Abstract: A new clustering validity index based on the improved classic method of representatives is presented.First of all,the clustering result is corresponding to the Kripke structure.The relevant system of axioms is chosen by the correspondence between the syntax and semantics of modal logic.Furthermore,a minimal data set which can describe all clustering information is constructed by the implication during formulas.Finally,the validity index is calculated based on the above set.In addition to the validity of a clustering result,this method can also show the structure information of each cluster.Experiments show that this new index has more universal than the current clustering validity indexes.
