From: Wide coverage biomedical event extraction using multiple partially overlapping corpora
Restriction of negative instance generation. Different events annotated in the GE and EPI corpora are shown, along with the differences in training instances that would result in a simple merge (Merge) and our newly proposed method (Multiple) for trigger/entity and argument detectors, when all the triggers and entities are detected by the trigger/entity detectors. NONE shows negative instances, and spuriously created examples are shown in bold.
