FILE: sample_recognize_entities_async.py
DESCRIPTION:
This sample demonstrates how to recognize named entities in a batch of documents.
In this sample, we own a catering business. We want to sort the reviews for our business
based off of which organization hired us.
USAGE:
python sample_recognize_entities_async.py
Set the environment variables with your own values before running the sample:
1) AZURE_TEXT_ANALYTICS_ENDPOINT - the endpoint to your Cognitive Services resource.
2) AZURE_TEXT_ANALYTICS_KEY - your Text Analytics subscription key
