  1. The CHAIN-REDS Knowledge Base Roberto Barbera – University of Catania and INFN - Italy (roberto.barbera@ct.infn.it)

  2. Introductoryconcepts and drivingconsiderations • The CHAIN-REDS Knowledge Base • Semanticsearch on CHAIN-REDS Linked Data • Summaryand conclusions Outline Rome – 24 January 2014

  3. Data Infrastructures Open Access Doc. Repos. Data Repos. The Scientific Method (worldwide, cross-domain, collaborationenabler) What do researchers do and how can e-I’s help them to improve it ? HTC/HPC Clusters Grids, Clouds Data preservation Semantic-web enrichment of linked data Rome – 24 January 2014

  4. The CHAIN-REDS Project(www.chain-project.eu) Started: 1 Dec 2012 Duration: 30 months Targetedregions: Africa, Arab Region, Latin America, China, India, and Far-East Asia Rome – 24 January 2014

  5. The CHAIN-REDS virtuous cycle Sustainability Access Inclusion Rome – 24 January 2014

  6. Largest e-Infrastructure related knowledge base. Information both from the survey and othersources for more than half of the countries of the world The CHAIN Knowledge Base(www.chain-project.eu/knowledge-base)

  7. Identifystandards to easilygather and accessboth Open Access DocumentRepositories (OADRs) and Data Repositories (DRs) • Build a demonstrator to easy visualise and accessOADRs and DRs (both geo-views and tab-views) • Correlate OADRs and DRs to create linked data and discover new knowledgethroughsemanticenrichment of metadata • Promote Data Infrastructurestandards and identify new OADRs and DRs from regionsaddressed by the project (Africa, Middle-East and GulfRegion, Latin America, China, India, Far-East Asia) • Populate the demonstrator with these new repositories, addthem to the semanticenrichmenttool, and set-up atleasttwo use-cases from differentdomains CHAIN-REDS program for Data Infrastructures Rome – 24 January 2014

  8. Open Access Document Repositories (OADRs) • 2,500 repos • >33 M docs Rome – 24 January 2014

  9. Data Repositories (DRs) •  600 repos • Lots of data ! Rome – 24 January 2014

  10. Data Repositories (DRs) Rome – 24 January 2014

  11. The CHAIN-REDS Semantic Search Engine Rome – 24 January 2014

  12. Multi-layered architecture Linked-data searchengine Semantic-web enrichment Harvester (running on grid/cloud) Harvester (running on grid/cloud) OAI-PMH OAI-PMH End-points Data Repos. OADRs Rome – 24 January 2014

  13. Linked data semantic search (www.chain-project.eu/semantic-search) More than 22 millionresources, almost 600 milliontriples Rome – 24 January 2014

  14. Linked data semantic search (www.chain-project.eu/semantic-search) Rome – 24 January 2014

  15. Linked data semantic search (www.chain-project.eu/linked-data) Preliminary ! New knowledge discovery!

  16. A step further: parallel search (“mashing up” semantic web repositories)

  17. Data Infrastructures are becoming an essential component of e-Infrastructures • Nextyears’ biggestchallengewill be to uniquely correlate scientificpapers with data used to writethem with applicationsused to analysethem so to be able to go across the knowledgepathboth ways • Semantic-web and linked-data technologies can play a major role in thiscontext and CHAIN-REDS aims to promotethesestandards in the targetedregions Summary and conclusions Rome – 24 January 2014
