dc.description.abstractThis study enhances Aspect Sentiment Triplet Extraction (ASTE) by integrating Large Language Models (LLMs) and a semantic Backus-Naur Form (BNF) framework to analyze expert reviews on electric vehicles. A 2-tuple fuzzy linguistic model improves sentiment representation, ensuring interpretability. Applied to YouTube reviews of top-selling EVs, the method effectively structures technical and qualitative data for decision support.es
