We built an NER model using Prodigy's ner.batch-train recipe. I am just thinking if I can open the predictions made by the model on the annotation tool again so that I can fix the prediction and start using them for improving the models further.
Yes, that's pretty much exactly the idea of the ner.make-gold workflow: you load a model, run it over the text, add the predicted entities as "spans" so you can view them all in the interface and edit them if necessary.
You can use the built-in recipe, or check out the implementation here to see how it works (and customise it if you want):
