The formal concept analysis is based on mathematical concepts and conceptual level, it has stimulated people think of the conceptual data analysis and knowledge processing data method. The formal concept analysis is a branch of the application of lattice theory, this article first two chapters overview of the concept lattice dynamic and defined the background of single-valued and multi-valued context concept lattice. On the Interval multi-value background, defines the range of algorithms; on the language multi-valued context the defined the linguistic scale, that is, the standard language multi-context.The third chapter in the multi-valued background processing, introduces the concept of scaling principle, several basic ruler; comparative analysis, and laid the foundation for the flexible use of multi-valued background into the concept of scaling and logical scaling.In the chapter different types of multi-valued background mainly discusses how the background of language-type multi-valued, interval multi-value context converted to numerical multi-valued background.Chapter four focuses on language-based multi-valued context, interval multi-value background converted to numerical multi-valued background,highlights the interval multi-valued background into the process of transformation, the innovation is introduced the concept of distance range, the introduction of the close function. In the third quarter, for a clearer understanding of the background of multi-valued implicit information, to give you a simplified method based on attribute importance attributes. In the fourth part function depends on the context of multi-valued is the same as the attributes contain in the single-valued context, Section V introduced the multi-valued attribute equivalence class, through constraint the attribute simplified concept lattice processing.Chapter5focuses on the visualization of the concept lattice.Chapter6describes the application of the concept lattice, and how decisions are made.
