Krzysztof Janowicz
The Why, What, and How of Geo-Information Observatories

"The geo-information universe has entered a phase of exponential growth. Yet, despite initial optimism it becomes clear that data does not speak for itself without a supporting infrastructure and theories that help to publish, retrieve, mine, synthesize, and reuse these data and translate them into insights. Focusing on data variety, this keynote will outline how old research visions can be addressed from a new perspective, illustrate new research challenges, highlight the role of semantics for data-intensive science, and propose how geo-information observatories can address some of these challenges."

Krzysztof Janowicz

Biography: Krzysztof Janowicz is an Assistant Professor for Geographic Information Science and Geoinformatics at the Geography Department of the University of California, Santa Barbara, USA. He is the program chair of the UCSB Cognitive Science program and a faculty research affiliate of the Center for Information Technology and Society. Krzysztof is one of the two editors-in-chief of the Semantic Web journal. He is running the STKO Lab which investigates the role of space and time for knowledge organization. His main research interests include the Semantic Web, Linked Data, ontologies, sensor webs, and cyber-infrastructures in general. Methodologically, his niche is the combination of theory-driven and data-driven approaches.
