多级分布式语义Web服务自动组合

Multilevel Distributed Automatic Composition Semantic Web Services

基于用语义Web服务自动组合解决复杂任务,本文作者提出了一种形式化的多级分布式语义Web服务自动组合框架MUDICS(MUltilevelDIstributedautomaticCompositionsemanticwebServices)。在系统接收到一个服务请求后,中心Agent(HA)首先用HTN规划器完成第一阶段的规划,将复杂问题划分成一组与领域紧密相关的子任务,然后将这些子任务发送给相应的带有UDDI注册中心的子Agent(SAWU)进行第二阶段规划。本文通过扩展OWL S建立Web服务本体OWL S4SAWU(OWL SforSAWU),并用其来描述SAWU的功能,然后将SAWU的功能描述注册到HA作为HTN规划的资源。

A complex task will be solved by using automatic composing semantic web services. This paper provides a formal, multilevel distributed semantic web service composition framework MUDICS. After receiving a request, HA complete the first stage planning using the HTN planer, which will divide a complex problem into some subtask related to special domain, and then send the subtask to correct SAWU for the second time plans. In particular, the author develops a simple OWL-based Web service ontology, which is the same as OWL-S, to describe the capabilities of SAWU, and register it to HA.
