Transcript of "eResearch Services for 20th Century Paint Conservation Suleiman ..."

  1. 1. Suleiman Odat s.odat@uq.edu.au
  2. 2.  Introduction – 20th Century in Paint Project  Online portal (www.20thcpaint.org) o Architecture o Data Upload o Linked Data o Search Interface  What are ontologies, and why do we need them  The Ontology of Paintings and PReservation of Art (OPPRA) o The Semantic Model o Classes, Properties and Reasoning o Reusing upper-level ontologies o Example queries o Visualizing answers  Future Work  Conclusions
  3. 3.  Funded by ARC 2008 – 2011  Collaborative project - 10 cultural institutions, 2 universities across four continents: Uni of Melb / Uni of Qld / Getty / ArtLab / Tate / NSW Art Gal / QLD Art Gal / Tasmanian Museum / Malaysia Art Gal / SAMEO SPAFA  Develop a shared knowledge-base that answers questions relating to painting conservation ◦ Art history (Ian Fairweather, Sidney Nolan, Rover Thomas) ◦ Artistic techniques – which paints, thinners, whiteners were used ◦ Provenance of painting ◦ Materials characterisation – physical/chemical composition, microstructure ◦ Paint stability and deterioration mechanisms  Provide tools for data capture, upload, analysis  Support online collaboration – Wiki to share expertise  Understand issues that effect paint handling, performance and permanence
  4. 4. QAG AGNSW CCMC Web Interface Apache Tomcat Jackrabbit Repository MySQL Database Microscopy Images Artists Ontology Paint Provenance Reference Libraries Characterisation Data Publications User Ids, Passwords, Contact Details, Access Rights Public Secure Port Databases ... Wiki Ontology
  5. 5.  Gillian Osmond – investigating effects of temp, humidity & light on formation of zinc oxide crystals  China white – used to lighten acrylic paints ◦ Reacts with organic base of acrylic paint Zinc Soap aggregation has caused a bubbling and cracking in the paint SEM shows strong correlation between zinc concentration and aggregates
  6. 6. Need to Integrate:  Databases – Artists, Artworks/Images, Provenance, Paint databases, Reference Libraries, Characterisation data, Condition assessments  Publications – text mining  Different formats – images, video, text, ....  Different metadata/terminologies Want to answer complex queries:  “What is the best way to treat zinc oxide soap crystals in oil paintings by Ian Fairweather?” Need Semantic Web Technologies –  RDF – Resource Description Framework  OWL – Ontology Web Language  Semantic annotation tools – tag publications/images with ontology-based terms
  7. 7.  Metadata/Annotations in RDF o Community knowledge and scholarly mark-up o Machine processable tags/metadata o RDF graphs -> OAI-ORE compound objects  Indexing, Search Services o Full text indexing, keyword search  OWL Ontologies o Collection organization and discovery o Database integration and inferencing  SWRL Inferencing rules – 2D feature, 3D object recognition, relationship discovery
  8. 8.  In the context of knowledge sharing and reuse  "Ontology” - term is borrowed from philosophy to describe the concepts and relationships about certain knowledge domains  Defined as a set of classes/sub-classes, properties/sub-properties and relationships  Represented as RDF/OWL  Can be processed/understood by computers
  9. 9.  Create a set of sub-ontologies (classes/properties) that describe our sub-domains (use Art Architecture Thesaurus (AAT), CAMEO, INCCA, IRUG, etc) o Paintings o Provenance o Materials o Conservation  Connect the sub-ontologies via an upper ontology  Then use logical reasoning applications to connect these facts and infer new information o FACT++ / Pallet o Ian Fairweather -> had_art_teacher -> Henry Tonks o Henry Tonks -> taught_technique -> tonking o IanFairweather -> used_technique -> tonking (using absorbent material to soak excess oil from canvas)
  10. 10.  Shareable, re-usable, accessible via Web  Defines hierarchies of classes and properties describing: o Upper Ontology – Thing, Agent, Concept, PhysicalObject, TemporalEntity, SpatialEntity o Paintings and artists o Painting materials  Chemical composition  Structural composition – characterisation o Provenance (owner, previous history) o Painting techniques o Degradation/deterioration mechanisms  Cracking, Peeling o Conservation approaches and materials  Cleaning

  13. 13. undergoes generates hasSubclass
  14. 14. usesMaterial hasSubclass
  15. 15.  Analyse publications and databases  Map existing and newly generated data to our ontologies  Generate instance data that complies with our ontologies  Store in RDF triple store  Provide SPARQL querying interface  Provide reasoning tools (Pellet/FACT++)
  16. 16.  Ontology-based SPARQL querying interface  “What solvents will remove surface varnish from the painting “Epiphany”? ◦ QAG - It is painted by Ian Fairweather in 1962 ◦ NGA - Ian Fairweather used dulux acrylic coated with shellac ◦ CAMEO - The best solvent for removing shellac is methyl ethyl ketone  Answer = “methyl ethyl ketone”  Annotation/Social tagging – community/expert knowledge – of images and text  Provenance capture – semi-automated capture of conservation events
  17. 17.  De Mayern and MOLAR Programs in Netherlands  Molecular Studies in Conservation and Technical Studies in Art History  RKD (Netherlands Institute for Art History) ◦ Online Databases  Winsor & Newton Recipes Database ◦ 19th Century archive of recipes for artists’ materials ◦ Hamilton Kerr Institute, Fitzwilliam Museum ◦ http://www-hki.fitzmuseum.cam.ac.uk/archives/wn/  Lazurite – commercial database for painting research 21
  18. 18. 22
  19. 19.  De Mayerne/MOLART project for 20th Century Art in the Asia Pacific Region?  Shared but Secure, Cross-Disciplinary Knowledge Base for: ◦ Art conservators ◦ Curators ◦ Materials Scientists/Chemists ◦ Characterisation experts ◦ Information scientists  Social Semantic Network linking people, technologies, instruments & knowledge 23
  20. 20.  Google Earth type interfaces -> zoom into nanostructure  Animations -> show changes over time  Visualization of relationships, provenance trails  Artists’ births, dates, exhibitions, movement

  23. 23. 27
  24. 24.  Developed a Web Portal http://www.20thcpaint.org/  Developed security gateway of website  Developed interface and repository for locally generated data (characterisation and experimental data)  Developed ontologies (using AAT, CAMEO, plus domain experts) to link cross-disciplinary data ◦ Painting, Provenance, Materials, Techniques, Conservation  Next step – use the ontology + SPARQL queries to mediate between local and distributed DBs to answer complex queries
