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.py

    Set the environment variables with your own values before running the sample:
    1) AZURE_LANGUAGE_ENDPOINT - the endpoint to your Language resource.
    2) AZURE_LANGUAGE_KEY - your Language subscription key
