Figure 1
Classifier ROC curves for the Spanish datasets.
The ROC curves illustrate the performance for classifying tweets as related to (positive) or not related to (negative) a given health state. Results shown are for a Naïve Bayes classifier trained with the subsets of features generated by four different feature selection algorithms. A) Depression, B) Pregnancy, C) Flu and D) Eating Disorders.
