How to give synonyms to an employee name lookup table?

I have created a lookup table of employee name text file referring to the rasa blog(link below).

Improving entity extractions with Rasa.

Now my use case also requires me to give synonyms to these employees in the lookup table. For example, “Nicholas” can also be referred to as “Nick” or “Nic”, so that the rasa bot can extract “nick” as “nicholas” and fulfill the use case.

Please advice how to achieve this.

Thanks

@tanay197 you would have to add those to your lookup table as well. If you then want to map that to the name “Nicholas” later you can use entity synonyms
