- Abstract
- EconBiz, die Virtuelle Fachbibliothek Wirtschaftswissenschaften, wird gemeinsam von der Deutschen Zentralbibliothek für Wirtschaftswissenschaften (ZBW) und der Universitäts- und Stadtbibliothek Köln angeboten. Ein zentraler Bestandteil von EconBiz ist der Fachinformationsführer für Internetquellen, der derzeit über 16.000 Datensätze umfasst. Der Fachinformationsführer dient der Recherche nach Internetquellen und frei verfügbaren Volltexten. Die Erschließung dieser Quellen erfolgt arbeitsteilig durch bibliothekarisches und wissenschaftliches Personal im LinkShare System, einem System für die kooperative Erschließung und Verwaltung digitaler Netzobjekte. Nutzerinnen und Nutzer von EconBiz haben die Möglichkeit, Quellen für die Aufnahme in den Fachinformationsführer vorzuschlagen. Eine Beteiligung an der inhaltlichen Erschließung der Quellen erfolgt nicht. In Social-Bookmarking-Portalen wie "deLicio.us", "Furl" oder "Mister Wong" haben Nutzerinnen und Nutzer die Möglichkeit, eigene Listen mit Lesezeichen, englisch "Bookmarks", zu verwalten. Dazu bieten die verschiedenen Anbieter dieser Dienste allerhand nützliche Funktionen, u. a. mit folgenden Merkmalen: - Vergabe von Kategorien oder Schlagworten, so genannten "Tags", - Anlegen privater oder öffentlicher Bookmarks, - Abspeichern einer Version der Quelle. Derzeit üben diese Dienste eine sehr hohe Anziehungskraft auf Nutzerinnen und Nutzer aus, zum einen für die Verwaltung der eigenen Lesezeichen, zum anderen als Instrument für die Recherche nach relevanten Quellen. Mehr über das Potential und die Einsatzmöglichkeiten von Social-Bookmarking-Diensten möchte die ZBW im Rahmen eines Projekts "Inhaltserschließung durch Nutzerinnen und Nutzer" erfahren. Dafür wurde über einen begrenzten Zeitraum eine Teilmenge der im EconBiz-Fachinformationsführer enthaltenen Internetquellen in Social-Bookmarking-Webseiten angeboten. Ziel ist es, Erkenntnisse darüber zu gewinnen, in welchem Umfang diese von den Nutzerinnen und Nutzern der Socaial-Bookmarking-Dienste nachgenutzt und um eigene Schlagworte ergänzt werden.

Plieninger): "Der Aufbau digitaler Bibliotheken gilt manchen Unkundigen immer noch als Ei des Kolumbus, um mittels einer Digitalisierung umfangreicher Bestände Stellplatz und Finanzmittel zu sparen. Mittlerweile ist aber offenbar, dass auch die Digitalisierung einen nicht zu vernachlässigenden Aufwand bedeutet und das Problem der zukunftssicheren Aufbewahrung auch auf dieser Ebene immer noch nicht gelöst ist. Es ist somit weder einfach noch billig, entsprechende Vorhaben zu verwirklichen und nicht wenige Projekte sind zu einem Investitionsgrab verkommen. Um so erfreulicher, dass dieser Band nun einen Überblick über die Erfahrungen von koordinierten Forschungsprogrammen in den USA und Großbritannien von 1994 bis ca. 2002 gibt und Einblicke in Politik, Planung, Einrichtung und Handhabung der von diesen Programmen gesponserten Projekten erlaubt und dies aus unterschiedlichen Perspektiven. Im einleitenden Teil wird in zwei Kapiteln zunächst eine Übersicht über die Entwicklung der Forschungsprogramme in den USA und GB gegeben. Bei der Lektüre wird offenbar, wie viel im angelsächsischen Bereich in diesem Bereich investiert wurde und dass viele bekannte aktuelle Dienste, kostenlose als auch kommerzielle, in ihnen ihre Wurzeln haben. Insbesondere die Abhandlung über die USA sollte deutsche Bibliothekspolitiker interessieren, handelt es sich doch dabei um eine umfangreiche Finanzierung eines föderalen politischen Systems. Im darauf folgenden ersten Teil werden dann die Themenbereiche Ökonomie und Finanzierung, Inhaltsarten, Open Access, digitale Präservation und Evaluation von elektronischen Informationsdiensten eingehend behandelt. Es werden jeweils die Probleme und "Handlungsfelder" in allen Facetten dargestellt, welche sich beim Aufbau jeder digitalen Bibliothek stellen und gelöst werden müssen.

- Abstract
- There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This demonstration of a research prototype illustrates a matching function for compound descriptors, or multi-concept subject headings, that does not rely on exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based on a measure of semantic closeness between terms.The work is part of the EPSRC funded FACET project in collaboration with the UK National Museum of Science and Industry (NMSI) which includes the National Railway Museum. An export of NMSI's Collections Database is used as the dataset for the research. The J. Paul Getty Trust's Art and Architecture Thesaurus (AAT) is the main thesaurus in the project. The AAT is a widely used thesaurus (over 120,000 terms). Descriptors are organised in 7 facets representing separate conceptual classes of terms.The FACET application is a multi tiered architecture accessing a SQL Server database, with an OLE DB connection. The thesauri are stored as relational tables in the Server's database. However, a key component of the system is a parallel representation of the underlying semantic network as an in-memory structure of thesaurus concepts (corresponding to preferred terms). The structure models the hierarchical and associative interrelationships of thesaurus concepts via weighted poly-hierarchical links. Its primary purpose is real-time semantic expansion of query terms, achieved by a spreading activation semantic closeness algorithm. Queries with associated results are stored persistently using XML format data. A Visual Basic interface combines a thesaurus browser and an initial term search facility that takes into account equivalence relationships. Terms are dragged to a direct manipulation Query Builder which maintains the facet structure.
