Abstract

Es werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für eine Reform der RSWK im Hinblick auf die Erfordernisse der OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Im vergangenen Jahr wurden die Ergebnisse der Expertengruppe mit dem Schwerpunkt Formalerschließung vorgelegt, nun folgen die Aussagen zur Sacherschließung, welche die Expertengruppe - in veränderter personeller Zusammensetzung unter Leitung von Dr. Friedrich Geißelmann, Regensburg - erarbeitet hat. Die bibliothekarische Öffentlichkeit ist aufgefordert, sich dazu bis zum Jahresende zu äußern. Beide Berichte beziehen sich aufeinander und versuchen, den Zusammenhang zwischen Formal- und Sacherschließung herzustellen. Vom gegenwärtigen Stand der Sacherschließung in deutschen Bibliotheken ausgehend - wozu auch durch die Gruppe im Frühjahr 1993 eine Umfrage in wissenschaftlichen und Öffentlichen Bibliotheken gemacht worden ist, werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für ein Reform der RSWK im Hinblick auf die Erfordernisse des OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Es geht um Kettenbildung und Permutationsregeln, Kompositumbildung oder Zerlegung von Begriffen, Pleonasmus, Funktion der SWD, Ansetzung von Schlagwörtern, die Einführung eines Zeit-Codes, Erschließung literarischer Formen und Gattungen, den verwendeten Zeichensatz, den Umgang mit Verweisungen

Abstract

Der 70. Band der BIPRA-Reihe beschäftigt sich mit der Qualität in der Inhaltserschließung im Kontext etablierter Verfahren und technologischer Innovationen. Treffen heterogene Erzeugnisse unterschiedlicher Methoden und Systeme aufeinander, müssen minimale Anforderungen an die Qualität der Inhaltserschließung festgelegt werden. Die Qualitätsfrage wird zurzeit in verschiedenen Zusammenhängen intensiv diskutiert und im vorliegenden Band aufgegriffen. In diesem Themenfeld aktive Autor:innen beschreiben aus ihrem jeweiligen Blickwinkel unterschiedliche Aspekte zu Metadaten, Normdaten, Formaten, Erschließungsverfahren und Erschließungspolitik. Der Band versteht sich als Handreichung und Anregung für die Diskussion um die Qualität in der Inhaltserschließung.

Abstract

Information or Document Retrieval is the subject of this book. It is not an introductory book, although it is self-contained in the sense that it is not necessary to have a background in the theory or practice of Information Retrieval in order to understand its arguments. The book presents, as clearly as possible, one particular perspective on Information Retrieval, and attempts to say that certain aspects of the theory or practice of the management of documents are more important than others. The majority of Information Retrieval research has been aimed at the more experimentally tractable small-scale systems, and although much of that work has added greatly to our understanding of Information Retrieval it is becoming increasingly apparent that retrieval systems with large data bases of documents are a fundamentally different genre of systems than small-scale systems. If this is so, which is the thesis of this book, then we must now study large information retrieval systems with the same rigor and intensity that we once studied small-scale systems. Hegel observed that the quantitative growth of any system caused qualitative changes to take place in its structure and processes.

Abstract

Over the past ten years, various organizations, both public and private, have expressed interest in implementing FAST in their cataloging workflows. As interest in FAST has grown, so too has interest in knowing how FAST is being used and by whom. Since 2002 eighteen institutions (see table 1) in six countries have expressed interest in learning more about FAST and how it could be implemented in cataloging workflows. Currently OCLC is aware of nine agencies that have actually adopted or support FAST for resource description. This study, the first systematic census of FAST users undertaken by OCLC, was conducted, in part, to address these inquiries. Its purpose was to examine: how FAST is being utilized; why FAST was chosen as the cataloging vocabulary; what benefits FAST provides; and what can be done to enhance the value of FAST. Interview requests were sent to all parties that had previously contacted OCLC about FAST. Of the eighteen organizations contacted, sixteen agreed to provide information about their decision whether to use FAST (nine adopters, seven non-adopters).

