基于OWL本体的关系数据库语义映射方法的研究

网络环境下不同关系数据库之间普遍存在着语义冲突，为实现系统互访，需要进行语义映射．针对目前关系数据库语义映射方法的不足，提出基于0WL本体的关系数据库语义映射方法，定义了从关系数据库到OWL本体的映射规则，描述了本体环境下语义冲突的检测算法，并针对几种常见的语义冲突给出了相应的解决方法．将关系数据库转换成OWL本体后，增强了关系数据库之间语义互操作的能力，实现了语义层次上的信息共享和交换，可以较好地解决关系数据库的语义映射问题．

Study on Semantic Mapping Approach of RDBs Based on OWL Ontology

Semantic conflict commonly exists in different RDBs in network environment.It needs to implement semantic mapping to facilitate interoperability.Taking into consideration of the deficiency of current semantic mapping methods about RDBs,an approach based on OWL ontology is presented.First,mapping rules from RDB to OWL ontology are defined.Next,detection algorithm for semantic conflict is described.Finally,corresponding solution methods are given related to some well-known semantic conflicts.The capability fo...
