基于总线式集成框架的本体构建及映射研究

通过本体的构建及相应的本体映射策略,可以很好地解决信息集成过程中出现的语义异构问题。是实现异构数据源语义解析的基础。在已有研究成果总线式信息集成框架的基础上,针对目前本体构建过程存在的不足,提出了基于共享词汇表的全局本体构建技术和基于UML的局部本体构建技术,使所构建的本体元素间关系更加准确完备,具有良好的一致性。提出了基于综合相似度的本体映射策略,大大提高了本体映射的精度。

Research on Intology Building and Ontology Mapping Strategy Based on Bus Enterprise Information Integration Framework

Ontology building and mapping technology is mainly for the elimination of the semantic heterogeneity of heterogeneous data sources and is the foundation to realize the heterogeneous data semantic analytical.Based on the existing research results of bus framework for enterprise information integration and aiming at the existing problems of ontology building process,this paper puts forward global ontology building technology based on the sharing glossary and local ontology building technology based on UML,which makes the relationship of constructing ontology element become more accurate,complete and with good consistency.Also it simplifies the process of building ontology workload.And the ontology mapping strategies based on comprehensive similarity is proposed,the integrated similarity is calculated from four aspects:concept name,structure,property,instance,which greatly improves the ontology mapping precision.
