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.

Dashboard is a prominent artefact that users interact with when it comes to learning analytics. What is a learning analytics dashboard ? Who is it for? What is the key to effective adoption of learning analytics dashboard? Listen to Martin Hlosta and Fabio Campos sharing their experience in supporting the use of learning analytics dashboard on a large scale.
The success of learning analytics rests on how students understand and use them. We asked pre-service teachers how they would see LA supporting their studies in higher education. Learn more about the four roles that we identified from students’ conversations!
