On a similar note, I've a request for the HN community. Can anyone recommend a low-latency NER model/service.

I'm building an assistant that gives information on local medical providers that match your criteria. I'm struggling with query expansion and entity recognition. For any incoming query, I would want to NER for medical terms (which are limited in scope and pre-determined), and subsequently where I would do Query rewriting and expansion.
