You work as a machine learning specialist for a news organization with a very active online community that contributes comments on your organization’s news articles very frequently. Your news editors wish to use the comments from their users to gain insight into what interests them the most. Instead of just relying on the raw count of comments per article, the editors would like to use machine learning to find the underlying intent of the comments. This will allow them to understand their readers better to provide more tailored articles for the most popular subjects.
You have decided to use Amazon Comprehend as your machine learning platform for this task. Which of the listed Comprehend APIs would give you the information your editors have requested? (Select THREE)

Answer options:

A.CreateDocumentClassifier
B.DetectSentiment
C.DetectSyntax
D.DetectEntities
E.DetectKeyPhrases
F.DetectDominantLanguage

Answers: B, D, E
Option A is incorrect. The CreateDocumentClassifier Comprehend API creates a document classifier that you use to categorize documents. Your editors want you to find the underlying intent of the comments.
Option B is correct. The DetectSentiment Comprehend API gives you the underlying sentiment (positive, neutral, mixed, or negative) of a string, such as a comment.
Option C is incorrect. The DetectSyntax Comprehend API gives you the part of speech of each word in a string. This would not help you understand the underlying intent of a comment.
Option D is correct. The DetectEntities Comprehend API finds named entities in text. This would help you find entities such as a news organization, politicians, celebrities, companies, etc. This information will help you identify the subject matter of the comments.
Option E is correct. The DetectKeyPhrases Comprehend API finds key noun phrases in the text. This will also help you identify the subject matter of a comment.
Option F is incorrect. The DetectDominantLanguage Comprehend API finds the language (English, French, Spanish, etc.) used most frequently in the comments. This would not offer you much insight into the intent of a comment.
