An Interpretable Classification Framework for Information Extraction from Online Healthcare Forums Table 3 Model evaluation. We evaluate each model using 5-fold cross validation. Each of the average accuracy, weighted average precision, weighted average recall, and weighted average F-score for medication class, symptom class, and the overall performance is presented in each column. Each row represents the performance of each model trained on different feature combinations.
