Abstract

The invention discloses an event element identification method and device, and relates to the technical field of information extraction. According to the specific implementation scheme, the event element identification method comprises: obtaining candidate sentences from a target corpus according to a preset trigger word list, and the candidate sentences comprising trigger words in the preset trigger word list; determining event statements and event types of the event statements from the candidate statements through statement characteristics of the candidate statements by utilizing a rapid text classification model; and according to the event type of the event statement, identifying event elements in the event statement. According to the method, the statement characteristics of the candidate statements are obtained by utilizing the rapid text classification model, and the event statements can be rapidly and accurately screened out, so that event elements in the identified event statements can be more accurate.

Description

technical field [0001] This application relates to the field of computer technology, in particular to the field of information extraction technology. Background technique [0002] As an important part of portraying a corporate portrait, corporate public opinion covers information on personnel, capital, operations, and other related events in the production and operation activities of the enterprise. This information is of great significance for evaluating the potential risks of the enterprise. Corporate public opinion data is usually unstructured text data from various platforms, so it is necessary to identify and mine the required structured information from it. However, the current methods of event extraction and event element identification have certain defects, which lead to low recall and precision of the final event element identification, which cannot meet the requirements of accurately portraying corporate portraits.
