anti-synonyms for entities in Watson

We have synonyms in watson, and fuzzy matching - which works great!

But there are cases were  Watson selects completely wrong entities.

I have no way of fixing this.

My example case:
- user text contains the string 'Whats'   
- watson identifies a 70% match to   
      entity  @Doctor 
      value:  'Dr. Harish Bhat N' 
               with synonyms:
              "synonyms": [

                "Dr Haris",
                "Dr Haris Bhat N",
                "Haris",
               "Dr Haris N",
               "Bhat N",
               "Harish",
               "Dr. Bhat N",
               "Dr. Harish",
               "Dr. Harish Bhat N"
             ]

- we have fuzzy matching turned on, to match any mis-spelling cases



I am looking for a solution to help train watson - please don't consider 'Whats' as a match for this entity value.


My suggestion is to overload the  'synonyms' collection  to add with  a starting special character like '!'  ie, '!Whats'

      entity  @Doctor 
      value:  'Dr. Harish Bhat N'  
               with synonyms:
              "synonyms": [

                "Dr Haris",
                "Dr Haris Bhat N",
                "Haris",
               "Dr Haris N",
               "Bhat N",
               "Harish",
               "Dr. Bhat N",
               "Dr. Harish",
               "Dr. Harish Bhat N",
               "!Whats"        (this is the 'anti-synonym' case - where i can say the cases that should not be considered as a match)
             ]

This will mean minimal changes to your system - in terms of UI and others.

(maybe a global flag to say - this behaviour is on - ie, looking at the first character of the synonym)
