Recognize the user input inside the handler function using dialogflow.ai/api.ai and Microsoft Bot Builder

I am building a bot using the given technology stacks:

  1. Microsoft Bot Builder
  2. Node.js
  3. Dialogflow.ai (api.ai)

We used waterfall model to implement a matched intent Dialog, which includes a couple of handler functions and prompts. After following this scenario I need to identify the entities inside an inner handler function, for a user input.

eg:

Bot : Where do you want to fly?

User: Singapore. (For this we added entities like SIN - Singapore,SIN(Synonym), So I need to resolve the value as SIN)

Any help on this scenario is much appreciated.

Here is a post Using api.ai with microsoft bot framework you can refer for your reqirement, and with a sample at https://github.com/GanadiniAkshay/weatherBot/blob/master/api.ai/index.js. The weather api key leveraged in this sample is out of date, but the waterfall and recognizer api key is still working.

Generally speaking:

  • Use api-ai-recognizer

  • Instantiate the apiairecognizer and leveraged builder.IntentDialog to include the recognizer:

     var recognizer = new apiairecognizer("<api_key>");
 var intents = new builder.IntentDialog({
     recognizers: [recognizer]
 });
  • In IntentDialogs, use builder.EntityRecognizer.findEntity(args.entities,'<entity>'); to recognize the intent entities.
