Abstract: Clustering is an important area in data analysis in which we try to find natural groupings of objects based on their similarity (or alternatively, dissimilarity). In many studies, information on dissimilarity are basically qualitative. In such situations an order invariant approach to cluster analysis is desirable. Furthermore, in areas of study such as biological taxonomy or cognitive science, we often look for hierarchical clustering of objects where object groupings can be examined at different levels of refinement. Traditionally order invariant approaches to hierarchical clustering are based on some form of graph connectivity, or measures such as cluster diameter and separation. In this paper, we propose a new approach to order invariant hierarchical clustering based on an ordinal consistency perspective that is suitable for qualitative or subjective dissimilarity data. We show some experimental results that demonstrate the advantages of our method.
