EmotionGIF-Yankee: A Sentiment Classifier with Robust Model Based Ensemble Methods
This work addresses sentiment classification for social media data, but it is incremental as it builds on existing ensemble methods.
The paper tackled sentiment classification by using robust model-based ensemble methods and preprocessing tweet data, achieving third place among 26 teams in the SocialNLP 2020 EmotionGIF competition.
This paper provides a method to classify sentiment with robust model based ensemble methods. We preprocess tweet data to enhance coverage of tokenizer. To reduce domain bias, we first train tweet dataset for pre-trained language model. Besides, each classifier has its strengths and weakness, we leverage different types of models with ensemble methods: average and power weighted sum. From the experiments, we show that our approach has achieved positive effect for sentiment classification. Our system reached third place among 26 teams from the evaluation in SocialNLP 2020 EmotionGIF competition.
