At a watson conversation I added a regular expression as entity:
(e.g. @LimitLiteral : (?i)(\d+(\,|.)\d*\s*[^,.;]\w\s*[^,.;]limit)|(limit\s*\d+(.|,)\d).
Inside this regexp you can find the constant limit. Is it possible to replace this constant limit with another entity?
(e.g. @limit , Limit, maximum , max, not more ..., less)
The advantage is that if possible the regexp can be maintained by adding a new value for the entity @Limit
thx
