Sarcasm, a common form of communication found in online platforms, serves as a way to express feelings or opinions in a subtle, often humorous, and sometimes derisive manner. While it is easy to detect sarcasm in face-to-face interactions through facial expressions and tone of voice, identifying sarcasm in written text poses a significant challenge.

Geeta Abakash Sahu and Manoj Hudnurkar from the Symbiosis International University in Pune, India, have introduced a sophisticated model for detecting sarcasm in digital conversations. The model consists of four key phases, starting with text pre-processing to eliminate irrelevant words and break down the text into smaller units. The team then employs optimal feature selection techniques to prioritize the most relevant features for sarcasm detection.

The Role of Feature Extraction and Classification Algorithms

The research team utilizes various feature selection methods, such as information gain, chi-square, mutual information, and symmetrical uncertainty, to extract features indicative of sarcasm from the pre-processed data. Subsequently, an ensemble classifier comprising Neural Networks, Random Forests, Support Vector Machines, and a Deep Convolutional Neural Network is employed for sarcasm detection.

To enhance the performance of the Deep Convolutional Neural Network, the team introduces a novel optimization algorithm called Clan Updated Grey Wolf Optimization. The results of the study demonstrate that the proposed approach outperforms existing methods in terms of specificity, false negative rates, and correlation values, indicating its effectiveness in accurately identifying sarcastic remarks in online conversations.

Implications for Natural Language Processing and Sentiment Analysis

Beyond its immediate application in sarcasm detection, the research holds significant promise for enhancing sentiment analysis algorithms, social media monitoring tools, and automated customer service systems. By improving the understanding of nuanced communication cues in online interactions, the model developed by Sahu and Hudnurkar contributes to more effective and accurate analysis of digital conversations.
