Abstract

Categories, or concepts of high generality representing the most basic kinds of entities in the world, have long been understood to be a fundamental element in the construction of knowledge organization systems (KOSs), particularly faceted ones. Commentators on facet analysis have tended to foreground the role of categories in the structuring of controlled vocabularies and the construction of compound index terms, and the implications of this for subject representation and information retrieval. Less attention has been paid to the variety of ways in which categories can shape the overall architectonic framework of a KOS. This case study explores the range of functions that categories took in structuring various aspects of an early analytico-synthetic KOS, Julius Otto Kaiser's method of Systematic Indexing (SI). Within SI, categories not only functioned as mechanisms to partition an index vocabulary into smaller groupings of terms and as elements in the construction of compound index terms but also served as means of defining the units of indexing, or index items, incorporated into an index; determining the organization of card index files and the articulation of the guide card system serving as a navigational aids thereto; and setting structural constraints to the establishment of cross-references between terms. In all these ways, Kaiser's system of categories contributed to the general systematicity of SI.

Abstract

Dieser Beitrag nimmt eine informationswissenschaftliche Perspektive ein und betrachtet das Phänomen der Klassifikation als Methode und System der Wissensorganisation. Ein Klassifikationssystem wird dabei als Wissensorganisationssystem (engl. knowledge organization system) verstanden, das vor allem im Bereich der Information und Dokumentation zum Einsatz kommt, um dokumentarische Bezugseinheiten (DBE) mit einem kontrollierten Vokabular zu beschreiben (s. Kapitel B 1 Einführung Wissensorganisation). Als eine solche Dokumentationssprache zeichnet sich ein Klassifikationssystem typischerweise durch seine systematische Ordnung aus und dient der inhaltlichen Groberschließung, eignet sich aber auch als Aufstellungssystematik und Hilfsmittel bei der Recherche wie etwa als systematischer Sucheinstieg oder thematischer Filter für Treffermengen. Beim Information Retrieval liegt die Stärke der klassifikatorischen Erschließung durch das hohe Abstraktionsniveau in Überblicks- und Vollständigkeitsrecherchen.

Abstract

In free classification, each concept is expressed by a constant notation, and classmarks are formed by free combinations of them, allowing the retrieval of records from a database by searching any of the component concepts. A refinement of free classification is freely faceted classification, where notation can include facets, expressing the kind of relations held between the concepts. The Integrative Level Classification project aims at testing free and freely faceted classification by applying them to small bibliographical samples in various domains. A sample, called the Dandelion Bibliography of Facet Analysis, is described here. Experience was gained using this system to classify 300 specialized papers dealing with facet analysis itself recorded on a MySQL database and building a Web interface exploiting freely faceted notation. The interface is written in PHP and uses string functions to process the queries and to yield relevant results selected and ordered according to the principles of integrative levels.

Abstract

The paper analyses the importance of data presentation and modelling and its role in improving the management, use and exchange of analytico-synthetic classifications in automated systems. Inefficiencies, in this respect, hinder the automation of classification systems that offer the possibility of building compound index/search terms. The lack of machine readable data expressing the semantics and structure of a classification vocabulary has negative effects on information management and retrieval, thus restricting the potential of both automated systems and classifications themselves. The authors analysed the data representation structure of three general analytico-synthetic classification systems (BC2-Bliss Bibliographic Classification; BSO-Broad System of Ordering; UDC-Universal Decimal Classification) and put forward some core requirements for classification data representation

Abstract

This article gives a cheerfully brief and undetailed account of how to make a faceted classification system, then describes information retrieval and searching on the web. It concludes by saying that facets would be excellent in helping users search and browse the web, but offers no real clues as to how this can be done.

Abstract

This volume deals with both theoretical and empirical research in classification and encompasses universal classification systems, special classification systems, thesauri and the place of classification in a broad spectrum of document and information systems. Papers fall into one or three major areas as follows: 1) general principles and policies 2) structure and logic in classification; and empirical investigation; classification in the design of various types of document/information systems. The papers originate from the ISCCR '91 conference and have been selected according to the following criteria: relevance to the conference theme; importance of the topic in the representation and organization of knowledge; quality; and originality in terms of potential contribution to research and new knowledge.

