Sentiment Analysis
Sentiment analysis is the NLP technique of automatically identifying and classifying the emotional tone or opinion expressed in text, typically as positive, negative, or neutral, with varying degrees of granularity.
Understanding Sentiment Analysis
Sentiment analysis originated in product review analysis and social media monitoring but has broad applications in any domain where understanding emotional tone matters. In professional communication, sentiment provides urgency signals: an email with frustrated or urgent tone from a client warrants different handling than a routine update. Advanced sentiment models go beyond positive/negative/neutral to identify specific emotions such as frustration, excitement, urgency, and confusion, and can distinguish between sentiment about different entities within the same text.
How GAIA Uses Sentiment Analysis
GAIA uses sentiment analysis as one signal in its email triage system. A frustrated or urgent tone from a key contact elevates the priority of that email even if the subject line is neutral. This helps GAIA surface messages that need prompt attention based on emotional context, not just keywords or sender identity.
