Unstructured data
Documents, free-text comments, images and audio can carry useful information but often require processing to extract features or categories. They may contain metadata; that does not make all their content structured. Assess privacy, bias and extraction errors before using results.
Worked example
An analyst categorises themes from customer comments, then checks a sample of the classifications against the original text.
Common mistake
Assuming that free text has no useful information or that automated categorisation is always accurate.
