Enhancing Implicit Sentiment Recognition with LLMs
Client: E-commerce Review Platform
Challenge: Difficulty in identifying implicit sentiments (e.g., sarcasm, indirect opinions) in customer reviews, leading to inaccurate sentiment summaries.
Solution: Implemented a prompt-based LLM (Flan-T5) framework for single aspect sentiment classification, leveraging chain-of-thought reasoning to infer implied opinions.
Results: Improved F1-score for implicit sentiment by 15% and reduced manual annotation effort by 40%, leading to more nuanced product insights.
Methods for jointly modeling multiple interrelated sentiment elements, such as aspect-sentiment pairs or quadruples.
