Bubble Navigator

The Bubble Navigator is a tool for visual navigation of semi-structured or semantic web data. Its main strength is the ability to visualize vast amount of data and to provide full-text search in the real-time.



LODmilla is a DBpedia visualization service. LODmilla aims at visualizing associations in LOD graphs with special linked data functions such as

  • searching and exploring the neighborhood of a resource node,
  • saving and sharing graph views,
  • doing minor edits on triples,
  • etc.




The ExConQuer Framework consists of two tools:
  • The Query Builder Tool: Works on top of DBpedia (or other SPARQL endpoints) and enables users to construct a SPARQL query without requiring any knowledge of SPARQL or the datasets' underlying schema. Users are then able to download the data they require in a number of different formats. 


LodLiveproject provides a demonstration of the use of Linked Data standards (RDF, SPARQL) to browse RDF resources. The application aims to spread linked data principles using a simple and friendly interface with reusable techniques.


Faceted Wikipedia Search

Faceted Wikipedia Search allowed users to ask complex queries, like “Which Rivers flow into the Rhine and are longer than 50 kilometers?” or “Which Skyscrapers in China have more than 50 floors and have been constructed before the year 2000?” against Wikipedia. The answers to these queries are not generated using key word matching as the answers of search engines like Google or Yahoo, but are generated based on structured information that has been extracted from many different Wikipedia articles.
