Misnota

Misnota is a term that has appeared in various discussions to describe incorrect notation, labeling, or annotation across different domains. It combines the prefix mis- with nota, from Latin nota meaning “mark” or “note.” There is no formal, universally accepted definition, and usage varies by disciplinary context.

In music, misnota can refer to a wrong note in a score or performance. It may result from transcription errors, misread manuscripts, or improvisational slips. Some writers treat misnota as a general category that includes wrong pitches, incorrect accidentals, or faulty rhythmic indications; others reserve the term for more ambiguous misreadings.

In data science and machine learning, misnota denotes mislabeled data points in training sets, such as an image of a cat labeled as dog. It highlights data quality issues that can degrade model performance and evaluation.

In linguistics and corpus annotation, misnota describes incorrect tagging of parts of speech, named entities, or syntactic roles, arising from human error or imperfect automatic tagging.

In digital archives and bibliographic metadata, misnota refers to wrong authorship, dates, titles, or other cataloging details, which can propagate across systems that rely on shared metadata.

Because misnota is not a standardized term, its exact meaning depends on context, and researchers typically prefer more established expressions like mislabeling, misannotation, or misnotation. See also misannotation, mislabeling, data quality.
