Top SchoolClaire Lesage is a Linguist Engineer and AI specialist based in San Francisco with nine years of experience applying computational linguistics to production NLP systems.

At Meta she leads a team of linguists, creates ontologies and high-quality training/test sets for NLU intent models, and trains new hires in annotation best practices.
