Investigating the Effect of Emoji in Opinion Classification of Uzbek Movie Review Comments
This work addresses opinion mining for Uzbek social media users, but it is incremental as it applies existing methods to a new language and dataset.
The study examined how emoji-based features affect opinion classification in Uzbek movie review comments from YouTube, finding that these features improved classification performance with specific algorithms.
Opinion mining on social media posts has become more and more popular. Users often express their opinion on a topic not only with words but they also use image symbols such as emoticons and emoji. In this paper, we investigate the effect of emoji-based features in opinion classification of Uzbek texts, and more specifically movie review comments from YouTube. Several classification algorithms are tested, and feature ranking is performed to evaluate the discriminative ability of the emoji-based features.
