摘　　要：遗留系统 ( Legacy系统 )通常依赖不同概念结构 ,由于语义层的冲突 ,难以实现互操作 .通过重建语义层对 Legacy系统进行概念化封装 ,并通过语义转换规则 ,解决遗留系统之间的语义互操作问题 .The conflicting structures (ontologies) hinder the interoperability among legacy systems. This paper introduced a strategy to reconstruct a semantic view over a legacy system and build a wrapper based on the mapping between this semantic view and the data view. Through this process the legacy system is open to other systems. The semantic mapping among the ontologies of legacy systems was also discussed. The proposed strategy is a feasible approach to implement the reuse and integration of legacy systems.
