Definition
Domain data is data drawn from a specific field, such as law, medicine, finance, or code, rather than general web text. It is used to adapt a model to the vocabulary, conventions, and reasoning of that field, often through continued pretraining or fine-tuning. Adding domain data tends to improve accuracy and relevance on specialized tasks where general-purpose models fall short.
