Want to achieve few things
1. Normalize input data of clustering and classification algorithm
Not sure what you consider as normalization, but:
If u r trying to normalize text, Lucene's analyzers do it while generating term
vectors.
If u r trying to normalize the term vectors for clustering, the distance
measure specified while clustering normalizes the values appropriately based on
the chosen distance measure.
2. Normalize output data to plot in graph
The output from clustering is already normalized based on the specified
distanceMeasure (all of the clustered points r).
