LocalTermWeights

object LocalTermWeights extends Enumeration

termFrequency: use the number of times the term occurs in the document (x = freqi).
binary: use 1 if the term occurs in the document or 0 if it doesn't (x = χ(freqi)).
logarithmic: take the logarithm (base 10) of 1 + the number of times the term occurs in the document. (x = log(1 + freqi))
augmentedNormalizedTermFrequency: this formula adds to the binary frequency a "normalized" component expressing the frequency of a term relative to the highest frequency of terms observed in that document (x = 0.5 * (χ(freqi) + (freqi / maxk(freqk))) )
