Welcome to the KASTLE Lab

The Knowledge and Semantic Technologies (KASTLE) Laboratory was founded in 2022 at Wright State University by Dr. Cogan Shimizu.

KASTLE Lab’s mission is to

• develop fundamental advances in knowledge engineering, especially as they pertain to knowledge graphs and including the development of relevant cyberinfrastructure;
• explore the intersection between knowledge engineering, domain science, and machine/deep learning for the purpose of accelerating science and promoting data discovery and transdisciplinary research;
• understand the bridge between human-conceptualization and machine-encoding to better align and design AI systems; and
• advance the state of open curriculum in knowledge engineering and semantic technologies.
