Statistical and Machine Learning Methods

My first research line focuses on developing statistical and explainable machine learning methods for analyzing complex psychological data.

  • TextSEM: Integrating text data into structural equation modeling.1 [R package]
  • NeuralSEM: Incorporating neural network into Structural Equation Modeling.2
  • A Transformer-based framework for knowledge tracing with high predictive accuracy and interpretability.3 [preprint]
  • A guide on using neural network to analyze psychological dataset.4 [preprint]
  • Bass-Ackward Method on identifying the number of factors in factor analysis. 5 [paper] [online app]

Empathetic AI for Mental Health Support

My second research line leverages AI-driven techniques to enhance online mental health support, potentially reaching individuals who might otherwise lack access to timely assistance.

  • BLASH: An LLM-based writing assistant for peer-to-peer mental health support in online forums.6 [video demo]
  • MHKG: Improving mental health support response generation with event-based knowledge graph.7 [paper]
  • Leveraging LLMs for Suicide Intervention in Online Crisis Counseling.8

Text Mining on Social Bias and Sentiment

My third research line employs quantitative and computational methods to explore gender bias, particularly focusing on women’s experiences across digital platforms and their implications in broader social, cultural, and educational spheres.

  • Investigating gender bias in teaching evaluation via Large Language Models.9
  • Digital and historical exclusivity in feminine linguistics: from Nüshu to Xiaohongshu.10 [paper]
  • Structured Gender Bias: How is gender cognition changed and affected by digital communities in China? 11
  • Quantitative analysis on the communication of COVID-19 related social media rumors.12 [paper]
