Language corpora make up a subdomain of all text corpora, which are sets of texts (usually large, unstructured, and electronically stored and processed) that are used to do statistical/computational research and analysis, testing, and algorithm training. The term language corpus may refer generally to any collection of linguistic data (written, spoken, signed, or multimodal) or more specifically to collections that have been organized or collected with a particular end in view (e.g., to characterize one or more languages).
