Dear colleague,
We are happy to announce the next webinar in the Language Technology
webinar series organized by The HiTZ Chair of Artificial Intelligence
and Language Technology (https://hitz.eus/katedra). We are organizing
one seminar every month.
Next webinar:
Speaker: Henning Wachsmuth (Leibniz University Hannover)
Title: Toward Argumentative Large Language Models
Date: Thursday, February 5, 2026 - 15:00
Summary: Today's large language models (LLMs) are optimized toward
giving helpful answers in response to prompts. In many situations,
however, it may be preferable for an LLM to foster critical thinking
rather than just following an instruction. While recent LLMs are said to
'reason', they barely build on established reasoning concepts known from
argumentation theory. In this talk, I will give insights into recent
efforts of my group in making LLMs more argumentative. Starting from
basics of LLM training processes, I will present how to specialize LLMs
for argumentation tasks via instruction fine-tuning as well as how to
align the arguments they generate using reinforcement learning. From
there, I will give an outlook on how to improve the actual reasoning
capabilities of LLMs.
Bio: Henning Wachsmuth leads the Natural Language Processing Group at
the Institute of Artificial Intelligence of Leibniz University Hannover.
After receiving his PhD from Paderborn University in 2015, he worked as
a PostDoc at Bauhaus-Universität Weimar and as a junior professor in
Paderborn, before he became a full professor in Hannover in 2022. His
group does basic research on large language models for computational
argumentation, social bias detection and mitigation, as well as
explainable and educational NLP. Henning's main research interests
include the generation of audience-aware text, the assessment of
pragmatic text quality, and the modeling of bias and framing.
