Overview of Event Extraction
Given input text, an event extraction model will first identify an event and then classify that event into a particular schema. From there, the model will identify arguments related to the event and then classify the roles of those arguments
Event extraction can be broken down into four subtasks:
- Trigger identification
- Trigger classification
- Argument identification
- Argument Role Classification
