Hi @prathap9000

the spacy_sklearn pipeline uses the CRFEntityExtractor which is documented as working good with custom defined entities. If you want to achieve the model to be able to extract varieties of those entities at the same or similar positions, I’d suggest to use a lookup table.

Keep in mind that even for a lookup table you’ll need certain training samples containing a variety of entities.
