How to automatically train the Knowledge Base (QnAMaker Service)?

Question

In the QnA Maker Service provided by the Microsoft's Cognitive Services, we can train our KB (Knowledge Base) by manually inserting the QnA pairs.

Is there a way to automate this process so that we can always keep our KB up-to-date please? There is an API documentation but i cannot find one for this purpose

Answer 1

The new V2.0 APIs let you programmatically manage your knowledge base. Now you can do the following with the APIs:

• Create knowledge base
• Delete knowledge base
• Update knowledge base
• Download knowledge base
• Publish knowledge base

Answer 2

I have created a bot that will automatically update the QnA Maker KB. Currently supports Add operation, where you add QnA pairs in the KB and publish it. I used QnA Maker client library using C#. You can find the documentation here.

On providing the qna pairs by the user, I am calling the Client library.

if ((bool)stepContext.Result)
        {
            await stepContext.Context.SendActivityAsync(MessageFactory.Text("Here are the details you provided."), cancellationToken);

            await stepContext.Context.SendActivityAsync(MessageFactory.Text("Questions - "), cancellationToken);

            for (int i = 0; i < QnAData.QuestionPhrase.Count; i++)
            {
                await stepContext.Context.SendActivityAsync(MessageFactory.Text(QnAData.QuestionPhrase[i]), cancellationToken);
            }


            await stepContext.Context.SendActivityAsync(MessageFactory.Text("Answer - " + (string)stepContext.Values["Answer"]), cancellationToken);

            await stepContext.Context.SendActivityAsync(MessageFactory.Text("Please wait while I update your Knowledge Base."), cancellationToken);

            var authoringURL = $"https://{Configuration["ResourceName"]}.cognitiveservices.azure.com";

            // <AuthorizationAuthor>
            var client = new QnAMakerClient(new ApiKeyServiceClientCredentials(Configuration["Key"]))
            { Endpoint = authoringURL };
            // </AuthorizationAuthor>

            QnAClient.UpdateKB(client, Configuration["KnowledgeBaseId"], (string)stepContext.Values["Answer"]).Wait();
            QnAClient.PublishKb(client, Configuration["KnowledgeBaseId"]).Wait();

            await stepContext.Context.SendActivityAsync(MessageFactory.Text("I have added your qna pair in the Knowledge Base. Thank you for using QnA Updator Bot Service."));

            return await stepContext.EndDialogAsync(null, cancellationToken);
        }
        else
        {
            await stepContext.Context.SendActivityAsync(MessageFactory.Text("Request Not Confirmed."));
            return await stepContext.EndDialogAsync(cancellationToken: cancellationToken);
        }