Rez. in: Knowledge organization 34(2007) no.1, S.58-60 (P. Buizza): "This Nuovo soggettario is the first sign of subject indexing renewal in Italy. Italian subject indexing has been based until now on Soggettario per i cataloghi delle biblioteche italiane (Firenze, 1956), a list of preferred terms and see references, with suitable hierarchical subdivisions and cross references, derived from the subject catalogue of the National Library in Florence (BNCF). New headings later used in Bibliografia nazionale italiana (BNI) were added without references, nor indeed with any real maintenance. Systematic instructions on how to combine the terms are lacking: the indexer using this instrument is obliged to infer the order of terms absent from the lists by consulting analogous entries. Italian libraries are suffering from the limits of this subject catalogue: vocabulary is inadequate, obsolete and inconsistent, the syndetic structure incomplete and inaccurate, and the syntax ill-defined, poorly explained and unable to reflect complex subjects. In the nineties, the Subject Indexing Research Group (Gruppo di ricerca sull'indicizzazione per soggetto, GRIS) of the AIB (Italian Library Association) developed the indexing theory and some principles of PRECIS and drew up guidelines based on consistent principles for vocabulary, semantic relationships and subject string construction, the latter according to role syntax (Guida 1997). In overhauling the Soggettario, the National Library in Florence aimed at a comprehensive indexing system. (A report on the method and evolution of the work has been published in Knowledge Organization (Lucarelli 2005), while the feasibility study is available in Italian (Per un nuovo Soggettario 2002). Any usable terms from the old Soggettario will be transferred to the new system, while taking into consideration international norms and interlinguistic compatibility, as well as applications outside the immediate library context. The terms will be accessible via a suitable OPAC operating on the most advanced software.
The guide Nuovo soggettario was presented on February 8' 2007 at a one-day seminar in the Palazzo Vecchio, Florence, in front of some 500 spellbound people. The Nuovo soggettario comes in two parts: the guide in book-form and an accompanying CD-ROM, by way of which a prototype of the thesaurus may be accessed on the Internet. In the former, rules are stated; the latter contains a pdf version of the guide and the first installment of the controlled vocabulary, which is to be further enriched and refined. Syntactic instructions (general application guidelines, as well as special annotations of particular terms) and the compiled subject strings file have yet to be added. The essentials of the new system are: 1) an analytic-synthetic approach, 2) use of terms (units of controlled vocabulary) and subject strings (which represent subjects by combining terms in linear order to form syntactic relationships), instead of main headings and subdivisions, 3) specificity of terms and strings, with a view to the co-extension of subject string and subject matter and 4) a clear distinction between semantic and syntactic relationships, with full control of them both. Basic features of the vocabulary include the uniformity and univocality of terms and thesaural management of a priori (semantic) relationships. Starting from its definition, each term can be categorially analyzed: four macro-categories are represented (agents, action, things, time), for which there are subcategories called facets (e.g., for actions: activities, disciplines, processes), which in turn have sub-facets. Morphological instructions conform to national and international standards, including BS 8723, ANSI/ NISO Z39.19 and the IFLA draft of Guidelines for multilingual thesauri, even for syntactic factorization. Different kinds of semantic relationships are represented thoroughly, and particular attention is paid to poly-hierarchies, which are used only in moderation: both top terms must actually be relevant. Node labels are used to specify the principle of division applied. Instance relationships are also used.
An entry is structured so as to present all the essential elements of the indexing system. For each term are given: category, facet, related terms, Dewey interdisciplinary class number and, if necessary; definition or scope notes. Sources used are referenced (an appendix in the book lists those used in the current work). Historical notes indicate whenever a change of term has occurred, thus smoothing the transition from the old lists. In chapter 5, the longest one, detailed instructions with practical examples show how to create entries and how to relate terms; upper relationships must always be complete, right up to the top term, whereas hierarchies of related terms not yet fully developed may remain unfinished. Subject string construction consists in a double operation: analysis and synthesis. The former is the analysis of logical functions performed by single concepts in the definition of the subject (e.g., transitive actions, object, agent, etc.) or in syntactic relationships (transitive relationships and belonging relationship), so that each term for those concepts is assigned its role (e.g., key concept, transitive element, agent, instrument, etc.) in the subject string, where the core is distinct from the complementary roles (e.g., place, time, form, etc.). Synthesis is based on a scheme of nuclear and complementary roles, and citation order follows agreed-upon principles of one-to-one relationships and logical dependence. There is no standard citation order based on facets, in a categorial logic, but a flexible one, although thorough. For example, it is possible for a time term (subdivision) to precede an action term, when the former is related to the latter as the object of action: "Arazzi - Sec. 16.