Abstract: This paper proposes an extensible mapping rule model to make up for the deficiency of conflict resolution only by mapping to global ontology in ontology-based XML data integration systems. Based on this model, a conflict resolution algorithm is given to solve the problem of incorrect result from interoperations among local data sources, such as joint operation and unification of query results from heterogeneous data sources.

摘要： 针对目前基于本体的XML数据集成系统中，仅仅通过映射到全局模式来进行冲突消解的不足，该文提出了一种可扩展的映射规则模型。基于该模型，给出了一个冲突消解算法，可以较好地解决由于局部数据源间的冲突引起的局部数据源查询结果整合不正确和数据源间的连接操作失败等局部数据源互操作中出现的问题。
