【摘要】 自动地、按需集成Webservices要求解决高层次目标规划问题和任务分解,要求集成是在概念层次上进行的。通过引进带覆盖声明的、单调性的继承机制,建立了一种新的过程本体论模型。过程继承蕴含了任务的分层递解关系,使得过程本体论可表示面向用户的问题解决方案。在该基础上提出了一种在知识层级上自动集成Web服务的框架。更多还原

【Abstract】 To realize the automatic and on-demand integration of Web services,it is necessary to resolve such issues as the high-level task decomposing and the goal planning at the concept level.The paper proposes a process ontology model by adopting an inheritance mechanism with overriding declaration and monotonic inheritance.The inherited relation among processes implies a layered structure of task decomposing.A framework of automatic composition of Web services at knowledge level is proposed.更多还原
