摘要: We present the IUCL system, based on supervised learning, for shared task stance detection. Our official submission, random forest model, reaches a score of 63.60, and is ranked 6th out 19 teams. also use gradient boosting decision trees SVM merge all classifiers into an ensemble method. analysis shows that good at retrieving minority classes majority classes. The strengths different wrt. precision recall complement each other in ensemble.
