PELAGIOS Project Overview

  1. 1. PELAGIOSInterlinking Ancient World Research ResourcesThrough PlaceElton BarkerThe Open UniversityLeif IsaksenUniversity of SouthamptonRainer SimonAustrian Institute of TechnologyFebruary 2, 2012 | Berlin, Germany
  2. 2. What? | Aims of Pelagios Interlinking data about the Ancient World using Linked Open Data (LOD) methods Focus on place references (in maps, texts, images, database tables) Establishing simple “Pelagios Principles” to support contributors in preparing their data 2
  3. 3. Who? | The Pelagios Collective The Open University  Open Context University of Southampton  Perseus Digital Library Austrian Institute of Technology  Ptolemy Machine Pleiades  SPQR Arachne  Ure Museum Claros Fasti Online Google Ancient Places nomisma.org 3
  4. 4. How? | Don’t Unify the Model – Annotate! 4
  5. 5. How? | Don’t Unify the Model – Annotate!The Pelagios PrinciplesI. Annotate your place references with appropriate entries in the Pleiades GazetteerII. Publish annotations in the Open Annotation (OAC) RDF vocabulary 5
  6. 6. Why? | Piecing the Puzzle Together 6
  7. 7. Why? | Example: The Graph Explorer Exploring Relations between Exploring Relations between Places through Data Data through Place 7
  8. 8. Challenges | Some Issues Identified So Far Issues with automatic matching (data or in-house Gazetter)  Name-based matching based on Pleiades or Pleiades+ [1] toponyms  Followed by coordinate matching for verification/disambiguation Granularity & vague references (South Italy, Greek Islands) Location-based adjectives (Corinthian vs. Corinth) Typing of place references  Find spot vs. origin, “depicts”, etc.  Uncertain references (probably made in…, from the vicinity of…)[1] Pleiades+ toponym extension to Pleiades based on Geonames http://googleancientplaces.wordpress.com/pleiades/ 8
  9. 9. Discussion | Annotation vs. Unified Model The goal of Pelagios is to  create links rather than to aggregate and enrich  provide a toolkit & an API rather than a “single point of access” Pelagios requests that partners map  data to a vocabulary rather than their metadata schema to another The fact that Pelagios is limited in scope helps!  Restriction to Place  Very limited set of “primitives” – Dataset, (typed?) Annotation, Place 9
