Pretraining and Fine-Tuning Strategies for Sentiment Analysis of Latvian Tweets
This work addresses sentiment analysis for Latvian language users, but it is incremental as it builds on existing methods for a specific domain.
The paper tackled sentiment analysis on Latvian tweets by exploring pretraining and fine-tuning strategies, achieving 76% accuracy, which is a substantial improvement over previous work.
In this paper, we present various pre-training strategies that aid in im-proving the accuracy of the sentiment classification task. We, at first, pre-trainlanguage representation models using these strategies and then fine-tune them onthe downstream task. Experimental results on a time-balanced tweet evaluation setshow the improvement over the previous technique. We achieve 76% accuracy forsentiment analysis on Latvian tweets, which is a substantial improvement over pre-vious work
