CSML Studio allows you to use your own pre-trained Natural Language Processing (NLP) service directly in your CSML chatbots with very little configuration. You can easily setup your favorite NLP provider in Bot Settings > NLP:

When a NLP provider is configured, all text events will be sent to the NLP provider and returned either as a payload event if an intent is found, or untouched if no intent is found.

A few additional properties are set in the resulting event:

• event._nlp_provider: contains details about the NLP provider integration

• event._nlp_result: contains the raw response from the NLP provider request

• event._original_event: contains the original, untouched event. Only set if an intent is found.

Using NLP in your flows

You can now use the event by matching a found intent with a flow command, by setting that intent as one of the accepted commands for a flow:

Alternatively, you can also decide to match buttons or other actions within a flow with the found data. For instance, you can use NLP to detect a YES_INTENT and match it without having to list all the possible ways to say "yes" in the button's accepts array.

start:
​
  say Question(
    "Do you like chocolate?",
    buttons=[
      Button("Yes", accepts=["YES_INTENT"]) as btny,
      Button("No", accepts=["NO_INTENT"]) as btnn,
    ]
  )
  hold
  
  if (event match btny) say "I knew it!"
  else if (event match btnn) say "I think you are lying..."
  
  goto end
