title:
Divergence-from-randomness model
text:
The divergence from randomness is based on this idea: "The more the divergence of the within-document term-frequency from its frequency within the collection, the more the information carried by the word t in document d. In other words, the term-weight is inversely related to the probability of term-frequency within the document d obtained by a model M of randomness."(By terrier.org) weight = k Prob M
- M represents the type of model of randomness which employs to calculate the probability.
