  • Transcript

    • 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
      7 Digital Enterprise Research Institute www.deri.ie
    • 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.

    • 7. Metadata and Services in JeromeDL 9 Digital Enterprise Research Institute www.deri.ie
    • 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
      demo Digital Enterprise Research Institute www.deri.ie
    • 16. Semantic Metadata and Services 15 Digital Enterprise Research Institute www.deri.ie
    • 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
      Digital Enterprise Research Institute www.deri.ie
    • 21.
      • JeromeDL brings Semantic Web and Online Communities to the Digital Libraries
      • as the Digital Library on Social Semantic Information Spaces
