Is there a way to highlight text in the relations annotation interface? The example linked here shows a spans attribute that labels the text. However, it seems like the label must be defined as a span-label, otherwise, it won't show up.
The use case for highlighting text is that the highlighted text serves as a way to easily identify some relations in the text. They act as cue words to signal that there may be a relation in the text. Therefore, I don't want to define them as a span-label, rather just be highlighted to the annotator.
I'm curious to understand a bit better why you can't use the spans key in the .json to help guide your labelling. The spans technically change the UI to make it more clear that there's something of interest, and the spans can be ignored by a spaCy model later in the pipeline. Is it the issue that you're also trying to train spans later?
