Semantic Based Virtual Organization Model

摘要

Virtual organization has emerged as important research field. But less attention is paid to the semantic based model of virtual organizations, virtual organizations creation and evolution are still difficult This paper combines semantic web technology with architecture based modeling approach to semantically describe virtual organizations and yield semantic based virtual organization model. Component specification is attached with semantic information and component relationships are semantically defined. The semantic based virtual organization model supports semantic match between business requirements and semantic Grid services. The semantic of relationships and entities are defined rigorously, a primary benefit is that they facilitate automated reasoning. Patterns are used to describe business component composition and service component composition, and support virtual organization integration at varying levels of granularity. Patterns map business goal into Grid services so that virtual organization evolution is supported effectively.
