|
* Analyze general tone. |

|
10
|
|
|
* Use the general purpose endpoint to analyze the tone of your input content. The service analyzes the content for |
|
11
|
|
|
* emotional and language tones. The method always analyzes the tone of the full document; by default, it also |
|
12
|
|
|
* analyzes the tone of each individual sentence of the content. |
|
13
|
|
|
* |
|
14
|
|
|
* You can submit no more than 128 KB of total input content and no more than 1000 individual sentences in JSON, plain |
|
15
|
|
|
* text, or HTML format. The service analyzes the first 1000 sentences for document-level analysis and only the first |
|
16
|
|
|
* 100 sentences for sentence-level analysis. |
|
17
|
|
|
* |
|
18
|
|
|
* Per the JSON specification, the default character encoding for JSON content is effectively always UTF-8; per the |
|
19
|
|
|
* HTTP specification, the default encoding for plain text and HTML is ISO-8859-1 (effectively, the ASCII character |
|
20
|
|
|
* set). When specifying a content type of plain text or HTML, include the `charset` parameter to indicate the |
|
21
|
|
|
* character encoding of the input text; for example: `Content-Type: text/plain;charset=utf-8`. For `text/html`, the |
|
22
|
|
|
* service removes HTML tags and analyzes only the textual content. |
