Cover Story: Sentiment analysis is an important task in natural language processing (NLP), enabling the extraction of opinions from user-generated content such as product reviews and social media posts. This paper presents a comparative performance study of modern sentiment classification methods, including artificial neural networks, transfer learning, and large language models, against traditional machine learning models on a large dataset of Greek product reviews from e-commerce websites. The results show that advanced models like GreekBERT and GPT-4 outperform traditional machine learning classifiers, confirming their superior effectiveness for Greek sentiment analysis. This work also provides valuable insights into the capabilities of advanced models for Greek sentiment classification. View this paper