Abstract

This classic paper presents the reasoning behind the research undertaken by the Classification Research Group in London, beginning in 1952 and producing, by 1955, the direction in which the Group's efforts were to go in the next thirty years. The Group's original purpose was to review the basic principles of indexing and classification without committing itself to any existing system. It began by uncovering - among existing systems such as indexes, classifications, automatic selectors, and other information retrieval systems - the steps in the process by means of which a search was performed. The Group went over this very carefully, identifying parts of the process each step of the way. At the time this work was performed systems such as UNITERMS, which did not survive, and other alphabetical coordinated indexes, mainly experimental, were a dime a dozen. Classification to most librarians meant Dewey and the Library of Congress systems, both of which have very serious shortcomings from an intellectual point of view. The Group finally came to the conclusion that a classification of knowledge was necessary for constructing any successful retrieval system. The question then became one of deciding which kind of classification system. The members identified ten unsatisfactory features of existing systems. In fact, they could not find any general class schedule that either was satisfactory or could be made satisfactory. Obviously then, a new system had to be made. The question became one of how to do this. Existing theories did not conform to the theory of logical division; dividing and subdividing an the basis of a single characteristic was not followed. Thus logical division, which is a "top down" method of analysis, was rejected. Generic relationships would have to be made by some other methodology. A "bottom-up" or inductive, as opposed to deductive, method was a possibility. The Group actually decided to use a system in which a given genus could be subdivided in more than one way, thus "yielding a homogeneous group of collateral species."
The technique chosen was S. R. Ranganathan's facet analysis (q.v.). This method works from the bottom up: a term is categorized according to its parent class, as a kind, state, property, action, operation upon something, result of an Operation, agent, and so on. These modes of definition represent characteristics of division. Following the publication of this paper, the group worked for over ten years developing systems following this general pattern with various changes and experimental arrangements. Ranganathan's Colon Classification was the original of this type of method, but the Group rejected his contention that there are only five fundamental categories to be found in the knowledge base. They did, in fact, end up with varying numbers of categories in the experimental systems which they ultimately were to make. Notation was also recognized as a problem, being complex, illogical, lengthy, obscure and hard to understand. The Group tried to develop a rationale for notation, both as an ordering and as a finding device. To describe and represent a class, a notation could be long, but as a finding device, brevity would be preferable. The Group was to experiment with this aspect of classification and produce a number of interesting results. The Classification Research Group began meeting informally to discuss classification matters in 1952 and continues to meet, usually in London, to the present day. Most of the British authors whose work is presented in these pages have been members for most of the Group's life and continue in it. The Group maintains the basic position outlined in this paper to the present day. Its experimental approach has resulted in much more information about the nature and functions of classification systems. The ideal system has yet to be found. Classification research is still a promising area. The future calls for more experimentation based an reasoned approaches, following the example set by the Classification Research Group.

Abstract

Ranganathan's canons, principles, and postulates can easily confuse readers, especially because he revised and added to them in various editions of his many books. The Classification Research Group, who drew on Ranganathan's work as their basis for classification theory but developed it in their own way, has never clearly organized all their equivalent canons and principles. In this article Spiteri gathers the fundamental rules from both systems and compares and contrasts them. She makes her own clearer set of principles for constructing facets, stating the subject of a document, and designing notation. Spiteri's "simplified model" is clear and understandable, but certainly not simplistic. The model does not include methods for making a faceted system, but will serve as a very useful guide in how to turn initial work into a rigorous classification. Highly recommended

Abstract

Logic and the Organization of Information closely examines the historical and contemporary methodologies used to catalogue information objects-books, ebooks, journals, articles, web pages, images, emails, podcasts and more-in the digital era. This book provides an in-depth technical background for digital librarianship, and covers a broad range of theoretical and practical topics including: classification theory, topic annotation, automatic clustering, generalized synonymy and concept indexing, distributed libraries, semantic web ontologies and Simple Knowledge Organization System (SKOS). It also analyzes the challenges facing today's information architects, and outlines a series of techniques for overcoming them. Logic and the Organization of Information is intended for practitioners and professionals working at a design level as a reference book for digital librarianship. Advanced-level students, researchers and academics studying information science, library science, digital libraries and computer science will also find this book invaluable.

