How to communicate single Bot with two differnet QnA Data sets based on user requrest? - bots

Question

How to communicate Single ChatBot with different QnA data sets(JSON)..
Ex :
QnA1 (JSON file)
QnA2 (JSON file)
and Single Bot application.
when I launch the with site1, Bot will communicate to QnA1 data.
when I launch the with site2, Bot will communicate to QnA2 data.
Here I have only one Bot.
please let me know how to pass KNOWLEDGE_BASE_ID to Bot.

Answer 1

when I launch the with site1, Bot will communicate to QnA1 data. when I launch the with site2, Bot will communicate to QnA2 data.
The UI of BotFramework are based on Dialog, so I can only guess that your site 1 and site 2 means two dialogs and each dialog are built based on QnA.
please let me know how to pass KNOWLEDGE_BASE_ID to Bot.
Then to pass KNOWLEDGE_BASE_ID to your bot, you can use QnAMakerAttribute for your dialog. In .Net SDK for example:
[QnAMakerAttribute("Your-subscription-key", "Your-Qna-KnowledgeBase-ID", "No Answer in Knowledgebase.", 0.5)]
[Serializable]
public class QnADialog1 : QnAMakerDialog
{
}
And if you're using node.js SDK for development, you can pass the id like this:
var recognizer = new builder_cognitiveservices.QnAMakerRecognizer({
knowledgeBaseId: 'Your-Qna-KnowledgeBase-ID', // process.env.QnAKnowledgebaseId,
subscriptionKey: 'Your-Qna-KnowledgeBase-Password'}); //process.env.QnASubscriptionKey});
For more information, you can refer to the Blog samples, there're both C# and node.js version of demos.
If you still want to ask how to use two knowledge-bases in one bot, please leave a comment and tell me which sdk are you using for development, .net or node.js? I will come back and update my answer.
UPDATE:
You can code for example like this:
[Serializable]
public class RootDialog : IDialog<object>
{
private string currentKB;
public Task StartAsync(IDialogContext context)
{
context.Wait(MessageReceivedAsync);
return Task.CompletedTask;
}
private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
var activity = await result as Activity;
if (activity.Text == "reset") //handle reset
currentKB = null;
else if (activity.Text == "qna1" || currentKB == "qna1")
{
currentKB = "qna1";
if (activity.Text == "qna1")
await context.PostAsync("this is qna 1");
else
await context.Forward(new Dialogs.QnADialog1(), this.QnAReceivedAsync, activity, CancellationToken.None);
}
else if (activity.Text == "qna2" || currentKB == "qna2")
{
currentKB = "qna2";
if (activity.Text == "qna2")
await context.PostAsync("this is qna 2");
else
await context.Forward(new Dialogs.QnADialog2(), this.QnAReceivedAsync, activity, CancellationToken.None);
}
else
{
var reply = activity.CreateReply("Please choose a knowledge base...");
var heroCard = new HeroCard
{
Title = "Knowledge bases",
Text = "Which one do you want to choose?",
Buttons = new List<CardAction>
{
new CardAction(ActionTypes.ImBack, "QnA base 1", value:"qna1"),
new CardAction(ActionTypes.ImBack, "QnA base 2", value:"qna2")
}
};
Attachment attachment = heroCard.ToAttachment();
reply.Attachments.Add(attachment);
await context.PostAsync(reply);
context.Wait(MessageReceivedAsync);
}
}
public async Task QnAReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
context.Wait(MessageReceivedAsync);
}
}
And in the MessagesController make the RootDialog as the root of dialog stack:
if (activity.Type == ActivityTypes.Message)
{
await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
}
Finally by QnADialog1 and QnADialog2, I only passed knowledge base ID and key there.
