一种使能虚拟组织的本体动态构建机制

Dynamic Ontologies Construction Mechanism for Enabling Virtual Organizations

如何应对虚拟组织成员本体的变更问题是构建虚拟组织本体面临的主要挑战。该文提出一个半自动的本体构建机制DODO,通过动态捕获并吸收成员本体更新的领域知识来实现虚拟组织本体的不断演化完善。该机制还可辅助领域专家消除虚拟组织本体变更所产生的影响。实际应用表明,使用DODO机制能够保证虚拟组织本体对变更成员本体领域知识的平均覆盖程度始终维持在一个较高的水平。

A challenging problem of constructing Virtual Organization（VO） ontology is how to deal with the problem of member ontologies variations. This paper proposes a semi-automatic mechanism called Dynamically cOnstruct Domain-specific Ontology（DODO）, with which VO ontology can be evolved and consummated by continuously capturing and absorbing updated domain knowledge of VO members. This mechanism also can facilitate domain experts to eliminate the impacts of changing VO ontology. The practical application shows that the DODO mechanism can provide a high average degree of covering member ontologies domain knowledge for VO ontology.
