We provide prototype code of our paper "Saliency as Evidence: Event Detection with Trigger Saliency Attribution". The code structures are: 1) `sentence_label_predict_ace.py` contains code for training a sentence-level event classifier; 2) `salient_evluation.py` contains code for using the sentence-level classifier for trigger saliency attribution. 3) `event_detection_train_ace.py` contains code for grouping event types into different categories and training separate ED models. 4)`event_detection_train_ace.py` contains code for evaluation.
