FILE: sample_extract_summary.py
DESCRIPTION:
This sample demonstrates how to submit text documents for extractive text summarization.
Extractive summarization is available as an action type through the begin_analyze_actions API.
USAGE:
python sample_extract_summary.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

"At Microsoft, we have been on a quest to advance AI beyond existing techniques, by taking a more holistic, "
"human-centric approach to learning and understanding. As Chief Technology Officer of Azure AI Cognitive "
"Services, I have been working with a team of amazing scientists and engineers to turn this quest into a "
"reality. In my role, I enjoy a unique perspective in viewing the relationship among three attributes of "
"human cognition: monolingual text (X), audio or visual sensory signals, (Y) and multilingual (Z). At the "
"intersection of all three, there's magic-what we call XYZ-code as illustrated in Figure 1-a joint "
"representation to create more powerful AI that can speak, hear, see, and understand humans better. "
"We believe XYZ-code will enable us to fulfill our long-term vision: cross-domain transfer learning, "
"spanning modalities and languages. The goal is to have pretrained models that can jointly learn "
"representations to support a broad range of downstream AI tasks, much in the way humans do today. "
"Over the past five years, we have achieved human performance on benchmarks in conversational speech "
"recognition, machine translation, conversational question answering, machine reading comprehension, "
"and image captioning. These five breakthroughs provided us with strong signals toward our more ambitious "
"aspiration to produce a leap in AI capabilities, achieving multisensory and multilingual learning that "
"is closer in line with how humans learn and understand. I believe the joint XYZ-code is a foundational "
"component of this aspiration, if grounded with external knowledge sources in the downstream AI tasks."
