基于概念格的知识获取

Knowledge Acquisition Based On the Concept Lattice

概念是人类进行知识表达的一种手段。数据库知识发现的过程就是将数据库中蕴含的知识形式化为有用概念的过程。而概念格正是从数据中进行概念发现的有力工具,用来发现数据中隐藏的知识模式。基于概念格理论提出了一种从形式背景中获得所有形式概念的算法,并根据构建的概念格提取蕴含规则。

Concept is a kind of means that mankind carries on the knowledge expression.Knowledge discovery process in database is to formalize the knowledge contained in the database into a useful concept.Concept lattice is a powerful tool for concept discovery from data,used to extract hidden knowledge pattern in data.The paper gives an algorithm of obtaining all form concepts from the formal context based on the concept lattice theory.And then,to extract the implication rules from the lattice.
