การกำหนดความรู้สึกของข้อความ ด้วย ข่าวสาร

Text sentiment analysis uses natural language processing (NLP) and machine learning to automatically determine the emotional tone of written content. Our system analyzes word choice, context, phrases, and linguistic patterns to classify text as positive, negative, or neutral with a confidence score.

Polarity indicates the direction of sentiment (positive, negative, neutral), while the sentiment score (0-1) measures intensity. A score of 0.9 with positive polarity indicates strongly positive content, while 0.5 suggests mildly positive or mixed sentiment.

Our models achieve 85%+ accuracy across general news categories, with specialized training for business, politics, technology, and entertainment content. Accuracy varies by domain—factual business news scores higher than opinion pieces with complex irony or sarcasm.
