Azure AI document translation — Batch

Translate document in batch with Cognitive services

• Batch translate pdf document from one language to another

Use Case

• The below architecture shows how to do batch document translations
• Here i have translationinput as input container for document
• Then i created translationoutput as output container to store the output
• For both create SAS key with Read and write.
• At least read for translationinput
• Write for translationoutput

Architecture

 

Steps

• Create a new logic app
• Create a new workload
• create a new connection for blob storage where you have the data
• to trigger the flow start when a file is uploaded
• i am reading the pdf file — this step is not necessary

 

• Now drag HTTP to send the translation request
• Provide Ocp-Apim-Subscription-Key key which is from cognitive services
• then provide the URL

https://cognitivesvcname.cognitiveservices.azure.com/translator/text/batch/v1.0/batches

• Next configure the input and outputs
• Here i am converting to 2 different languages

{
  "inputs": [
    {
      "source": {
        "sourceUrl": "https://storagename.blob.core.windows.net/translateinput?sp=racwl&st=2020-10-19T21:27:53Z&se=2020-10-21T05:27:53Z&spr=https&sv=2020-08-04&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxx"
      },
      "targets": [
        {
          "language": "fr",
          "targetUrl": "https://storagename.blob.core.windows.net/translateoutput?sp=racwl&st=2020-10-19T21:29:02Z&se=2020-10-21T05:29:02Z&spr=https&sv=2020-08-04&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
        },
        {
          "language": "id",
          "targetUrl": "https://storaegname.blob.core.windows.net/translateoutput?sp=racwl&st=2020-10-19T21:29:02Z&se=2020-10-21T05:29:02Z&spr=https&sv=2020-08-04&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxx"
        }
      ]
    }
  ]
}

• source and targets are full blob sas keys
• the above SAS keys are fake and just for sample

 

• Next wait for 30 seconds

 

• Now lets get the status
• From the above batch submission, response header will have the URL to query for status

@{outputs('HTTP')['headers']?['Operation-Location']}

• Make sure send the Ocp-Apim-Subscription-Key

 

• Now save and run the logic app.
• Once successful then go out storage explorer and see the translationoutput container for processed pdf file.
• Done
