چکیده
Association rules are essential data mining tool and as such has been well researched. Many new types of association rules based on both categorial or quantitative data have been founded ([8], [7], [2], [4]). Our work is directed to the theoretical features of association rules; especially, we study a specific class of association rules called δ-cosymmetric rules. We present here some interesting properties of such rules and provide a definition of rules expressing the significant difference in position, as an example. We show here that even the usual implicational rules are special cases of δ-cosymmetric rules.
