Visualisation of Complex Question Pools

In this paper, we discuss the conceptualisation and implementation of an interactive visualisation for complex question pools. In our case we require a way to organize and interact with a pool, including composition and selection of questions, e.g. for creating a test. We therefore use an ontology, which is a primary dimension of the questions, as a default view. Starting from a user-driven design process, we expand it with filter, search and data display functionality. After completion of the first implementation cycle, we evaluated the visualisation by conducting expert interviews and a formal requirement review. These showed that the visualisation solves some of the issues. To address the remainder, we propose a new version of the visualisation and ways to interact with the question pool.
