    • 8. Outline
      • Motivation
      • Ontologies in the world of digital libraries
      • JeromeDL – Social Semantic Digital Library
      • MarcOnt – Collaborative ontology development
      • Geo-tagging
    • 9. Motivation
      • World of Digital Libraries
      • Identified Problems:
      • Interoperability
      • Format translation
      • Multiple data formats in DL:
      • How to support them?
      • How to translate between them?
      • Who should create mappings?
    • 10. Real-life problems – user’s expectations
      • Searching:
      • Effective and Accurate
      • We want correct and fast answers!!
      • Intuitive and Simple
      • Asking questions should be easy.
      • Meaning
      • Jaguar – a car or an animal?
      • Reasoning
      • Give me articles written by students of X in Galway?
      • Identified problems:
      • Intuitive interface for asking complex querries
    • 11. Real-life problems - summary
      • Digital Libraries should provide:
      • Interoperability
      • Support for many (legacy) formats
      • Complex search features
      • Intuitive interfaces
    • 12. Yesterday’s world of digital content
      • Digital library
        • Database and archive (storage)
        • Digital bibliographic descriptions (metadata)
        • Full-text search (interface)
      • Pros:
        • Content accessible online
        • Federations of libraries – visit less places
      • Cons:
        • Lonely user
        • No one to talk to, we need to find the right keywords, what if we do not know them (“man without an ear” paintings example)
        • Still many problems with interconnecting other sources, incl. libraries
      6 Digital Enterprise Research Institute www.deri.ie
    • 13. Today of interconnected, social media
      • Social Semantic Information Spaces
        • Semantic description (interconnected metadata)
        • Annotations provided by users (social metadata)
        • Collaborative search and browsing (interface)
      • Features
        • Search and browsing based on semantics empowers users
        • Users contribute to the classification process
        • Users can understand community driven annotations
        • Users enhance digital content using blogs, wikis on the side
        • Library can interact with other Internet services
      7 Digital Enterprise Research Institute www.deri.ie
    • 14. JeromeDL - Properties
      • JeromeDL is the social semantic digital library that provides
        • Integrated social networking with user profiling.
        • Enhanced personalized search facility.
        • Interconnects meaningful description of resources with social media.
        • Extensible access control based on social networks.

    • 15. Metadata and Services in JeromeDL Digital Enterprise Research Institute www.deri.ie
    • 16. Creating Semantics
      • Each resource is described with:
        • structure annotations - chapters, media parts, attachments
        • basic bibliographic annotations
        • knowledge organization systems - keywords, categories
        • social annotations (soft semantics)
        • Geotags
      • Resource can be annotated with hard semantics during the uploading process
      Digital Enterprise Research Institute www.deri.ie

    • 18. Ontologies in JeromeDL
    • 19. Search based on semantics
      • Natural language templates
        • allows to perform complex queries using natural language
        • can be created and modified based on the needs of users
        • easily internationalized
      • Semantic Query Expansion (alpha)
        • refines query based on current context
        • extensible context definition: user profile, history of queries, current query, etc.
      Digital Enterprise Research Institute www.deri.ie
    • 20. Access to semantics
      • Exposing underlying semantics

    • 44. Geotagging
      • Geotagging ( Geocoding ) is the process of adding geographical identification metadata to various media such as websites, RSS feeds, or images. This data usually consists of latitude and longitude coordinates , though it can also include altitude and place names
      • Geocoding also refers to the process of taking non-coordinate based geographical identifiers, such as a postal address, and assigning geographic coordinates to them (or vice versa).
    • 45. Geotags
    • 46. Examples
      • Geo-tags
        • geotagged
        • geo:lat=51.483387
        • geo:lon=-3.169792
      • Geo-Metatags
        • <meta name=&quot;geo.placename&quot; content=&quot;Cardiff, Cardiff, UK&quot; />
        • <meta name=&quot;geo.position&quot; content=&quot;51.483387;-3.169792&quot; />
        • <meta name=&quot;geo.region&quot; content=&quot;GB-Wales&quot; />
        • <meta name=&quot;ICBM&quot; content=&quot;51.483387, -3.169792&quot; />
    • 47. Flickr
    • 48. Exhibit
    • 49. Why geo-tagging?
      • Geotagging can help users find a wide variety of location-specific information.
        • find images taken near a given location by entering latitude and longitude coordinates into a Geotagging-enabled image search engine.
        • n ews
        • w ebsites
        • other resources.
      • Determine the localisation of a given „concept” in the scene

    • 50. Copernicus in action
    • 51. Summary
      • Semantics can bring digital libraries to a new level of providing services.
      • There is a need for usable and community based appication that would allow annotations (Semantic Web + Web 2.0).
      • Search and browsing services are crucial from the user’s perspective.
