Kathleen McKeown, Columbia University

Large language modeling has changed the nature of natural language processing, with striking success in a large variety of tasks. Despite this success, failures exist, raising questions about their readiness for real use. In this talk I explore two problems for large language models: hallucination and bias. I discuss hallucination in the context of summarization and I present bias in the context of understanding African American Language.
