Can Prodigy enable you to assign multiple categories to entire paragraphs or sentences?
Yes, the text classifier supports multi-label classification (actually this is the default). So you can use label schemes that aren’t mutually exclusive.
In terms of doing the annotation, I would recommend you annotate each label separately, and make several passes over your data. This lets the active learning work better, because at each point the model only asks you about cases which might be the label you’re working with. It also makes the annotation much more efficient, because there’s a single click for each decision. If you do prefer to apply all the labels at once though, you can use the choice interface.
Thanks!
