Abstract

The system is available both in print and online versions. Names a few new subject headings in areas like science, technology, engineering and medicine (STEM). In this edition, there are a total of 1,600 new headings making it a total of 12,000+ preferred headings meant for subject access in small and medium sized libraries. This unprecedented increase of about 1,600 headings is mostly due the complete incorporation of the Canadian Sears last published independently in 2006. Also critically examines inconsistencies in a few headings. Concludes to say the new edition in resplendent, hard binding maintains its stellar reputation of a handy list of general subject headings both for applications and a teaching resource.

Abstract

Empfehlungssysteme tragen Inhalte individuell an Nutzer im WWW heran, basierend auf deren konkreten Bedürfnissen, Vorlieben und Interessen. Solche Systeme können Produkte, Services, Nutzer (mit analogen Interessen) uvm. vorschlagen und stellen damit - gerade im Web 2.0-Zeitalter - eine besondere Form der Personalisierung sowie des social networking dar. Damit bieten Empfehlungssysteme Anbietern im E-Commerce einen entscheidenden Marktvorteil, weshalb die Auswertung der Kundendaten bei großen Firmen wie Amazon, Google oder Ebay eine hohe Priorität besitzt. Aus diesem Grund wird im vorliegenden Artikel auf die Ansätze von Empfehlungssystemen, welche auf unterschiedliche Weise die Bedürfnisse des Nutzers aufgreifen bzw. "vorausahnen" und ihm Vorschläge (aus verschiedenen Bereichen) unterbreiten können, eingegangen. Der Artikel liefert eine Definition und Darstellung der Arbeitsweisen von Empfehlungssystemen. Dabei werden die verschiedenen Methodiken jener Dienste vergleichend erläutert, um ihre jeweiligen Vor- und Nachteile deutlich zu machen. Außerdem wird der Ontologie- und Folksonomy-Einsatz innerhalb von Empfehlungssystemen beleuchtet, um Chancen und Risiken der Anwendung von Methoden der Wissensrepräsentation für zukünftige Forschungsarbeiten einschätzen zu können.

Abstract

Discussion of the results and consequences of the automation project named thesaurus/concordance project, carried out at the DUT Library. The aim of the project was, by making the subject headings and their corresponding classification codes machine readable, to produce periodically cumulative lists, classifies lists, lists per subject fields, alphabetical lists of inverted subheadings and geographical names with their corresponding main headings and notations

Abstract

The history of the Library of Congress Subject Headings is traced, from its beginnings with the implementation of a dictionary catalog at the Library of Congress in 1898 to the present day. The author describes the most significant changes which have occurred in LCSH policies and practices during the 100-year period. Events noted near the end of the century indicate an increased willingness on the part of' the Library of Congress to involve the larger library community in the creation or revision of subject headings and other decision-making regarding the LCSH system. Finally, the author provides a summary of the other contributions to this collection of essays, a collection which celebrates the "centennial" of the world's most popular library subject heading language

Abstract

Surveys conducted during the last four years under the auspices of the International Federation of Library Associations and Organizations (IFLA) reveal that the Library of Congress Subject Headings is heavily used in national libraries outside of the United States, particularly in English-speaking countries. Many other countries report using a translation or adaptation of LCSH as their principal subject heading language. Magda Heiner-Freiling presents an analysis of the IFLA data, which also includes information on the classification schemes used by the libraries and whether or not the libraries have produced a manual on the creation and application of subject headings. The paper concludes with an Appendix showing the complete data from the 88 national libraries that respond to the surveys

Abstract

Zunächst wird die aktuelle Bedeutung digitaler Auskunft in der Informationsgesellschaft angesprochen. Anschließend folgt ein Überblick über den bislang erreichten Entwicklungsstand dieser relativ neuen Dienstleistung. Dabei werden die Vor- und Nachteile der technischen und organisatorischen Varianten erläutert. Schließlich richtet sich der Blick auf Qualitätskriterien zur Bewertung und Verbesserung digitaler Auskunft in der Praxis.

