Create a Solution using Azure Content Moderator
To set up a solution using Azure Content Moderator, follow the steps below:
- Create a Content Moderator resource: Start by creating a Content Moderator resource in the Azure portal. Log in to the Azure portal, search for Cognitive Services and then select “Content Moderator”.
- Configuring your resource: After selecting “Content Moderator”, you will have to configure your new resource. Assign it a name, choose a subscription, resource group and location according to your preference. ‘Pricing Tier’ can be chosen depending on your needs.
- Retrieve your keys and endpoints: After the resource is created, navigate to the resource page to obtain the ‘Key1’ and ‘Endpoint’ from the keys and endpoint section. These keys will be used to authenticate your application to the Azure Content Moderator.
- Use Azure Content Moderator APIs: You can now develop your application using the Azure Content Moderator APIs. These APIs are used to moderate content in images, text, and videos.
For example, to moderate text content, make a POST request to the https://
endpoint.
import requests
import json
text_content = {"data": "This is some text to moderate."}
headers = {
'Content-Type': 'text/plain',
'Ocp-Apim-Subscription-Key': '
}
response = requests.post('
print(response.json())
In the above example, replace <your-key> with the key of your Azure Content Moderator resource. Replace <your-endpoint> with the endpoint of your resource.
The response will contain the moderation results, showing if it found any profanity, personal data or any undesired content.
Azure Content Moderator is a practical tool for maintaining the health and safety of your content environment. Its automatic and extensive moderation capabilities make it a valuable resource to work with for any professional preparing to ace the AI-102 exam.
