Abstract

The invention discloses an event subject recognition model optimization method, device and equipment and a medium, and the method comprises the steps: inputting a training text into an information extraction module, and extracting character information and event information in the training text; inputting the character information and the main body label of the training text into a main body identification module to obtain a main body identification result and main body identification loss; inputting the event information and the subject recognition result into an event and subject matching module to obtain a matching result, and calculating matching loss based on the matching result and an event subject matching label corresponding to the training text; inputting the event information into an event classification module to obtain an event classification result, and calculating classification loss based on the event classification result and the event type label; and optimizing the subject identification loss, the matching loss and the classification loss to optimize the event subject identification model. According to the method, the classification problem is simplified, so that the error probability of the model is reduced, and the accuracy of event classification and event subject identification of the model is improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to an event subject identification model optimization method, device, equipment and readable storage medium. Background technique [0002] In many current financial scenarios, it is necessary to analyze many financial events reported by the media to help investment decisions, and even build quantitative financial modeling indicators. Event recognition (Event Detective, ED) is to identify the event type in the text, and event subject identification is to identify the subject of the event in the text. The existing event subject recognition model recognizes the text and recognizes the event type and event subject at the same time. The complexity is relatively high. For example, when a subject corresponds to multiple events, it is easy to misidentify the event type. Contents of the invention [0003] The main purpose of the present invention is to provide an e...