Footnote

Rez. in: J. Doc. 70(2014) no.4: "Books on the organization of information and knowledge, aimed at a library/information audience, tend to fall into two clear categories. Most are practical and pragmatic, explaining the "how" as much or more than the "why". Some are theoretical, in part or in whole, showing how the practice of classification, indexing, resource description and the like relates to philosophy, logic, and other foundational bases; the books by Langridge (1992) and by Svenonious (2000) are well-known examples this latter kind. To this category certainly belongs a recent book by Martin Frické (2012). The author takes the reader for an extended tour through a variety of aspects of information organization, including classification and taxonomy, alphabetical vocabularies and indexing, cataloguing and FRBR, and aspects of the semantic web. The emphasis throughout is on showing how practice is, or should be, underpinned by formal structures; there is a particular emphasis on first order predicate calculus. The advantages of a greater, and more explicit, use of symbolic logic is a recurring theme of the book. There is a particularly commendable historical dimension, often omitted in texts on this subject. It cannot be said that this book is entirely an easy read, although it is well written with a helpful index, and its arguments are generally well supported by clear and relevant examples. It is thorough and detailed, but thereby seems better geared to the needs of advanced students and researchers than to the practitioners who are suggested as a main market. For graduate students in library/information science and related disciplines, in particular, this will be a valuable resource. I would place it alongside Svenonious' book as the best insight into the theoretical "why" of information organization. It has evoked a good deal of interest, including a set of essay commentaries in Journal of Information Science (Gilchrist et al., 2013). Introducing these, Alan Gilchrist rightly says that Frické deserves a salute for making explicit the fundamental relationship between the ancient discipline of logic and modern information organization. If information science is to continue to develop, and make a contribution to the organization of the information environments of the future, then this book sets the groundwork for the kind of studies which will be needed."

Abstract

Classification is an activity that transcends time and space and that bridges the divisions between different languages and cultures, including the divisions between academic disciplines. Classificatory activity, however, serves different purposes in different situations. Classifications for infonnation retrieval can be called "professional" classifications and classifications in other fields can be called "naïve" classifications because they are developed by people who have no particular interest in classificatory issues. The general purpose of naïve classification systems is to discover new knowledge. In contrast, the general purpose of information retrieval classifications is to classify pre-existing knowledge. Different classificatory purposes may thus inform systems that are intended to span the cultural specifics of the globalized information society. This paper builds an previous research into the purposes and characteristics of naïve classifications. It describes some of the relationships between the purpose and context of a naive classification, the units of analysis used in it, and the theory that the context and the units of analysis imply.

Abstract

Argues that Beghtol's (2003) use of the terms "naive classification" and "professional classification" is valid because they are nominal definitions and that the distinction between these two types of classification points up the need for researchers in knowledge organization to broaden their scope beyond traditional classification systems intended for information retrieval. Argues that work by Beghtol (2003), Kwasnik (1999) and Bailey (1994) offer direction for the development of a classification of classifications based on the pragmatic dimensions of extant classification systems.

