Web usage mining with evolutionary extraction of temporal fuzzy association rules

Stephen G. Matthews, Mario A. Gongora, Adrian A. Hopgood, Samad Ahmadi
2013 Knowledge-Based Systems  
A genetic algorithm (GA)-based solution is described that uses the flexible nature of the 2-tuple linguistic representation to discover rules that occur at the intersection of fuzzy set boundaries.  ...  However, there is a problem with traditional temporal fuzzy association rule mining algorithms.  ...  The result was two sets of temporal fuzzy association rules: one set containing the traditional fuzzy set representation, and the other containing the 2-tuple linguistic representation.  ...
