Abstract: This paper presents an XML-based knowledge representation (XKR) that consolidates conventional representations， such as production, frame, semanti c network, procedure and so on， and uniformed in XML as form description langu ag e. The XML can contain semantic itself and be enriched unlimitedly so that XK R i s able to represent knowledge of different contexts or types and then fuses diff erent knowledge. Hence distributed knowledge base(DKB) is realized on it.

摘要： 提出了一种基于XML的知识表示方法——XKR（XML-based Knowledge Representa tion）。XKR把产生式、框架、语义网络、过程表示法等多种传统的表示方法融合到一起， 用XML作为统一的形式描述语言。由于XML本身包含语义并能够无限扩充，因此XKR可以描述 不同背景不同类型的知识，实现知识融合。在此基础上，进一步构建出分布式知识库。
