Publications

  • Investigating the Representation of Backchannels and Fillers in Fine-tuned Language Models
    2025
    EMNLP (under review)
    Authors: Yu Wang, Leyi Lao, Langchu Huang, Gabriel Skantze, Yang Xu, Hendrik Buschmeier
    This work investigates how fine-tuning strategies enhance language models’ ability to represent and generate backchannels and fillers in dialogue. Empirical analyses demonstrate improved clustering quality and more human-like language generation, showcasing the potential for adapting general LMs into pragmatic-aware conversational models.
