Abstract

The invention discloses an event extraction method, electronic equipment and a storage device. The event extraction method comprises the steps: acquiring event parameters of an event text, wherein the event parameter comprises an event category related to the event text and a plurality of event attributes of the event category; in each round of extraction process, selecting an unselected event parameter as a current parameter, constructing a question text about inquiring the current parameter, and inputting the question text and the event text into an event extraction model to extract an event word corresponding to the current parameter in the event text, wherein the question text comprises event words extracted before the current round of extraction. According to the scheme, the event extraction accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to an event extraction method, electronic equipment, and a storage device. Background technique [0002] The development of Internet technology has brought modern society into an era of information explosion. However, no matter ordinary readers or professionals such as journalists, they cannot avoid the influence of information overload. Therefore, it is necessary to extract event words related to the event from the unstructured event text, so as to help quickly and clearly understand the main situation of the event, thereby greatly improving the efficiency of users in obtaining event information. [0003] At present, the existing event extraction technology still has inaccurate extraction, especially in the face of complex text such as overlapping event parameters, the existing technology often cannot accurately complete the event extraction task. In ...
