A Data Quality Dashboard for (Security) Knowledge Graphs

Knowledge graphs play a crucial role in storing and reusing domain knowledge for data analytics. For example, knowledge graphs can be used to model security domain knowledge (such as technical standards) to support software architects in developing secure software systems. Assessing and assuring the quality of the data in these graphs is critical to enable trust in the use of this machine-readable domain knowledge, and to ensure high-quality results for downstream tasks that build on this knowledge. In this paper, we present a visual data quality dashboard, which allows domain experts to verify the quality of their domain knowledge graph along different dimensions. We demonstrate the use of the dashboard by means of a previously built security knowledge graph.
