Abstract

Abstract:

LLMs contributed to a major breakthrough in NLP , both in terms of understanding natural language queries, commands or questions; and in generating relevant, coherent, grammatical, human-like text. LLMs like ChatGPT became a product used by many, for getting advice, writing essays, troubleshooting and writing code, creative writing, and more. This calls for a reality check: which NLP tasks did LLMs solve? What are the remaining challenges, and which new opportunities did LLMs create?

In this talk, I will discuss several areas of NLP that can benefit from but are still challenging for LLMs: grounding, i.e. interpreting language based on non-linguistic context; reasoning; and real-world applications. Finally, I will argue that the standard benchmarking and evaluation techniques used in NLP need to drastically change in order to provide a more realistic picture of current capabilities.
