Effective clustering of a similarity matrix

Question

my topic is similarity and clustering of (a bunch of) text(s). In a nutshell: I want to cluster collected texts together and they should appear in meaningful clusters at the end

Answer 1

Maybe you can transform your similarity matrix to a dissimilarity matrix such as transforming x to 1/x, then your problem is to cluster a dissimilarity matrix. I think the hierarchical cluster may work. These may help you:hierarchical clustering and Clustering a dissimilarity matrix
