摘要
概念格作为一种研究概念内涵与外延的有效工具,在规则提取与数据分析方面有着广泛的应用。讨论了概念格的构造、约简与规则提取,以及模糊概念格的相关内容,并对各种建格算法、约简算法加以论述,分析其与粗糙集的关系,最后提出了未来概念格的相关研究方向。
Concept lattice is an effective tool for dealing with the relationships between extent and intent of concept,which is also widely applied to rule extraction and data analysis.The construction of concept lattice was discussed,as well as reduction and rule extraction,and fuzzy concept lattice.The constructing and reduction algorithm were also proposed and its relation with rough set was analyzed.Finally,the research of improved development of concept lattice is prospected.
