针对电子商务自动化、智能化和移动化的新趋势,应用本体论对电子商务知识建模,提出电子商务知识描述的分层框架,结合描述逻辑、框架系统设计了基于XML和本体论技术的电子商务知识描述语言(KDL)。介绍了KDL的语法,从一阶逻辑的角度分析KDL的语义特征,提供KDL描述到一阶逻辑表达式的映射方法。最后,通过实例证明KDL具有规范的语法、精确的语义和较强的逻辑推理能力。
Abstract
According to the increasingly intelligent and mobile characteristic of E-commerce , an XML-based and ontology-supported E-commerce Knowledge Description Language (KDL) is first presented , which has three-tier structure (Core KDL , Extended KDL and Complex KDL) , and takes advantages of strongpoint of ontology , XML , description logics , frame-based systems. And then , we introduce the XML-Based syntax of KDL , and give the methods of translating KDL into first order logic. At last , the reasoning ability of KDL proved by experiment is illustrated in detail.
