Using emoticons can give results with an error percentage of around... 99.99% :) and the result maybe just 0.01% right. Coz, as kwamenum86 said, these icons are used to express personal feelings about an incident or news. My aunt might be in the ICU and when such a news is heard I give a sad emoticon. And that can't be counted when you want to decide if the world will be happy(not the whole world cares about my aunt). And at the same time I might be happy when a guy in my class scored less than me. He would be sad and I would be happy when we express this in emotes. (I'm not this bad). So if these emotes are to be really considered to count for the world's future happiness measure, then the text along with the emote also has to be parsed using Natural Language Processing to determine if its just a feeling about an incident or news that matters personally or the other way. I might be wrong too.
