AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A digital education provider wants to enhance its platform by converting lecture transcriptions into structured data so the platform can automatically categorize content and generate sentiment metrics that reflect the lecturers' tone. The solution must automatically discover relevant topics discussed in each lecture and analyze the overall sentiment. Which AWS managed service should be used to process and analyze the transcribed text?
Amazon Comprehend is a fully managed natural language processing (NLP) service that can discover topics in a collection of documents (topic modeling) and perform real-time sentiment analysis, key-phrase extraction, and other NLP tasks without requiring any machine-learning expertise. It converts unstructured text such as lecture transcripts into structured data for downstream analytics. Amazon Polly (text-to-speech), AWS Elemental MediaConvert (media transcoding), and Amazon Translate (machine translation) do not provide topic discovery or sentiment analysis capabilities on text.
