- Abstract
- A rationale for self-instruction in thesaurus making is presented. Some definitions of a thesaurus are given and sources suitable to begin self-tuition indicated. A sound grasp of grammar is emphasized and appropriate readings and exercises recommended. Readings in classification, facet analysis, and subject cataloging are described. An approach for deconstruction and reconstruction of sections of classification systems and thesauri is proposed and explained. Procedures for using exercises in thesaurus construction are detailed. The means of examining individual thesauri is suggested. The availability and use of free software are described. The creation of opportunities for self-learning is considered.

- Abstract
- Moderne Verfahren des Information Retrieval verlangen nach aussagekräftigen und detailliert relationierten Dokumentationssprachen. Der selektive Transfer einzelner Modellierungsstrategien aus dem Bereich semantischer Technologien für die Gestaltung und Relationierung bestehender Dokumentationssprachen wird diskutiert. In Form einer Taxonomie wird ein hierarchisch strukturiertes Relationeninventar definiert, welches sowohl hinreichend allgemeine als auch zahlreiche spezifische Relationstypen enthält, die eine detaillierte und damit aussagekräftige Relationierung des Vokabulars ermöglichen. Das bringt einen Zugewinn an Übersichtlichkeit und Funktionalität. Im Gegensatz zu anderen Ansätzen und Überlegungen zur Schaffung von Relationeninventaren entwickelt der vorgestellte Vorschlag das Relationeninventar aus der Begriffsmenge eines bestehenden Gegenstandsbereichs heraus.

- Abstract
- Das Buch gibt einen umfassenden Überblick über vorhandene Thesauri und Klassifikationen. Es liefert detaillierte Beschreibungen zu mehr als 150 Klassifikationen und Thesauri aus Naturwissenschaften, Technik, Wirtschaft und Patentwesen. Da gegenwärtig eine aktuelle Zusammenstellung international verfügbarer Thesauri und Klassifikationen fehlt, schließt das vorliegende Buch diese Lücke und kann somit dazu beitragen, Doppelarbeit bei der Erstellung von Thesauri und Klassifikationen zu verhindern und den intellektuellen wie kostenintensiven Aufwand zu minimieren. Zusätzlich bietet dieses Nachschlagewerk mit einem umfangreichen Index den Informationsspezialisten Unterstützung bei der Formulierung präziser Rechercheanfragen, indem es Informationen über Vorhandensein, Aufbau und Verfügbarkeit der Thesauri und Klassifikationen bereitstellt, die für die Recherche genutzt werden können. Das Buch wendet sich an alle Information Professionals, die Dokumentationssprachen aufbauen und nutzen.

- Rez. in: Information: Wissenschaft & Praxis 56(2005) H.5/6, S.337 (W. Ratzek): "Bettina Brühl legt mit "Thesauri und Klassifikationen" ein Fleißarbeit vor. Das Buch mit seiner Auswahl von über 150 Klassifikationen und Thesauri aus Naturwissenschaft, Technik, Wirtschaft und Patenwesen macht es zu einem brauchbaren Nachschlagewerk, zumal auch ein umfassender Index nach Sachgebieten, nach Datenbanken und nach Klassifikationen und Thesauri angeboten wird. Nach einer 13-seitigen Einführung (Kapitel 1 und 2) folgt mit dem 3. Kapitel die "Darstellung von Klassifikationen und Thesauri", im wesentlichen aus den Beschreibungen der Hersteller zusammengestellt. Hier werden Dokumentationssprachen der Fachgebiete - Naturwissenschaften (3.1) und deren Spezialisierungen wie zum Beispiel "Biowissenschaften und Biotechnologie", "Chemie" oder "Umwelt und Ökonomie", aber auch "Mathematik und Informatik" (?) auf 189 Seiten vorgestellt, - Technik mit zum Beispiel "Fachordnung Technik", "Subject Categories (INIS/ ETDE) mit 17 Seiten verhältnismäßig knapp abgehandelt, - Wirtschaft mit "Branchen-Codes", "Product-Codes", "Länder-Codes"",Fachklas-sifikationen" und "Thesauri" ausführlich auf 57 Seiten präsentiert, - Patente und Normen mit zum Beispiel "Europäische Patentklassifikation" oder "International Patent Classification" auf 33 Seiten umrissen. Jedes Teilgebiet wird mit einer kurzen Beschreibung eingeleitet. Danach folgen die jeweiligen Beschreibungen mit den Merkmalen: "Anschrift des Erstellers", "Themen-gebiet(e)", "Sprache", "Verfügbarkeit", "An-wendung" und "Ouelle(n)". "Das Buch wendet sich an alle Information Professionals, die Dokumentationssprachen aufbauen und nutzen" heißt es in der Verlagsinformation. Zwar ist es nicht notwendig, die informationswissenschaftlichen Aspekte der Klassifikationen und Thesauri abzuhandeln, aber ein Hinweis auf die Bedeutung der Information und Dokumentation und/oder der Informationswissenschaft wäre schon angebracht, um in der Welt der Informations- und Wissenswirtschaft zu demonstrieren, welchen Beitrag unsere Profession leistet. Andernfalls bleibt das Blickfeld eingeschränkt und der Anschluss an neuere Entwicklungen ausgeblendet. Dieser Anknüpfungspunkt wäre beispielsweise durch einen Exkurs über Topic Map/Semantic Web gegeben. Der Verlag liefert mit der Herausgabe die ses Kompendiums einen nützlichen ersten Baustein zu einem umfassenden Verzeichnis von Thesauri und Klassifikationen."

