Summary

In this chapter, we started with high-level concepts around Amazon AI services and serverless computing. On a conceptual level, you learned about serverless computing as well as the various AI services available on the AWS platform.

Overall, the culmination of these independent functions provides the foundation for building complex machine learning-based NLP applications (for example, Siri, Alexa, and so on). Knowing how and why the individual functions operate will allow you to build your own AWS-based NLP applications.

Then, we dived into the details of Amazon Comprehend—how Comprehend's DetectDominantLanguage method is structured, and how to pass in both strings and a list of strings. You learned how to extract entities, sentiments, key phrases, and topics, which provide the data for complex NLP. This allows Amazon Comprehend to become more efficient by automating text analysis upon a text document that's been uploaded to S3.
