中文摘要：
通过引入交式可约元概念,文中提出了一种形式背景属性约简的新方法.基于此方法,获得了形式背景属性约简个数计算的精确公式,改进了原有的约简个数估计.在此基础上,给出了概念格的生成算法及其图示.最后,针对协调决策形式背景,通过实例给出了新的属性约简方法.
英文摘要：
By the concept of intersectional reducible elements,a new algorithm for attribute reduction of formal contexts is proposed.The formula to calculate the number of attribute reduction of formal contexts is obtained based on the reduction method,which improves the result for estimating the number of attribute reduction.On this basis,an algorithm to generate concept lattices and its corresponding graph is designed.Finally,a new method for the attribute reduction of consistent decision formal contexts is presented via an example.
