摘要
为了解决存在逻辑联系的知识要素之间的冲突消解问题,定义了知识元的统一语义表达方式,将知识元之间的冲突按照粒度分为术语冲突、谓词冲突和语义冲突;提出了消解术语冲突的逻辑树融合法,消除谓词冲突的频率融合法以及用于消除语义冲突的句法融合法.实例证明,3种冲突消解算法能对存在冲突的知识元进行冲突消解.
This paper aims at investigating the semantic level knowledge fusion methods in distributed resources, and solving the conflicts resolution problems between logically connected knowledge elements. A uniform representation of meta knowledge was defined; conflicts were categorized into three types according to granularity which are terminology conflict, syntax conflict and semantic conflict. Logic tree method was proposed to resolve terminology conflict; frequency fusion method was applied to resolve syntax conflict and syntax fusion method to resolve semantic conflict. Those methods were demonstrated in the knowledge of aeronautics and astronautics field to realize the knowledge fusion.
