Current research interests:

  • Natural Language Processing (NLP)
    • combining knowledge from diverse resources (e.g., BERT,  knowledge graph, ontology and lexicon) to enhance NLP, especially in low resource domains.
  • Large-scale social media analytics
    • building computational models of human traits (e.g., personality, needs, values, emotions, interests) and behavior (e.g., brand preferences, team collaboration  and substance use)
    • building computational tools to gain insight into our society (e.g., understand racism).
  • Human-AI interaction and societal Impact.
    • fair AI and ML systems.
    • explainable AI (XAI)
    • human-AI collaborative learning
  • Intelligent Interactive systems  
    • multimedia/multimodal dialogue systems
    • interactive text visualization
