RelFinder

Are you interested in how things are related with each other? The RelFinder helps to get an overview: It extracts and visualizes relationships between objects in RDF data and makes these relationships interactively explorable.

Please find more information about the RelFinder at: http://relfinder.visualdataweb.org


gFacet

Complex semantic querying made easy! gFacet supports faceted exploration of RDF data by representing facets as nodes in a graph visualization. The facets can be interactively added and removed in order to produce individual search interfaces.

Please find more information about gFacet at: http://gfacet.visualdataweb.org


SemLens

Do you want to analyse trends and correlations in RDF data? SemLens provides a visual interface that combines scatter plots and semantic lenses. The scatter plots offers a global visualization that can be locally explored with the semantic lenses.

Please find more information about SemLens at: http://semlens.visualdataweb.org


tFacet

tFacet applies known interaction concepts to allow hierarchical faceted exploration of RDF data. The aim is to facilitate ordinary users to formulate semantically unambiguous queries so as to support the fast and precise access to information.

Please find more information about tFacet at: http://tfacet.visualdataweb.org


ChainGraph

Common graph visualizations tend to produce edge crossings and overlaps when used to display resource collections that are highly interrelated via shared properties. With ChainGraph we present a new approach that visualizes resources and their shared properties in chains to prevent dense graphs and to better support the exploration of relationships.

InteractiveExtractor

Examining all relevant information can be very demanding and time consuming. Thus, methods and tools are needed that assist in the integration of this heterogeneous and distributed information. The InteractiveExtractor is such a tool that aims at visually supporting the integration of distributed information into semantic structures.
