Text-based event detection method and apparatus, computer device, and storage medium

Abstract

A training method includes obtaining a first data set and a second data set, each of the first data set and the second data set including event instances, the event instances include text and events corresponding to the text. The training method also includes training an adversarial network using the first data set and the second data set, the adversarial network includes processing circuitry configured as a generator and a discriminator. The discriminator is configured to output first reliable probabilities of the event instances in the first data set, and second reliable probabilities of the event instances inputted by the generator. A loss function of the adversarial network is used to adjust a parameter of the adversarial network, to maximize the first reliable probabilities and minimize the second reliable probabilities. The method further includes obtaining, by the trained adversarial network, a reliable event instance in the second data set.
