11. A method for use with tokens corresponding to terms within a document, comprising: evaluating each token against at least 2 different Markov models to determine respective relative probabilities that the token corresponds to the Markov models; for each token, comparing the relative probabilities with each other to determine which Markov model is more likely to be associated with the token; and identifying tokens most likely to correspond to a particular one of the Markov models, so that terms of interest within the document are identified.
