classified provides an abstract interface to common ruby classifiers. It allows comparison of these classifiers using common corpora to compare accuracy, precision, recall and f-measure metrics.
gem install classified
bundle install
NOTE: You will need to have installed the libarchive library to support the decompression of the corpora used in the comparisons.
bundle exec rake metrics:all
