Increasing the nanopublication recall with a BridgeDb Identifier Mapping Service

The volume of literature in the life sciences is continuously growing and keeping up with it is a problem. While review articles and databases help us by summarizing vast amounts of research, dissemination of core research outcomes is still mostly restricted to scholarly journal. Nanopublications have been proposed as a solution to capture scientific statements. This led to a 2010 proposal to serialize nanopubs in the Resource Description Framework (RDF) and in 2016 to an international network of nanopublication servers. However, RDF has a limitation that the Internationalized Resource Identifier (IRI) for resources does not have to be normalized and unique. To overcome this issue, the Open PHACTS project developed an Identifier Mapping Service and an approach called scientific lenses for mapping of equivalent IRIs. We here demonstrate the application of this approach to improve the recall of nanopublications from the international network.
