Abstract

The spread of many new media and formats is changing the scenario faced by knowledge organizers: as printed monographs are not the only standard form of knowledge carrier anymore, the traditional kind of knowledge organization (KO) systems based on academic disciplines is put into question. A sounder foundation can be provided by an analysis of the different dimensions concurring to form the content of any knowledge item-what Brian Vickery described as the steps "from the world to the classifier." The ultimate referents of documents are the phenomena of the real world, that can be ordered by ontology, the study of what exists. Phenomena coexist in subjects with the perspectives by which they are considered, pertaining to epistemology, and with the formal features of knowledge carriers, adding a further, pragmatic layer. All these dimensions can be accounted for in metadata, but are often done so in mixed ways, making indexes less rigorous and interoperable. For example, while facet analysis was originally developed for subject indexing, many "faceted" interfaces today mix subject facets with form facets, and schemes presented as "ontologies" for the "semantic Web" also code for non-semantic information. In bibliographic classifications, phenomena are often confused with the disciplines dealing with them, the latter being assumed to be the most useful starting point, for users will have either one or another perspective. A general citation order of dimensions- phenomena, perspective, carrier-is recommended, helping to concentrate most relevant information at the beginning of headings.

Abstract

Purpose - The purpose of this paper is to find a relationship between traditional faceted classification schemes and semantic web document annotators, particularly in the linked data environment. Design/methodology/approach - A consideration of the conceptual ideas behind faceted classification and linked data architecture is made. Analysis of selected web documents is performed using Calais' Semantic Proxy to support the considerations. Findings - Technical language aside, the principles of both approaches are very similar. Modern classification techniques have the potential to automatically generate metadata to drive more precise information recall by including a semantic layer. Originality/value - Linked data have not been explicitly considered in this context before in the published literature.

Abstract

Purpose - Classification is an important process in making sense of the world, and has a pronounced social dimension. This paper aims to compare folksonomy, a new social classification system currently being developed on the web, with conventional taxonomy in the light of theoretical sociological and anthropological approaches. The co-existence of these two types of classification system raises the questions: Will and should taxonomies be hybridized with folksonomies? What can each of these systems contribute to information-searching processes, and how can the sociology of knowledge provide an answer to these questions? This paper aims also to address these issues. Design/methodology/approach - This paper is situated at the meeting point of the sociology of knowledge, epistemology and information science and aims at examining systems of classification in the light of both classical theory and current late-modern sociological and anthropological approaches. Findings - Using theoretical approaches current in the sociology of science and knowledge, the paper envisages two divergent possible outcomes. Originality/value - While concentrating on classifications systems, this paper addresses the more general social issue of what we know and how it is known. The concept of hybrid knowledge is suggested in order to illuminate the epistemological basis of late-modern knowledge being constructed by hybridizing contradictory modern knowledge categories, such as the subjective with the objective and the social with the natural. Integrating tree-like taxonomies with folksonomies or, in other words, generating a naturalized structural order of objective relations with social, subjective classification systems, can create a vast range of hybrid knowledge.

Abstract

This paper looks at Simple Knowledge Organization System (SKOS) to investigate how a faceted classification can be expressed in RDF and shared on the Semantic Web. Statement of the Problem Faceted classification outlines facets as well as subfacets and facet values. Hierarchical relationships and associative relationships are established in a faceted classification. RDF is used to describe how a specific URI has a relationship to a facet value. Not only does RDF decompose "information into pieces," but by incorporating facet values RDF also given the URI the hierarchical and associative relationships expressed in the faceted classification. Combining faceted classification and RDF creates more knowledge than if the two stood alone. An application understands the subjectpredicate-object relationship in RDF and can display hierarchical and associative relationships based on the object (facet) value. This paper continues to investigate if the above idea is indeed useful, used, and applicable. If so, how can a faceted classification be expressed in RDF? What would this expression look like? Literature Review This paper used the same articles as the paper A Survey of Faceted Classification: History, Uses, Drawbacks and the Semantic Web (Putkey, 2010). In that paper, appropriate resources were discovered by searching in various databases for "faceted classification" and "faceted search," either in the descriptor or title fields. Citations were also followed to find more articles as well as searching the Internet for the same terms. To retrieve the documents about RDF, searches combined "faceted classification" and "RDF, " looking for these words in either the descriptor or title.
Methodology Based on information from research papers, more research was done on SKOS and examples of SKOS and shared faceted classifications in the Semantic Web and about SKOS and how to express SKOS in RDF/XML. Once confident with these ideas, the author used a faceted taxonomy created in a Vocabulary Design class and encoded it using SKOS. Instead of writing RDF in a program such as Notepad, a thesaurus tool was used to create the taxonomy according to SKOS standards and then export the thesaurus in RDF/XML format. These processes and tools are then analyzed. Results The initial statement of the problem was simply an extension of the survey paper done earlier in this class. To continue on with the research, more research was done into SKOS - a standard for expressing thesauri, taxonomies and faceted classifications so they can be shared on the semantic web.

