A note on Umigon: best of its class

A comparative study has found that out of 24 solutions, Umigon is the best performer 🏁 for sentiment analysis on social media text in English. See the table below and check the paper behind Umigon:

Umigon ranks first

Note: “3-Classes” at the top of the left column means that the 24 solutions are judged on their performance on analyzing sentiments in three categories: positive, neutral and negative. “2-Classes” means that the solutions are tested on texts which are only positive or negative in sentiment. Umigon was released in 2012 and has been continuously updated and improved since.