- Abstract
- Es ist ein semantisches Netz für den Gegenstandsbereich Luftfahrt modelliert worden, welches Unternehmensinformationen, Organisationen, Fluglinien, Flughäfen, etc. enthält, Diese sind 10 Hauptkategorien zugeordnet worden, die untergliedert nach Facetten sind. Die Begriffe des Gegenstandsbereiches sind mit 23 unterschiedlichen Relationen verknüpft worden (Z. B.: 'hat Standort in', bietet an, 'ist Homebase von', etc). Der Schwerpunkt der Betrachtung liegt auf dem Unterschied zwischen den drei klassischen Standardrelationen und den zusätzlich eingerichteten Relationen, bezüglich ihrem Nutzen für ein effizientes Retrieval. Die angelegten Kategorien und Relationen sind sowohl für eine kognitive als auch für eine maschinelle Verarbeitung geeignet.
Das Ziel der vorliegenden Arbeit ist es, ein Modell für ein Informationssystems zu erstellen und die Voraussetzungen und Aspekte zu betrachten, die notwendig sind, um Einsichten in die begrifflichen Zusammenhänge des Gegenstandsbereiches Luftfahrt zu erlangen. Der Ansatz, der hier erläutert wird, plädiert für die Konstruktion einer begrifflichen Wissensstruktur in Form eines semantischen Netzes. Ausgangspunkt dieser Überlegungen ist die Auffassung, daß zwar das kontrollierte Vokabular eines Thesaurus mit seiner Verweisstruktur vielfältiges Wissen enthält, das aber aufgrund der drei klassischen Standardrelationen nur unzureichend repräsentiert und damit auch nur beschränkt zugänglich ist. Es wird erläutert, welche Vorteile eine Erweiterung der drei Thesaurusrelationen erbringen kann und in welcher Funktion die Relationen bei der Formulierung der Suchanfrage unterstützend sein können. Gezeigt wird, wie die Begriffstrukturen eines semantischen Netzes deutlicher hervortreten, wenn bei der Erstellung einer Wissensstruktur eines Gegenstandsbereiches Kategorien zugrunde gelegt werden und welche Gestaltungsprinzipien den Suchprozeß unterstützen können. Dazu werden die Voraussetzungen erörtert, die garantieren, daß komplexe Suchanfragen (erfolgreich) geleistet werden können und zu präzisen Treffermengen führen.

- Abstract
- Der Thesaurus als Dokumentationssprache wird in der DIN 1463-1in seinen wesentlichen Merkmalen beschrieben. Dort wird der Thesaurus im informationswissenschaftlichen Sinne so definiert: "Ein Thesaurus im Bereich der Information und Dokumentation ist eine geordnete Zusammenstellung von Begriffen und ihren (vorwiegend natürlichsprachigen) Bezeichnungen, die in einem Dokumentationsgebiet zum Indexieren, Speichern und Wiederauffinden dient. Er ist durch folgende Merkmale gekennzeichnet: a) Begriffe und Bezeichnungen werden eindeutig aufeinander bezogen ("terminologische Kontrolle"), indem - Synonyme möglichst vollständig erfasst werden, - Homonyme und Polyseme besonders gekennzeichnet werden, - für jeden Begriff eine Bezeichnung (Vorzugsbenennung, Begriffsnummer oder Notation) festgelegt wird, die den Begriff eindeutig vertritt, b) Beziehungen zwischen Begriffen (repräsentiert durch ihre Bezeichnungen) werden dargestellt." Diese Definition wäre zu ergänzen um folgende: c) Der Thesaurus ist präskriptiv, indem er für seinen Geltungsbereich festlegt, welche begrifflichen Einheiten zur Verfügung gestellt werden und durch welche Bezeichnungen diese repräsentiert werden. Im Folgenden sollen die wichtigsten Elemente und Prinzipien von Thesauri und die Thesaurusmethodik vorgestellt werden. Dies kann in diesem Rahmen nur auf eine sehr kursorische und allgemeine Art und Weise geschehen. Außerdem beschränkt sich die Darstellung auf den Thesauruseinsatz im klassischen Bereich von Information und Dokumentation. Auf die Behandlung von Spezialproblemen oder auf besondere Thesaurusformen (z.B. mehrsprachige Thesauri) kann hier nicht eingegangen werden, ebenso auf die erweiterten Anforderungen, die an Thesauri im Kontext von Wissensrepräsentation oder Hypertext zu stellen sind. Allerdings überschneidet sich der klassische IuD-Bereich zunehmend mit erweiterten Formen (etwa im Rahmen von Internetanwendungen). Da der Thesaurus im dokumentarischen Sinn alle Grundelemente des Thesaurusprinzips in klarer Form aufweist, wird dieser Bereich für eine Einführung gewählt. Für eine intensivere Auseinandersetzung mit der Thematik wird die Lektüre von Wersig empfohlen, auf den sich auch die folgenden Ausführungen in weiten Teilen stützen. Eine weitere grundsätzliche Einführung in diesen Bereich, allerdings eher ausgerichtet auf die Spezifika des englischen Sprachraums, findet sich bei Lancaster.

