一种基于概念格的集值信息系统中的知识获取方法
A knowledge acquisition method based on concept lattice in set-valued information systems
摘要
Abstract
The paper takes set⁃valued information systems as research background, proposes a knowledge acquisition method on the basis of concept lattice. The model can transforms a complicated set⁃valued information system into a simpler one⁃valued context, and then by means of concept lattice, emphasizes the granularity model based on toler⁃ance relation and the algebra structure in the set⁃valued information system, where the algebraic structure can or⁃ganize all covers in the form of lattice structure, and it can be considered an important algebraic structure in the set⁃valued information system. Meanwhile, the paper also offers some simple solutions to common problems, such as re⁃duction, core. In short, this paper not only helps to explore the application range of concept lattice, but also offers a useful idea for the analysis and processing of set⁃valued information systems.关键词
