botframework - Microsoft QnA 制造商是否使用 LUIS？

Question

我打算使用 QnA Maker，但它在后台使用 LUIS 吗？如果问题的提出方式与 QnA 制作者训练的方式不同，它会回应吗？

Answer 1

does it use LUIS in the background ?

不，但你可以 Combining Search, QnA Maker, and/or LUIS .

根据文档，建议通过以下三种方式将QnA与LUIS一起实现。

1. Call both QnA Maker and LUIS at the same time, and respond to the user by using information from the first one that returns a score of a specific threshold.

2. Call LUIS first, and if no intent meets a specific threshold score, i.e., "None" intent is triggered, then call QnA Maker. Alternatively, create a LUIS intent for QnA Maker, feeding your LUIS model with example QnA questions that map to "QnAIntent."

3. Call QnA Maker first, and if no answer meets a specific threshold score, then call LUIS.

这里我发布了一个用 C# 编写的第三种方法的代码示例。

在 MessagesController 中首先调用 QnA Maker:

if (activity.Type == ActivityTypes.Message)
{
    await Conversation.SendAsync(activity, () => new Dialogs.MyQnADialog());
}

在MyQnADialog中，查看是否有匹配的答案，如果没有，则调用LUIS:

[QnAMakerAttribute("QnASubscriptionKey", "QnAKnowledgebaseId", "No Answer in Knowledgebase, seraching in Luis...", 0.5)]
[Serializable]
public class MyQnADialog : QnAMakerDialog
{

    protected override async Task DefaultWaitNextMessageAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
    {
        if (result.Answers.Count == 0)
        {
            await context.Forward(new MyLuisDialog(), this.ResumeAfterNewOrderDialog, message, CancellationToken.None);
        }
        context.Wait(this.MessageReceivedAsync);
        //return base.DefaultWaitNextMessageAsync(context, message, result);
    }
    private async Task ResumeAfterNewOrderDialog(IDialogContext context, IAwaitable<object> result)
    {
        var resultfromnewdialog = await result;
        context.Wait(this.MessageReceivedAsync);
    }

}
