【摘要】 大多数应用系统是采用“选择／执行”的模式来响应用户的。这种工作方式只能简单地响应用户的命令而不能给用户以灵活的指导。本文提出了一种新的智能用户界面的修正Petri网模型。这种用户界面模型能够提供主动的服务以取代被动的“选择／执行”服务方式。在修正Petri网模型中严格区分描述界面系统行为的功能子网和表示相关知识及进行推理的子网。知识子网采用特定的调用／返回流关系进行通讯。更多还原

【Abstract】 This paper presents a new modified Petri net model of active user interface that is based on knowledge representation and reasoning. This model can provide active services to avoid the passive select-execution mode in the most of applications that always makes most user interface systems can only respond to users’ orders simply and can not afford instructions to users flexibly. This modified Petri net model can strictly distinguish between function subnets manifesting interface system behaviors and knowledge subnets representing relevant knowledge and performing inferences. Moreover, some special call-return stream relationships are produced, which are communication channels among two kinds of subnets in the modified Petri net model.更多还原
