🤖 AI Summary
Metalinguistic phenomena in natural language processing have long lacked a systematic definition and dedicated research. This work addresses this gap by formally delineating the notion of metalinguistic capability within NLP through conceptual analysis and a comprehensive literature review. It proposes a four-dimensional analytical framework encompassing form, function, tasks, and evaluation, which systematically organizes existing research and uncovers several overlooked directions. The framework not only clarifies the relationship between metalinguistic abilities and large language models but also offers a structured pathway for future investigations, thereby advancing the theoretical formalization and task standardization of metalinguistics in NLP.
📝 Abstract
This work aims to shine a spotlight on the topic of metalanguage. We first define metalanguage, link it to NLP and LLMs, and then discuss our two labs' metalanguage-centered efforts. Finally, we discuss four dimensions of metalanguage and metalinguistic tasks, offering a list of understudied future research directions.
