Hi,  
Does ner.teach recipe work with a model made with span categorizer (spans.manual)? If not is there any way, to teach my model in order to enhance the prediction accuracy?

Thanks.

Hi @hmousa961 !

It won't work out-of-the-box because the `ner.teach` recipe is optimized for the entity recognizer which predicts non-overlapping spans in the `doc.ents`.

If you want to improve prediction accuracy, I suggest using [`spans.correct`](https://prodi.gy/docs/recipes#spans-correct). You can also pass the `--update` parameter if you want to annotate with a model in the loop.

Thank you so much for your reply. I will try the spans.correct with passing the --update.
