recastai-recognizer

An MS Bot Framework IIntentRecognizer implementation for Recast.ai

Prereqs

• Recast.ai node.js client, at least version 2
• MS Bot Framework node.js SDK - though not a technical dependency of this module.

Installation

npm install recastai-recognizer

usage

The recognizer is used in basically the same way as the LUIS recognizer plugin packaged with the MS Bot Framework SDK. It uses the Recast.ai node.js client module to communicate with your Recast.ai bot:

/*
 * The Recast.ai-specific bit
 */
var rairec = require('recastai-recognizer')
var recognizer = new rairec.RecastRecognizer(YOUR_TOKEN, YOUR_LANGUAGE)

/*
 * Standard MS Bot Framework stuff
 */
var builder = require('botbuilder')
var dialog = new builder.IntentDialog({ recognizers: [recognizer] });
var bot = new builder.UniversalBot(MS_BOT_FMWK_CONNECTOR)
bot.dialog('/', intents)

/*
 * Matching against one Recast.ai intent
 */
dialog.matches('YOUR_INTENT', function(session, args) {
    ...
}

/*
 * Matching against one of a number of Recast.ai intents
 */
dialog.matchesAny(['YOUR_INTENT_1', 'YOUR_INTENT_2' ...], function(session, args) {
    ...
}
...

• YOUR_TOKEN should be the client token string from your Recast.aia bot
• YOUR_LANGUAGE should be the language in which the utterenaces are made (e.g. "en" or "fr")

This allows the Recast.ai API to be used with the botbuilder intent matching facilities, making dialog and bot development with Recast.ai much more intuitive and closer to the recommended style of the botbuilder framework.

Notes

• Entity information from Recast.ai far exceeds that defined for the IEntity interface. Consequently, for each returned entity, the entity (string) property of the IEntity structure is set to the raw property of the Recast entity object, while an additional property, details, is set to the full Recast entity object.
• The full Recast response structure can be found in the recastResult property of the returned IIntentRecognizerResult object.

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. That said, my own style is rather old-school, so any improvements that retain compatibility with the minimum platform requirements of the Recast.ai framework are more than welcome.

Add unit tests for any new or changed functionality. Lint and test your code - some of which I've been particularly careful to observe in these early releases!
