Abstract: An event argument extraction (EAE) method, an EAE apparatus and an electronic device, relates to the technical field of knowledge graphs. A specific implementation scheme includes acquiring a to-be-extracted event content; and performing argument extraction on the to-be-extracted event content based on a trained EAE model, to obtain a target argument of the to-be-extracted event content; where the trained EAE model is obtained by training a pre-trained model with event news annotation data and a weight of each argument annotated in the event news annotation data.

Abstract: The present disclosure provides a method for generating an event theme, belonging to a field of knowledge graph technologies and a field of deep learning technologies. Pieces of event information in an associated relation are obtained. Entity information and an event type of each piece of event information are obtained. Target event information having representative attributes is obtained from the pieces of event information. A theme template matching the event type of the target event information is selected from a theme template collection. The entity information and the event type of the target event information are added into the theme template to generate a theme of the pieces of event information.
