Transcript

  • 1. WESO Research Group Jose Emilio Labra Gayo WESO = WEb Semantics Oviedo) www.weso.es
  • 2. About WESOCreated in 2004Application of Semantic Web technlogies4 associate professors 6 students (Phd + Master)Address: University of Oviedo Dept. Computer Science Oviedo, Spain
  • 3. ¿Where is Oviedo?
  • 4. Some relevant projects BOPA BCN MOLDEAS ACOTA ORBITA WebIndex ROCAS
  • 5. BOPAOfficial Gazette Principality of Asturias - 2004 Convert daily published laws in Asturias to RDF Semantic search engine Using spreading activation to expand search query Software: OntoSpread Challenges detected: Visualization tool Ontology development
  • 6. BCNNational Library of Congress, Chile History of the Law Linked Open Data 300.000 norms and their relationships First stage: Only metadata Title, important dates, types, relationships We exclude body text (articles, chapters, etc.) Entity reconciliation Match strings to URIs Entities: Person names, Organizations (political parties, Location names Charges .... Semantic search engine In development
  • 7. MOLDEASCompany: EuroAlert (Gateway) Public procurement notices Catalog of product schema clasifications (1842053 triples) http://thedatahub.org/dataset/pscs-catalogue Common Procurement vocabulary (803311 triples) http://thedatahub.org/dataset/cpv-2008 Multilingual Linked data 23 EU languages MOLDEAS = Methods On Linked Data for E-procurement Applying Semantics
  • 8. ACOTATreelogic (technological research product)Tag suggestion + Ontology feedbackLibrary to suggest tags based on ontology conceptsOntology feedback in development
  • 9. ORBITACompany: TreelogicVisualization of linked dataEntity reconciliationBased on previous work: LODViz
  • 10. WebIndexPartner: Web FoundationMeasure the impact of the web in the world61 countries, 83 indicatorsOur work: Convert Statistical data to linked data Input: Excel spreadsheets Output: Linked data (RDF Data cube)
  • 11. ROCASGOAL: Algorithms to query large semantic dataChallenge: Semantic search + inference + cloudIntuition: SPARQL queries + backward reasoningIn development MapReduce? ROCAS = Reasoning On the Cloud by Applying Semantics
  • 12. Personal backgroundOn a sabbatical (Sep 2012-Feb 2013)Research Interests: Linked Open Data Multilingual Linked Open Data RDF + SPARQL + Inference engines Backward reasoning (Prolog-like) Cloud Computing (MapReduce) MapReduce, Parallel algorithms over graphs Scala - Functional programming Phd Thesis: Monads, generic programming, modularity
  • 13. Research Interests Linked Data Semantic web stack RDF + SPARQL + Inference Multilinguism NLP + Semantic Search ScalaFunctional + Generic Programming MapReduce Distributed Computing
