Annotation Methods Definition

Annotation methods refer to techniques used to label, tag, or code qualitative and quantitative data to make it structured, searchable and analyzable. In marketing research, annotation is commonly applied to text, audio, video, images and behavioral data to identify themes, sentiments, actions or attributes.

Annotation methods are the ways in which people organize data through labels and codes to create structure to otherwise long or convoluted information.
