摘要
随着MIS的广泛应用,数据的存储和表示呈现出各种各样的异构性。传统的异构数据共享方法不能对数据的形式化语义进行描述,难以解决异构信息源中的语义异构。"本体"是共享概念模型的明确的形式化规范说明,作为通用语义模型来描述异构数据语义具有较强的概念表达能力和推理的能力。文中利用元数据对分散、异构数据进行明确的规范,给出了一种基于本体的异构数据共享方法。实验表明,该方法能较好地解决异构数据的语义异构问题,为用户提供具有一定语义功能的信息共享。
With the extensive application of MIS,data storage and representation showing a variety of heterogeneous nature.The traditional method of heterogeneous data sharing can not describe the formal semantics of data,it is difficult to resolve the semantics of heterogeneous information sources heterogeneous.＂Ontology＂ is a shared conceptual model of a clear formal specification,as a general semantic model to describe the heterogeneous data semantics of the concept has strong expressive power and reasoning capabilities.In this paper,meta-data for distributed,heterogeneous data gives a clear normative ontology-based heterogeneous data sharing methods.Experiments show that the method can better solve the heterogeneous problem of heterogeneous data semantics to provide users with certain semantic features of information sharing.
