Emoji Support

[thisandagain]

The AFINN wordlist is missing a fairly critical piece of contemporary discourse: the emoji. I'd like to add emoji support to sentiment. Major questions:

• Do any approaches to evaluating the sentiment of emoji exist?
• How do we tokenize emoji?
• Should this be an "opt-in" feature?
• How do we determine the accuracy of such an implementation?

Hi

Are the emojis part of the default wordlist or would these need to be added in?
I tried to manually append via code as i don't want to edit the wordlist directly using the following but it doesn't seem to take into account the smiley face ":)"

var analysis = sentiment(post.message, {
                            ':)': 5,
                            ':(': -3,
                            'xxx': 3,
                        });

The 'xxx' works correctly though so at first i thought it maybe because the word starts with punctuation and may be getting ignored?

Thanks any help would be greatly appreciated

Thanks
