Thesis Details
Non-Supervised Sentiment Analysis
The goal of this thesis is to present an overview of the current state of research in the non-supervised sentiment analysis and identify potential research paths. Besides, the thesis introduces a novel self-supervised pre-training objective. Extending the model trained with the introduced objective with one extra layer of neural network and training it alone shows promising results. The extended model indicates an ability to encode the abstract representation of overall sentiment, emotions and sarcasm. A custom dataset was specifically collected for the pre-training objective introduced in this thesis. Future improvements and possible research paths are proposed based on the experiments performed with the extended model.