Abstract

For my segment of this program I'd like to focus on some basic qualities of classification schemes. These qualities are critical to our ability to truly organize knowledge for access. As I see it, there are at least five qualities of note. The first one of these properties that I want to talk about is "authoritative." By this I mean standardized, but I mean more than standardized with a built in consensus-building process. A classification scheme constructed by a collaborative, consensus-building process carries the approval, and the authority, of the discipline groups that contribute to it and that it affects... The next property of classification systems is "expandable," living, responsive, with a clear locus of responsibility for its continuous upkeep. The worst thing you can do with a thesaurus, or a classification scheme, is to finish it. You can't ever finish it because it reflects ongoing intellectual activity... The third property is "intuitive." That is, the system has to be approachable, it has to be transparent, or at least capable of being transparent. It has to have an underlying logic that supports the classification scheme but doesn't dominate it... The fourth property is "organized and logical." I advocate very strongly, and agree with Lois Chan, that classification must be based on a rule-based structure, on somebody's world-view of the syndetic structure... The fifth property is "universal" by which I mean the classification scheme needs be useable by any specific system or application, and be available as a language for multiple purposes.

Abstract

Networked orientated standards for vocabulary publishing and exchange and proposals for terminological services and terminology registries will improve sharing and use of all knowledge organization systems in the networked information environment. This means that documentary classifications may also become more applicable for use outside their original domain of application. The paper summarises some characteristics common to documentary classifications and explains some terminological, functional and implementation aspects. The original purpose behind each classification scheme determines the functions that the vocabulary is designed to facilitate. These functions influence the structure, semantics and syntax, scheme coverage and format in which classification data are published and made available. The author suggests that attention should be paid to the differences between documentary classifications as these may determine their suitability for a certain purpose and may impose different requirements with respect to their use online. As we speak, many classifications are being created for knowledge organization and it may be important to promote expertise from the bibliographic domain with respect to building and using classification systems.

Abstract

Brian C. Vickery, Director and Professor, School of Library, Archive and Information Studies, University College, London, is a prolific writer on classification and information retrieval. This paper was one of the earliest to present initial efforts by the Classification Research Group (q.v.). In it he clearly outlined the need for classification in subject indexing, which, at the time he wrote, was not a commonplace understanding. In fact, some indexing systems were made in the first place specifically to avoid general classification systems which were out of date in all fast-moving disciplines, especially in the "hard" sciences. Vickery picked up Julia Pettee's work (q.v.) an the concealed classification in subject headings (1947) and added to it, mainly adopting concepts from the work of S. R. Ranganathan (q.v.). He had already published a paper an notation in classification, pointing out connections between notation, words, and the concepts which they represent. He was especially concerned about the structure of notational symbols as such symbols represented relationships among subjects. Vickery also emphasized that index terms cover all aspects of a subject so that, in addition to having a basis in classification, the ideal index system should also have standardized nomenclature, as weIl as show evidence of a systematic classing of elementary terms. The necessary linkage between system and terms should be one of a number of methods, notably:

Abstract

Purpose - The purpose of this paper is to introduce a new similarity method to gauge the differences between two subject hierarchical structures. Design/methodology/approach - In the proposed similarity measure, nodes on two hierarchical structures are projected onto a two-dimensional space, respectively, and both structural similarity and subject similarity of nodes are considered in the similarity between the two hierarchical structures. The extent to which the structural similarity impacts on the similarity can be controlled by adjusting a parameter. An experiment was conducted to evaluate soundness of the measure. Eight experts whose research interests were information retrieval and information organization participated in the study. Results from the new measure were compared with results from the experts. Findings - The evaluation shows strong correlations between the results from the new method and the results from the experts. It suggests that the similarity method achieved satisfactory results. Practical implications - Hierarchical structures that are found in subject directories, taxonomies, classification systems, and other classificatory structures play an extremely important role in information organization and information representation. Measuring the similarity between two subject hierarchical structures allows an accurate overarching understanding of the degree to which the two hierarchical structures are similar. Originality/value - Both structural similarity and subject similarity of nodes were considered in the proposed similarity method, and the extent to which the structural similarity impacts on the similarity can be adjusted. In addition, a new evaluation method for a hierarchical structure similarity was presented.

