    paper Emotion-Aware Response Ranking System

    This project introduces an advanced response ranking mechanism for emotionally sensitive conversational AI systems. The architecture integrates emotion intensity scoring and contextual relevance via a weighted formula to generate empathetic and context-aware responses.

    The system aims to:

    Enhance empathetic dialogue using emotional intensity and classification.
    Optimize response selection by balancing factual relevance and emotional alignment.
    Track emotional change in users over time, supporting mental health and emotional growth.
