Narrative event prediction method fusing event environment information

Abstract

The invention belongs to the technical field of artificial intelligence, and particularly relates to a narrative event prediction method fusing event environment information. The method includes the steps that firstly, environment description directly related to a narrative event is obtained through the internal relation between the narrative event and a non-structural text; secondly, local and global event environment characteristics are extracted from environment description by utilizing semantic information of events through a multi-head attention mechanism; thirdly, mutual coding is performed on the narrative event characteristics and the environment characteristics through an event prediction model coding module to obtain event evolution characteristics of a fusion event environment; and finally, a narrative event prediction decoding module selects a correct next narrative event from the candidate items according to the evolution characteristics, and an event prediction task is completed. According to the method, the problem of insufficient utilization of event environment information in a narrative event prediction task can be solved, the event environment information can provide more perfect context information for a narrative event, and the understanding level of an event prediction model for event evolution is improved.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence, and specifically relates to natural language processing, in particular to an event prediction method for text data, and a narrative event prediction method integrating event environment information. Background technique [0002] As we enter the era of big data, more and more information is stored on the Internet in the form of unstructured texts. These texts, especially news texts, describe a large number of events that occurred in the real world. Such events recorded in a narrative tone are called Narrative events. The event chain composed of a series of narrative events includes each event in the event chain and its evolution relationship. Modeling narrative event chains can help artificial intelligence systems understand more complex and diverse real-world events. Good modeling of event evolution can promote many downstream applications, such as event-based knowledge graph co...
