Querying an astronomical database using large language models: the ALeRCE text-to-SQL system

P. A. Estevez, J. Espejo-Moreira, S. Sanfeliu-Alvarez +10

We develop a text-to-SQL (structured query language) system based on large language models (LLMs) using in-context learning and apply it to the Automatic Learning for the Rapid Cla…
