SNIK Graph—Visualizing Knowledge about Management of Hospital Information Systems

Medical and health informatics integrates knowledge of business information systems, computer science and medicine.As a comparatively young research discipline, it lacks a uniform terminology, especially for describing health information systems and their management.Several textbooks provide different perspectives of the discipline but the linear struture inherent in a book does not intuitively convey the highly connected nature of the concepts of the domain.SNIK (Höffner et al., 2017) is a semantic network of information management in hospitals, which uses Semantic Web standards like RDF and OWL to model and publish the knowledge of three textbooks (Ammenwerth et al., 2014;Heinrich et al., 2014;Winter et al., 2011), the IT4IT (The Open Group, 2017) standard and an interview with a hospital CIO.Each of those sources is modelled according to the SNIK meta model, which classifies each resource as being either a role, function or entity type, see Figure 1.
