are there any c# libraries for Named Entity Recognition? [closed]

Question

I am looking for any free libraries for Named Entity Recognition in c# or any other .net language.

Answer 1

If you just need to extract entities from text, you could try Open Calais from Thomson Reuters. It's free for up to 40K api calls/per day, and has worked well for me in the past. (I've been using it 2x/day for ~6 months without a hitch.)

They provide wrappers in various languages (for making api calls) and you can get the response in a few different formats as well.

Here's the link:

(I'm afraid I only know of NER libraries in Java and Python.)

Answer 2

SharpNLP, a port of the Java based OpenNLP, supports named entity tagging.
