- Abstract
- Open system protocols for search and retrieval have not provided explicit ways in which to implement thesaurus-aided searching. A number of different approaches within the existing protocols, as well as a proposed service, are evaluated. A general approach to implementing thesaurus-aided searching, particularly during consultation of a thesaurus, requires an entirely new service, whose main features are described

- Abstract
- Reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used included terms filtering, automatic indexing, and cluster analysis. The testbed for the research was the Worm Community System, which contains a comprehensive library of specialized community data and literature, currently in use by molecular biologists who study the nematode worm. The resulting worm thesaurus included 2709 researchers' names, 798 gene names, 20 experimental methods, and 4302 subject descriptors. On average, each term had about 90 weighted neighbouring terms indicating relevant concepts. The thesaurus was developed as an online search aide. Tests the worm thesaurus in an experiment with 6 worm researchers of varying degrees of expertise and background. The experiment showed that the thesaurus was an excellent 'memory jogging' device and that it supported learning and serendipitous browsing. Despite some occurrences of obvious noise, the system was useful in suggesting relevant concepts for the researchers' queries and it helped improve concept recall. With a simple browsing interface, an automatic thesaurus can become a useful tool for online search and can assist researchers in exploring and traversing a dynamic and complex electronic community system

- Abstract
- Beschäftigt man sich mit Inhaltserschließung, so sind zunächst zwei Dimensionen zu unterscheiden - die Wissensorganisationssysteme selbst (z. B. Normdateien, Thesauri, Schlagwortsprachen, Klassifikationen und Ontologien) und die Metadaten für Dokumente, die mit diesen Wissensorganisationssystemen erschlossen sind. Beides steht in einer Wechselwirkung zueinander: Die Wissensorganisationssysteme sind die Werkzeuge für die Erschließungsarbeit und bilden die Grundlage für die Erstellung konkreter Erschließungsmetadaten. Die praktische Anwendung der Wissensorganisationssysteme in der Erschließung wiederum ist die Basis für deren Pflege und Weiterentwicklung. Zugleich haben Wissensorganisationssysteme auch einen Eigenwert unabhängig von den Erschließungsmetadaten für einzelne Dokumente, indem sie bestimmte Bereiche von Welt- oder Fachwissen modellartig abbilden. Will man nun Aussagen über die Qualität von inhaltlicher Erschließung treffen, so genügt es nicht, den Input - also die Wissensorganisationssysteme und die damit generierten Metadaten - zu betrachten. Man muss auch den Output betrachten, also das, was die Recherchewerkzeuge daraus machen und was folglich bei den Nutzer:innen konkret ankommt. Im vorliegenden Beitrag werden Überlegungen zur Qualität von Recherchewerkzeugen in diesem Bereich angestellt - gewissermaßen als Fortsetzung und Vertiefung der dazu im Thesenpapier des Expertenteams RDA-Anwendungsprofil für die verbale Inhaltserschließung (ET RAVI) gegebenen Hinweise. Im Zentrum steht die verbale Erschließung nach den Regeln für die Schlagwortkatalogisierung (RSWK), wie sie sich in Bibliothekskatalogen manifestiert - gleich, ob es sich dabei um herkömmliche Kataloge oder um Resource-Discovery-Systeme (RDS) handelt.

- Abstract
- Contribution to the ongoing debate on the French subject headings list RAMEAU, which has been much criticised as time consuming and inflexible. Proposed technical solutions to recurring problems with complex syntax, strucutre of hierarchical and associative links, and rigity of language are discussed, in the context of computerised cataloguing and retrieval using OPACs. As a universal indexing language RAMEAU is more appropriate for medium sized specialised libraries and specialist researchers. However the 2 possible subject indexing techniques, linguistic treatment of whole text and thesaurus, are now beginning to be viewed as complementary approaches

- Abstract
- In der vorliegenden Form können die RSWK nicht befriedigen. Die geforderte hochdifferenzierte Erschließung ist in einem OPAC wegen der vielfältigen Abfragemöglichkeiten gar nicht nötig, ja eine einheitliche Indexierung und effiziente Suche is aufgrund der komplexen Regeln sogar erschwert. Aufgaben und Probleme der verbalen Sacherschließung in OPACs werden in dieser Arbeit aufgezeigt und Ansätze zu einer Alternative diskutiert. Der traditionelle Indexkatalog hat als Ergänzung des modernen Information Retrieval nur eine Zukunft, wenn die Möglichkeiten der EDV und der Faktor Mensch bei der Regelwerkentwicklung besser berücksichtigt werden

- Abstract
- Die Diskussion um Vor- und Nachteile von Präkoordination oder Postkoordination wird unter den in der verbalen Sacherschließung Engagierten in Deutschland seit Jahren geführt. Mit zunehmender Verbreitung der RSWK gewinnen die Überlegungen, die sich angesichts der Ausbreitung des OPAC für das 'Zerschlagen' der Schlagwortketten aussprechen, an Bedeutung. In diesem Zusammenhang trägt eine Berücksichtigung der internationalen Debatte um Prä- und Postkoordination zur Erweiterung des nationalen Horizontes bei. Der Beitrag ist eine leicht gekürzte Übersetzung eines Referates, das die Autorin beim IFLA Satellite Meeting zum Thema 'Subject indexing in the 90's - principles and practices' im August 1993 in Lissabon gehalten hat