Content

"Die Ursprünge digitaler Auskunft reichen zurück in die 1980er Jahre. Aus bescheidenen Anfängen hat sich inzwischen eine bibliothekarische Standarddienstleistung entwickelt. Mit dem digitalen Umbruch stellten die Bibliotheken zunächst ihre Kataloge im Web für die Recherche bereit und boten FAQs zur Beantwortung von Standardfragen an. Um den vollen Umfang bibliothekarischer Dienstleistungen im Internet präsentieren zu können, bedurfte es darüber hinaus der Entwicklung eines Äquivalents für die klassische Auskunft im WWW. Die Entwicklung von digitaler Auskunft drängte sich aber nicht nur aus diesem Grund auf; das Web veränderte (und verändert) zudem die Informationskultur der Kunden; diese erwarten schnelleren und einfacheren Service. Alles soll so unmittelbar und so unkompliziert recherchierbar sein, wie man es von Google, Yahoo und anderen gewohnt ist. Außerdem hat die bibliothekarische Auskunft mit "Yahoo Clever" oder "Lycos IQ" kommerzielle Konkurrenten erhalten. Digitale Auskunft musste also als Antwort auf die Herausforderungen der kommerziellen Konkurrenz und der veränderten Benutzergewohnheiten schnell entwickelt werden. Denn nur so konnte und kann rechtzeitig unter Beweis gestellt werden, dass Bibliotheken für viele Auskunftsfälle gegenüber Suchmaschinen und Webkatalogen einen ungeheueren Vorteil besitzen: Die klassische und damit auch die digitale Auskunft zielt nicht darauf, die Fragen zu beantworten, die Benutzer stellen, sondern (idealerweise) darauf, ihnen die Informationen zu verschaffen, die sie tatsächlich benötigen.
Schon in der ersten Hälfte des 20. Jahrhunderts war in der Praxis des Auskunftsdienstes in den USA bekannt geworden, dass Benutzer häufig nicht nach dem fragen was sie eigentlich suchen, sondern meist allgemeine und nicht selten irreführende Fragen stellen. Dafür ist die Technik des Auskunftsinterviews entwickelt worden, um gemeinsam mit dem Kunden zu ermitteln, welche Informationen exakt gesucht werden. Während Suchmaschinen nur die syntaktische und (in Ausnahmefällen) die semantische Ebene der gestellten Frage abarbeiten können, vermag bibliothekarische Auskunft einer dritten, nämlich jener pragmatischen Dimension gerecht zu werden. Anders ausgedrückt: Suchmaschinen und andere Navigationsinstrumente des Internet arbeiten objektorientiert, digitale Auskunft durch bibliothekarische Experten hingegen erbringt subjekt- bzw. kundenorientierte Dienstleistungen. Bibliotheken mit elaborierter digitaler Auskunft sind den Herausforderungen der Informationsgesellschaft damit gewachsen: ja sie sind noch unverzichtbarer als zuvor. Speziell in Deutschland allerdings ist es nicht damit getan, digitale Auskunft mit Engagement zu entwickeln. Darüber hinaus müssen große Anstrengungen unternommen werden, um die Leistungsfähigkeit dieser bibliothekarischen Dienstleistung in das Bewusstsein der realen und potentiellen Kunden zu rücken."

Abstract

Within the multilingual framework of the CrissCross project, MACS (Multilingual Access to Subjects) has continued its work. MACS has developed a prototype of mappings between three vocabularies: the LCSH (Library of Congress Subject Headings), RAMEAU (Répertoire d'autorité-matière encyclopédique et alphabétique unifié) and the SWD (Schlagwortnormdatei). A database with a Link Management System (LMI), which allows for an easy linking between English, French and German subject headings, was created. The database started working with headings from the disciplines sports and theatre, but by now headings from all other fields of knowledge have been included as well. In 2008-2010, equivalencies between English and French headings which had been produced by the Bibliothèque nationale de France have been completed with the most important German SWD topical terms. Thus, more than 50.000 trilingual links are now available and can be used in different retrieval scenarios. It is planned to use them in The European Library (TEL) in order to support multilingual searches over all European National Library collections. The article informs about the project workflow, methodology of mapping and future applications of MACS links.
