Due to lack of appropriate standards and norms, and different awareness in the field of digital mine among academia and industry insiders, the meaning for digital mine is still unclear. Starting from the nature of mining and removing of views of specialized fields, this paper constructs formal ontology for digital mine and proposes the four levels for it. The ontology clarifies the concept world for digital mine, defines the meaning of concepts and relations clearly, provides a reference for the standard construction for digital mine and provides a unified semantic framework for the integration of heterogeneous mine data. Meanwhile, it can provide formal reasoning knowledge for expert system of digital mine and improve the intelligence and automation while the machine automatically interpreting and processing mine spatial data.展开更多

文摘针对家电企业产品生命周期管理中产品设计存在着手工建档、查询困难和协同性差的状况,将本体理论引入家电领域。在研究家电领域顶层本体构建方法和本体语义扩展方法的基础上,提出功能语义扩展方法 isa,构建功能本体;采用OWL(Ontology Web Language)语言对家电产品设计知识进行表达,构建以用户需求为导向的索引知识库;采用映射方法和相关度匹配方法对用户需求与本体知识索引进行转换,实现语义共享。最后以文中索引知识模型构建某家电企业设计知识共享平台,表明该模型是可行的。
