Botframework-sdk: [QnA Maker] How to customize the "No match found!" message?

[iantje31]

Bot Info

• App ID: 8dd6a32f-bb28-4d73-8cc5-a58427ff1696
• SDK Platform: .NET
• SDK Version: QnAmaker
• Active Channels: WebChat, Microsoft Teams
• Deployment Environment: Azure Bot Service

Issue Description

I am trying to change the default message that is being sent when the bot can't find a match in the Knowledge Base. I searched online and found an article that said you need to change a line in the BasicQnAMakerDialog.cs file. When i change the code in that file, nothing happens.

Code Example

using System;
using System.Configuration;
using System.Linq;
using System.Threading.Tasks;
using System.Threading;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Dialogs;

using Microsoft.Bot.Builder.CognitiveServices.QnAMaker;

namespace Microsoft.Bot.Sample.QnABot
{
    // For more information about this template visit http://aka.ms/azurebots-csharp-qnamaker
    [Serializable]
    public class BasicQnAMakerDialog : QnAMakerDialog
    {
        // Go to https://qnamaker.ai and feed data, train & publish your QnA Knowledgebase.
        public BasicQnAMakerDialog() : base(new QnAMakerService(new QnAMakerAttribute(Utils.GetAppSetting("QnASubscriptionKey"), Utils.GetAppSetting("QnAKnowledgebaseId"), 'No good match in FAQ.', 0.5)))
        {}

Reproduction Steps

1. Type something random (for example: "gjksfgfs")
2. Send it to the bot
3. The bot replies with: "No match found!"

Expected Behavior

I expect the bot to reply: "No good match in FAQ"

Actual Results

The bot replies with "No match found!"

Hi @iantje31,

You can override RespondFromQnAMakerResultAsync in your dialog to customize the response from QnAMaker

protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
        {
            var answer = result.Answers.First().Answer;
            Activity reply = ((Activity)context.Activity).CreateReply();
            if (reply.Text.equals("Not Match Found!))
                 reply.Text = "No good match in FAQ";
            await context.PostAsync(reply);
        }

Or even better you can also change the default message when calling the constructor like this:

public BasicQnAMakerDialog() : base(new QnAMakerService(new QnAMakerAttribute(ConfigurationManager.AppSettings["QnASubscriptionKey"], ConfigurationManager.AppSettings["QnAKnowledgebaseId"], "No good match in FAQ")))

@FranciscoPonceGomez Thank you for your reply! I changed the code to the following:

using System;
using System.Configuration;
using System.Linq;
using System.Threading.Tasks;
using System.Threading;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Dialogs;

using Microsoft.Bot.Builder.CognitiveServices.QnAMaker;

namespace Microsoft.Bot.Sample.QnABot
{
    // For more information about this template visit http://aka.ms/azurebots-csharp-qnamaker
    [Serializable]
    public class BasicQnAMakerDialog : QnAMakerDialog
    {
        // Go to https://qnamaker.ai and feed data, train & publish your QnA Knowledgebase.
        public BasicQnAMakerDialog() : base(new QnAMakerService(new QnAMakerAttribute(Utils.GetAppSetting("QnASubscriptionKey"), Utils.GetAppSetting("QnAKnowledgebaseId"), 'No good match in FAQ.', 0.5)))
        {}
protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
        {
            var answer = result.Answers.First().Answer;
            Activity reply = ((Activity)context.Activity).CreateReply();
            if (reply.Text.equals("Not Match Found!))
                 reply.Text = "No good match in FAQ";
            await context.PostAsync(reply);
        }
    }
}

After i asked something that isn't a part of the knowledge base, i still get the message "No match found!"

After that i tried changing the code to this:

using System;
using System.Configuration;
using System.Linq;
using System.Threading.Tasks;
using System.Threading;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Dialogs;

using Microsoft.Bot.Builder.CognitiveServices.QnAMaker;

namespace Microsoft.Bot.Sample.QnABot
{
    // For more information about this template visit http://aka.ms/azurebots-csharp-qnamaker
    [Serializable]
    public class BasicQnAMakerDialog : QnAMakerDialog
    {
        // Go to https://qnamaker.ai and feed data, train & publish your QnA Knowledgebase.
        public BasicQnAMakerDialog() : base(new QnAMakerService(new QnAMakerAttribute(ConfigurationManager.AppSettings["QnASubscriptionKey"], ConfigurationManager.AppSettings["QnAKnowledgebaseId"], "No good match in FAQ")))
        {}
    protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
        {
            var answer = result.Answers.First().Answer;
            Activity reply = ((Activity)context.Activity).CreateReply();
            if (reply.Text.equals("No Match Found!))
                 reply.Text = "No good match in FAQ";
            await context.PostAsync(reply);
        }
    }
}

I tried to send the message again and still got: "No match found!"

