Challenges of source selection in the WoD

Tobias Grubenmann, Abraham Bernstein, Dmitrii Moor, Sven Seuken
In this paper, we analyze the usefulness of cardinality approximation for source selection.  ...  In many cases, however, data may be available from multiple sources resulting in a combinatorially growing number of alternative allocations of subqueries to sources.  ...  Acknowledgments This work was partially supported by the Swiss National Science Foundation under grant #153598.  ...

Exploration and Visualization in the Web of Big Linked Data: A Survey of the State of the Art [article]

Nikos Bikakis, Timos Sellis
2016 arXiv   pre-print
Data exploration and visualization systems are of great importance in the Big Data era.  ...  Finally, we survey the systems developed by Semantic Web community in the context of the Web of Linked Data, and discuss to which extent these satisfy the contemporary requirements.  ...  The tool takes as input a SPARQL endpoint and generates a visual (graph-based) summary of the WoD source, accompanied by statistical and structural information of the source.  ...

The impact of animal platforms on polar ocean observation

M.A. Fedak
2013 Deep-sea research. Part II, Topical studies in oceanography  
The contribution of animal-borne CTDs to the WOD is increasing rapidly and is likely also to have a major impact, especially in higher latitudes.  ...  The magnitude of the contribution can be appreciated by querying the World Ocean Data Base (WOD).  ...  Note that data from other sources, such as Argo Floats, can also be seen and compared by selecting other sensor types in the list.  ...
