npm install emoji-sentiment> Emoji sentiment data
- lightweight, easy to use JSON data with a minimalistic API
- based on the work of Kralj Novak, Petra; Smailović, Jasmina; Sluban, Borut and Mozetič, Igor, 2015, Emoji Sentiment Ranking 1.0, Slovenian language resource repository CLARIN.SI, http://hdl.handle.net/11356/1048.
- they engaged 83 human annotators to label over 1.6 million tweets in 13 european languages by sentiment polarity (negative, neutral or positive) while about 4% of the annotated tweets contained emoji
- this module provides transformed JSON data based on the original CSV data and derived data calculated in compliance with the original paper
Have a look at this table to see an example of what data this library provides.
Requiring/importing emoji-sentiment gives you the following data structure to work with:
``javascript`
[..., { / emoji sentiment datum / }, ...]
Array of emoji sentiment data.
Example of an emoji sentiment datum:
`javascript`
[
...
{
// original properties:
"sequence": "1F602",
"occurrences": 14622,
"negative": 3614,
"neutral": 4163,
"positive": 6845,
// derived properties:
"pNegative": 0.24717948717948718,
"pNeutral": 0.2847179487179487,
"pPositive": 0.4681025641025641,
"score": 0.22092307692307694,
"sem": 0.006751317877016391
},
...
]
Original properties are included in the JSON file whereas derived properties are being calculated on demand when the module is being required/imported.
Properties of an emoji sentiment datum explained:
- sequence (original)
normalized code point sequence (sequence without any variation selector or modifier applied) e.g. 1F602; use it for mapping the sentiment datum to a specific (emoji) unicode character or connecting it with further meta data (e.g. unicode-emoji-data, unicode-emoji-annotations or emoji-datasource)
- occurrences (original)
absolute number of occurrences of the (emoji) unicode character in tweets
- negative (original)
absolute number of occurrences of the (emoji) unicode character in tweets labeled negative
- neutral (original)
absolute number of occurrences of the (emoji) unicode character in tweets labeled neutral
- positive (original)
absolute number of occurrences of the (emoji) unicode character in tweets labeled positive
- pNegative (derived)
relative negativity component of the sentiment distribution for those tweets associated with the (emoji) unicode character, ranging from 0 to 1
- pNeutral (derived)
relative neutrality component of the sentiment distribution for those tweets associated with the (emoji) unicode character, ranging from 0 to 1
- pPositive (derived)
relative positivity component of the sentiment distribution for those tweets associated with the (emoji) unicode character, ranging from 0 to 1
- score (derived)
resulting sentiment score of the (emoji) unicode character, ranging from -1 to +1, calculated as the mean of the discrete sentiment distribution of negative (-1), neutral (0) and positive (+1)
- sem (derived)
precalculated Standard Error Mean for further deriving the confidence interval, e.g. for 95%:
[score − 1.96 sem, score + 1.96 sem]
The sum of negative, neutral and positive is occurrences.
The sum of pNegative, pNeutral and pPositive is 1.
