My research focuses on better understanding the latent discourse aspects in large corpora of natural language text, and using this understanding to build computational models that can improve human communication process. My research interests lie in the areas of discourse processing, social NLP, learning analytics and software engineering. Some of my recent research projects explores;
Regardless of the discipline, I am passionate about everything in TEXT, DISCOURSE, LANGUAGE, COGNITIVE PSYCHOLOGY & MIND :)
- Using linguistic fingerprints to combat cyberbullying
- Advancing the detection of cyberbullying through role modeling
- Modeling emotion-cause relation in mental health language data
- Modeling language-related to mental health using social media data
- Multi-class emotion modeling from social media data
- Automated glossary generation for effective information extraction from COVID-19 scientific articles
- Assessing Software Documentation quality
- Impact of teachers’ academic discourse in lecture videos for students’ video engagement in MOOCs
- Modeling coginitive engagement and measuring new knowledge construction in online teacher PD MOOCs
- Detecting 'confusion' state of discussion forums in MOOCs
