Emoji ontology is a mac application that analyses emojis.
EmojiOntology adds the following meta-ata to emojis:
- Color analysis
- Usage number analysis
- Sentiment analysis
- Additional emoji annotation categories
It then converts the analysis to the following:
- CSV format
- OWL/XML ontology format
Code documentation can be found here on github pages.
The color analysis aims to get the dominant color for each emoji. It does that by using dither command in imageMagick utility.
The usage analysis calculates the usage of each emoji in twitter. The numbers are read and parsed from emojitracker.com.
The sentiment analysis aim to provide the sentiment for each emoji. The sentiment is calculated by analyzing the number of occurrence an emoji has been used in a negative, positive and neutral contexts.
When exporting to OWL, EmojiOntology applies an additional level of categories on the emoji annotations.
Exports the emoji meta-data to CSV file.
Exports the emoji ontology to OWL/XML format.
This is a list of files and what they represent
Annotation Categories.csv: This file contains the annotation additional categories, these categories help giving the emoji another depth in the ontology structure.
AnnotationCategories.xml: File containing a template OWL/XML file for all the additional category subclassing information.
FinalEmoji.owl: Final emoji ontology in OWL/XML format.
Emoji.owl: Emoji OWL main file template. This file contains placeholder string markers that EmojiOntology app fills when generating the final emoji.
EmojiColor.plist: Mac property list (mac dictionary) file that contains a hash map dictionary, with emoji as key and emoji dominant color as value.
EmojiFull.csv: CSV file containing a list of emoji and all the meta-data available for each emoji.
EmojiUses.plist: Mac property list (mac dictionary) file that contains a hash map dictionary, with emoji as key and emoji twitter usage numbers as value.
Sentiment.csv: CSV file containing the emoji base unicode information.
