ResearchSpace Platform in Use

  1. 1. Semantic Digital Humanities Workshop Oxford, September 2015 The Platform in Use Dr. Barry Norton Development Manager, ResearchSpace British Museum, London, UK
  2. 2. Knowledge Graph-based Disambiguation
  3. 3. Knowledge Graph-based Disambiguation
  4. 4. Knowledge Graph-based Disambiguation
  5. 5. Knowledge Graph-based Disambiguation
  6. 6. Knowledge Graph-based Disambiguation
  7. 7. Metadata from Knowledge Graph
  8. 8. Comparison with Wikipedia/DBpedia • Looks fairly familiar
  9. 9. Comparison with Wikipedia/DBpedia • Extracted to form a graph of fairly similar contents • But…
  10. 10. Comparison with Wikipedia/DBpedia • What is 114cm tall?
  11. 11. Comparison with Freebase
  12. 12. Comparison with Freebase
  13. 13. Comparison with Freebase
  14. 14. ResearchSpace • The ResearchSpace project: – is funded by the Andrew Mellon Foundation; – develops a set of cultural heritage research tools; – uses Metaphacts platform as a basis to reuse and combine these tools – • for each project using ResearchSpace, • for applications beyond cultural heritage; – configures and specialises these tools for data integrated using the CIDOC CRM ontology.
  15. 15. ResearchSpace Graph • Resources are typed into classes in rich poly- hierarchies: object/YCA62958 crm:E22_Man-Made_Object rdf:type crm:E19_Physical_Object crm:E24_Physical_Man-Made_Thing crm:E18_Physical_Thing crm:E71_Man-Made_Thing rdfs:subClassOf
  16. 16. ResearchSpace Graph • Different structural parts are represented as separate resources: object/YCA62958 crm:P65_shows_visual_item object/YCA62958/inscription/1 object/YCA62958/inscription/2 object/YCA62958/inscription/3 crm:E34_Inscription rdf:type
  17. 17. ResearchSpace Graph • The same separation of identity exists for non- tangible resources: object/YCA62958 crm:P108i_was_produced_by object/YCA62958/production crm:P24i_changed_ownership_through object/YCA62958/acquisition crm:P30i_custody_transferred_through
  18. 18. Navigating the Graph • Relation between simple entities (object, place) become complex to navigate: crm:P108i_was_produced_by ? ? ? ? ?
  19. 19. Querying the Graph • SPARQL queries are beyond most users: SELECT ?object ?place {?object (crm:P46i_forms_part_of | crm:P148i_is_component_of)* / crm:P92i_was_brought_into_existence_by / ^crm:P9_consists_of? / crm:P7_took_place_at / crm:P88i_forms_part_of* ?place}
  20. 20. Aim • Provide a search-based system that allows users to navigate relationships more abstractly: – Abstract nodes into 6 broad fundamental categories (FCs); – Abstract paths into fundamental relationships (FRs) between FCs; – Allow conjunctive search over FRs on a single FC domain; – Allow reuse of search definition/results (via FR) in new search; – Explain each search result in terms of underlying graph.
  21. 21. Fundamental Categories Things • Objects • Parts • Digital objects • Articles • Letters Actors • People • Org.s Places • Towns • Countries • Sites Times • Dates • Date ranges Events • Named events • Prod.s / Mod.s • Periods Concepts • Terms
  22. 22. FC Example crm:P108i_was_produced_by ? ? ? ? ? rso:Thing rso:Event rso:Place
  23. 23. Fundamental Relationships (1/n)
  24. 24. Fundamental Relationships (2/n)
  25. 25. FR Implementation (1/2) CONSTRUCT { ?thing rso:Thing_created_in_Event ?event ?event rso:Event_created_Thing ?thing} WHERE { ?event a rso:Event . ?thing a rso:Thing . ?thing (crm:P46i_forms_part_of | crm:P148i_is_component_of)* / crm:P92i_was_brought_into_existence_by / ^crm:P9_consists_of? ?event}
  26. 26. FR Implementation (2/2) CONSTRUCT { ?thing rso:Thing_created_at_Place ?place . ?place rso:Place_is_origin_of_Thing ?thing} WHERE { ?thing a rso:Thing . ?place a rso:Place . ?thing rso:Thing_created_in_Event / crm:P7_took_place_at / crm:P88i_forms_part_of* ?place}
  27. 27. FR Example crm:P108i_was_produced_by E1 E2 P1 P2 P3 rso:Thing rso:Event rso:Place T1 T2
  28. 28. FR Example crm:P108i_was_produced_by E1 E2 P1 P2 P3 T1 T2 T1 created in E1 T2 created in E2 T2 created in E1 T1 created at P1 T2 created at P2 T2 created at P3 T1 created at P2 T1 created at P3

  30. 30. Collections ca.12 ca.160 ca.20 19 Slide reused from Karageorghis, Kiely, Hermon et al. ‘Towards an integrated cross-disciplinary approach to the study of Salamis Terracotta Statues’
  31. 31. Basic Search for GRAVITATE objects • Objects can be found using places, actors (people and groups) and terminologies – Currently terminologies direct from Merlin
  32. 32. Type of Salamis statuary • Many shards of terracotta figures with some recognisable features (morphology)
  33. 33. Description of statuary From text: • Material: terracotta (known) • Object type: statue (known) – Modifier: over-lifesized • Morphology: hand & wrist – Modifiers: • Right hand • + Clenched
  34. 34. Morphology analysis
  35. 35. Morphology model • ResearchSpace must also: – link individual parts to (annotations over) 3D model – link these to an overall (complete) body morphology • but also allow assertions over sets of parts: – “these are all similar beards” – “these are all parts of the same statue”
  36. 36. Description of statuary • Further modifiers: – Fragment of left ear – Pierced lobe • etc.
  37. 37. Description of statuary From text: • Material: terracotta (known) & paint (?) – Modifier: black paint • Technique: painted • Object type: statue (known) • Morphology: head, hair & eyebrow
  38. 38. 38 A new color, previously un- observed - yellow - has been identified inside the earrings decoration. Materials analysis Slide reused from Karageorghis, Kiely, Hermon et al. ‘Towards an integrated cross-disciplinary approach to the study of Salamis Terracotta Statues’
  39. 39. 39 Techniques analysis Vertical marks Superimposition of incisions C2412, front side Various styles and coincidences of incision not currently recorded, but provide clues to families / re- assembly. Slide reused from Karageorghis, Kiely, Hermon et al. ‘Towards an integrated cross-disciplinary approach to the study of Salamis Terracotta Statues’
  40. 40. Challenges • How to attach scientific/geometric analysis to individual shards (BM to document model for GRAVITATE) • How to enrich search using these richer descriptions • How to assert over sets: – families – re-assemblies (possibly cross-collection) • How to enrich search over these sets
