Hi all, I am trying to cluster a set of text documents using Apache Common math. The document might belong to multiple clusters, so i used the Fuzzy kmean clustering implementation. Things are working fine except that the final clusters do not contain overlapped documents. My understanding is that the final clusters should have documents that overlapped across documents. I tried setting different values for fuzziness parameters, but it did not work. The final clusters always contain non overlapping documents.
I have a class called "DocumentPoint" that extends the Clusterable interface, then i am using something like this: FuzzyKMeansClusterer<DocumentPoint> clusterer = new FuzzyKMeansClusterer<DocumentPoint>(k,fuzziness); clusterer.cluster(docPoints); return clusterer.getClusters(); Help is very much appreciated. Regards Ameer
