How to vary language in narratives
In Arria NLG Studio, there are two ways to add variation: random and controlled.
Random variation
Things vary freely:
structure = chooseAtRandom(1, 2)
Controlled variation
Things vary based on a rule:
[[isFirstSentence == true ? "in [[reference(entity, true)]] " : '']]
