语义Web服务框架比较及本体异构协调

Semantic Web Service Framework Comparison and Ontology Heterogeneity Coordination

文章对语义Web服务框架OWL-S与WSMO的结构特点和适用范围进行比较分析。OWL-S的目标是实现机器的可理解性和易用性,WSMO研究语义Web服务语言的标准,它由本体、目标、Web服务和中介器组成。WSMO缺乏对具体操作进行形式化建模,仅适用于自己的语言WSML。OWL-S是Web的本体语言,支持RDF和OWL等语言,语义Web环境下适用性强。针对两种框架结构下本体的异构冲突问题,给出了OWL-S表示WSMO中Mediator的本体-本体中介器、目标-目标中介器和服务-服务中介器的方案。通过网络教学平台的应用,验证了解决方案的有效性。

Structural characteristics and application scope of OWL-S and WSMO which are frameworks of semantic web services are studied.The goal of OWL-S is to realize the intelligibility and easy use of machine.WSMO,which is consist of ontology,goal,web service and mediator,relates to semantic web service language standard.WSMO only supports WSML of its own and is insufficient in formal modeling of practical operation.OWL-S is ontology language and supports RDF and OWL,etc.thus having general availability in semantic environment.In view of the collision of ontology heterogeneity in these two frameworks,a plan about how to express oo-mediator,gg-mediator and ww-mediator of WSMO mediator with OWL-S is put forward.The effectiveness of the plan is proved in the application of e-Learning platform based on semantic web.
