摘要： 为解决数据交换过程中的语义冲突问题，提出一种基于本体的语义冲突消解方案。利用ER模型实现关系模式到XML模式的语义映射，采用本体对经过初步语义转换的XML Schema进行语义标注。实验结果表明，该方案能减少由自然语言或符号不同引起的歧义，在一定程度上消除语义冲突。

Abstract: To resolve the semantic conflicts in the process of data exchange, an improved semantic conflict resolution scheme is presented. It uses ER model to realize the semantic mapping from relational schema to XML Schema, and uses ontology to make semantic annotations on XML Schema which is translated semantically and preliminary. Experimental results show that this scheme can reduce the ambiguity caused by the difference of natural language or symbol, semantic conflicts between the heterogeneous data sources are resolved to some extent.

Key words: data exchange, semantic heterogeneity, semantic conflict, conflict resolution, ontology, semantic annotation
