- Abstract
- Das VZG-Projekt Colibri/DDC beschäftigt sich seit 2003 mit automatischen Verfahren zur Dewey-Dezimalklassifikation (Dewey Decimal Classification, kurz DDC). Ziel des Projektes ist eine einheitliche DDC-Erschließung von bibliografischen Titeldatensätzen und eine Unterstützung der DDC-Expert(inn)en und DDC-Laien, z. B. bei der Analyse und Synthese von DDC-Notationen und deren Qualitätskontrolle und der DDC-basierten Suche. Der vorliegende Bericht konzentriert sich auf die erste größere automatische DDC-Klassifizierung und erste automatische und intellektuelle Bewertung mit der Klassifizierungskomponente vc_dcl1. Grundlage hierfür waren die von der Deutschen Nationabibliothek (DNB) im November 2007 zur Verfügung gestellten 25.653 Titeldatensätze (12 Wochen-/Monatslieferungen) der Deutschen Nationalbibliografie der Reihen A, B und H. Nach Erläuterung der automatischen DDC-Klassifizierung und automatischen Bewertung in Kapitel 2 wird in Kapitel 3 auf den DNB-Bericht "Colibri_Auswertung_DDC_Endbericht_Sommer_2008" eingegangen. Es werden Sachverhalte geklärt und Fragen gestellt, deren Antworten die Weichen für den Verlauf der weiteren Klassifizierungstests stellen werden. Über das Kapitel 3 hinaus führende weitergehende Betrachtungen und Gedanken zur Fortführung der automatischen DDC-Klassifizierung werden in Kapitel 4 angestellt. Der Bericht dient dem vertieften Verständnis für die automatischen Verfahren.

- Abstract
- Describes the final phase of the work on the ELINOR (Electronic Library INformation Online Retrieval) project at De Montfort University, Leicester, which concluded in 1996. ELINOR was 2 phase project with 3 overall goals: to create a practical pilot system based on a commercial product (Excalibur EFS); to investigate the expansion of a small scale electronic library to a larger, distributed library system; and to develop a more efficient and effective means of accessing and sharing resources within a networked multi campus institution. ELINOR was successful in demonstrating that libraries may conveniently digitize and supply smal collections of high demand materials over a campus network in text anf TIFF format. Operational conditions have so far indicated that the barriers are not technological but involve copyright, use issues and sustainability

- Abstract
- The SAC Subcommittee on Subject Relationships/Reference Structures was authorized at the 1995 Midwinter Meeting and appointed shortly before Annual Conference. Its creation was one result of a discussion of how (and why) to promote the display and use of broader-term subject heading references, and its charge reads as follows: To investigate: (1) the kinds of relationships that exist between subjects, the display of which are likely to be useful to catalog users; (2) how these relationships are or could be recorded in authorities and classification formats; (3) options for how these relationships should be presented to users of online and print catalogs, indexes, lists, etc. By the summer 1996 Annual Conference, make some recommendations to SAC about how to disseminate the information and/or implement changes. At that time assess the need for additional time to investigate these issues. The Subcommittee's work on each of the imperatives in the charge was summarized in a report issued at the 1996 Annual Conference (Appendix A). Highlights of this work included the development of a taxonomy of 165 subject relationships; a demonstration that, using existing MARC coding, catalog systems could be programmed to generate references they do not currently support; and an examination of reference displays in several CD-ROM database products. Since that time, work has continued on identifying term relationships and display options; on tracking research, discussion, and implementation of subject relationships in information systems; and on compiling a list of further research needs.

- Abstract
- A project to design a graphical user interface for the OKAPI online catalogue search system which uses the basic term weighting probabilistic search engine. Presents a research context of the project with a discussion of interface and functionality issues relating to the design of OPACs. Describes the design methodology and evaluation methodology. Presents the preliminary results of the field trial evaluation. Considers problems encountered in the field trial and discusses contributory factors to the effectiveness of interactive query expansion. Highlights the tension between usability and functionality in highly interactive retrieval and suggests further areas of research

- Abstract
- Im Rahmen des CrissCross-Projekts wurde ein multilinguales, thesaurusbasiertes Recherchevokabular zu heterogen erschlossenen Dokumenten geschaffen. Dieses Recherchevokabular besteht unter anderem aus den Sachschlagwörtern der Schlagwortnormdatei (SWD) und den Notationen der Dewey-Dezimalklassifikation (DDC). Die Schlagwortnormdatei bietet einen normierten, terminologisch kontrollierten Wortschatz an. Sie enthält Schlagwörter aus allen Fachgebieten und Schlagwortkategorien, die durch die beteiligten Bibliotheken zur verbalen Inhaltserschließung genutzt und dabei täglich aktualisiert werden. Unter anderem wird die Schlagwortnormdatei auch zur verbalen Erschließung der Deutschen Nationalbibliografie verwendet. Während der verbalen Erschließung wird jedem Inhalt mindestens eine Schlagwortfolge zugewiesen. Schlagwortfolgen werden dazu benutzt, um die komplexen Themen eines Dokuments zu beschreiben. Zusätzlich wird für den Neuerscheinungsdienst der Deutschen Nationalbibliografie seit dem Jahrgang 2004 jeder Titel noch mindestens einer Sachgruppe zugewiesen. Die Strukturierung der Sachgruppen orientiert sich dabei weitestgehend an der zweiten Ebene der Dewey-Dezimalklassifikation. Die Dewey-Dezimalklassifikation ist eine international weit verbreitete Universalklassifikation. Von ihr existieren zahlreiche Übersetzungen, u. a. ins Deutsche. Seit Januar 2006 wird die DDC gemeinsam mit der SWD zur Inhaltserschließung in der Deutschen Nationalbibliografie verwendet. Bei der Inhaltserschließung mit Hilfe der DDC wird jedem Inhalt eine einzelne DDC-Notation zugewiesen. Komplexe Themen werden dabei durch die Synthese von zwei oder mehr Notationen zu einer neuen Notation dargestellt. Somit ist die DDC-Notation sowohl vergleichbar mit SWD-Schlagwörtern als auch mit ganzen Schlagwortfolgen.

- Abstract
- The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project
