Natural language holds a wealth of information like user sentiment and conversational intent. In this session, we'll demonstrate the capabilities of Amazon Comprehend, a natural language processing (NLP) service that uses machine learning to find insights and relationships in text. We'll show you how to build a VOC (Voice of the Customer) application and integrate it with other AWS services including AWS Lambda, Amazon S3, Amazon Athena, Amazon QuickSight, and Amazon Translate. We’ll also show you additional methods for NLP available through Amazon Sagemaker. Level: 200-300 Speaker: Gopal Wunnava - Principal Solutions Architect, AWS

12. Easy to Use & Integrate
• Use through Command Line Tools or AWS SDKs
• Integrate into your application or call externally
• Python example:
import boto3
Amazon.translate = boto3.client(service_name=‘translate')
result = Amazon.translate(Text="Hello, World",
SourceLanguageCode="en", TargetLanguageCode="de")
print('TranslatedText: ' + result.get('TranslatedText'))
