我如何使用QnAMaker为同一查询提供随机答案 [英] How can i use QnAMaker to provide random answers to same query

问题描述

我一直在思考，因为机器人有一些通用的问题，例如，你好吗?可能我有大约10个答案，我希望问与答制造商不能每次都选择相同的答案就随机选择.

I was thinking as bots have some generic questions like how are you ? may be i have around 10 answers which i would like Q&A maker to choose randomly not every time same answer.

或者还有其他类似问题，例如，告诉我一个故事

or also questions like tell me a story

推荐答案

一些通用问题，例如您好吗?可能我有大约10个答案，我希望问与答制造商不能每次都选择相同的答案就随机选择.

some generic questions like how are you ? may be i have around 10 answers which i would like Q&A maker to choose randomly not every time same answer.

要达到此要求，您可以尝试以下方法:

To achieve this requirement, you can try this approach:

1)添加一个QnA对，并使用特殊字符(例如|)来拆分问题how are you?

1) Add a QnA pair and use a special character (such as |) to split answers for question how are you?

2)覆盖RespondFromQnAMakerResultAsync方法，并在此方法中拆分响应并随机检索答案

2) Override the RespondFromQnAMakerResultAsync method, and split response and retrieve answer randomly in this method

protected override async Task RespondFromQnAMakerResultAsync(IDialogContext context, IMessageActivity message, QnAMakerResults result)
{
    // This will only be called if Answers isn't empty

    var response = result.Answers.First().Answer;
    var answersforhowareyou = response.Split('|');

    if (answersforhowareyou.Count() > 1)
    {
        Random rnd = new Random();
        int index = rnd.Next(answersforhowareyou.Count());

        response = answersforhowareyou[index];
    }

    await context.PostAsync(response);
}

测试结果:
