Visual representations for Linked Open Data
to observe multiple aspectsof the data while controlling
and coordinating its views
to additionally reveal the links between the data
Visual workflow for Linked Open Data
Visual workflow dynamic
Visual representation static
A visual workflow for resources represented
as Linked Open Datafor exploitation, discovery and analysis
of the Web of Data for scholarsusing information exploration techniques
Visual Workflow
Visual Workflow
Information Exploration:
Exploratory Data Analysis
The scholar gets familiar with the dataset
no explicit assumption regarding the dataset
the dataset itself reveals its underlying model and the relationships between its resources

Visual Workflow
Coordinated view
Most detailed resourcescannot be further decomposed
a certain resource or the links between two resources
Coordinates the narrowing and the broadening view

Visual Workflow
Information Exploration:
Exploratory Search
The scholar is familiar with the dataset
Scholars explore the dataset on their ownfind novel relations between resources
Views are not limited to the data of the dataset but relevant links to resources of other datasets are also revealed and visualized

Survey Results: Explorability
Survey Results: Complexity
User test results: Narrowing View
User test results: Broadening View
Conclusions
Novel visual workflow for exploring resources in the Web of Data
User interfaces based on graph visualizations offer unique, multifaceted experience
when combined with techniques for information explorationand enhanced with optimized search in Linked Data.
enables scholars to view and navigate through combined aspects of research data
to come up spontaneously with observations whose reasoning can be directly investigated
