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