-17. - Restauro" [Tapestry - 16th-17th century - Restoration] (p. 126). So, even with more complex subjects, it is possible to produce perfectly readable strings covering the whole of the subject matter without splitting it into two incomplete and complementary headings. To this end, some unusual connectives are adopted, giving the strings a more discursive style.
Thesaurus software is based on AgroVoc (http:// www.fao.org/aims/ag_intro.htm) provided by the FAO, but in modified form. Many searching options and contextualization within the full hierarchies are possible, so that the choice of morphology and syntax of terms and strings is made easier by the complete overview of semantic relationships. New controlled terms will be available soon, thanks to the work in progress - there are now 13,000 terms, of which 40 percent are non-preferred. In three months, free Internet access by CD-ROM will cease and a subscription will be needed. The digital version of old Soggettario and the corresponding unstructured lists of headings adopted in 1956-1985 are accessible together with the thesaurus, so that the whole vocabulary, old and new, will be at the fingertips of the indexer, who is forced to work with both tools during this transition period. In the future, it will be possible to integrate the thesaurus into library OPACs. The two parts form a very consistent and detailed resource. The guide is filled with examples; the accurate, clearly-expressed and consistent instructions are further enhanced by good use of fonts and type size, facilitating reading. The thesaurus is simple and quick to use, very rich, albeit only a prototype; see, for instance, a list of DDC numbers and related terms with their category and facet, and then entries, hierarchies and so on, and the capacity of the structure to show organized knowledge. The excellent outcome of a demanding experimentation, the intended guide welcomes in a new era of subject indexing in Italy and is highly recommended. The new method has been designed to be easily teachable to new and experimented indexers.
Now BNI is beginning to use the new language, pointing the way for the adoption of Nuovo soggettario in Italian libraries: a difficult challenge whose success is not assured. To name only one issue: including all fields of study requires particular care in treating terms with different specialized meanings; cooperation of other libraries and institutions is foreseen. At the same time, efforts are being made to assure the system's interoperability outside the library world. It is clear that a great commitment is required. "Too complex a system!" say the naysayers. "Only at the beginning," the proponents reply. The new system goes against the mainstream, compared with the imitation of the easy way offered by search engines - but we know that they must enrich their devices to improve quality, just repeating the work on semantic and syntactic relationships that leads formal expressions to the meanings they are intended to communicate - and also compared with research to create automated devices supporting human work, for the need to simplify cataloguing. Here AI is not involved, but automation is widely used to facilitate and to support the conscious work of indexers guided by rules as clear as possible. The advantage of Nuovo soggettario is its combination of a thesaurus (a much-appreciated tool used across the world) with the equally widespread technique of subject-string construction, which is to say: the rational and predictable combination of the terms used. The appearance of this original, unparalleled working model may well be a great occasion in the international development of indexing, as, on one hand, the Nuovo soggettario uses a recognized tool (the thesaurus) and, on the other, by permitting both pre-coordination and post-coordination, it attempts to overcome the fragmentation of increasingly complex and specialized subjects into isolated, single-term descriptors. This is a serious proposition that merits consideration from both theoretical and practical points of view - and outside Italy, too."

Abstract

Using subject headings for Online Retrieval is an indispensable tool for online system desingners who are developing new systems or refining exicting ones. The book describes subject analysis and subject searching in online catalogs, including the limitations of retrieval, and demonstrates how such limitations can be overcome through system design and programming. The book describes the Library of Congress Subject headings system and system characteristics, shows how information is stored in machine readable files, and offers examples of and recommendations for successful methods. Tables are included to support these recommendations, and diagrams, graphs, and bar charts are used to provide results of data analyses.
