Definition: Given a 'poster' sentence and a corresponding 'response' (often, from Facebook or Reddit)classify the sentiment of the given response into four categories: 1) Positive, 2) Negative, 3) Neutral, and 4) Mixed if it contains both positive and negative.
Input: Poster: My latest blog from COP20: Stephen Harper attacks his own climate promises on the very day his Environment Minister repeats them in Peru to the COP. Shameful. http://elizabethmaymp.ca/news/latest-news/2014/12/09/canadas-dismal-presence-2/  Responser: I guess if he says something enough his "base" will think it's true, classic neurolinguistic programming or NLP - lots of sociopaths and salesmen use this technique.