- Abstract
- The patterns of overlap between terms which are closely related in a thesaurus are considered. The relationships considered are parent/child, in which one term is a broader term of the other, and sibling in which to 2 terms share the same broader term. The patterns of overlap observed in the MeSH thesaurus with respect to selected MEDLINE postings are examined. The implications of the overlap patterns are discussed, in particular, the impact of the overlap patterns on the potential effectiveness of a proposed algorithm for handling negation is considered.

- Abstract
- A thesaurus in the controlled vocabulary environment is a tool designed to support effective infonnation retrieval (IR) by guiding indexers and searchers consistently to choose the same terms for expressing a given concept or combination of concepts. Terms in the thesaurus are linked by relationships of three well-known types: equivalence, hierarchical, and associative. The functions and properties of these three basic types and some subcategories are described, as well as some additional relationship types conunonly found in thesauri. Progressive automation of IR processes and the capability for simultaneous searching of vast networked resources are creating some pressures for change in the categorization and consistency of relationships.

- Abstract
- The benefits of a well constructed thesaurus to an information retrieval system have long been recognised by both researchers and practitioners in the field. Examines both early and current approaches to automatic thesaurus construction and describes an approach to the automatic generation of global thesauri based on the term discrimination value model of Salton Yang, and Yu and on an appropriate clustering algorithm. This method has been implemented and applied to 2 document collections. Preliminary results indicate that this method, which produces improvements in retrieval performance in excess of 10 and 15% in the test collections, is viable and worthy of continued investigation.

- Abstract
- The purpose of this selected bibliography is to introduce issues and problems in relation to thesaurus construction and to present a set of readings that may be used in practical thesaurus design. The concept of thesaurus is discussed, the purpose of the thesaurus and how the concept has evolved over the years according to new IR technologies. Different approaches to thesaurus construction are introduced, and readings dealing with specific problems and developments in the collection, formation and organisation of thesaurus concepts and terms are presented. Primarily manual construction methods are discussed, but the bibliography also refers to research about techniques for automatic thesaurus construction.

- Abstract
- After a period of experiment and evolution in the 1950s and 1960s, a fairly standard format for thesauri was established with the publication of the influential Thesaurus of Engineering and Scientific Terms (TEST) in 1967. This and other early thesauri relied primarily an the presentation of terms in alphabetical order. The value of a classified presentation was subsequently realised, and in particular the technique of facet analysis has profoundly influenced thesaurus evolution. Thesaurofacet and the Art & Architecture Thesaurus have acted as models for two distinct breeds of thesaurus using faceted displays of terms. As of the 1990s, the expansion of end-user access to vast networked resources is imposing further requirements an the style and structure of controlled vocabularies. The international standards for thesauri, first conceived in a print-based era, are badly in need of updating. Work is in hand in the UK and the USA to revise and develop standards in support of electronic thesauri.

- Abstract
- The need for Persian thesauri became apparent during the late 1960s with the advent of documentation centres in Iran. The first Persian controlled vocabulary was published by IRANDOC in 1977. Other centres worked on translations of existing thesauri, but it was soon realised that these efforts did not meet the needs of the centres. After the Islamic revolution in 1979, the foundation of new centres intensified the need for Persian thesauri, especially in the fields of history and government documents. Also, during the Iran-Iraq war, Iranian research centres produced reports in scientific and technical fields, both to support military requirements and to meet society's needs. In order to provide a comprehensive thesaurus, the Council of Scientific Research of Iran approved a project for the compilation of such a work. Nowadays, 12 Persian thesauri are available and others are being prepared, based on the literary corpus and conformity with characteristics of Iranian culture.
