    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.

    Abstract
    Music websites are ubiquitous, and music downloads, such as MP3, are a major source of Web traffic. As the amount of musical content increases and the Web becomes an important mechanism for distributing music, we expect to see a rising demand for music search services. Many currently available music search engines rely on file names, song title, composer or performer as the indexing and retrieval mechanism. These systems do not make use of the musical content. We believe that a more natural, effective, and usable music-information retrieval (MIR) system should have audio input, where the user can query with musical content. We are developing a system called MusArt for audio-input MIR. With MusArt, as with other audio-input MIR systems, a user sings or plays a theme, hook, or riff from the desired piece of music. The system transcribes the query and searches for related themes in a database, returning the most similar themes, given some measure of similarity. We call this "retrieval by query." In this paper, we describe the architecture of MusArt. An important element of MusArt is metadata creation: we believe that it is essential to automatically abstract important musical elements, particularly themes. Theme extraction is performed by a subsystem called MME, which we describe later in this paper. Another important element of MusArt is its support for a variety of search engines, as we believe that MIR is too complex for a single approach to work for all queries. Currently, MusArt supports a dynamic time-warping search engine that has high recall, and a complementary stochastic search engine that searches over themes, emphasizing speed and relevancy. The stochastic search engine is discussed in this paper.

    Abstract
    Nach mehr als 4 Jahren Erfahrung in der kooperativen Erschließung von Internetquellen öffnet sich der Verbund Academic LinkShare für neue Partner aus den Geistes-, Regional- und Sozialwissenschaften. Academic LinkShare ist ein Netzwerk wissenschaftlicher Bibliotheken. Gemeinsam bauen sie einen interdisziplinären Datenpool fachlich relevanter Internetquellen auf, aus dem sich alle Partner gleichberechtigt bedienen können. Nach mehr als vier Jahren gemeinsamer Entwicklungs- und Erschließungsarbeit lässt sich der Erfolg des Modells heute quantifizieren. Seit der Aufnahme des ersten Datensatzes Mitte 2001 sind weit mehr als 20.000 Quellen aus dem politik-, rechts-, wirtschafts- und sozialwissenschaftlichen Umfeld dazugekommen. Sie werden präsentiert in den Fachinformationsführern (qualifizierten Linksammlungen) von ViFaPol (Politikwissenschaft - http://www.vifapol.de), EconBiz (Wirtschaftswissenschaften - http://www.econbiz.de) und ViFa Recht (Rechtswissenschaft - http://www.vifa-recht.de). Jüngstes Mitglied des Verbundes sind die Europäischen Dokumentationszentren mit ihrem Rechercheportal ArchiDok (http://archidok.uni-mannheim.de). Die Einsparpotentiale liegen vor allem im hohen Überschneidungsgrad der Quellen, der - ohne Volltexte - bei ca. 30% liegt. Die Schaffung einer gemeinsamen technischen Infrastruktur allein begründet noch nicht den Erfolg des Modells. Viel schwieriger als die Entwicklung eines Erfassungssystems ist der Aufbau eines funktionierenden Netzwerks wissenschaftlicher Einrichtungen und Bibliotheken, das sich nachhaltig für den Aufbau des Datenpools verantwortlich zeichnet. Vor dem Hintergrund überaus knapper Zeitressourcen hat Academic LinkShare technische und organisatorische Lösungen entwickelt, die den Voraussetzungen der Kooperationspartner gerecht werden. Dieses Win-Win-Prinzip zahlt sich aus. Neben den fünf Verbundpartnern von Academic LinkShare beteiligen sich heute mehr als 40 wissenschaftliche Einrichtungen an der Erschließung der Quellen. Das Interesse an dem Modell des Metadata Sharing ist beachtlich - der Kreis der Mitwirkenden wächst kontinuierlich an. Academic LinkShare bietet Interessenten aus dem sozial-, geistes- und regionalwissenschaftlichen Umfeld die Möglichkeit, dem Verbund beizutreten, und unterstützt sie dabei auf der Basis der vorhandenen technischen Lösungen beim Aufbau und Betrieb einer eigenen Virtuellen Fachbibliothek.
