Q: What kinds of data does the solution ingest?

A:  The solution supports multi-source ingestion. It provides implementation for the following three sources of ingestion 1) Twitter, 2) Public RSS feeds from across ~4,000 news sites worldwide, and 3) YouTube video comments. The solution can be customized to ingest other digital assets from social media platforms or internal systems within organizations.

Using the Search API, customers can not only search for terms in a tweet's text, but also use additional filters supported by Twitter’s API—such as place and geo-coordinates. With RSS feeds, the solution can be configured to ingest different topics including: tech, news, business, science, finance, food, politics, economics, travel, entertainment, music, and sports and filter them further to look for specific terms within the RSS feeds. With YouTube comments, you can perform natural language processing (NLP) analysis on user comments on videos created for your product launches, advertorials, movie trailers, and others to understand customer sentiment.

Q: What machine learning inferences does the solution provide?

A: The solution ingests text and images. If ingested data does not contain a pre-defined language code, the solution detects the language using Amazon Comprehend, and translates non-English texts to English using Amazon Translate. Using AWS Comprehend, it performs topic modeling, sentiment analysis, entity detection, and key phrase detection on text. Through Amazon Rekognition, the solution can detect embedded text and content moderation labels in images. The detected text within an image is also subject to topic modeling, sentiment analysis, entity detection, and key phrase detection. An AWS Step Functions function orchestrates these machine learning services.

Q: Can I deploy the solution in any AWS Region?

A: No, this solution uses Amazon Comprehend, Amazon Rekognition, Amazon Translate, and Amazon EventBridge, which are currently available in specific AWS Regions only. Therefore, you must launch this solution in an AWS Region where these services are available. For the most current availability by Region, refer to the AWS Regional Services List.
