    1. 1. Building a Heterogeneous Network of Digital Libraries on the Semantic Web Sebastian Ryszard Kruk , Mariusz Cygan, Piotr Piotrowski, Krystian Samp, Adam Westerski, Stefan Decker Digital Enterprise Research Institute National University of Ireland, Galway sebastian.kruk @deri.org http:// www.sebastiankruk.com /

    3. 3. Motivations
    4. 4. What is a Semantic Digital Library? <ul><li>Semantic digital libraries </li></ul><ul><ul><li>integrate information based on different metadata, e.g.: resources, user profiles, bookmarks, taxonomies </li></ul></ul><ul><ul><li>provide interoperability with other systems (not only digital libraries) on either metadata or communication level or both </li></ul></ul><ul><ul><li>delivering more robust, user friendly and adaptable search and browsing interfaces empowered by semantics </li></ul></ul>
    5. 5. Different Kind of Libraries (Evolution of Libraries) <ul><li>Classic libraries </li></ul><ul><li>Scientific libraries </li></ul><ul><li>Digital libraries </li></ul><ul><li>Semantic libraries </li></ul>
    6. 6. How are Semantic Digital Libraries different? <ul><li>Semantic digital libraries extend digital libraries by </li></ul><ul><ul><li>describing and exposing its resources in a machine ‘understandable’ way </li></ul></ul><ul><ul><li>resources can be </li></ul></ul><ul><ul><ul><li>contents, digital artefacts </li></ul></ul></ul><ul><ul><ul><li>organization of objects (e.g. collections) </li></ul></ul></ul><ul><ul><ul><li>users, user communities </li></ul></ul></ul><ul><ul><ul><li>controlled vocabularies, thesauri, taxonomies </li></ul></ul></ul><ul><ul><li>expose the semantics of their metadata in terms of an ontology </li></ul></ul><ul><ul><ul><li>defined using a formal language </li></ul></ul></ul><ul><ul><li>deliver mediation services for communication with other systems </li></ul></ul>
    7. 7. Benefits of Semantic Digital Libraries <ul><li>The two main benefits of Semantic Digital Libraries </li></ul><ul><li>new search paradigms for the information space </li></ul><ul><ul><li>Ontology-based search / facet search </li></ul></ul><ul><ul><li>Community-enabled browsing </li></ul></ul><ul><li>providing interoperability on the data level </li></ul><ul><ul><li>integrating metadata from various heterogeneous sources </li></ul></ul><ul><ul><li>Interconnecting different digital library systems </li></ul></ul>
    8. 8. JeromeDL - Introduction <ul><li>Joint effort of DERI International and Gdansk University of Technology (GUT) </li></ul><ul><li>Distributed under BSD Open Source license </li></ul><ul><li>Digital library build on semantic web technologies to answer requirements from: librarians, scientists and everyone. </li></ul><ul><li>A successor for prototype semantic digital library – Elvis-DL build at GUT </li></ul>
    9. 9. JeromeDL – Semantic D igital L ibrary <ul><li>Digital Library build with semantics and communities in mind </li></ul><ul><li>Build to reflect requirements of: </li></ul><ul><ul><li>Librarians </li></ul></ul><ul><ul><li>Researchers </li></ul></ul><ul><ul><li>Average users </li></ul></ul><ul><li>Ultimate goal – accessibility achieved through </li></ul><ul><ul><li>Interface design </li></ul></ul><ul><ul><li>Search and browsing technologies </li></ul></ul><ul><ul><li>In-depth internationalization effort </li></ul></ul>