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

The Library of Congress is a federal institution that occupies a critical space where medical, social science, political, literary, and other discourses are collected, arranged, and disseminated to Congress and the public. LC plays a vital part in discipline creation and maintenance, as it actively reproduces specific discourses, while silencing others, such as those from the humanities, social sciences, and the general public. Alternatively, social tagging seems to disregard conventions of disciplinarity and allows much more diversity of representations. Tagging may provide important insight for organizing materials in research libraries, as choices between single disciplines are no longer necessary and voices from various fields and audiences can name resources using their own terms, whether they prefer medical/technical jargon or everyday words. As the academy moves more toward interdisciplinary/transdisciplinary studies and aims to find the intersections across political, social, scientific, and cultural phenomena, the implications and effects of library organization based on classes and subjects needs to be interrogated.

Abstract

The identification and contextual definition of concepts is the core of knowledge organization. The full expression of comprehension is accomplished through the use of an extension device called the facet. A facet is a category of dimensional characteristics that cross the hierarchical array of concepts to provide extension, or breadth, to the contexts in which they are discovered or expressed in knowledge organization systems. The use of the facet in knowledge organization has a rich history arising in the mid-nineteenth century. As it has matured through more than a century of application, the notion of the facet in knowledge organization has taken on a variety of meanings, from that of simple categories used in web search engines to the more sophisticated idea of intersecting dimensions of knowledge. This book describes the state of the art of the understanding of facets in knowledge organization today.

Abstract

Previously, the main problem of information extraction was to gather enough data. Today, the challenge is not to collect data but to interpret and represent them in order to deduce information. Ontologies are considered suitable solutions for organizing information. The classic methods for ontology construction from textual documents rely on natural language analysis and are generally based on statistical or linguistic approaches. However, these approaches do not consider the document structure which provides additional knowledge. In fact, the structural organization of documents also conveys meaning. In this context, new approaches focus on document structure analysis to extract knowledge. This paper describes a methodology for ontology construction from web data and especially from Wikipedia articles. It focuses mainly on document structure in order to extract the main concepts and their relations. The proposed methods extract not only taxonomic and non-taxonomic relations but also give the labels describing non-taxonomic relations. The extraction of non-taxonomic relations is established by analyzing the titles hierarchy in each document. A pattern matching is also applied in order to extract known semantic relations. We propose also to apply a refinement to the extracted relations in order to keep only those that are relevant. The refinement process is performed by applying the transitive property, checking the nature of the relations and analyzing taxonomic relations having inverted arguments. Experiments have been performed on French Wikipedia articles related to the medical field. Ontology evaluation is performed by comparing it to gold standards.

Abstract

Shiyali Ramamrita Ranganathan's theory of classification spans a number of works over a number of decades. And while he was devoted to solving many problems in the practice of librarianship, and is known as the father of library science in India (Garfield, 1984), his work in classification revolves around one central concern. His classification research addressed the problems that arose from introducing new ideas into a scheme for classification, while maintaining a meaningful hierarchical and systematically arranged order of classes. This is because hierarchical and systematically arranged classes are the defining characteristic of useful classification. To lose this order is to through the addition of new classes is to introduce confusion, if not chaos, and to move toward a useless classification - or at least one that requires complete revision. In the following chapter, I outline the stages, and the elements of those stages, in Ranganathan's thought on classification from 1926-1972, as well as posthumous work that continues his agenda. And while facets figure prominently in all of these stages; but for Ranganathan to achieve his goal, he must continually add to this central feature of his theory of classification. I will close this chapter with an outline of persistent problems that represent research fronts for the field. Chief among these are what to do about scheme change and the open question about the rigor of information modeling in light of semantic web developments.

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

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

Any classification system should be evaluated with respect to a variety of philosophical and practical concerns. This paper explores several distinct issues: the nature of a work, the value of a statement, the contribution of information science to philosophy, the nature of hierarchy, ethical evaluation, pre- versus postcoordination, the lived experience of librarians, and formalization versus natural language. It evaluates a particular approach to classification in terms of each of these but draws general lessons for philosophical evaluation. That approach to classification emphasizes the free combination of basic concepts representing both real things in the world and the relationships among these; works are also classified in terms of theories, methods, and perspectives applied.

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.
