  • Generative event extraction method based on ontology guidance
    Patent number: 12222970
    Abstract: The present invention is a generative event extraction method based on ontology guidance, including: (1) constructing an event ontology knowledge base; (2) designing an event trigger word extraction template and an event argument extraction template; mapping an input event text to a first input sequence, and mapping an input event text integrating an event ontology to a second input sequence; (3) designing a class label mapping function that maps multi-word labels to event types and/or role types; (4) extracting the event ontology corresponding to the input event from the event ontology knowledge base, and constructing the first input sequence and the second input sequence according to the event trigger word extraction template and the event argument extraction template; and (5) predicting, by the event extraction model, the event type and the role type according to the class label mapping function and a processing mechanism thereof, and outputting an event trigger word span and an event argument span.
