Description

Inspects text and returns an inference of the prevailing sentiment (POSITIVE , NEUTRAL , MIXED , or NEGATIVE ).

Creating a Request

detectSentiment Source #

Arguments

:: Text	`dsText`
-> LanguageCode	`dsLanguageCode`
-> DetectSentiment

Creates a value of DetectSentiment with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

dsText - A UTF-8 text string. Each string must contain fewer that 5,000 bytes of UTF-8 encoded characters.
dsLanguageCode - The RFC 5646 language code for the input text. If you don't specify a language code, Amazon Comprehend detects the dominant language. If you specify the code for a language that Amazon Comprehend does not support, it returns and UnsupportedLanguageException . For more information about RFC 5646, see Tags for Identifying Languages on the IETF Tools web site.

Request Lenses

dsText :: Lens' DetectSentiment Text Source #

A UTF-8 text string. Each string must contain fewer that 5,000 bytes of UTF-8 encoded characters.

dsLanguageCode :: Lens' DetectSentiment LanguageCode Source #

The RFC 5646 language code for the input text. If you don't specify a language code, Amazon Comprehend detects the dominant language. If you specify the code for a language that Amazon Comprehend does not support, it returns and UnsupportedLanguageException . For more information about RFC 5646, see Tags for Identifying Languages on the IETF Tools web site.

Destructuring the Response

detectSentimentResponse Source #

Arguments

:: Int	`dsrsResponseStatus`
-> DetectSentimentResponse

Creates a value of DetectSentimentResponse with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

dsrsSentiment - The inferred sentiment that Amazon Comprehend has the highest level of confidence in.
dsrsSentimentScore - An object that lists the sentiments, and their corresponding confidence levels.
dsrsResponseStatus - -- | The response status code.
