  • 1. JeromeDL the Semantic Digital Library
    • Sharing and Interconnecting Knowledge
    Chapter  Copyright 2007 Digital Enterprise Research Institute. All rights reserved. www.deri.org Chapter Digital Enterprise Research Institute www.deri.ie Digital Enterprise Research Institute www.deri.ie
  • 2. The World of Social Media
    • the Web is an ecosystem of social media
      • Flickr, blogs, wikipedia, etc.
      • blogosphere doubles every 6 months
    • Digital libraries need to participate in this ecosystem
      • contribute metadata to the ecosystem
      • leverage on the semantics
    3 Digital Enterprise Research Institute www.deri.ie
  • 3. Motivation
    • Corrib.DERI provides components for:
      • integration and search information from different sources
      • sharing and interconnecting knowledge among people
    4 Digital Enterprise Research Institute www.deri.ie
  • 4. 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
  • 5. 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

  • 6. 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.
      • Collaborative browsing and filtering.
      • Dynamic collections.
      • Integration with Web 2.0 services.

  • 8. Semantic Metadata and Services 10 Digital Enterprise Research Institute www.deri.ie
  • 9. Creating Semantics
    • Each resource is described with:
      • structure annotations - chapters, media parts, attachments
      • basic bibliographic annotations
      • knowledge organization systems - keywords, categories
      • other semantic annotations
      • social annotations (soft semantics)
    • Resource can be annotated with hard semantics during the uploading process
    demo Digital Enterprise Research Institute www.deri.ie
  • 10. Flexible access control
    • Identity management based on social networks
      • support for social networking metadata standard (FOAF)
      • users and authors are part of a community
    • Access control module
      • apply access control licenses to resources and services
      • defines atomic protections based on IP or position in the social network
      • is easily extensible
    demo Digital Enterprise Research Institute www.deri.ie
  • 11. 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 (beta)
      • refines query based on current context
      • extensible context definition: user profile, history of queries, current query, etc.
    demo Digital Enterprise Research Institute www.deri.ie
  • 12. Search Beyond one JeromeDL
    • Distributed search
      • Extensible Library Protocol
      • based on HyperCuP P2P infrastructure
    • Federated Search
      • Hierarchical order of JeromeDL instances
      • Exposing resources bottom-up
    • OAI-PMH (alpha)
      • Harvesting other libraries
      • Exposing resources to other libraries
    demo Digital Enterprise Research Institute www.deri.ie
  • 13. Browsing on semantics
    • Dynamic collections
      • specified with triples filter or RDF query
      • easily extensible
    • TagsTreeMaps
      • filtering based on clustered tags
      • using treemaps to present the tag space
      • zoomable interface paradigm
    demo demo Digital Enterprise Research Institute www.deri.ie
  • 14. Browsing on semantics
    • Exhibit (SIMILE, MIT)
      • powerful faceted filtering
      • rendering related dates on the timeline
      • rendering related places on the google maps
    • MultiBeeBrowse
      • collaborative browsing
      • allows to perform complex browsing operations
      • user can overview browsing context and look up browsing history
    demo demo Digital Enterprise Research Institute www.deri.ie
  • 15. Access to semantics
    • Exposing underlying semantics
      • rendering RDF in various flavors
      • exposing semantics in JSON and SIOC
      • syndication feeds (RSS)
    • Querying semantic database
      • RDF query endpoint
      • OAI-PMH (beta)
    • Delivering metadata to other services
      • MarcOnt Mediation Services

  • 17. Social Semantic Collaborative Filtering
    • Why?
      • The bottom-line of acquiring knowledge: informal communication (“word of mouth”)
    • How?
      • Everyone classifies (filters) the information in bookmark folders ( user-oriented taxonomy )
      • Peers share (collaborate over) the information ( community-driven taxonomy )
    • Result?
      • Knowledge “flows“ from the expert through the social network to the user
      • System amass a lot of information on user/community profile ( context )
    16 demo Digital Enterprise Research Institute www.deri.ie
  • 18. Towards Library 2.0
    • Users become active producers of the content and metadata
    • JeromeDL turns a single resources into a blog post:
      • users can annotate it
      • users can rank it
      • metadata about user annotations is exported in SIOC
    • Community annotations for multimedia (alpha):
      • region of interest (ROI) tagging in photos
      • time-tagging of video streams
    demo Digital Enterprise Research Institute www.deri.ie
  • 19. Beyond JeromeDL - connecting to Web 2.0
    • Other Web 2.0 services can easily hook up to information and services provided by JeromeDL
    • Example - notitio.us
      • aggregates semantics from different sources, including JeromeDL
      • involves users in providing more annotations
      • exposes content to other services, such as Learning Management Systems
      • contains components familiar from JeromeDL
    demo Digital Enterprise Research Institute www.deri.ie
  • 20. Conclusions
    • JeromeDL delivers a set of components that enables semantic web technology
    • It enhances users experience through the social interactions
    • It uses semantics existing on the web
    • It delivers semantics for other services
