Presentation Transcript

  1. Research Information Linked Open Data Store euroCRIS members meeting, Bonn, may 2013

  2. Overview • Needs & Drivers • Information and data sources • Structured • Unstructerd • Architecture • Planned • Realised • Tools

  3. Project • Partners • Knowledge Management unit, EWI • IBM Belgium • Goals • Merge all sources into one open environment. • Apply entity resolution technique to remove data silo’s • Crawling and content analysis of full text elements • Build and test the proposed Pilot Architecture • Information integration form structured and unstructured data in one container • Build a number of visualisations of the information • Develop a roadmap towards the Operational Architecture • Timing: • 4 months starting from January 20113 • Cost • 124k euro

  4. Needs & drivers Better information: correct, actual , complete Open FRIS data for services and application devellopment Flemish government Open Data policy Maximum reuse of components Increase strategic intelligence Maximum reuse of data Policy monitoring: efficient & effective Connect data silo’s More information services Reduce system costs

  5. FRIS structured information

  6. FRIS Unstructured Data

  7. Information and Data sources • Structured Data • FRIS research portal database • Format: CERIF2006 database • Coverage: All universities 1 university college • 4 university OAR’s • Format: MODS records • Coverage: X publication records, X full tekst resources • VABB-SSH: publication monitoring data set on Social Sciences and Humanities • Format: MODS records • Coverage: All universities • Semantics and information model • Business Semantics Glossary • FRIS model: CERIF2006 • Semantics: Entitiy Classifications

  8. Information and Data sources • Unstructured Data • All textual information form the structured data • Project Abstracts • Publication Abstracts • Organisation Activity descriptions • Full text of Publication • Websites • Project • Researcher • Organisation

  9. Links andLocators • Access to unstructured data • Textual elements in CERIF model • Project Abstracts • Publication Abstracts • Organisation Activity descriptions • Websites • URI fields in CERIF entities • Links to fulltext • Resource links in MODS records

  10. Scope

  11. Somenumbers • CERIF records: • Person:22.006 (FRIS) +1.454.208 (OAI without resolution) • Project:24.634 (FRIS) • Organisation:1.398 (OAI) + 2.022 (FRIS) • Publications: 3.596(FRIS) • MODS records • OAR’s:598.035 (OAI) + VABB database • Publication Full text :45.294 (OAI)

  12. PlannedArchitecture Identifiers & EntityResolution Content Analysis Concept Extraction Visualisation Triple Store Structured Data input Operational Store Semantic control

  13. RELOD Structured Data Architecture

  17. Somenumbers • Entities • Projecten: 24.634 (FRIS) • Personen: 22.006 (FRIS) +1.454.208 (OAI zonderresolutie!)) • Publicaties: 598.035 (OAI) + 3.596 (FRIS) • With full text: 45.294 (OAI) • OrgUnit: 1.398 (OAI) + 2.022 (FRIS) • Recognised author affiliation from full text: 55662 • Triple Store • Triples FRIS+OAI : 57M • Triples text mining (author recognition + lemmas) : 144M • --> Still without inference (no inference deduce triples)

  18. Analyse - Visualisatie

  19. Visualisations • Two test visualisations build sofar: • Word cloud for person • http://ewisclod3.vlaanderen.be/words/ • Persons related to Concepts • http://ewisclod3.vlaanderen.be/persons/ • New visualisations will be build on well defined use cases • Tuning the Content analytics to the case • Supervised learning for specific domains • Give an contextual overview of research from the last 10 years on social security issues in Belgium • Annual report on research in the domain of renewable energy

  20. Entityresolution • A few tools tested • Silk Link Discovery Framework • used to map authors from the OAR harvest onto Persons form the CERIF sources. • Experimented with • manual construction of matching ruls via de Silk workbench • Active learning combined with the Silk generic algoritms • Several metrics on the tekst dimensions: Levenstein, tf-idf, Jaro, Jacard in combination with numerical and temporal dimensions • Results still have to be validated in detail. • Tests with OKKAM are planned

  21. Architecture Roadmap Elements (optional) Replace D2R with standard: R2RML Full-CERIF automatic D2R template generation Support incremental CERIF/RDF loading Integration of Data Governance Center via he API Complete modelling of CERIF and Semantics in Data Governance Center Full-CERIF automatic ontology template generation manueel geautomatiseerd
