Annotation Types
Potato ships 76 annotation types. These pages cover the ones most projects use, from radio buttons and Likert scales to spans, media, and agent traces.
An annotation type is the value of annotation_type in a scheme, and it decides what an annotator is asked to do with an item. Potato's registry has 76 of them.
The pages here cover the types most projects reach for. Radio and multiselect and Likert scales cover most labelling work. Span annotation and its relatives handle anything where the answer is a stretch of text rather than a whole item. The image, audio and video pages cover annotation over media. The comparison types, pairwise and best-worst, cover judgments that are easier to make relatively than absolutely.
Potato 2.12.0 added types for behavioural and social-science research and for the sciences: cloze passages, vocabulary tests, listening tests, list experiments and randomized response, ego networks, free lists and triad tests (cultural domain analysis), price lists, BDM bids and belief elicitation (incentive payments), interlinear glosses, spectrogram boxes, maps, and residue or variant selections on protein structures and genome loci. It also added volume_annotation for 3D medical volumes.
If you are still choosing between types rather than configuring one you have picked, Choosing an Annotation Scheme is the better place to start. The Study Designer generates valid YAML for all 76 types.
