Frequently asked questions
Short answers about Pascal Sun's research, publications and projects, and how to get in touch.
Who is Pascal Sun?
Pascal Sun is a Ph.D. candidate in Computer Science at The University of Western Australia in Perth, Australia, studying since 2022. He worked as a full-stack developer at MetroCount (2019 to 2021) and Artrya (2021 to 2023). He is passionate about bringing research into reality, and is working on making this happen in Western Australia.
What does Pascal Sun research?
Knowledge graphs and natural language processing. His research interests include knowledge graph construction, knowledge graph embedding, knowledge graph enhanced retrieval augmented generation, knowledge graph reasoning, multimodal large language models, and knowledge discovery from unstructured data.
What has Pascal Sun published?
His papers include Docs2KG and TimelineKGQA (WWW 2025 Companion), DocSpiral (ACL 2025), DAG-Think-Twice (PAKDD 2025), OpenOmni (EMNLP 2024 Demo), Are Graph Embeddings the Panacea? (PAKDD 2024) and Graph Embeddings for Non-IID Data Feature Representation Learning (AusDM 2022). OpenOmni won the Best Demo Paper Award at EMNLP 2024, and the AusDM 2022 paper won the Best Research Paper Award. The full list, with links to each paper, is on the Publications page.
What projects has Pascal Sun worked on?
Research projects: ChatGEO, a spatial semantic document retrieval system (2024 to now), ACYWA, the Australian Child and Youth Wellbeing Atlas (2024 to now), and GAMES, a system for evaluating the rehabilitation of mining sites and a finalist for the 31st INCITE Awards (2021 to 2022). Commercial projects: Salix, the FDA approved AI platform for coronary artery disease at Artrya, and ATLYST and RoadPod VM for traffic data at MetroCount. Personal project: Map.FindPerth.com, which shows WA suburbs through crime, school and Census data. Details are on the Projects page.
How do Pascal Sun's projects relate to his research?
The research projects put his research interests to work. ChatGEO uses generative AI and NLP to make retrieving spatial documents more efficient and the results more trustworthy, and ACYWA uses maps so researchers and government can see the wellbeing of children and young people across Australia. The commercial projects are the products he helped build and commercialise as a full-stack developer at Artrya and MetroCount.
Does Pascal Sun teach or run bootcamps?
Yes. He created a collection of bootcamps, guides and resources for the UWA NLP-TLP research group, from development environment setup to advanced AI engineering skills: a Dev Setup guide, GPU Resources, an AI Engineer Bootcamp and a Research Skill Bootcamp. They are under Tutorial on this site.
