Abstract

Basic grammar can achieve most/all of the goals of facet analysis without requiring the use of facet indicators. Facet analysis is thus rendered far simpler for classificationist, classifier, and user. We compare facet analysis and grammar, and show how various facets can be represented grammatically. We then address potential challenges in employing grammar as subject classification. A detailed review of basic grammar supports the hypothesis that it is feasible to usefully employ grammatical construction in subject classification. A manageable - and programmable - set of adjustments is required as classifiers move fairly directly from sentences in a document (or object or idea) description to formulating a subject classification. The user likewise can move fairly quickly from a query to the identification of relevant works. A review of theories in linguistics indicates that a grammatical approach should reduce ambiguity while encouraging ease of use. This paper applies the recommended approach to a small sample of recently published books. It finds that the approach is feasible and results in a more precise subject description than the subject headings assigned at present. It then explores PRECIS, an indexing system developed in the 1970s. Though our approach differs from PRECIS in many important ways, the experience of PRECIS supports our conclusions regarding both feasibility and precision.

Abstract

In the early years of the 20th century, Julius Otto Kaiser (1868-1927), a special librarian and indexer of technical literature, developed a method of knowledge organization (KO) known as systematic indexing. Certain elements of the method-its stipulation that all indexing terms be divided into fundamental categories "concretes", "countries", and "processes", which are then to be synthesized into indexing "statements" formulated according to strict rules of citation order-have long been recognized as precursors to key principles of the theory of faceted classification. However, other, less well-known elements of the method may prove no less interesting to practitioners of KO. In particular, two aspects of systematic indexing seem to prefigure current trends in KO: (1) a perspectivist outlook that rejects universal classifications in favor of information organization systems customized to reflect local needs and (2) the incorporation of index terms extracted from source documents into a polyhierarchical taxonomical structure. Kaiser's perspectivism anticipates postmodern theories of KO, while his principled use of polyhierarchy to organize terms derived from the language of source documents provides a potentially fruitful model that can inform current discussions about harvesting natural-language terms, such as tags, and incorporating them into a flexibly structured controlled vocabulary.

Abstract

Division is obviously important to Knowledge Organization. Typically, an organizational infrastructure might acknowledge three types of connecting relationships: class hierarchies, where some classes are subclasses of others, partitive hierarchies, where some items are parts of others, and instantiation, where some items are members of some classes (see Z39.19 ANSI/NISO 2005 as an example). The first two of these involve division (the third, instantiation, does not involve division). Logical division would usually be a part of hierarchical classification systems, which, in turn, are central to shelving in libraries, to subject classification schemes, to controlled vocabularies, and to thesauri. Partitive hierarchies, and partitive division, are often essential to controlled vocabularies, thesauri, and subject tagging systems. Partitive hierarchies also relate to the bearers of information; for example, a journal would typically have its component articles as parts and, in turn, they might have sections as their parts, and, of course, components might be arrived at by partitive division (see Tillett 2009 as an illustration). Finally, verbal division, disambiguating homographs, is basic to controlled vocabularies. Thus Division is a broad and relevant topic. This article, though, is going to focus on Logical Division.

Abstract

Vanda, lecturer at SLAIS and ISKOUK Chairperson, provided an account of the origins of faceted classification in the work of the eminent Indian scholar and librarian S. R. Ranganathan in the 1930s and described how its influence persists today. Ranganathan himself derived inspiration for his Colon Classification from Meccano, which he came across in a London toy shop whilst studying at UCL in 1924. Vanda, on the other hand, proposed that the molecular model is perhaps a better representation

Abstract

Integrative level classification (ILC) is a research project being developed since 2004 by some members of the Italian chapter of ISKO, also involving cooperation with other researchers. Anyone interested is welcome to contact us at: ilc@mate.unipv.it. Aim of the project is to test application of the theory of integrative levels to knowledge organization (KO). This implies a naturalistic-ontological approach to KO, which is obviously not the only possible approach - actually it even looks to be unfashionable nowadays, although it agrees with current trends towards interdisciplinarity and interrelation between many research fields.

Abstract

Claudio Gnoli of the University of Pavia in Italy and Chair of ISKO Italy, explored the relative merits of classic 'faceted classification' (FC) and 'freely faceted classification' (FFC). In classic FC, the facets (and their relationships) which might be combined to express a compound subject, are restricted to those prescribed as inherent in the subject area. FC is therefore largely bounded by and restricted to a specific subject area. At the other extreme, free classification (as in the Web or folksonomies) allows the combination of values from multiple, disparate domains where the relationships among the elements are often indeterminate, and the semantics obscure. Claudio described how punched cards were an early example of free classification, and cited the coordination of dogs : postmen : bites as one where the absence of defined relationships made the semantics ambiguous

Abstract

Faceted analytical theory is a widely accepted approach for constructing modern classification schemes and other controlled vocabularies. While the advantages of faceted approach are broadly accepted and understood the actual implementation is coupled with many challenges when it comes to data modelling, management and retrieval. UDC Seminar 2017 revisits faceted analytical theory as one of the most influential methodologies in the development of knowledge organization systems.
