A composition model of enterprise information system based on domain ontology

Through analyzing the architecture and domain commonness of enterprise information system (EIS), the paper proposes a composition model of EIS based on domain ontology. The paper specially gives the formal description of EIS domain ontology, and proposes the composition algorithm based on semantic similarity of concepts in domain ontology. At last this paper gives an example which uses the composition model. The practice proves that this model can enhance the efficiency of software development, and can reduce the development costs.
