Abstract

The invention relates to an event evolution knowledge ontology-based event prediction method and apparatus, and a terminal device. The method comprises the following steps: 1, , an event evolution ontology knowledge base with an event evolution relationship is constructed; extracting a first event chain and a first event tuple from an event evolution ontology knowledge base, remote supervision mode, utilizing the first event tuple and the first event chain to perform relational data remarking on the unstructured text; according to the method for establishing the event prediction model throughevent data training, a large amount of marked training data can be effectively and quickly obtained based on knowledge, and therefore the accuracy of event prediction is effectively improved.

Description

technical field [0001] The present application relates to the technical field of computer information processing, and in particular to an event prediction method, device and terminal equipment based on event evolution knowledge ontology. Background technique [0002] With the frequent occurrence of emergencies in recent years, the whole society pays more and more attention to emergencies. In the absence of adequate preparation, emergencies are often unprepared. If life safety is involved, time is life. Therefore, only by responding quickly and accurately can we guarantee the safety of life. The relevant experience accumulated in the handling of more and more emergencies can be used as preparatory measures to deal with future emergencies, and the development of events can provide great help for emergency prediction. [0003] After analyzing related technologies, the inventor realized that the event prediction method in related technologies relies on specific vocabulary to c...
