- Abstract
- Modern fact databses contain abundant data classified through several classifications. Typically, users msut consult these classifications in separate manuals or files, thus making their effective use difficult. Contemporary database systems do little support deductive use of classifications. In this study we show how deductive data management techniques can be applied to the utilization of data value classifications. Computation of transitive class relationships is of primary importance here. We define a representation of classifications which supports transitive computation and present an operation-oriented deductive query language tailored for classification-based deductive information retrieval. The operations of this language are on the same abstraction level as relational algebra operations and can be integrated with these to form a powerful and flexible query language for deductive information retrieval. We define the integration of these operations and demonstrate the usefulness of the language in terms of several sample queries

- Abstract
- This paper presents an evaluation study of the navigation effectiveness of a multifaceted organizational taxonomy that was built on the Dewey Decimal Classification and several domain thesauri in the area of library and information science education. The objective of the evaluation was to detect deficiencies in the taxonomy and to infer problems of applied construction steps from users' navigation difficulties. The evaluation approach included scenario-based navigation exercises and postexercise interviews. Navigation exercise errors and underlying reasons were analyzed in relation to specific components of the taxonomy and applied construction steps. Guidelines for the construction of the hierarchical structure and categories of an organizational taxonomy using existing general classification schemes and domain thesauri were derived from the evaluation results.

- Abstract
- Dewey Decimal Classification has been used to organize materials owned by the three scientific libraries at the University of Pavia, and to allow integrated browsing in their union catalogue through SciGator, a home built web-based user interface. Classification acts as a bridge between collections located in different places and shelved according to different local schemes. Furthermore, cross-discipline relationships recorded in the system allow for expanded queries that increase recall. Advantages and possible improvements of such a system are discussed.

- Abstract
- We investigate facets of online health information that are preferred, easy-to-use and useful in accessing online consumer health information from a user's perspective. In this study, the existing classification structure of 20 top ranked consumer health information websites in South Korea were analyzed, and nine facets that are used in organizing health information in those websites were identified. Based on the identified facets, an online survey, which asked participants' preferences for as well as perceived ease-of-use and usefulness of each facet in accessing online health information, was conducted. The analysis of the survey results showed that among the nine facets, the "diseases & conditions" and "body part" facets were most preferred, and perceived as easy-to-use and useful in accessing online health information. In contrast, "age," "gender," and "alternative medicine" facets were perceived as relatively less preferred, easy-to-use and useful. This research study has direct implications for organization and design of health information websites in that it suggests facets to include and avoid in organizing and providing access points to online health information.

- Abstract
- Der Beitrag berichtet über eine unter der Bibliothekssoftware "Aleph 500" neu eingerichtete Normdatei, die mehrere "koexistierende" lokale Klassifikationssysteme aus den Bibliotheken des Österreichischen Bibliothekenverbundes aufzunehmen vermag. Implementiert wurden darin als erste Klassifikation jene der Universitätsbibliothek Bodenkultur (Wien), für die nach dem Auslaufen einer früheren Softwarelösung eine neue Plattform gesucht worden war. Folgende Aspekte werden im Detail angesprochen bzw. dokumentiert: Struktur und Besonderheiten dieser Klassifikation, Gliederung des Gesamtprojektes in mehrere Phasen und Realisierung der ersten Phase (Tabellen-Setup inkl. Kategorienschema, Überführung der Daten in die neue Normdatei, Indexierung). Die neue Multi-Klassifikations-Normdatei ist bereit für die Aufnahme weiterer lokaler Systematiken, wobei diese einerseits von den an der Verbundzentrale geführten Lokalsystemen, andererseits aber auch von den anderen Lokalsystemen des Verbundes stammen können.

- Abstract
- Die traditionellen Verfahren der klassifikatorischen sachlichen Erschließung von Medieninhalten heben auf die Eindeutigkeit der Zuordnung von Objekt (Medieninhalt) und Klasse ab. Sie unterscheiden sich damit in der Praxis des Online-Retrievals nur unwesentlich von den Verfahren der verbalen sachlichen Erschließung (z.B. Thesauri, SWD/RSWK). Auf der Grundlage der in der Sacherschließungstheorie vorgenommenen Unterscheidung von klassifikatorischer und verbaler Sacherschließung werden mögliche und bereits in Anwendung befindliche Verfahren diskutiert, welche die begrifflichen Kontexte der Klassen für den Anwender einer bibliothekarischen Klassifikation im Online-Retrieval nutzbar machen
