12 This serves as a crude form of word sense disambiguation (Wilks and Stevenson, 1998): for example, it would distinguish the different usages of "love" in "I love this movie" (indicating sentiment orientation) versus "This is a love story" (neutral with respect to sentiment).
the effect of this information seems to be a wash: as depicted in line (5) of Figure 3, the accuracy improves slightly for Naive Bayes but declines for SVMs, and the performance of MaxEnt is unchanged.
