Semantic Technologies

  • Web 1.0: hyperlinked documents (World Wide Web)
  • Web 2.0: interactive applications, the Social Web
  • Web 3.0: interlinked data (Global Giant Graph)

Is this something new?

  • It was all envisioned by Sir Tim Berners-Lee 25 years ago
  • Standardized by W3C: both HTML and sem web standards (RDF, RDFS, OWL, SPARQL…)
  • Great flurry of sem tech activity in the last 15 years
  • Buzzwords: Big Data, Semantic Analytics, Concept Extraction, Sentiment Analysis…

Ontotext in Europeana

Ontotext works on fundamental backend technologies important for KPIs OntotextContributesToEuropeana.png

Europeana OAI and SPARQL

Ontotext creates OAI PMH server for Europeana

  • So we or others can download objects in bulk

Ontotext hosts the Europeana semantic data (EDM) in OWLIM

SPARQL 1.1 Queries

Eg Polish Periodicals by library and decade
http://europeana-test.ontotext.com/sparql

select 
  ?date 
  (sum(?n1) as ?Uniwersytetu_Warszawskiego)
  (sum(?n2) as ?Politechniki_Lubelskiej)
  (sum(?n3) as ?Baltycka)
{
  ?x dc:type 'periodical'@en.
  ?x ore:proxyIn/edm:dataProvider ?dataProvider.
  ?x dc:date ?date2.
  bind (xsd:integer(concat(substr(?date2,1,3),'0')) as ?date)
  bind (if(?dataProvider='e-biblioteka Uniwersytetu Warszawskiego',1,0) as ?n1)
  bind (if(?dataProvider='Biblioteka Cyfrowa Politechniki Lubelskiej',1,0) as ?n2)
  bind (if(?dataProvider='Bałtycka Biblioteka Cyfrowa',1,0) as ?n3)
} group by ?date order by ?date

SPARQL Analytics

Eg Polish Periodicals by library & decade (you can jsfiddle with it)
