Integrate Azure Database for PostgreSQL - Flexible Server with Azure Cognitive Services

Azure AI extension gives the ability to invoke the Azure AI Language Services such as sentiment analysis right from within the database.

Prerequisites

1. Enable and configure the azure_ai extension.
2. Create a Language resource in the Azure portal to get your key and endpoint.
3. After it deploys, select Go to resource.

Note

You will need the key, endpoint and region from the resource you create to connect the extension to the API.

Configure azure_ai extension with Azure Cognitive Services

In the Language resource, under Resource Management > Keys and Endpoint you can find the endpoint, keys, and Location/Region for your language resource. Use the endpoint and key to enable azure_ai extension to invoke the model deployment. The Location/Region setting is only required for the translation function.

select azure_ai.set_setting('azure_cognitive.endpoint','https://<endpoint>.cognitiveservices.azure.com');
select azure_ai.set_setting('azure_cognitive.subscription_key', '<API Key>');
-- the region setting is only required for the translate function
select azure_ai.set_setting('azure_cognitive.region', '<Region>');

Sentiment analysis

Sentiment analysis provides sentiment labels (negative,positive,neutral) and confidence scores for the text passed to the model.