Abstract

This is a classified, annotated bibliography about how to design faceted classification systems and make them usable on the World Wide Web. It is the first of three works I will be doing. The second, based on the material here and elsewhere, will discuss how to actually make the faceted system and put it online. The third will be a report of how I did just that, what worked, what didn't, and what I learned. Almost every article or book listed here begins with an explanation of what a faceted classification system is, so I won't (but see Steckel in Background below if you don't already know). They all agree that faceted systems are very appropriate for the web. Even pre-web articles (such as Duncan's in Background, below) assert that hypertext and facets will go together well. Combined, it is possible to take a set of documents and classify them or apply subject headings to describe what they are about, then build a navigational structure so that any user, no matter how he or she approaches the material, no matter what his or her goals, can move and search in a way that makes sense to them, but still get to the same useful results as someone else following a different path to the same goal. There is no one way that everyone will always use when looking for information. The more flexible the organization of the information, the more accommodating it is. Facets are more flexible for hypertext browsing than any enumerative or hierarchical system.
Consider movie listings in newspapers. Most Canadian newspapers list movie showtimes in two large blocks, for the two major theatre chains. The listings are ordered by region (in large cities), then theatre, then movie, and finally by showtime. Anyone wondering where and when a particular movie is playing must scan the complete listings. Determining what movies are playing in the next half hour is very difficult. When movie listings went onto the web, most sites used a simple faceted organization, always with movie name and theatre, and perhaps with region or neighbourhood (thankfully, theatre chains were left out). They make it easy to pick a theatre and see what movies are playing there, or to pick a movie and see what theatres are showing it. To complete the system, the sites should allow users to browse by neighbourhood and showtime, and to order the results in any way they desired. Thus could people easily find answers to such questions as, "Where is the new James Bond movie playing?" "What's showing at the Roxy tonight?" "I'm going to be out in in Little Finland this afternoon with three hours to kill starting at 2 ... is anything interesting playing?" A hypertext, faceted classification system makes more useful information more easily available to the user. Reading the books and articles below in chronological order will show a certain progression: suggestions that faceting and hypertext might work well, confidence that facets would work well if only someone would make such a system, and finally the beginning of serious work on actually designing, building, and testing faceted web sites. There is a solid basis of how to make faceted classifications (see Vickery in Recommended), but their application online is just starting. Work on XFML (see Van Dijck's work in Recommended) the Exchangeable Faceted Metadata Language, will make this easier. If it follows previous patterns, parts of the Internet community will embrace the idea and make open source software available for others to reuse. It will be particularly beneficial if professionals in both information studies and computer science can work together to build working systems, standards, and code. Each can benefit from the other's expertise in what can be a very complicated and technical area. One particularly nice thing about this area of research is that people interested in combining facets and the web often have web sites where they post their writings.
This bibliography is not meant to be exhaustive, but unfortunately it is not as complete as I wanted. Some books and articles are not be included, but they may be used in my future work. (These include two books and one article by B.C. Vickery: Faceted Classification Schemes (New Brunswick, NJ: Rutgers, 1966), Classification and Indexing in Science, 3rd ed. (London: Butterworths, 1975), and "Knowledge Representation: A Brief Review" (Journal of Documentation 42 no. 3 (September 1986): 145-159; and A.C. Foskett's "The Future of Faceted Classification" in The Future of Classification, edited by Rita Marcella and Arthur Maltby (Aldershot, England: Gower, 2000): 69-80). Nevertheless, I hope this bibliography will be useful for those both new to or familiar with faceted hypertext systems. Some very basic resources are listed, as well as some very advanced ones. Some example web sites are mentioned, but there is no detailed technical discussion of any software. The user interface to any web site is extremely important, and this is briefly mentioned in two or three places (for example the discussion of lawforwa.org (see Example Web Sites)). The larger question of how to display information graphically and with hypertext is outside the scope of this bibliography. There are five sections: Recommended, Background, Not Relevant, Example Web Sites, and Mailing Lists. Background material is either introductory, advanced, or of peripheral interest, and can be read after the Recommended resources if the reader wants to know more. The Not Relevant category contains articles that may appear in bibliographies but are not relevant for my purposes.
