    Abstract
    Der vollständige Projektname von Renardus lautet "Academic Subject Gateway Service Europe". Renardus wird von der Europäischen Union im 5. Rahmenprogramm mit dem Schwerpunktthema "Information Society Technologies" im zweiten Thematischen Programm "Benutzerfreundliche Informationsgesellschaft" ('Promoting a User-friendly Information Society') gefördert. Die Projektlaufzeit ist von Januar 2000 bis Juni 2002. Insgesamt zwölf Partner (Principal und Assistant Contractors) aus Finnland, Dänemark, Schweden, Großbritannien, den Niederlanden, Frankreich und Deutschland beteiligen sich an diesem Projekt. Die Europäische Union unterstützt das Projekt mit 1,7 Mio. EURO, die Gesamtkosten belaufen sich inklusive der Eigenbeteiligungen der Partner auf 2,3 Mio. EURO. Das Ziel des Projektes Renardus ist es, über eine Schnittstelle Zugriff auf verteilte Sammlungen von "High Quality" Internet Ressourcen in Europa zu ermöglichen. Diese Schnittstelle wird über den Renardus Broker realisiert, der das "Cross-Searchen" und "Cross-Browsen" über verteilte "Quality-Controlled Subject Gateways" ermöglicht. Ein weiteres Ziel von Renardus ist es, Möglichkeiten von "metadata sharing" zu evaluieren und in kleinen Experimenten zwischen z. B. Subject Gateways und Nationalbibliothek zu testen bzw. zu realisieren

    Abstract
    Library and Archives Canada (LAC) has capitalized on the Dewey Decimal Classification (DDC) potential for organizing Web resources in two projects. Since 1995, LAC has been providing a service that offers links to authoritative Web resources about Canada categorized according to the DDC via its Web site. More recently, LAC has partnered with the federal government Department of Canadian Heritage to manage Web content related to Canadian culture in a DDC-based subject tree. Although the DDC works well to organize a broadly-based collection, challenges have been encountered in adapting it for a specific subject domain.

    Abstract
    Multisource web news portals provide various advantages such as richness in news content and an opportunity to follow developments from different perspectives. However, in such environments, news variety and quantity can have an overwhelming effect. New-event detection and topic-tracking studies address this problem. They examine news streams and organize stories according to their events; however, several tracking stories of an event/topic may contain no new information (i.e., no novelty). We study the novelty detection (ND) problem on the tracking news of a particular topic. For this purpose, we build a Turkish ND test collection called BilNov-2005 and propose the usage of three ND methods: a cosine-similarity (CS)-based method, a language-model (LM)-based method, and a cover-coefficient (CC)-based method. For the LM-based ND method, we show that a simpler smoothing approach, Dirichlet smoothing, can have similar performance to a more complex smoothing approach, Shrinkage smoothing. We introduce a baseline that shows the performance of a system with random novelty decisions. In addition, a category-based threshold learning method is used for the first time in ND literature. The experimental results show that the LM-based ND method significantly outperforms the CS- and CC-based methods, and category-based threshold learning achieves promising results when compared to general threshold learning.

    Abstract
    Das von der Europäischen Union seit Januar 2000 geförderte Projekt Renardus hat das Ziel, einen Service zur Nutzung der in Europa vorhandenen "Quality-controlled Subject Gateways" aufzubauen, d.h. über einen Zugang bzw. eine Schnittstelle crosssearchen und crossbrowsen anzubieten. Für das crossbrowsen wird dabei zum Navigieren die Dewey Decimal Classification (DDC) verwendet. Der Beitrag beschreibt die einzelnen Entwicklungsschritte und stellt detailliert die nötigen Mappingprozesse vor. Dabei handelt es sich einmal um Mappingprozesse von den lokalen Metadatenformaten der einzelnen Subject Gateways zu dem gemeinsamen Kernset an Metadaten in Renardus für die Suche, wobei dieses Kernset auf dem Dublin Core Metadata Set basiert. Zum anderen geht es um die Erstellung von Konkordanzen zwischen den lokalen Klassen der Klassifikationssysteme der Partner und den DDC-Klassen für das Browsen. Der Beitrag beschreibt auch neue zugrunde liegende Definitionen bzw.theoretische Konzepte, die in der Metadatengemeinschaft zurzeit diskutiert werden (z.B. Application Profile, Namespace, Registry). Zum Schluss werden die Funktionalitäten des Renardus-Services (suchen, browsen) näher vorgestellt.

