Text translation API can dynamically translate the different languages:
In this post, I am going to use Yandex Translate Text API to translate chatter feed(text). It uses a hybrid model of machine translation that includes both neural network (deep learning) and statistical approaches.
Yandex Translate Text API is a free API that we can use for translation. You just need to signup to get APIKEY.
API Request syntax:
https://translate.yandex.net/api/v1.5/tr.json/translate
? key=<API key>
& text=<text to translate>
& lang=<translation direction>
& [format=<text format>]
& [options=<translation options>]
& [callback=<name of the callback function>]
| Query Parameters | Description |
| key | APIKEY: It is issued free of charge. |
| text | The text to translate. You can use multiple text parameters in a request. The source text must be URL-encoded. |
| lang | The translation direction. You can set it in either of the following ways: As a pair of language codes separated by a hyphen (“from”-“to”). For example, en-hi indicates translating from English to Hindi. |
| format | Text format. plain – Text without markup (default value). html – Text in HTML format. |
| options | The only option available at this time is whether the response should include the automatically detected language of the text being translated. This corresponds to the value 1 for this parameter. |
| callback | The name of the callback function. Use for getting a JSONP response. |
