在多数据库研究中，实现语义互操作是解决不同数据库之间语义异构性的最重要问题。在本文中，我们提出了一个基本框架，用于在多数据库环境中数据项之间的语义关系层面上实现语义互操作性。我们提出了一个元数据库系统，它从不同的数据库中提取重要信息。元数据库系统使用意义的数学模型来动态地识别数据项之间的语义等价性、相似性和差异性。该模型的本质特征是数据项的具体含义是动态固定的，并且通过语义解释机制根据上下文明确识别。 © 1995 约翰威利父子公司。
In multidatabase research, the realization of semantic interoperability is the most important issue for resolving semantic heterogeneity between different databases. In this paper, we propose a fundamental framework for realizing semantic interoperability at the level of semantic relationships between data items in a multi database environment. We present a metadatabase system which extracts the significant information from different databases. The metadatabase system uses a mathematical model of meaning to dynamically recognize the semantic equivalence, similarity, and difference between data items. The essential feature of this model is that the specific meaning of a data item is dynamically fixed and unambiguously recognized according to the context by semantic interpretation mechanisms. © 1995 John Wiley & Sons, Inc.
