Sentiment Analysis
Click any concept to expand the technical explanation. Written in beginner-friendly language.
Sentiment analysis is the process of using AI to identify and extract subjective information from text — determining whether the expressed opinion is positive, negative, or neutral.
NLP is a branch of AI that enables computers to understand, interpret, and generate human language. It bridges the gap between human communication and machine understanding.
Text classification assigns predefined categories to text documents. In sentiment analysis, this means labelling text as positive, negative, or neutral based on its content.
Emotion detection goes beyond sentiment polarity to identify specific emotional states — joy, trust, fear, anger, sadness, disgust, surprise, and anticipation.
Keyword extraction identifies the most significant words and phrases in a text, revealing the main topics, concerns, and themes expressed by the author.
AI insight generation synthesises analysis results into human-readable summaries and actionable recommendations, making complex data accessible to non-technical users.
