This workflow applies an RNN, trained on the Kaggle Dataset (https://www.kaggle.com/crowdflower/twitter-airline-sentiment), on new tweets around #xxx to predict their sentiment. The last component visualizes (1) the bar chart with the number of negative/positive/neutral tweets, (2) the word cloud of all collected tweets, and (3) the table with all collected tweets. This workflow is tailored for Windows. If you run it on another system, you may have to adapt the environment of the Conda Environment Propagation node. If you use this workflow, please cite: F.
