摘要
为了减少语义异构性带来的信息发现、集成和存取的困难,论述了语义元数据构造,提出了通过集成现存的本体和主题词表构造元数据模式的一种新方法,即元数据模式构造的两步方法:在主题词T和本体O之间的连接关系规范;概念主题词表的自动构造。这个集成基于主题词术语和本体概念之间的蕴含关系规范,并产生具体应用的元数据模式,同时也给出利用结果元数据模式构造RDF模式的过程。
In order to reduce the difficulties in information discovery,integration and access by heterogeneous semantics,present a new approach for building metadata schemas by integrating existing ontologies and structured vocabularies (thesauri).This integration is based on the specification of inclusion relationships between thesaurus terms and ontology concepts and results in application-specific metadata schemas.Also show how the result of this integration can be used for RDF schema creation.
