We show that the sentiment of a negated expression (such as not w ) on the [-1,1] scale is on average 0.926 points less than the sentiment of the modied term w , if the w is positive. However, the sentiment of the negated expression is on average 0.791 points higher than w , if the w is negative.cues for inferring the sentiment polarity.
