Motivation
On social media, Arabic speakers tend to express themselves in their own local dialect. To do so, Tunisians use “Tunisian Arabizi”, which consists in supplementing numerals to the Latin script rather than the Arabic alphabet.
In the African continent, analytical studies based on Deep Learning are data hungry. To the best of our knowledge, no annotated Tunisian Arabizi dataset exists.
Twitter, Facebook and other micro-blogging systems are becoming a rich source of feedback information in several vital sectors, such as politics, economics, sports and other matters of general interest. Our dataset is taken from people expressing themselves in their own Tunisian Dialect using Tunisian Arabizi.
TUNIZI is composed of one instance presented as text comments collected from Social Media, annotated as positive, negative or neutral. This data does not include any confidential information. However, negative comments may include offensive or insulting content.
TUNIZI dataset is used in all iCompass products that are using the Tunisian Dialect. TUNIZI is used in a Sentiment Analysis project dedicated for the e-reputation and also for all Tunisian chatbots that are able to understand the Tunisian Arabizi and reply using it.
Team
TUNIZI Dataset is collected, preprocessed and annotated by iCompass team, the Tunisian Startup speciallized in NLP/NLU. The team composed of academics and engineers specialized in Information technology, mathematics and linguistics were all dedicated to ensure the success of the project. iCompass can be contacted through emails or through the website: www.icompass.tn
Implementation
- Data Collection: TUNIZI is collected from comments on Social Media platforms. All data was directly observable and did not require other data to be inferred from. Our dataset is taken from people expressing themselves in their own Tunisian Dialect using Arabizi. This dataset relates directly to Tunisians from different regions, different ages and different genders. Our dataset is collected anonymously and contains no information about users identity.
- Data Preprocessing & Annotation: TUNIZI was preprocessed by removing links, emoji symbols and punctuation. Annotation was then performed by five Tunisian native speakers, three males and two females at a higher education level (Master/PhD).
- Distribution and Maintenance: TUNIZI dataset is made public for all upcoming research and development activitieson Github. TUNIZI is maintained by iCompass team that can be contacted through emails or through the Github repository. Updates will be available on the same Github link.
- Conclusion: As the interest in Natural Language Processing, particularly for African languages is growing, a natural future step would involve building Arabizi datasets for other underrepresented north African dialects such as Algerian and Moroccan.