Hi @iantje31,

The second options works just fine for me in local:

The QnAMakerDialog constructor accepts a threshold and a default message as optional parameters. This is the exact code that I have used:

    [Serializable]
    [QnAMakerSettings]
    public class SimpleQnADialog : QnAMakerDialog
    {
        [Serializable]
        public class QnAMakerSettingsAttribute : QnAMakerAttribute
        {
            public QnAMakerSettingsAttribute()
                : base(ConfigurationManager.AppSettings["QnASubscriptionKey"], ConfigurationManager.AppSettings["QnAKbId"], "Not good match found in FAQ", 0.5)
            {
            }
        }
    }

Please, bear in mind that if you are testing the final endpoint you need to redeploy your bot again.

Francisco

@FranciscoPonceGomez thank you for your very quick response!
I changed the dialog file to exactly what you have in the Azure Bot Service. But the result is still the same:

What do you mean exactly with redeploying? Do i need to create a new App Service Plan in Azure?

[FranciscoPonceGomez]

I am assuming that you are using ABS and making your changes in the online code editor, right?
In that case, any change you make in the editor need to be redeployed. To do that, click the console icon on the left vertical menu, type "build.cmd" in the console and hit enter. This action should build and deploy your code. Now you can go back to the test window and try again.

Francisco

@FranciscoPonceGomez it worked on the webchat! But when i type the same message in Microsoft Teams, the answer still is "No match found!" What can be the issue there?

[FranciscoPonceGomez]

Hi @iantje31,

Try restarting the web service in Azure:

Hi @FranciscoPonceGomez

I tried restarting the service in Azure, but the issue still occurs.

But after i made a new account on my enterprise E3 trail subscription and added the bot again the issue seems resolved. Is there any way to delete and add the bot again on an excisting account?

[FranciscoPonceGomez]

Hi @iantje31,

When you delete your bot, you will lose any updates you have made in your code. It is normally advisable to use Continuous Integration. In the "build" section of your bot service, you have the option to download your bot's code into a .zip file to open it later with Visual Studio, or add it to VSTS.

It is normally easier and faster to modify your code locally, test with the Bot Framework Emulator and when you are satisfied with the results, deploy to Azure.

Let me know if that works for you.
Francisco

[iantje31]

Hi @FranciscoPonceGomez ,

I indeed think it works better if i test the bot using the bot emulator before deploying it to Azure.

I was looking for a way to remove the bot from my Microsoft Teams 1:1 chats. Because when i create a new account in my Office 365 subscription and log in to teams with it, the new message is shown.

When i use my own account the old message appears.

[FranciscoPonceGomez]

Hi @iantje31,

Type "/deleteprofile" without "" and send the message. Restart MS Teams.
That should do the trick. Let me know if that worked.

Francisco

Hi @FranciscoPonceGomez,

That worked! :) Thanks a lot for your help! You guys are doing great with helping people!

How do I Transfer conversation from QnaMaker service to LUISDialog back again.
Problem statement (
LuisDialog --> QnaMakerDialog (works fine)
LuisDialog <--- QnaMaker (Once in QnaMaker Dialog, it does not route to LUISDialog)
Real Scenario:-
Hi - Invokes [Greeting] intent from LuisDialog.
weather today in Boston - Invokes [GetWeather] intent from LuisDialog.
How do i enroll myself-> Routes from LUISDailog [GetEnrolled] to QnaMakerDialog
After this User says (Hi, hello) which is the LUIS [Greeting] intent, seems it does not route from QnaMaker Dailog to LUISIntent.

Please advise, what's the best approach for the second route back from QnaMaker Dialog back to LuisDialog.

I'm having the same issue iantje31 initially had. I'm working locally and the Bot Emulator stills displays
"No match found!"
