Problems solved by technology

[0004] In addition, most of the existing technologies use unsupervised clustering methods or graph-based probability methods to extract Chinese events and study evolutionary events. Since it is difficult for existing technologies to accurately capture the connection between Chinese events, the existing technologies Most of the evolutionary events obtained from the study of Chinese events have low correlation, so the prediction process of evolutionary events is meaningless, and the accuracy of evolutionary events is not high

Abstract

The invention relates to an event evolution knowledge graph construction method, device and equipment, and a storage medium. The method comprises the steps of obtaining a Chinese news report of news;extracting corresponding event elements from the Chinese news report, and combining the event elements into a Chinese event corresponding to the Chinese news report, the event elements comprising event trigger words and event arguments; based on event arguments in the event elements, aiming at each piece of different news, associating a plurality of different Chinese events corresponding to each piece of different news; and according to the priori cause relationship of the event trigger words, constructing an event evolution knowledge graph among a plurality of associated different Chinese events. According to the method, the problem of low accuracy of the evolution event in the prior art can be relieved, and the technical effect of improving the accuracy of the evolution event is achieved.

Description

technical field [0001] The present application relates to the technical field of natural language processing, and in particular to a method, device, device and storage medium for building an event evolution knowledge graph. Background technique [0002] Events are a specific form of information, and event extraction is an important research direction in natural language processing. The task of identifying the occurrence of events and extracting the elements of events from free text has become a difficult research point in text information extraction and mining. ACE2005 (Automatic Content Extraction 2005) defines this task as: identifying specific types of events, and determining and extracting related information. A specific type of event is found in the specified source language data, and the information related to the event is identified and filled into the prior event template. [0003] At present, most of the research on event extraction is carried out on the ACE Engli...
