Researcher ยท Ph.D. Student
I'm JeongYun Lee, a Ph.D. student in the Department of Library and Information Science at Chung-Ang University in Seoul. My research interests lie at the intersection of AI and information organization, particularly in ontology and knowledge graphs. I enjoy exploring how AI can be applied in meaningful ways, and I also dabble in light development on the side. I love exchanging ideas and connecting with people across different fields, so feel free to reach out anytime!

Project Team
Team.Cayley is made up of students from Chung-Ang University in Library and Information Science and COSADAMA. You can see our work through the project links and GitHub. In the 'COVID-19: Our Memory' project, we archived social changes caused by the pandemic as data and donated the digital archive to the National Library of Korea in February 2022. In the 'Cultural Heritage Synapse' project, we consolidated scattered national treasure information from around 65 online and offline sources, proposed a standard for national treasure data, and used it for text analysis and a knowledge graph on Korean cultural heritage.
