Tb-SAC: Topic-based and Sentiment Classification for Saudi Dialects Tweets

ABSTRACT

Recently, sentiment analysis has received a lot of attention from researchers in text mining and data analysis. The studies have significantly expanded to include different languages from several sources that were employed to create a corpus to serve researchers in various shapes, sizes, and purposes. Locally, a lot of effort is spent on analyzing sentiment for Arabic texts, for both Modern Standard Arabic (MSA) and vernacular dialects. However, the researches concerned with creating a corpus based on the topic was relatively few. In this paper, we present Tb-SAC as extracted corpora from Twitter, especially from Saudi dialects. The corpus contains 4301 tweets, which labeled based on sentiments using a three-point scale positive, negative, and neutral. The corpus classify based on tweet topics into five main topics obtained from analyzing the gold set with 200 tweets. The topics were Personal, Religion, Coronavirus, Entertainment, Other (Education, Economy, Sport, Food, Health, Social Media, Distance Working, Technology, Comedy, and Politics). Then, we performed the annotation process manually, besides applying eleven different classification models and validate the corpus by cross-validation model.
