AWS › AWS AI Services (Rekognition, Polly, Lex & Comprehend)

How can these AI services, such as Rekognition and Comprehend, be combined into a single automated workflow?

Intermediate

Answer

These AI services are commonly combined using event driven architectures, such as triggering a Lambda function whenever a new file is uploaded to S3, which then calls Rekognition to analyze an image or Comprehend to analyze a document's text, and the extracted insights can then be stored in a database, trigger further workflow steps through Step Functions, or generate notifications through SNS, all without requiring any dedicated machine learning infrastructure.

// Lambda function triggered by S3 upload
// calls Rekognition then stores results in DynamoDB
response = rekognition.detect_labels(image_s3_object)
dynamodb.put_item(response)

Real-world example An insurance company automatically analyzes photos submitted with a claim using Rekognition to detect vehicle damage, then uses Comprehend to analyze the accompanying written description for sentiment and key details, combining both results to help prioritize urgent claims.
