Hello world.
I am using Azure Cognitive Services API to analysis each customer answers in our NPS forms, and return Key Phrases, according to this tutorial and it is working fine.
I also want a Sentiment Analysis score, and so I created another custom function to measure this, like the tutorial says:
(text) => let
apikey = "<MY_KEY>",
endpoint = "https://<MY_DENTPOINT_DOMAIN>.cognitiveservices.azure.com/" & "/text/analytics/v3.0/sentiment",
jsontext = Text.FromBinary(Json.FromValue(Text.Start(Text.Trim(text), 5000))),
jsonbody = "{ documents: [ { language: ""pt-br"", id: ""0"", text: " & jsontext & " } ] }",
bytesbody = Text.ToBinary(jsonbody),
headers = [#"Ocp-Apim-Subscription-Key" = apikey],
bytesresp = Web.Contents(endpoint, [Headers=headers, Content=bytesbody]),
jsonresp = Json.Document(bytesresp),
sentiment = jsonresp[documents]{0}[detectedLanguage][confidenceScore]
in sentiment
And all I got is errors like this:
Erro na consulta ‘’. Expression.Error: O campo 'detectedLanguage' do registro não foi encontrado.
Detalhes:
id=0
sentiment=positive
confidenceScores=
positive=0,99
neutral=0,01
negative=0
sentences=[List]
warnings=[List]
What could I do?

Hi @Anonymous ,
The devil is in the detail. There is an error in the custom function you created (it's actually incorrect in the tutorial).
It should be [confidenceScores] instead of [confidenceScore], so:
sentiment = jsonresp[documents]{0}[detectedLanguage][confidenceScores]
