摘要
分析数据集成中的语义异构问题和已有数据集成方法,提出一种基于混合本体和Mediator/Wrapper的语义数据集成模型,将数据元素作为领域数据概念标准引入到全局本体的构建中,并给出全局本体自动构建算法.设计并实现模型原型系统,系统运行结果证明,该模型能够有效地解决数据集成的语义异构问题,并可为各个领域的语义数据集成提供参考.
By researching on the semantics heterogeneous of data integration and data integration methods,we propose a semantic data integration model based on the mixed ontology and mediator/wrapper.Data element has been introduced into the construction of global ontology as the concept of domain data and automatic construction algorithm for the global ontology has been proposed.We design and implement a prototype system for this model.Operation of the system proved that this model can someway solve the problems of semantic heterogeneous in data integration domain,and it can also provide a reference for semantic data integration in various fields.
