摘要
规则获取是当前形式概念分析领域的研究热点.首先给出了基于对象导出三支概念格间的细于关系,定义了基于对象导出三支概念格的三支弱协调性,并研究了其与经典概念格下的二支弱协调性之间的关系.然后,研究了基于对象导出三支概念格的规则获取,并与经典概念格的规则获取进行了比较.最后,定义了对象导出三支概念的弱闭标记,研究了基于弱闭标记的三支弱协调决策形式背景的规则获取,剔除了冗余规则,并且得到一些新的更为精简的三支规则.
Rule acquisition is the research focuses in the field of formal concept analysis.Firstly,the finer relation based on object-induced three-way concept lattice is given,the three-way weakly coordination is defined.And the relationship with the two-way weakly coordination of classical concept lattice is studied.Then,the rules acquisition on objectinduced three-way concept lattice are presented,and compared with the classical concept lattice.Finally,the weakly closed label of object-induced three-way concept is defined.And the rules acquisition of three-way weakly consistent formal decision context based on the weakly closed label are investigated,which can remove the redundant rules and get some new and more streamlined three-way rules.
