16. The system of claim 15 , further comprising means for training a Naïve Bayes model based at least in part on the normalized document representation.
15. A system that facilitates and effectuates normalization of document representation, comprising: means for summing absolute term weight values associated with a document to determine a norm associated with the document; means for determining a term weight for a feature associated with the document; means for producing a normalized document representation based at least in part on dividing the term weight for the feature associated with the document with the norm associated with the document, and means for optimizing non-negative term weights under a rank preserving constraint comprising: means for acquiring a term weight.
