Title:
LONG TEXT EVENT EXTRACTION METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/035330
Kind Code:
A1
Abstract:
Disclosed in the present application are a long text event extraction method and apparatus, and a computer device and a storage medium. The method comprises: acquiring a trigger word in long text of an event to be extracted, and performing text truncation on the long text according to the trigger word, so as to obtain truncated text; using a deep learning model to classify and predict a plurality of event types corresponding to the truncated text; in combination with machine reading comprehension technology and a pointer network model, extracting corresponding event role information for each event type; and on the basis of a sequence generation algorithm, combining all event role information into a target event, and outputting the target event as an event extraction result. In the present application, by means of performing event classification, event role extraction and event combination on long text, the event extraction efficiency and extraction accuracy of the long text are improved.
