  1. The Rhizomik InitiativePlaying with UN-FAO Data Roberto García HCI & Data Integration Research Group Universitat de Lleida, Spain

  2. Table of Contents • Consolidation • Semantic data consolidation and disambiguation • Rhizomer • Linked Data publishing and interaction

  3. Consolidation • Collaboration with Sindice group at DERI Galway • Sindice: a Semantic Web index and search engine • Consolidate semantic data: • Integration, disambiguation,… • Make Sindice return entities instead of documents

  4. Consolidation • Demo scenario: • DBLP same URI for different authors if same name-surname • Approach: each author his/her co-authorship net

  5. Consolidation Approach

  6. Co-authorship Network for Tom Anderson

  7. Mine, and another Roberto García…

  8. Consolidation Questions, comments,… …boring?

  9. Rhizomer • Linked Data publishing and interaction platform • Rhizomer Server: • Java, REST API • Stores: Jena, Virtuoso,… • DESCRIBE (CBD+labels) RhizomerClient edit search delete new GET PUT POST DEL RhizomerServer MetadataStore

  10. Experiment • Start with AGRIS RDF data (824 articles file) • Point URIs to where Rhizomer is installed • E.g.: http://rhizomik.net/agris/... • URIs end with a slash • Add labels for usability:  • CONSTRUCT  { ?r <http://www.w3.org/2000/01/rdf-schema#label> ?l }WHERE  { ?r a ?t.    FILTER( ?t=<http://purl.org/ontology/bibo/Article> ||                 ?t=<http://xmlns.com/foaf/0.1/Person> ||                 ?t=<http://xmlns.com/foaf/0.1/Agent> ||                 ?t=<http://purl.org/ontology/bibo/Journal> )    OPTIONAL      { ?r <http://purl.org/dc/elements/1.1/title> ?l }    OPTIONAL      { ?r <http://xmlns.com/foaf/0.1/name> ?l }  }

  11. Experiment • dc:subject points to AGROVOC resources (not literals) • Load ontologies/schemas (FOAF, BIBO, DC, RDF, RDFS,…) • Load AGROVOC SKOS • …

  12. Rhizomer Client • AJAX • Browsing: • RDF/XML ─XSLT HTML+RDFa • Editing: • RDF/XML ─XSLTFORM ─Javascript RDF • Autocomplete • from actual data and ontologies

  13. Rhizomer Client • Not just show data, make it more usable: • Information Architecture Componentes: • Navigation Menus  • Automatic from data and ontologies • Facets • Automatic, properties and actual values • Interaction Services framework • Timeline, Map, Player, Graph, Plot,…

  14. Demo http://rhizomik.net/agris/

  15. Conclusions • AGRIS data almost LOD: • Links to other LOD datasets • DBPedia, CIA Factbook,…

  16. Conclusions • Explicit licensing terms • Motivation: make AGRIS URIs for publications the HUB for LOD about those publications • …URI marketing
