Tunizi: Tunisian Arabizi Sentiment Analysis Dataset

Tunizi is the first 100% Tunisian Arabizi sentiment analysis dataset. Tunisian Arabizi is the representation of the tunisian dialect written in Latin characters and numbers rather than Arabic letters.We gathered comments from social media platforms that express sentiment about popular topics. For this purpose, we extracted 100k comments using public streaming APIs.  Tunizi was preprocessed by removing links, emoji symbols, and punctuations.

The collected comments were manually annotated using an overall polarity:   positive (1), negative (-1) and neutral (0) class.   We divided the dataset into separate training, validation and test sets, with a ratio of 7:1:2  with a balanced split where the number of comments from positive class and negative class are almost the same.
