How much Knowledge is in Knowledge Graphs? A Knowledge Management Perspective

Managing and preserving knowledge in the best possible way has always been a key to the success for organisations, long before the term “Knowledge Graph” has entered the stage. However, the understanding of what exactly knowledge is, how it is represented and organised, and how knowledge is created often varies between different research communities. To this day, the scientific discipline of Knowledge Management is trying to capture the process of knowledge creation as converting implicit, i.e., tacit, knowledge into explicit knowledge. In this paper, we first summarize the idea of the Knowledge Management perspective on knowledge creation, and second discuss how Knowledge Graphs can contribute to solve the issue of making implicit knowledge explicit. We empirically survey the use of Knowledge Graphs in enterprise environments and discuss concrete use cases from a Knowledge Management viewpoint by selecting three concrete examples.
