Table of Contents• Consolidation

– Semantic data consolidation and disambiguation

• Rhizomer– Linked Data publishing and interaction

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

Consolidation• Demo scenario:

• DBLP same URI for different authors if same name-surname– Approach: each author his/her co-authorship net

Consolidation Approach

Co-authorship Network for Tom Anderson

Mine, and another Roberto García…

Rhizomer• Linked Data publishing

and interaction platform

• Rhizomer Server:– Java, REST API

– Stores: Jena, Virtuoso,…

– DESCRIBE (CBD+labels)

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 }  }

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

RDFS,…)• Load AGROVOC SKOS• …

Rhizomer Client• AJAX

• Browsing:– RDF/XML ─XSLT HTML+RDFa

• Editing:– RDF/XML ─XSLT FORM ─Javascript RDF

– Autocomplete • from actual data and ontologies

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,…

Conclusions• AGRIS data almost LOD:

– Links to other LOD datasets• DBPedia, CIA Factbook,…

Conclusions• Explicit licensing terms

• Motivation: make AGRIS URIs for publications the HUB for LOD about those publications– …URI marketing
