สรุป	Implicit sentiment analysis detects indirect, context-dependent sentiment in text where no explicit opinion word is present — such as irony, metaphor, or understated criticism. Unlike standard sentiment analysis, which relies on surface-level polarity signals, this method interprets meaning from surrounding context, pragmatic cues, and world knowledge. It is typically addressed using large language models or fine-tuned transformers, drawing on work by Tang et al. (2016) on deep-memory aspect-level classification and Zhao et al. (2023) on LLM-based sentiment reasoning.	Text classification, also called text categorization, is a supervised natural-language-processing task that automatically assigns documents to predefined categories. Building on the support-vector-machine approach to text categorization established by Joachims (1998) and consolidated in the text-mining literature by Aggarwal and Zhai (2012), it powers tasks such as spam detection and topic classification by learning from labelled examples.
