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. 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. 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

7. Towards a holistic visualization management for knowledge graphs
Approach
7
Possibility for knowledge engineers to create and align views while modeling
Use the modeling tool and environment
Use semantic technologies
Mapping these views to frontend templates created by designers
Use the techniques designers are used to

Lessons learned
21
Important, but difficult to maintain separation of concerns
Importance of preview functionality
Lifecycle overlapping between creating frontend templates and configuring views
Maintaining a simple, clean view configuration model is challenging
