Abstract

Facet analysis is an established methodology for building classifications and subject indexing systems, but has been less rigorously applied to thesauri. The process of creating a compatible thesaurus from the schedules of the Bliss Bibliographic Classification 2nd edition highlights the ways in which the conceptual relationships in a subject field are handled in the two types of retrieval languages. An underlying uniformity of theory is established, and the way in which software can manage the relationships is discussed. The manner of displaying verbal expressions of concepts (vocabulary control) is also considered, but is found to be less well controlled in the classification than in the thesaurus. Nevertheless, there is good reason to think that facet analysis provides a sound basis for structuring a variety of knowledge organization tools.

Abstract

The Bliss Bibliographic Classification is the only example of a fully faceted general classification scheme in the Western world. Although it is the object of much interest as a model for other tools it suffers from the lack of a web presence, and remedying this is an immediate objective for its editors. Understanding how this might be done presents some challenges, as the scheme is semantically very rich and complex in the range and nature of the relationships it contains. The automatic management of these is already in place using local software, but exporting this to a common data format needs careful thought and planning. Various encoding schemes, both for traditional classifications, and for digital materials, represent variously: the concepts; their functional roles; and the relationships between them. Integrating these aspects in a coherent and interchangeable manner appears to be achievable, but the most appropriate format is as yet unclear.

Abstract

Many information professionals working in small units today fail to find the published tools for subject-based organization that are appropriate to their local needs, whether they are archivists, special librarians, information officers, or knowledge or content managers. Large established standards for document description and organization are too unwieldy, unnecessarily detailed, or too expensive to install and maintain. In other cases the available systems are insufficient for a specialist environment, or don't bring things together in a helpful way. A purpose built, in-house system would seem to be the answer, but too often the skills necessary to create one are lacking. This practical text examines the criteria relevant to the selection of a subject-management system, describes the characteristics of some common types of subject tool, and takes the novice step by step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. Key areas covered are: What is a thesaurus? Tools for subject access and retrieval; what a thesaurus is used for? Why use a thesaurus? Examples of thesauri; the structure of a thesaurus; thesaural relationships; practical thesaurus construction; the vocabulary of the thesaurus; building the systematic structure; conversion to alphabetic format; forms of entry in the thesaurus; maintaining the thesaurus; thesaurus software; and; the wider environment. Essential for the practising information professional, this guide is also valuable for students of library and information science.

Footnote

In einem abschliessenden Kapitel geht das Buch auf Thesauruspflege und -verwaltung ein, wobei auch das Thema "Thesaurussoftware" angerissen wird - letzteres vielleicht ein wenig zu kurz. Erst hier mag manchem unbefangenen Leser bewusst werden, dass die in den vorhergehenden Kapiteln dargestellte Methodik eigentlich ohne den Einsatz dezidierter Software besprochen wurde, ja vielleicht auch so besprochen werden musste, um ein entsprechendes Verständnis herzustellen. In der nachfolgenden zweiseitigen Conclusio wird erwähnt, dass die britische Norm Structured Vocabularies for Information Retrieval (BS 8723) vor einer Neufassung stehe - was den Rezensenten darauf hinzuweisen gemahnt, dass sich dieses Buch natürlich ausschliesslich auf den anglo-amerikanischen Sprachraum und die dort geltenden Thesaurus-Gepflogenheiten bezieht. Der relativ umfangreiche Anhang beinhaltet ausser Materialie zum erwähnten Demonstrationsbeispiel auch ein nützliches Glossarium sowie ein professionell gefertigtes Sachregister. Literaturhinweise werden - in sparsamer Dosierung - jeweils am Ende der einzelnen Kapitel gegeben, sodass sich die "Bibliography" am Ende des Buches auf einige Normen und zwei Standardwerke beschränken kann. Realistisch betrachtet, darf vermutlich nicht davon ausgegangen werden, dass Leser, die dieses Buch durchgearbeitet haben, sogleich in der Lage sein werden, eigenständig einen Thesaurus zu erstellen. Ein Lehrbuch allein kann weder einen Kurs noch die praktische Erfahrung ersetzen, die für eine solche Tätigkeit vonnöten sind. Ich kann mir aber gut vorstellen, dass die Kenntnis der in diesem Buch vermittelten Inhalte sehr wohl in die Lage versetzt, in einem Team, das einen Thesaurus erstellen soll, kompetent mitzuarbeiten, mit den Konzepten und Fachtermini zurechtzukommen und selbst konstruktive Beiträge zu leisten. Ausserdem erscheint mir das Werk hervorragend als Begleitmaterial zu einer Lehrveranstaltung geeignet - oder auch als Grundlage für die Planung einer solchen. Ein britischer Einführungstext eben, im besten Sinne."
