The CHAIN-REDS FP7 project, co-funded by the European Commission, has as a goal building a knowledge base of information, gathered both from dedicated surveys and other web and document sources, for largely more than half of the countries in the world, which it presents to visitors through geographic maps and tables. Earlier this month, its Knowledge Base and Semantic Search Engine for exploring the more than 30 million documents in its Open Access Document Repositories (OADR) and Data Repositories (DR) became available in a smartphone and tablet app, while the results of its Semantic Search Engine also now are ranked according to the January 2014 Ranking Web of Repositories. So, users conducting searches should see results in the order of the highest-ranked repositories.
The project has its roots in using semantic web technologies to correlate the data used to write scientific papers with the documents themselves whenever possible, says Prof. Roberto Barbera, of the Department of Physics and Astronomy at the University of Catania, as well as with applications that can be used to analyse the information. To drive to these ends, the CHAIN-REDS consortium semantically enriched its repositories and built its search engine on the related Linked Data. Users in search of information can get papers and data and, if applications are available, can be redirected to them on the project’s cloud infrastructure to reproduce and reanalyze the data.
“There is a huge effort in the scientific world about the reproducibility of science,” says Barbera.
