  3. 3. Towards a holistic visualization management for knowledge graphs The Company 3 intelligent views gmbh is a leading vendor of semantic technology and develops k-infinity, the database that works the way people think. We offer development and knowledge engineering services based around k-infinity in order to assist our customer in getting the most out of their data… …working with networked information …connecting structured and unstructured information …putting business users in charge of data modelling and analysis …integrating and hamonising data – structured and unstructured …visualising information intelligent views was spun off 1997 from Fraunhofer Research
  4. 4. Towards a holistic visualization management for knowledge graphs Motivation 4 State of visualizations for knowledge graphs: Linked Data visualizations mostly graph visualizations (Dadzie & Rowe 2011) Multi-faceted graph visualization (Hadlak et al. 2015) Evaluating to the visual information seeking mantra (Shneiderman 1996): Generating an overview of the underlying data Support for filtering out less important data in order to focus on selected ROIs Support for visualizing the details in ROIs Other tasks for knowledge graph visualization: Handling multi-dimensional data, hierarchical data, network data Identifying relationships within data
  5. 5. Towards a holistic visualization management for knowledge graphs Approach 5 Possibility for knowledge engineers to create and align views while modeling Mapping these views to frontend templates created by designers Benefits Create visualizations according to the visual information seeking mantra Keep separations of concerns (knowledge engineer/designer) Quick changes to views possible
