摘要
提出对基于OWL-S描述的语义Web服务操作语义的Petri网描述新方法。选择动态描述逻辑的动作理论作为语义Web服务描述的逻辑基础,一个OWL-S原子进程可以作为一个动态描述逻辑动作进行描述,实现了对OWL-S原子进程的动态执行和相关执行条件静态逻辑推理的有机结合,进一步通过将Petri网与动态描述逻辑的动作理论结合,得到OWL-S进程(尤其复合进程)操作语义的Petri网描述,为组合语义Web服务的自动组合和动态性质分析提供了更为有效的逻辑依据和方法。
Putting forward a new approach to model OWL-S based semantic web services operational semantic with petri nets, selecting dynamic description logic actions theory as the logical foundation of semantic web services. Firstly, a OWL-S atomic process can be modeled as a dynamic description logic action, which combines the dynamic execution and static reasoning of related execution conditions of services; and then, using petri nets and dynamic description logic actions theory to model operational semantics of OWL-S services processes, especially composite processes, provides a more effective logical approach to study auto-composition and dynamic properties analysis of semantic web services.
