Knowledge Technology Research Group

Knowledge Technology Research Group

The Knowledge Technology Research Group is the youngest part of the human-computer interface research at the Faculty of Information Technology. Despite that, it has a long track record of research and development results in a wide range of areas related to knowledge extraction, representation, and management, as well as advanced machine learning and big data processing. The team has participated in many international and national projects funded by various grant agencies or relevant industries.