- Abstract
- Das Prinzip, zur Wiedergabe eines komplexen Gegenstands mehrere Schlagwörter in Form einer Schlagwortkette zu verknüpfen, gehört zum zentralen Kern der 'Regeln für den Schlagwortkatalog' (RSWK). Während die Bildung solcher Schlagwortketten - also der Input - umfassend geregelt ist, verzichtet das Regelwerk jedoch darauf, auch für den Output nähere Vorgaben zu machen: "Die Gestaltung des Retrievals von Schlagwörtern und ihrer Anzeige im Online-Katalog" sei "Aufgabe des jeweiligen OPACs", weshalb man sich auf "einzelne Hinweise" beschränke (§ 20,1). Explizit genannt werden immerhin die "Suche nach Schlagwortketten" und das Browsing im Schlagwortkettenindex (5 20,5). Freilich ist seit langem bekannt, dass Schlagwortketten in vielen OPACs recht 'stiefmütterlich' behandelt werden. Eine aussagekräftige Bestandsaufnahme über die tatsächliche Nutzung der Schlagwortketten in aktuellen OPACs fehlte jedoch. Eine solche hat die Verfasserin im Februar 2008 unternommen. Den Hintergrund dafür bildeten die Überlegungen der vom Standardisierungsausschuss eingesetzten Ad-hoc-Arbeitsgruppe "Strategie der Sacherschließung" unter dem Vorsitz von Dr. Friedrich Geißelmann (UB Regensburg). In diesem Rahmen wurde auch über Wege diskutiert, um das große Potenzial der Schlagwortketten besser für das Retrieval nutzbar zu machen. Für die Untersuchung wurden - ohne Anspruch auf Vollständigkeit - 40 Online-Kataloge mit Schlagwortkettenfunktionalitäten analysiert. Zehn unterschiedliche Katalogsysteme waren dabei vertreten: Aleph, Allegro, Biber, Bond, Horizon, Libero, PICA, SISIS-Sunrise, Urica und Virtua. Eine Liste der betrachteten OPACs inkl. ihrer URLs und der im Folgenden verwendeten Siglen ist im Anhang zu finden. Die Darstellung stellt zwangsläufig eine Momentaufnahme dar, denn die OPACs sind natürlich keine statischen Systeme: Schon bei Abfassung des vorliegenden Beitrags im Juli 2008 waren einige Änderungen einzuarbeiten, die sich seit Februar ergeben hatten; weitere Umgestaltungen der Kataloge sind nur eine Frage der Zeit. Desungeachtet gibt die Studie einen Überblick über derzeit implementierte Funktionalitäten sowie aktuelle Trends, und ermöglicht auch das Aufzeigen von Problemfeldern und Verbesserungsmöglichkeiten.

- Abstract
- Die Kombination von gleichzeitig mehreren oder vielen intellektuell konstruierten Thesauri und maschineller Indexierung der Texte führt zu einer umfassenderen und spezifischeren Beschreibung von Dokumenten als die intellektuelle Klassifizierung oder die Indexierung allein. Durch die Expansion der Suchfrage um Thesauruseinträge wird der recall deutlich erhöht. Zugleich kann die intellektuelle Klassifizierung in überschaubaren Domänen dazu genutzt werden, baumartig in Dokumentenkollektionen zu navigieren oder die Suche erst in Teilbereichen der Klassifikation zu beginnen, um die precision zu erhöhen. Der Einsatz von Thesauruskollektionen wird an den Beispielen dandelon.com, Landtagsinformationssystem Vorarlberg und der Landeshomepage vorarlberg.at dargestellt.

- Abstract
- This paper discusses two inter-related themes: the retrieval potential of faceted thesauri and XML representations of fundamental facets. Initial findings are discussed from the ongoing 'FACET' project, in collaboration with the National Museum of Science and Industry. The work discussed seeks to take advantage of the structure afforded by faceted systems for multi-term queries and flexible matching, focusing in this paper an the Art and Architecture Thesaurus. A multi-term matching function yields ranked results with partial matches via semantic term expansion, based an a measure of distance over the semantic index space formed by thesaurus relationships. Our intention is to drive the system from general representations and a common query structure and interface. To this end, we are developing an XML representation based an work by the Classification Research Group an fundamental facets or categories. The XML representation maps categories to particular thesauri and hierarchies. The system interface, which is configured by the mapping, incorporates a thesaurus browser with navigation history together with a term search facility and drag and drop query builder.

- Abstract
- In online retrieval search results do not always match the intent in spite of using correct keywords (descriptors). One of the causes of this problem is found in the hierarchical structures of the thesaurus, which often contains relations between broader and narrower concepts, the opposite of which is not necessarily true. Some examples are described from 2 thesauri, MeSH and JICST. In these cases searchers need to make an effort to increase precision
