  • JeromeDL - the Semantic Digital Library

    1. 1. JeromeDL the Semantic Digital Library Sebastian R. Kruk, Stefan Decker
    2. 2. Outline <ul><li>Motivation </li></ul><ul><li>From paper books to social media </li></ul><ul><li>Semantic services in JeromeDL </li></ul><ul><li>Social services in JeromeDL </li></ul><ul><li>Metadata in use in JeromeDL </li></ul><ul><li>Semantic DL in eLearning and Museums </li></ul><ul><li>Conclusions </li></ul>
    3. 3. Social Semantic Information Spaces
    4. 4. Motivation (1) <ul><li>How to integrate and search information from different sources? </li></ul>
    5. 5. Motivation (2) <ul><li>How to share and interconnect knowledge in a digital library? </li></ul>
    6. 6. The old days of paper books <ul><li>Library: </li></ul><ul><ul><li>Archive (storage space) </li></ul></ul><ul><ul><li>Bibliographic cards (metadata) </li></ul></ul><ul><ul><li>Librarian (interface) </li></ul></ul><ul><li>Pros: </li></ul><ul><ul><li>Someone to talk to, to explain, to help in searching </li></ul></ul><ul><ul><li>Library as a meeting place </li></ul></ul><ul><li>Cons: </li></ul><ul><ul><li>Based on physical location </li></ul></ul><ul><ul><li>Libraries are not connected – we have to visit every place </li></ul></ul>
    7. 7. 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 (different) libraries </li></ul></ul>
