Abstract

Online forums have become crucial platforms for making decisions and expressing emotions [3]. The purpose of the study is to find out how users’ decisions during online debates are influenced by their emotions, particularly happiness, anger, sadness, and enthusiasm [24]. While many studies focus on examining relationships between emotions and specific behaviors, this study aims to investigate if emotions cause those behaviors [22]. In order to accomplish this goal, psychological understanding of how people respond to particular circumstances is integrated with contemporary computational techniques [11]. Using textual data collected from online discussion forums, a deep learning transformer network will identify emotions [7]. After that, emotional expressions will be examined in terms of their dynamics and impact on user reactions. Reply rates, agreement, and interaction are all decisions made by users. The study’s integration of deep learning techniques with a causality analysis model to determine whether there is a relationship between certain user actions and emotions is one of its main achievements [28]. The models Logistic Regression, SVM, Random Forest, LSTM, and BERT will be evaluated according to their F1-score, accuracy, precision, and recall [20]. The findings demonstrate that in terms of comprehending emotional context and forecasting user behavior, transformer-based models outperform conventional techniques [17]. More significantly, the results imply that decisions made in online settings are heavily influenced by emotions [16]. All things considered, this study offers a coherent paradigm that links psychology and computer science, providing greater understanding of human behavior in online communities. Additionally, it aids in the creation of online systems that are better able to comprehend and react to human emotions.
