(Visual) Exploratory Search

Adaptive search interfaces which allow the real-time navigation through multimodal continuously updating linked data graphs are what is needed to make the huge amount of Big Data to be consumable by humans. IDLab has expertise in designing these interfaces but also the technologies under the hood such as search engines, semantic similarity measures, path finding techniques and recommendation systems which present the most relevant information the the end-user or to automatically generate relevant stories based on the data.
