The document describes an industrialized sentiment analysis system called JuLiA that was developed to help automate comment moderation at the Huffington Post. JuLiA uses machine learning algorithms like SVM, naive Bayes, and AdaBoost trained on a gold standard dataset of moderator-labeled comments. It supports preprocessing, parallelized model training, and ensembling of top models. Initial results found naive Bayes to be the best single model, while ensembling and logistic regression on multiple model outputs improved performance. Further steps include expanding the training data and developing per-vertical models.
