Zero-shot text classification and evaluation for Sentiment Analysis in German

Zero-shot text classification for Sentiment Analysis in German

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


Zero shot classification on the German SB10k sentiment dataset (Cieliebaketal., 2017)This workflow shows how to use the Symanto Brain for zero shot text classification, in this case for the task of sentiment classification.ReferencesMark Cieliebak, Jan Milan Deriu, Dominic Egger, and Fatih Uzdilli. 2017. A Twitter corpus and benchmark resources for German sentiment analysis. In Proceedingsof the International Workshop on Natural Language Processing for Social Media, pages 45–51.

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-shot component. Specifically at the Authentication and Zero-shotcomponents, respectively. Evaluate the modelCompute a confusion matrix betweenreal and predicted class values andcalculate the related metrics.
