Abstract
Recently, the properties of complex fuzzy concept lattice given a way to represent the uncertainty and its fluctuation. It given a well established mathematical model for understanding the dark data sets with respect to phase of time. The complex graphical structure visualization given a way to discover some of the useful pattern for decision making process. The problem arises when large number of complex fuzzy concepts are generated from the given context. To resolve this issue, a method is proposed for generating the complex fuzzy concepts based on maximal acceptance of complex fuzzy attributes (or objects) at given period of time. The information content is measured on Shannon entropy for the given phase of time. Thereafter, the complex fuzzy concepts are reduced based on their computed weight at different granulation to control the information pollution with an illustrative example. The obtained results are compared with recently available approaches on complex fuzzy concept lattice.
