Abstract
The Australian Persistent Identifier (PID) graph (also known as National PID Graph) connects Australian research to funders, research activities, and research outcomes using persistent identifiers. Connections between ORCID, ROR, DOI, RAID, and other PIDs provide a valuable source of information about the digital footprint of research and the collaboration network of Australian researchers. In this presentation, we offer insights about the key nodes in this network, such as the most connected funded projects in Australia, and the researchers who have the most international collaborations. We demonstrate how well-established graph algorithms, such as centrality, can offer insights about Australian research, revealing hub nodes and bridge nodes that provide critical links between communities. Additionally, we report on the state of the missing links in the Australian PID graph, including missing ORCID links from publications and ARC/NHMRC grants, as well as missing ROR records for Australian organisations that are collaborators in this network.
