This workflow uses a Kaggle Dataset including 14K customer tweets towards six US airlines (https://www.kaggle.com/crowdflower/twitter-airline-sentiment). Contributors annotated the valence of the tweets as positive, negative or neutral. Once users are satisfied with the model evaluation, they should export (1) the Vector Space and (2) the Trained Model for deployment over non-annotated data. If you use this workflow, please cite: F.
