摘要： 基于本体的语义信息集成主要解决分布异构的数据源之间的模式级异构和部分数据异构(包括同义字和同音异义字)。在基于本体的语义信息集成的基础上引入上下文机制来全面解决异构数据源之间的语义异构，弥补了基于模式映射的语义信息集成的不足，具有较好的适应性和扩展性。

Abstract: Ontology-based semantic information integration resolves the schema level heterogeneity and part of data level heterogeneity between distributed data sources. Ontology-based semantic information integration can’t resolve this context heterogeneity. In this paper, a context mediation based information integration frame is put forward to resolve the attribe-level context heterogeneity, hence the complete resolution of semantic heterogeneity is formed and the resolution is adaptive and extensive.

Key words: semantic information integration, schema semantics, attribe-level context heterogeneity, context mediation
