面向服务的本体元建模理论与方法研究

Research on Service Oriented Ontology&Meta Modeling Theory and Methodology

为实现互联网上异种异构的复杂信息资源有序化组织和互操作性服务与共享的目标,文章研究了语义服务的元计算问题,提出了本体元建模理论和方法.首先定义了本体UML承诺、提倡本体UML表达,给出了本体的元机制;论述了元建模中的“元”概念,给出了元层次停止准则、模型转换机制;然后提出了本体建模和 MOF元模型设施相融合的体系结构,给出了以用户为中心的复杂信息资源服务应用模式 SCDI,为本体元建模方法的体系化提供了基础.还介绍了作者在国际 ISO SC32标准MMFI for Ontology Registry研究中的应用成果.最后给出了 HL7领域本体与元模型设计的应用.本体元建模为语义服务计算的实现,提供了一条可行的路径.

The meta computing problem in semantic service is investigated and the ontology & meta modeling theory and methodology are proposed in this paper for the purpose of ordering organization, interoperability service and sharing of heterogeneous complex information in internet. The UML commitment for ontology is defined and UML expression for ontology and ontology meta mechanism is proposed at first. The “meta” concept in meta modeling,the meta level termination criteria and model transformation mechanism are discussed secondly. At last the architecture combining ontology modeling and MOF is proposed, and the user centric complex information resource service application pattern——SCDI is presented. These form the fundamental systematic theory for the ontology & meta modeling. The application of ISO SC32 standard MMFI for Ontology Registry is also introduced, and the application of HL7 domain ontology and metamodel design is presented. The authors argue that ontology & meta modeling provides a feasible solution for the implementation of semantic service computing.
