    1. 1. JeromeDL the Semantic Digital Library <ul><li>Sharing and Interconnecting Knowledge </li></ul>Chapter  Copyright 2007 Digital Enterprise Research Institute. All rights reserved. Chapter Digital Enterprise Research Institute Digital Enterprise Research Institute
    2. 2. The World of Social Media <ul><li>the Web is an ecosystem of social media </li></ul><ul><ul><li>Flickr, blogs, wikipedia, etc. </li></ul></ul><ul><ul><li>blogosphere doubles every 6 months </li></ul></ul><ul><li>Digital libraries need to participate in this ecosystem </li></ul><ul><ul><li>contribute metadata to the ecosystem </li></ul></ul><ul><ul><li>leverage on the semantics </li></ul></ul>3 Digital Enterprise Research Institute
    3. 3. Motivation <ul><li>Corrib.DERI provides components for: </li></ul><ul><ul><li>integration and search information from different sources </li></ul></ul><ul><ul><li>sharing and interconnecting knowledge among people </li></ul></ul>4 Digital Enterprise Research Institute
    4. 4. Yesterday’s world of digital content <ul><li>Digital library </li></ul><ul><ul><li>Database and archive (storage) </li></ul></ul><ul><ul><li>Digital bibliographic descriptions (metadata) </li></ul></ul><ul><ul><li>Full-text search (interface) </li></ul></ul><ul><li>Pros: </li></ul><ul><ul><li>Content accessible online </li></ul></ul><ul><ul><li>Federations of libraries – visit less places </li></ul></ul><ul><li>Cons: </li></ul><ul><ul><li>Lonely user </li></ul></ul><ul><ul><li>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) </li></ul></ul><ul><ul><li>Still many problems with interconnecting other sources, incl. libraries </li></ul></ul>6 Digital Enterprise Research Institute
    5. 5. Today of interconnected, social media <ul><li>Social Semantic Information Spaces </li></ul><ul><ul><li>Semantic description (interconnected metadata) </li></ul></ul><ul><ul><li>Annotations provided by users (social metadata) </li></ul></ul><ul><ul><li>Collaborative search and browsing (interface) </li></ul></ul><ul><li>Features </li></ul><ul><ul><li>Search and browsing based on semantics empowers users </li></ul></ul><ul><ul><li>Users contribute to the classification process </li></ul></ul><ul><ul><li>Users can understand community driven annotations </li></ul></ul><ul><ul><li>Users enhance digital content using blogs, wikis on the side </li></ul></ul><ul><ul><li>Library can interact with other Internet services </li></ul></ul>7 Digital Enterprise Research Institute

    8. 8. Semantic Metadata and Services 10 Digital Enterprise Research Institute
    9. 9. Creating Semantics <ul><li>Each resource is described with: </li></ul><ul><ul><li>structure annotations - chapters, media parts, attachments </li></ul></ul><ul><ul><li>basic bibliographic annotations </li></ul></ul><ul><ul><li>knowledge organization systems - keywords, categories </li></ul></ul><ul><ul><li>other semantic annotations </li></ul></ul><ul><ul><li>social annotations (soft semantics) </li></ul></ul><ul><li>Resource can be annotated with hard semantics during the uploading process </li></ul>demo Digital Enterprise Research Institute
    10. 10. Flexible access control <ul><li>Identity management based on social networks </li></ul><ul><ul><li>support for social networking metadata standard (FOAF) </li></ul></ul><ul><ul><li>users and authors are part of a community </li></ul></ul><ul><li>Access control module </li></ul><ul><ul><li>apply access control licenses to resources and services </li></ul></ul><ul><ul><li>defines atomic protections based on IP or position in the social network </li></ul></ul><ul><ul><li>is easily extensible </li></ul></ul>demo Digital Enterprise Research Institute
    11. 11. Search based on semantics <ul><li>Natural language templates </li></ul><ul><ul><li>allows to perform complex queries using natural language </li></ul></ul><ul><ul><li>can be created and modified based on the needs of users </li></ul></ul><ul><ul><li>easily internationalized </li></ul></ul><ul><li>Semantic Query Expansion (beta) </li></ul><ul><ul><li>refines query based on current context </li></ul></ul><ul><ul><li>extensible context definition: user profile, history of queries, current query, etc. </li></ul></ul>demo Digital Enterprise Research Institute
    12. 12. Search Beyond one JeromeDL <ul><li>Distributed search </li></ul><ul><ul><li>Extensible Library Protocol </li></ul></ul><ul><ul><li>based on HyperCuP P2P infrastructure </li></ul></ul><ul><li>Federated Search </li></ul><ul><ul><li>Hierarchical order of JeromeDL instances </li></ul></ul><ul><ul><li>Exposing resources bottom-up </li></ul></ul><ul><li>OAI-PMH (alpha) </li></ul><ul><ul><li>Harvesting other libraries </li></ul></ul><ul><ul><li>Exposing resources to other libraries </li></ul></ul>demo Digital Enterprise Research Institute

Towards Library 2.0 <ul><li>Users become active producers of the content and metadata </li></ul><ul><li>JeromeDL turns a single resources into a blog post: </li></ul><ul><ul><li>users can annotate it </li></ul></ul><ul><ul><li>users can rank it </li></ul></ul><ul><ul><li>metadata about user annotations is exported in SIOC </li></ul></ul><ul><li>Community annotations for multimedia (alpha): </li></ul><ul><ul><li>region of interest (ROI) tagging in photos </li></ul></ul><ul><ul><li>time-tagging of video streams </li></ul></ul>demo Digital Enterprise Research Institute
    19. 19. Beyond JeromeDL - connecting to Web 2.0 <ul><li>Other Web 2.0 services can easily hook up to information and services provided by JeromeDL </li></ul><ul><li>Example - </li></ul><ul><ul><li>aggregates semantics from different sources, including JeromeDL </li></ul></ul><ul><ul><li>involves users in providing more annotations </li></ul></ul><ul><ul><li>exposes content to other services, such as Learning Management Systems </li></ul></ul><ul><ul><li>contains components familiar from JeromeDL </li></ul></ul>demo Digital Enterprise Research Institute
