Text Mining and Clustering

Cindy Mcmullen-OracleDec 17 2015 — edited Dec 22 2015

Hi -

I'm using Oracle 12c and SQL*Developer 4.1.1.  When using K-Means clustering on text, in combination with themes, I assume feature extraction is a pre-processing step.  Is this correct?  If so, which algorithm is used for feature extraction:  PCA or NMF, or ...something else?

Thanks -

-- Cindy
