Sentiment Analysis
A classic task in natural language processing that identifies keywords and contextual cues in text to determine the expressed sentiment orientation—positive, negative, or neutral. It is widely applied in user feedback analysis, public opinion monitoring, and related scenarios.

Intent classification ranks alongside sentiment analysis and named entity recognition as one of the most common downstream applications of LLMs.
The "classification result as routing condition" pattern reduces process complexity, but it also means classification errors are passed directly to subsequent actions.
情感分析的常见方法包括基于词典的规则匹配和基于预训练模型的分类器，前者轻量但精度有限，后者需要标注数据但准确度更高。
Soft capabilities such as conversational naturalness, knowledge accuracy, and genuine helpfulness are difficult to reflect in evaluation leaderboards but are most strongly felt in everyday use.
情感分析的学术源头可追溯至Pang等人2002年在ACL会议上发表的论文，该研究首次系统地将机器学习方法应用于电影评论的极性分类
