Introduction
Identify and extract sentiment in given string. Sentiment analysis (also known as opinion mining) refers to the use of natural language processing, text analysis and computational linguistics to identify and extract subjective information in source materials. This algorithm takes an input string and assigns a sentiment rating in the range [-1 to 1] (very negative to very positive).

Input:
(Required): Key “document”, which contains a sentence or paragraph.
(Optional): Key “language”, for getting sentiment analysis for other languages. Default is (“en” for English). Can also use “auto” for automatically detecting language.
Note: for supported languages, please refer to the ISO-639-1 identifiers.

Note: sending a bare string instead of a JSON Object is deprecated from a previous version, and may yield unexpected results

Note: for batch, send as a list of objects

Output:
Sentiment value between -1 and 1 (very negative to very positive)
Examples
Example 1.
Parameter 1: Positive sentence.
{
“document”: “I really like eating ice cream in the morning!”
}
Output:

[
{
“sentiment”: 0.474,
“document”: “I really like eating ice cream in the morning!”
}
]
Example 2.
Parameter 1: Negative sentence.
{
“document”: “I really hate you, you are the worst!”
}
Output:

[
{
“sentiment”: -0.855,
“document”: “I really hate you, you are the worst!”
}
]
Example 3.
Parameter 1: Batch of sentences.
[
{
“document”: “I really hate you, you are the worst!”
},
{
“document”: “I really like eating ice cream in the morning!”
}
]
Output:

[
{
“sentiment”: -0.855,
“document”: “I really hate you, you are the worst!”
},
{
“sentiment”: 0.474,
“document”: “I really like eating ice cream in the morning!”
}
]
Example 4.
Parameter 1: Positive sentence in Turkish
Parameter 2: Auto detect language of text
Input:

{
“document”: “Algorithmia’yi cok seviyorum.”,
“language”: “tr”
}
Output:

[
{
“document”: “Algorithmia’yi cok seviyorum.”,
“sentiment”: 0.6369
}
]
Example 5.
Parameter 1: Negative sentence in French
Parameter 2: Autodetect language
Input:

{
“document”: “Je déteste les grenouilles”,
“language”: “auto”
}
Output:

[
{
“document”: “Je déteste les grenouilles”,
“sentiment”: -0.5719
}
]
