Abstract

The present application relates to an event prediction method, device and terminal equipment based on event evolution knowledge ontology. Among them, the method includes: by constructing an event evolution ontology knowledge base with event evolution relationship, extracting the first event chain and the first event tuple from the event evolution ontology knowledge base, adopting remote supervision, using the first event element The group and the first event chain carry out relational data back-labeling on unstructured texts to obtain event data with event evolution relationship, and use event data training to establish an event prediction model, which can effectively and quickly obtain a large number of marked training based on knowledge. data, thereby effectively improving the accuracy of event prediction.

Description

technical field [0001] The present application relates to the technical field of computer information processing, and in particular, to an event prediction method, apparatus and terminal device based on event evolution knowledge ontology. Background technique [0002] With the frequent occurrence of emergencies in recent years, the whole society is paying more and more attention to emergencies. Without adequate preparation, emergencies are often caught off guard, and when life safety is involved, time is life. Therefore, only quick and accurate responses can escort life safety. The relevant experience accumulated in the handling of more and more emergencies can be used as a preparatory measure to deal with future emergencies, and the development of events can provide great help for the prediction of emergencies. [0003] After analyzing related technologies, the inventor realized that the event prediction method in related technologies relies on specific words to construct...
