为了在供需网环境下实现企业知识的协同管理,提出了供需网企业知识本体(SDNKO)的概念,根据SDNKO的多粒度特性,将SDNKO的概念空间划分为元概念层、领域模型层和应用实例层。在分析元概念类的层次结构和概念类的关联集后,针对电梯行业领域的企业知识本体概念空间进行了详细的说明。为表达供需网的协同知识语义,阐述了SDNKO概念框架的巴科斯范式和文档类型定义。最后,给出了供需网企业产品订单生成的知识协同管理实例。
In order to realize the enterprise knowledge collaboration management in SDN,this paper proposed the concept of SDN knowledge ontology(SDNKO).According to multi-granularity characteristics of SDNKO,divided the concept space of SDNKO into meta-concept layer,domain model layer and application instance layer.After analyzing on hierarchy structure of meta-concept class and association set of concept class,specified the concept space of SDNKO in elevator industry domain.Discussed the BNF for conceptual framework and document type definition of SDNKO for expressing the collaborative knowledge semantics of SDN.Finally,gave an example of product order generation for SDN knowledge collaboration management.
