  • Pragmatic Evaluation of Folksonomies

    20th International Conference on World Wide Web (WWW2011)

    Recently, a number of algorithms have been proposed to obtain
    hierarchical structures — so-called folksonomies — from social
    tagging data. Work on these algorithms is in part driven by a belief
    that folksonomies are useful for tasks such as: (a) Navigating social
    tagging systems and (b) Acquiring semantic relationships between
    tags. While the promises and pitfalls of the latter have been studied to some extent, we know very little about the extent to which
    folksonomies are…

    Recently, a number of algorithms have been proposed to obtain
    hierarchical structures — so-called folksonomies — from social
    tagging data. Work on these algorithms is in part driven by a belief
    that folksonomies are useful for tasks such as: (a) Navigating social
    tagging systems and (b) Acquiring semantic relationships between
    tags. While the promises and pitfalls of the latter have been studied to some extent, we know very little about the extent to which
    folksonomies are pragmatically useful for navigating social tagging
    systems. This paper sets out to address this gap by presenting and
    applying a pragmatic framework for evaluating folksonomies. We
    model exploratory navigation of a tagging system as decentralized
    search on a network of tags. Evaluation is based on the fact that
    the performance of a decentralized search algorithm depends on
    the quality of the background knowledge used. The key idea of
    our approach is to use hierarchical structures learned by folksonomy algorithms as background knowledge for decentralized search.
    Utilizing decentralized search on tag networks in combination with
    different folksonomies as hierarchical background knowledge allows us to evaluate navigational tasks in social tagging systems.
    Our experiments with four state-of-the-art folksonomy algorithms
    on five different social tagging datasets reveal that existing folksonomy algorithms exhibit significant, previously undiscovered, differences with regard to their utility for navigation. Our results are relevant for engineers aiming to improve navigability of social tagging
    systems and for scientists aiming to evaluate different folksonomy
    algorithms from a pragmatic perspective.

  • eCloud - Europeana Cloud

    Europeana Cloud is changing the way that data is sent to Europeana, and giving researchers new tools to enrich and use that data. Our new cloud-based infrastructure will make it possible for:
    - Content providers and aggregators to efficiently store, share and provide access to digital cultural heritage;
    - Researchers to work on the content with new services and tools;
    - Everyone to feed back enriched data back into the cloud, for use by institutions and researchers alike.

    1,200 film and video clips
    850,000 images
    4.3 million texts (books, journal articles, theses, letters)
    Europeana Libraries created a valuable resource for scholars and built a robust network of national, university and research libraries, supported by Europe's major research library organisations.

    HIGHLIGHTS

    5 Million Objects: Digitised books, films and images are freely available online. Subjects range from Oriental manuscripts to Spanish civil war photographs and represent a wide geographical spread that covers the length and breadth of Europe.

    Full-text Indexing: This is the first cultural digitisation project that incorporates full-text indexing and searching capabilities. This creates the potential for in-depth academic study of all texts brought together by Europeana Libraries.

    Representation: Europeana Libraries provided research libraries with a platform to promote their collections to the widest possible audience. It lays the foundation on which a critical mass of research resources can be based.

    Aggregation: This project unites content from several libraries and creates a single channel for contributing library content to Europeana and The European Library. The model is efficient, cost-effective and capable of being extended to research libraries across Europe.

    High Quality Metadata: The quality and structure of library metadata will be improved. This will make online searching more accurate and user-friendly. New features such as timelines and maps will also be supported.
