Problems solved by technology

[0003] At present, event extraction in traditional technologies is based on template matching and machine learning. However, event extraction in related technologies is only for sentence-level texts. For chapter-level texts, there may be a large number of escape symbols in the text and crawl Elements caused by irregularities are chaotic, and event elements may be distributed in different sentences, resulting in low accuracy in extracting elements related to financial events, thus affecting the overall performance of financial event extraction

Abstract

The invention discloses an event extraction method and device, equipment and a storage medium. The method comprises the steps of obtaining a to-be-processed text; inputting the to-be-processed text into an event detection model for detection processing, and determining an event type in the to-be-processed text; constructing a first inquiry corpus based on the event type; inputting the to-be-processed text and the first inquiry corpus into a reading understanding model, and determining event parts in the to-be-processed text; and based on the event type and the event part, determining an event extraction result of the to-be-processed text. According to the technical scheme, due to the fact that the event detection model and the reading understanding model are used, the event type and the event part in the to-be-processed text can be accurately determined, the method is suitable for event extraction in text-level texts, the overall performance of event extraction is improved, and the event extraction efficiency is further improved.

Description

technical field [0001] The present invention generally relates to the technical field of natural language processing, and specifically relates to an event extraction method, device, equipment and storage medium. Background technique [0002] With the continuous development of network information technology, the amount of online text information on the Internet has increased dramatically, especially in the process of digital explosion in the financial field. There are a large number of financial documents, such as a large number of company announcements and company annual reports, but these data Most of them are unstructured or semi-structured data, which require manual analysis to obtain structured data. In order to better make major decisions such as investment analysis and asset management in the financial field, it is necessary to process massive financial documents. Among them, event extraction is a key technology for processing large-scale financial document informatio...
