From Heart to Words: Generating Empathetic Responses via Integrated Figurative Language and Semantic Context Signals

Although generically expressing empathy is straightforward, effectively conveying empathy in specialized settings presents nuanced challenges.We present a conceptually motivated investigation into the use of figurative language and causal semantic context to facilitate targeted empathetic response generation within a specific mental health support domain, studying how these factors may be leveraged to promote improved response quality.Our approach achieves a 7.6% improvement in BLEU, a 36.7%reduction in Perplexity, and a 7.6% increase in lexical diversity (D-1 and D-2) compared to models without these signals, and human assessments show a 24.2% increase in empathy ratings.These findings provide deeper insights into grounded empathy understanding and response generation, offering a foundation for future research in this area.
