针对石油领域采油采气工程分布、异构的数据源,我们在构建领域全局语义模型和实现全局语义查询的基础上,建立了面向采油采气工程的基于领域本体的数据语义集成及服务系统PeSDS.系统通过对领域数据模型进行本体抽取、本体归并,建立适合各个油田的全局语义数据模型；通过本体映射、查询转换、数据清洗,实现领域数据的语义集成,为用户和上层应用程序提供基于语义的数据访问和共享服务.用户和上层应用程序通过全局语义数据模型,可以以即需即用的方式,直接访问底层的分布、异构数据源,PeSDS经过语义查询,将清洗过的数据以统一的格式返回.
For oil field oil gas recovery project of distributed,heterogeneous data sources,we are in the field of building global semantic model and implement global semantic query,on the basis of established oil gas recovery engineering oriented data semantic integration and service system based on domain ontology PeSDS.System based on the extraction of ontology,ontology merging domain data model,establish global semantic data model is suitable for various oilfield; Through ontology mapping,query transformation,data cleaning,realize the data in the field of semantic integration,for the user and the upper application based on semantic data access and Shared services.Users and upper application through global semantic data model,can,in the form of the need to use direct access to the underlying distributed,heterogeneous data sources,PeSDS through semantic query,data will be cleaned in a uniform format to return.
