Sarcasm Detection in Twitter Data
Posting sarcastic messages on social media like Twitter, Facebook, WhatsApp, etc., became a new trend to avoid direct negativity. Detecting this indirect negativity in the social media text has become an important task as they influence every business organization. In the presence of sarcasm, detection of actual sentiment on these texts has become the most challenging task. An automated system is required that will be capable of identifying actual sentiment of a given text in the presence of sarcasm. In this chapter, we proposed an automated system for sarcasm detection in social media text using six algorithms that are capable to analyze the various types of sarcasm occurs in Twitter data. These algorithms use lexical, pragmatic, hyperbolic and contextual features of text to identify sarcasm. In the contextual feature, we mainly focus on situation, topical, temporal, and historical context of the text. The experimental results of proposed approach were compared with state-of-the-art techniques.
