This Builder Method implementation generates category term weights as a vector per category that exists in the same vector space as the document term vector. The similarity between the document vector and each of the category vectors can then be calculated using euclidean distance or cosine similarity (angle). Alternatively, these weights can be used for a linear regression formula, calculating a score rather than a similarity/distance.
A combination of global term weights (across the corpus), local term weights (within each category) and normalization (per category) is used to calculate these category vectors.
