Subject Lucene. How to build a term-doc matrix
Date Fri, 21 Jan 2011 08:05:20 GMT

Hi all,
I need to build that matrix but I can't find a way to compute normalized
tf-idf for each cell. The normalization I would perform is
cosine-normalization that is divide tf-idf (computed using DefaultSimilarity
) per 1/sqrt(sumOfSquaredtf-idf in the column).

Does anyone know a way to perform that?
Thanks in advance
Antonio
