The Knowledge Graph Radar is an attempt to keep track of interesting people, projects, applications and so forth related to the knowledge graph space.

When I say "related to" I am going broad rather than narrow. That is, I will probably include things that are only tangentially related to knowledge graphs but that could be of interest within the context of the development of Contextualise, the (personal and collaborative) knowledge management application that I am developing. Having said that, I will try to stay on topic as much as possible :)
