Prof. In-Young Ko leads the Web Engineering Lab at KAIST. The lab focuses on software engineering for web-based systems, including service computing, web applications, and dynamic/adaptive software. Key areas of research include task-oriented service provision, service composition, semantic web applications, and end-user software engineering. The lab has several PhD and MS students working on projects related to service discovery, composition in IoT/edge environments, and knowledge-based software reuse. The goal is to develop software that can effectively utilize web resources and adapt to changing environments.
