An implementation of the Prior-Polarity baseline sentiment classifier described by Wilson et. al. For each word that may be associated to sentiment in english, use the prior (manually ascribed) sentiment to ascribe some form of sentiment to a phrase. This model is loaded from tff files using TFF. The default model is found in: /org/openimaj/text/sentiment/mpqa/subjclueslen1polar.tff
