• Abstract: Large Language Models (LLMs) demonstrate remarkable capabilities in text generation, yet their emotional consistency and semantic coherence in social media contexts remain insufficiently understood. This study investigates how LLMs handle emotional content and maintain semantic relationships through continuation and response tasks using two open-source models: Gemma and Llama. By analyzing climate change discussions from Twitter and Reddit, we examine emotional transitions, intensity patterns, and semantic similarity between human-authored and LLM-generated content. Our findings reveal that while both models maintain high semantic coherence, they exhibit distinct emotional patterns: Gemma shows a tendency toward negative emotion amplification, particularly anger, while maintaining certain positive emotions like optimism. Llama demonstrates superior emotional preservation across a broader spectrum of affects. Both models systematically generate responses with attenuated emotional intensity compared to human-authored content and show a bias toward positive emotions in response tasks. Additionally, both models maintain strong semantic similarity with original texts, though performance varies between continuation and response tasks. These findings provide insights into LLMs' emotional and semantic processing capabilities, with implications for their deployment in social media contexts and human-AI interaction design.

  DICE-Talk is a framework for disentangling identity with emotion and cooperating emotions with similar characteristics. We develop a disentangled emotion embedder that jointly models audio-visual emotional cues through cross-modal attention. Second, we introduce a correlation-enhanced emotion conditioning module with learnable Emotion Banks. Third, we design an emotion discrimination objective that enforces affective consistency during the diffusion process.

  Human emotions are often not expressed directly, but regulated according to internal processes and social display rules. No method to automatically classify different emotion regulation strategies in a cross-user scenario exists. We make use of the recently introduced textscDeep corpus for modeling the social display of the emotion shame. A fine-tuned Llama2-7B model is able to classify the utilized emotion regulation strategy with high accuracy.

• Exploiting Emotion-Semantic Correlations for Empathetic Response Generation [18.284296904390143]
  Empathetic response generation aims to generate empathetic responses by understanding the speaker's emotional feelings from the language of dialogue. Recent methods capture emotional words in the language of communicators and construct them as static vectors to perceive nuanced emotions. We propose a dynamical Emotion-Semantic Correlation Model (ESCM) for empathetic dialogue generation tasks.

  Emotion plays an essential role in human-to-human communication, enabling us to convey feelings such as happiness, frustration, and sincerity. This work investigated how emotion primitives can be used to detect categorical emotions such as happiness, disgust, contempt, anger, and surprise from neutral speech. Results indicated that arousal, followed by dominance was a better detector of such emotions.
