DESCRIPTION:Abstract:\n\nContextual understanding is central to the perfor
 mance of Large Language Models\, yet it remains one of their most persiste
 nt challenges. In this talk\, I will explore how LLMs navigate (and often 
 fail to navigate) the complexities of context\, illustrated through two ca
 se studies: idiomaticity detection and fairness in identifying dehumanizin
 g language.\nIdiomaticity detection requires models to distinguish between
  literal and figurative meanings\, relying on nuanced contextual reasoning
 . Our experiments with a controlled contrastive dataset reveal that even s
 tate-of-the-art models struggle to resolve such ambiguities\, often failin
 g to attend to subtle contextual cues.\nIn the domain of fairness\, we inv
 estigate how LLMs identify dehumanizing language\, a critical task where u
 nderstanding social and linguistic contexts is key. Biases in the models
 ’ sensitivity to different protected attributes highlight an incomplete 
 grasp of the contexts in which dehumanization occurs\, underscoring ethica
 l implications for their deployment in sensitive applications.\nBy reading
  between the lines\, this talk shows the limitations of LLMs in contextual
  understanding across linguistic and ethical dimensions\n\n\nBio:\nDr. Naf
 ise Sadat Moosavi is a Lecturer in Natural Language Processing at the Univ
 ersity of Sheffield\, specializing in robust\, fair\, and trustworthy AI. 
 Her research focuses on the nuanced challenges of large language models\, 
 including reasoning\, efficiency\, robustness\, and fairness. Dr. Moosavi 
 earned her Ph.D. in Computational Linguistics from the University of Heide
 lberg. She has held senior roles in top NLP conferences\, including servin
 g as Senior Area Chair for ACL\, NAACL\, and EMNLP\, and has been the co-i
 nitiator and co-organizer of the SustaiNLP workshop series. As Deputy Dire
 ctor of Equality\, Diversity\, and Inclusion\, she leads initiatives to fo
 ster equity and inclusivity in academia.
