Resources building for sentiment analysis on content disseminated by Tunisian media in social networks

Résumé

Abstract Nowadays, social networks play a fundamental role in promoting and diffusing television and radio programs to different categories of audiences. So, political parties, influential groups and political activists have rapidly seized these new communication media to spread their ideas andgive their sentiments concerning critical issues. In this context, Twitter, Facebook and YouTube have become very popular tools for sharing videos and communicating with users who interact with each other to discuss some problems, propose solutions and give viewpoints. This interaction on the social media sites yields to a huge amount of unstructured and noisy texts; hence the need for automated analysis techniques to classify sentiments conveyed in the users’ comments. In this work, we focus on opinions written in a less resourced Arabic language: Tunisian dialect (TD). In this work, we present a process for building a sentiment analyses model for comments written on Tunisian television broadcasts published in social media. These comments are written in a particular way with different spellings due to the fact that the Tunisian Dialect(TD) does not have an orthographic standard. For this we design crucial resources, namely sentiment lexicon and annotated corpus that we have used to investigate machine learning and deep learning models in order to identify the best sentiment analysis model for Tunisian Dialect.
