I am facing a problem with entity extraction for a entity “Company\_Name”.

One variant of example : what are the current assets for Alpha Steels company.

Alpha Steels is a company name. there would be a hundred company names in my list.

shall i add examples for all the companies or lookup would help me out to solve this issue? and Do i need to add any options to the ner\_crf pipeline.

I just wanted to know before implementing lookup.
