FILE: sample_analyze_actions_async.py
DESCRIPTION:
This sample demonstrates how to submit a collection of text documents for analysis, which consists of a variety
of text analysis actions, such as Entity Recognition, PII Entity Recognition, Linked Entity Recognition,
Sentiment Analysis, Key Phrase Extraction and more.
The response will contain results from each of the individual actions specified in the request.
USAGE:
python sample_analyze_actions_async.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
