摘要
概念格是知识处理与分析的一个有力的工具,在知识约简方面有着重要的利用。首先给出了概念格中不同类型属性的等价刻画定理,在此基础上得到了一种新颖的概念格属性约简算法,最后通过实例表明了该约简算法的可行性与有效性。
The concept lattice is useful in knowledge processing and analying.And it has been used with a high intensity to knowledge reduction.First,the theory of measuring the characteristic of diffenent attributes equivalently is given in this paper.And then a novel algorithm to find attribute reduction of concept lattices is proposed.Finally,a real example is used to demonstrate both its feasibility and effectiveness.