    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    This paper presents the approach and first results of the classification mapping process in the EU project Renardus. The outcome in Renardus is a cross-browsing feature based an the Dewey Decimal Classification (DDC) and improved subject searching across distributed and heterogeneous European subject gateways. The paper presents the project's initial experiences and decisions, e.g. an investigation of the use of classification systems by Renardus partners' gateways, general mapping approaches and issues, the definition of mapping relationships and some information an technical solutions and the mapping tool. There is also a demonstration of the use of the mapping information in Renardus and the presentation of several features that have been implemented to aid end-user navigation in a large and deep browsing structure like the DDC. Classification mapping for crossbrowsing is a labour intensive and complex effort which at the moment raises many open questions and leaves many more future potential work tasks than completed useful solutions.

    "1. The EU projeet Renardus Renardus is a project funded by the European Commission as part of the Information Society Technologies (IST) programme, part of the European Union's 5th Framework Programme. Partners in Renardus include national libraries, research centres and subject gateway services from Denmark, Finland, Germany, The Netherlands, Sweden and the UK, co-ordinated by the National Library of the Netherlands. The project aims to develop a Web-based service to enable searching and browsing across a range of distributed European-based information services designed for the academic and research communities - and in particular those services known as subject gateways. These gateways are services that provide access to Internet resources. They tend to be selective with regard to the resources they give access to, and are usually based an the manual creation of descriptive metadata. Services typically provide users with both search and browse facilities, and offen offer hierarchical browse structures based an subject classification schemes (Koch & Day, 1997). Predecessor projects like the EU project DESIRE have already developed solutions for the description of individual resources and for automatic classification at the level of an individual subject gateway using established classification systems. Renardus intends to develop a service that can cross-search and cross-browse a number of distributed subject gateways through the use of a common metadata profile and by the mapping all locally-used classification schemes to a common scheme. A thorough review of existing data models (Becker, et al., 2000) was used as the basis for the agreement of a minimum set of Dublin Core-based metadata elements that could be utilised as a common data model. A comprehensive mapping effort from the individual gateways' metadata element sets and content encoding schemes to the common profile has taken place. This provides the infrastructure for interoperability between all participating databases and thus is the necessary prerequisite for cross-searching."

    Abstract
    NOVAGate is a subject-based information gateway covering electronic resources in the agricultural, veterinary and related fields. The service, which opened in July 1998, is produced by the veterinary and agricultural libraries of the 5 Nordic countries - Denmark, Finland, Iceland, Norway and Sweden - which serve the NOVA University. The gateway covers Nordic and European resources as well as the resources of international organizations, but being planned is a network of subject gateways which will give access to a wide range of international quality resources within the agricultural, veterinary and related fields. The service uses the ROADS software

    Abstract
    The key political and strategic issues which needs to be addressed for the future development of the Australian subject gateways are: continued quality of content creation, integration of access to print and electronic resources, archiving and persistent identification, sustainability of services and service integration. These issues will be more effectively tackled internationally, and the Australian subject gateways are keen to work with international collaborators to achieve a mutually beneficial outcome

    Abstract
    The following describes a number of technologies and exemplary service designs that foster better Internet finding tools in libraries and more cooperative and efficient effort in Internet resource collection building. Our library and partner institutions have been involved in this work for over a decade. The open source software and projects discussed represent appropriate technologies and sustainable strategies that will help Internet portals, digital libraries, virtual libraries and library catalogs-with-portal-like-capabilities (IPDVLCs) to scale better and to anticipate and meet the needs of scholarly and educational users.

    Abstract
    While the Web has grown significantly in recent years, some portions of the Web remain largely underdeveloped, as shown in a lack of high-quality content and functionality. An example is the Arabic Web, in which a lack of well-structured Web directories limits users' ability to browse for Arabic resources. In this research, we proposed an approach to building Web directories for the underdeveloped Web and developed a proof-of-concept prototype called the Arabic Medical Web Directory (AMedDir) that supports browsing of over 5,000 Arabic medical Web sites and pages organized in a hierarchical structure. We conducted an experiment involving Arab participants and found that the AMedDir significantly outperformed two benchmark Arabic Web directories in terms of browsing effectiveness, efficiency, information quality, and user satisfaction. Participants expressed strong preference for the AMedDir and provided many positive comments. This research thus contributes to developing a useful Web directory for organizing the information in the Arabic medical domain and to a better understanding of how to support browsing on the underdeveloped Web.

    Abstract
    Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

    Abstract
    Libraries have had web presences since the introduction of the World Wide Web. Providing access to information provided by the library has been attempted through various means throughout the years but no method has been as popular or pervasive as the uses of library gateways and portals. Development of gateways and portals in libraries has been affected by many factors many of which have been outside the direct control of libraries or librarians. Both the history of library practice in this area and these external factors have had a substantial impact on the state of library portal and gateway development today.
