The aim of the workshop is to bring together professionals and practitioners from academic, business, and government communities from all over the world interested in exploring how diversity affects data and knowledge, and discuss applications, supporting methodologies and tools. The event is the follow-up of the first three editions, held in Bangalore and Trento, in the context of the ITPAR project between Italy and India. The initiative is now attracting attention from a growing number of institutions world-wide. The workshop is organized into sessions, each of them addressing one specific topic. Sessions will be interactive to discuss and agree about joint activities to be done together in the future, and possible joint projects.We organized our third KiDF workshop with a motto “Unity and Diversity”. Professors from various leading universities in India, China, Mongolia and Trento participated in the event.
