I have entity called “month” and lookup table that includes all months. I have enough nlu examples for the lookup table to work. I have also made synonyms for every month.

“February” has synonym “Februarys”. If user writes “Februarys” it will set the month to “February”.

**Problem:** If user writes “Februry” and it’s not in the synonyms it will be recognized as a month and it will be set as user has written it(typo).

I don’t want the entity to be mapped if there is a typo. If “Februry” or “Dcembers” is recognized it should be mapped to “February” or “December”, NOT as something that is close to the word.

I switched to CRFEntityExtractor. Now it works better. Seems like DIET entity recognition needs some fine tuning for me before i can use it.

Hello Kim, how did you manage to map “Februry” & “Dcembers” to “February” & “December” ? Thanks.
