Microsoft Bot Framework: using a LuisDialog for processing intents

- 2 mins

In the previous post, I blogged about integrating a Holographic 2D app with Bot Framework and LUIS.

I also spent some time going through these great samples for some presentations and found a very nice implementation for handling the Bot messages when LUIS intents are recognised.

Instead of using the exposed LUIS endpoint and parsing the returned JSON, the framework already provides a specific LuisDialog<> type which can be used for handling the various intents, in order to make the code cleaner and more extensible.

I've then modified the HoloLensBotDemo sample and added a new RootLuisDialog:

[LuisModel("YourModelId", "YourSubscriptionKey")]
[Serializable]
public class RootLuisDialog : LuisDialog<object>
{
    [LuisIntent("")]
    [LuisIntent("None")]
    public async Task None(IDialogContext context, LuisResult result)
    {
        var errorResult = "Try something else, please.";
        await context.PostAsync(errorResult);
        context.Wait(this.MessageReceived);
    }

    [LuisIntent("FavouriteTechnologiesIntent")]
    public async Task FavouriteTechnologiesIntent(IDialogContext context, IAwaitable&lt;IMessageActivity&gt; activity, LuisResult result)
    {
        await context.PostAsync("My favourite technologies are Azure, Mixed Reality and Xamarin!");
        context.Wait(this.MessageReceived);
    }

    [LuisIntent("FavouriteColorIntent")]
    public async Task FavouriteColorIntent(IDialogContext context, IAwaitable&lt;IMessageActivity&gt; activity, LuisResult result)
    {
        await context.PostAsync("My favourite color is Blue!");
        context.Wait(this.MessageReceived);
    }

    [LuisIntent("WhatsYourNameIntent")]
    public async Task WhatsYourNameIntent(IDialogContext context, IAwaitable&lt;IMessageActivity&gt; activity, LuisResult result)
    {
        await context.PostAsync("My name is Davide, of course :)");
        context.Wait(this.MessageReceived);
    }

    [LuisIntent("HelloIntent")]
    public async Task HelloIntent(IDialogContext context, IAwaitable&lt;IMessageActivity&gt; activity, LuisResult result)
    {
        await context.PostAsync(@"Hi there! Davide here :) This is my personal Bot. Try asking 'What are your favourite technologies?'");
        context.Wait(this.MessageReceived);
    }
}

And this is all the code now needed for the Bot.

The updated source code is available on GitHub.

Happy coding!
