摘要
装备信息集成中存在着大量的语义异构数据源,阻碍了信息的共享和交换。本体可以描述信息之间隐含的关系,在语义和知识层次上描述信息系统的概念模型,有效地解决信息集成中的语义异构问题。通过对基于本体的信息集成方法的分析,采用Wrapper/Mediator架构,提出了基于混合本体的装备基础信息集成框架,给出了框架的层次结构和关键技术。结合实际对基于本体的装备指标体系构建和查询处理问题进行了研究,验证了基于本体的信息集成方法在装备领域信息集成中的可行性和有效性。
Large numbers of semantically heterogeneous datasources exist in information integration of the equipment.It baffles the share and exchange of infromation.Because the ontology can be used to describe the hidden relations between information and describe the concept model of information system on semantic and knowledge.So it can effectively solve the semantic heterogeneity in information integration.On the analysis of ontology-based information integration,puts forward an equipment basic information integration framework based on hybrid ontology,which adopts Wrapper/Mediator structure.Then level and key technique of the framework are given.The construction of equipment Index Architecture and the problem of query processing based on ontology are researched.The feasibility and effectiveness of the information integration method on the basis of ontology are verified in the equipment information integration.
