模块以及上下文服务模块的功能。最后,结合在工作流门户系统中的应用,满足了通过门户为用户提供智能服务的需求。 In order to satisfy the personalization and intelligent support requirements for modern corporation's portal development, semantic Web, context-aware computing and portal technologies are combined together in designing a model-view-controller (MVC) framework which is based on context-aware computing,the CA-MVC. It can be used to construct the intelligent portal system. By analysing the characters of the MVC pattern, the sequential context ontology is defined, and the main functions of context acquisition, context inference and context service modules in context server are expounded. At last, by integrating its application in workflow portal system, the CA-MVC could meet the requirements of the intelligent services for users via the portal.
