Founded in 2014 and formally established in 2017, the Knowledge and Uncertainty Research Laboratory examines the role of knowledge and of its absence in the theory and application of information technology. Our main theoretical tools are fuzzy mathematics and the semantic web, while fields such as information visualization, artificial intelligence, information retrieval, adaptation to the user, cultural informatics, social networks and smart cities also have an important role in the teams research. The laboratory is unconventional, in the sense that it deviates from the typical notion of research laboratory and follows a more open approach.
