I have a set of clusters which each cluster contains a list of short documents. I want to compute how coherent and cohesive each cluster is and filter out the incoherent and in-cohesive ones.
I am aware of intra-cluster distance and within-cluster dispersion, which are part of computing clustering evaluation metrics Silhouette Coefficient and Calinski-Harabaz Index, respectively. My question is, is there any other metrics or ways to compute such intra-cluster coherence or cohesion? Is there any standard ways for this that I am not aware of? Thanks.
