Guidelines on writing utterances for NLU

We recommend that you follow these basic guidelines when adding utterances for natural language understanding (NLU). Testing will indicate what else you need to do to improve the accuracy of the intention.

What is required

Add utterances that follow these guidelines:

• Are whole sentences or phrases that your users are likely to use
• Avoid single words if possible
• Do not add the same utterance to more than one intention
• Add entities so that Communicate can identify specific values in utterances. You only need one example per entity. Synonyms are optional.

What is not required

You do not need to add utterances to cover these cases:

• Variations of the main words that you expect to receive. This includes singles, plurals, different verb forms, and common typos.
• Letter case is ignored so that buy, Buy, BUY are all the same.
• Word order is ignored so the following are the same:
  • is it possible to order online
  • order is it possible online
