Transcript

  • 1. Annotations, Tags & Linked Data Metadata Enrichment in Online Map Collections through Volunteer-Contributed Information Rainer Simon , Joachim Jung Austrian Institute of Technology Bernhard Haslhofer Cornell University 6 th International Workshop on Digital Approaches in Cartographic Heritage April 7, 2011 | The Hague, Netherlands
  • 2. Part of Europeana Connect EU Project Core Components for the European Digital Library www.europeanaconnect.eu EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContent plus
  • 3. EuropeanaConnect | End-User Media Annotation
    • Provide basis for knowledge exchange , communication & cooperative research
    • Create an incentive to engage with the matter more deeply
    • Facilitate community building
    • Harness volunteer effort to collect additional metadata
    EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContent plus
  • 4. YUMA Map Annotation Prototype | Features & Goals
    • Tile-based viewing based on OpenLayers (for now) and MagickTiler 1
    • Free-text annotation & semantic tagging
      • Geographical features in the annotated area via Geonames
      • Named entities mentioned in the annotation (places, persons, epochs,...) via DBpedia Spotlight
    • Tools for shape drawing and (basic) geo-referencing creation
    • Place search , map overlay , shape export to KML
    • RSS feeds on maps, annotations and users
    • Designed for integration into a host portal
    • Currently in prototype stage (and with experimental features – beware! )
    • Open Source! http://github.com/yuma-annotation

  • 5. Without Further Ado | The Screencast(s) EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContent plus
  • 6. Linked Data | Some Basics and Some Benefits
    • Basics 1
      • URIs for as names for things
      • HTTP URIs so we can get information about those things
      • http://dbpedia.org/resource/Gibraltar
      • http://sws.geonames.org/2411585/
      • http://dme.ait.ac.at/yuma-server/api/annotation/39
      • (Typed) Links to other URIs so we can discover more things
      • Many relevant datasets out there already!
    • Benefits (for map search)
      • Multilingual & synonym search
      • Spatial metadata & geographical search – control points as by-products of annotation?
    1 Berners-Lee, Tim (2006) Linked Data – Design Issues. http://www.w3.org/DesignIssues/LinkedData.html EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContent plus
  • 7. Towards Evaluating YUMA | The COMPASS Experiment
    • Building Ground Truth
      • 6.306 maps from the Library of Congress (batch converted to Zoomify)
      • Original map metadata
      • 130.935 (anonymous) user search queries
      • Custom Web application for collecting relevance judgements
      • First stage: corpus of 400 sample queries
    • Preliminary Results
      • Users invited from MapHist and IFLA DIGLIB, INETBIB mailing lists
      • 75 participants, 12+ countries, 1.800+ judgements (approx. 45% of target)

  • 8. Towards Evaluating YUMA | The COMPASS Experiment EuropeanaConnect is coordinated by the Austrian National Library Co-funded by the European Community Programme eContent plus
  • 9. Outlook | Next Steps
    • Next Steps COMPASS
      • Social features
      • Integration with YUMA
      • Dissemination!
    • Next Steps YUMA
      • User Interface and Usability
      • Standards! OAC 1 and OGC
      • Geo-referencing by (approximate) projections in addition to control points?
