Zero-shot text classification and evaluation for Emotion Analysis

Zero-shot text classification for Emotion Analysis

This workflow shows how to use Symanto Brain for zero-shot text classification for the task of emotions classification.

Zero shot classification on the English Unified emotions dataset (Bostan and Klinger, 2018)This workflow shows how to use the Symanto Brain for zero shot text classification, in this case for the task of emotions classification.ReferencesLaura Ana Maria Bostan and Roman Klinger. 2018.

Zero-shot classification with Symanto BrainPlease note that the zero-shot task parameters (labels, language, etc.)and the authentication key must be introduced inside the Zero-shotcomponent. Specifically at the Authentication and Zero-shotcomponents, respectively. Evaluate the modelCompute a confusion matrix betweenreal and predicted class values andcalculate the related metrics.
