On the Information Fusion of Multi-Source Formal Contexts

The knowledge discovery of multi-source data is one of the most important topics in big data analysis. This paper is devoted to the discussion of the information fusion of multi-source formal contexts. Based on residuated lattice theory, we present a method to combine multi-source formal contexts into an L -fuzzy formal context. The relationships among fuzzy concepts of the combined fuzzy formal context and classical formal concepts of single-source formal contexts are investigated. It is shown that the related fuzzy concepts and classical formal concepts can be induced from each other.
