如何每天从QnA制造商那里获得前10个常见（趋势）问题？

Question

我想了解如何使用我的QnA制造商了解我的知识库中的前10个趋势或常见问题？在QnA中是否有任何参数或元数据键用于存储问题的频率？天蓝色的搜索可以帮到这里吗？请建议......

提前致谢！！

继Mick的答案之后，假设你已经为你的机器人的QnA认知服务启用了Application Insights，那么你可以在导航到Analytics page后使用下面的一个查询（详见Mick）：

它们可能不是最高性能或优化的查询，因为我只是修改了样本，直到我得到了我想要的。

// top questions in last 48 hours
requests
| where url endswith "generateAnswer" and timestamp > ago(48h) 
| project timestamp, id, name, resultCode, duration
| parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"
| join kind= inner (
traces | extend id = operation_ParentId
) on id
| extend question = tostring(customDimensions['Question'])
| summarize Count=count() by question
| top 100 by Count 
| project question, Count 


// top questions since timestamp
requests
| where url endswith "generateAnswer" and timestamp > datetime('2019-05-12 00:00:00')  
| project timestamp, id, name, resultCode, duration
| parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"
| join kind= inner (
traces | extend id = operation_ParentId
) on id
| extend question = tostring(customDimensions['Question'])
| summarize Count=count() by question
| top 100 by Count 
| project question, Count 


// top questions of all time
requests
| where url endswith "generateAnswer"  
| project timestamp, id, name, resultCode, duration
| parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"
| join kind= inner (
traces | extend id = operation_ParentId
) on id
| extend question = tostring(customDimensions['Question'])
| summarize Count=count() by question
| top 100 by Count 
| project question, Count 

作为奖励，您可以单击图表按钮，在查询运行后以图表形式查看信息。

如果您在创建QnA Maker服务期间启用了App Insights，QnA Maker会存储所有聊天记录和其他遥测。在this page上，您可以找到示例查询以从App Insights获取聊天记录。

示例查询

    requests
    | where url endswith "generateAnswer"
    | project timestamp, id, name, resultCode, duration
    | parse kind = regex name with *"(?i)knowledgebases/"KbId"/generateAnswer"
    | join kind= inner (
    traces | extend id = operation_ParentId
    ) on id
    | extend question = tostring(customDimensions['Question'])
    | extend answer = tostring(customDimensions['Answer'])
    | project KbId, timestamp, resultCode, duration, question, answer

您可以编写自定义查询来检索前10个常见问题/给出的答案。
