Sentimetnal

No, it's not a typo 😁. According to Google Translate this is the Esperanto word for 'sentimental'.

Sentimetnal is a very simple sentiment analyzer based on Finn Årup Nielsen's AFINN word list.

It is basically a Ruby port of https://gist.github.com/fnielsen/4183541/ It returns a float for the sentiment strength of an input text.

Positive values are for a positive valence, negative values for a negative valence.

Add this line to your application's Gemfile:

gem 'sentimetnal'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sentimetnal

require 'sentimetnal'

analyzer = Sentimetnal::Analyzer.new
sentiment = analyzer.sentiment("The best & most delicious beef and friendly staff!" # 1.7677669529663687

sentiment.to_rating # 4

sentinment.to_emoji # :smile:

I'd like to try translating the word list and prepare it for the use with other languages...

1. Fork it ( https://github.com/[my-github-username]/sentimetnal/fork )
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create a new Pull Request

Unfortunately Ruby does not provide something like NLTK. But there are some interesting gems and code. I'm compiling my favorite ones here
