The Microsoft Azure AI Translator Service is an automatic translation tool that offers both single and batch text translation capabilities. Using this service, users can perform real-time translation of text and documents in more than 60 languages. It supports both Neural Machine Translation (NMT) and Statistical Machine Translation (SMT) models.
Understanding the Translator Service
Azure’s AI Translator Service uses Microsoft’s sophisticated AI technologies, which are continuously trained on a variety of texts from the web to provide high-quality translations. It is suitable for applications or services requiring text translation capabilities like multilingual customer support, e-learning platforms, or content localization.
To utilize the Translator service, you need to create a resource in Azure Portal. With the resource, you get an endpoint and a subscription key, both of which you will use to call the Translator service API. Make sure your data conforms to the service input requirements and consider the following:
- The length of the text must not exceed 5,000 characters.
- The content must be plain text. For documents, you are required to extract the plain text first.
Here is an example of how to use the Translator Service API with Python:
import requests
import uuid
import json
subscription_key = 'your_subscription_key'
endpoint = 'https://api.cognitive.microsofttranslator.com/'
path = '/translate'
params = '?api-version=3.0'
params = params + '&from=en'
params = params + '&to=fr'
full_url = endpoint + path + params
headers = {
'Ocp-Apim-Subscription-Key': subscription_key,
'Ocp-Apim-Subscription-Region': 'region',
'Content-type': 'application/json',
'X-ClientTraceId': str(uuid.uuid4())
}
body = [{'text': 'Hello World'}]
request = requests.post(full_url, headers=headers, json=body)
response = request.json()
print(json.dumps(response, sort_keys=True, indent=4, ensure_ascii=False, separators=(',', ': ')))
In this example, we send a POST request to the Translator service to translate ‘Hello World’ from English to French.
Translating Documents
Azure also offers Document Translation, which is a part of the Translator Service, to translate multiple documents at once while preserving the original formatting. You use a translation operation to submit a batch of documents and monitor the operation’s progress and results.
The steps involved in translating documents include:
- Document Input Configuration: Define the source and target languages and the SAS URL of the source documents.
- Start Translation: Submit the configured inputs to start translation and capture the operation ID for tracking.
- Monitor Progress and Retrieve Results: Use the operation ID to periodically check the status until completed.
Here’s a Python example summarizing these steps:
headers = {
'Ocp-Apim-Subscription-Key': subscription_key,
'Content-Type': 'application/json'
}
body = [
{
'source': { 'sourceUrl': 'source_SAS_URL' },
'targets': [
{'targetUrl': 'target_SAS_URL', 'language': 'fr'},
{'targetUrl': 'second_target_SAS_URL', 'language': 'de'}
]
}
]
response = requests.post('https://api.cognitive.microsofttranslator.com/translation/v1.0/batches',
headers=headers, json=body).json()
operation_id = response['id']
status_response = requests.get('https://api.cognitive.microsofttranslator.com/translation/v1.0/batches/{}'.format(operation_id),
headers=headers).json()
print(json.dumps(status_response, sort_keys=True, indent=4, ensure_ascii=False, separators=(',', ': ')))
In this code snippet, source_SAS_URL, target_SAS_URL, and second_target_SAS_URL carry references to the locations of the documents in Azure Blob Storage.
Conclusion
Microsoft Azure AI Translator Service is a powerful tool that offers seamless translation of text and documents across multiple applications. It is an essential part of many applications or services that require multilingual capabilities to foster better communication and improve user experiences. As an AI engineer preparing for the AI-102 exam, understanding this service will greatly boost your knowledge and practical skills in implementing Azure AI solutions.
