nonMandarin

NonMandarin is a tag used in linguistics, data labeling, and language technology to indicate content, speech varieties, or datasets that do not involve the Mandarin Chinese language. It is not a formal linguistic category, but rather a practical label that can vary by context. In some studies and applications it denotes all varieties of Chinese other than Mandarin (for example, Cantonese, Wu, Min, Hakka, and others), while in data projects it may simply mean “not Mandarin” for filtering or classification purposes.

Scope and interpretation can differ. In linguistic work, nonMandarin may refer to the constellation of Chinese varieties that are not mutually intelligible with Mandarin and are often treated as separate languages or dialects within the Sinitic family. In computational contexts, nonMandarin often means any content that is not in Mandarin, which can include non-Chinese languages as well as non-Mandarin Chinese varieties. This ambiguity means the label should be defined explicitly in each project to avoid misclassification.

Applications and considerations. NonMandarin labeling is common in language identification, dataset curation, and model training when a project requires separation from Mandarin-specific resources. It is also relevant in education and sociolinguistics where researchers discuss regional or community languages and dialects outside Mandarin. However, the term can be imprecise due to the diversity within non-Mandarin varieties and the varying criteria used to distinguish languages from dialects.
