Subject Indexing

PurposeTraditional subject indexing and classification are considered infeasible in many digital collections. This paper seeks to investigate ways of enhancing social tagging via knowledge organization systems, with a view to improving the quality of tags for increased information discovery and retrieval performance.Design/methodology/approachEnhanced tagging interfaces were developed for exemplar online repositories, and trials were undertaken with author and reader groups to evaluate the effectiveness of tagging augmented with control vocabulary for subject indexing of papers in online repositories.FindingsThe results showed that using a knowledge organisation system to augment tagging does appear to increase the effectiveness of non‐specialist users (that is, without information science training) in subject indexing.Research limitations/implicationsWhile limited by the size and scope of the trials undertaken, these results do point to the usefulness of a mixed approach in supporting the subject indexing of online resources.Originality/valueThe value of this work is as a guide to future developments in the practical support for resource indexing in online repositories.

The World

One of the most important tasks of a librarian is the assignment of appropriate subject(s) to a resource within a library’s collection. The subjects usually belong to a controlled vocabulary that is specifically designed for such a task. The most widely adopted controlled vocabulary across libraries around the world is the Library of Congress Subject Headings (LCSH). However, there seems to be a shifting from traditional LCSH to modern thesauri. In this paper, a methodology is proposed, capable of incorporating thesauri into existing LCSH-based Information Retrieval–IR systems. In order to achieve this, a mapping methodology is proposed capable of providing a common structure consisting of terms belonging to LCSH and/or a thesaurus. The structure is modeled as a Simple Knowledge Organization System (SKOS) ontology, which can be employed by appropriate subject-based IR systems. As a proof of concept, the proposed methodology is applied to the DSpace-based University of Piraeus digital library.

RESUMO A retórica acerca da necessidade de se explorar ferramentas que contribuam para o crescimento ordenado da Web pelo prisma das transformações que o avanço tecnológico tem causado na sociedade é cada vez mais substancial. Sendo assim, métodos de organização da informação são de expressiva importância para garantir não apenas a recuperação da mesma, mas igualmente promover a transposição das fronteiras culturais e geográficas de acesso à informação. Nesse cenário, ressaltam-se os Sistemas de Organização do Conhecimento (Knowledge Organization Systems) como ferramentas que englobam todos os tipos de esquemas que visam promover a gestão do conhecimento, como esquemas de classificação, cabeçalhos de assunto, tesauros, ontologias, entre outros. Em 2009, a Word Wide Web Consortium apresentou o SKOS - Simple Knowledge Organization System como um modelo que tem se destacado na padronização de recursos informacionais na Web, pois fornece uma maneira de representar os Sistemas de Organização do Conhecimento tradicionais permitindo que eles sejam legíveis por máquinas. Considerando a crescente tendência de elaboração de tesauros para utilização em ambientes digitais, destacamos o Tesauro Brasileiro de Ciência da Informação, publicado em 2014 pelo Instituto Brasileiro de Informação em Ciência e Tecnologia, como instrumento fundamental para recuperar e acessar informações com precisão. Sem dúvidas, sua transposição para a Web representa ainda mais um avanço para a área de Biblioteconomia e Ciência da Informação. Portanto, o presente trabalho se dedica à avaliação da conversão da categoria “Informação e Conhecimento Estratégicos nas Organizações” do Tesauro Brasileiro de Ciência da Informação em um microtesauro em SKOS. Trata-se de uma pesquisa de cunho teórico e metodológico que se propõe a abordar os temas de representação, organização e disponibilização de vocabulários em ambientes digitais. Caracteriza-se, também, como pesquisa de natureza aplicada e exploratória uma vez que objetiva gerar conhecimentos para aplicação prática. O presente estudo evidenciou que o SKOS se apresenta como uma opção de baixo custo, favorece maior interoperabilidade entre vocabulários a partir da integração de diferentes conjuntos de dados e tem expressiva contribuição para o aperfeiçoamento das tradicionais ferramentas de recuperação da informação.

AGROVOC is the multilingual thesaurus managed and published by the Food and Agriculture Organization of the United Nations (FAO). Its content is available in more than 40 languages and covers all the FAO’s areas of interest. The structural basis is a resource description framework (RDF) and simple knowledge organization system (SKOS). More than 39,000 concepts identified by a uniform resource identifier (URI) and 800,000 terms are related through a hierarchical system and aligned to knowledge organization systems. This paper aims to illustrate the recent developments in the context of AGROVOC and to present use cases where it has contributed to enhancing the interoperability of data shared by different information systems.

PURPOSE/THESIS: This paper discusses the challenges of creating a theoretic framework within the context of an intercultural and ethically responsible knowledge organization system (KOS). APPROACH/METHODS: First, the paper explores ethical and societal concerns linked to the development of KOS. Second, it illustrates a way to tackle this ethical factor by proposing an applicable architecture for intercultural interfaces which respects cultural diversity on a global scale. RESULTS AND CONCLUSIONS: The author emphasizes the importance of opening up the notion of cultural inclusiveness, to weigh not only linguistic diversity but also other cultural and social aspects, such as geography, religious affiliations, tradition, historical elements, ethnic. This kind of approach should be attentive to intersectionality and cultural interoperability. ORIGINALITY/VALUE: By addressing local circumstances, the author offers insights into essential approaches that take into account cultural diversity when designing KOS and access interfaces to knowledge.

Ontological Model

In his Categories, Aristotle details the kinds of being that exist, along with what can be understood and predicated of existing things. Most notably within this work, Aristotle advances a set of ten, top-level categories that can be used to classify all kinds of being. Even today, the influence of the Categories is felt in many domains, particularly in knowledge organization (KO). Here, Aristotle’s Categories bear deep, long-standing connections with works examining categorization, subject analysis, and theory of classification. Though its relation to ontology might seem obvious, connections to KO perspectives on knowledge organization systems (KOSs) and ontological modeling are curiously lacking. The aim of this work is to offer a re-examination of the Categories as a KOS, particularly through the lens of the KO field’s understandings of ontology. Utilizing Zeng’s classification of KOSs as a theoretical framework, this study draws parallels between the first two sections of the Categories and the defining features of ontologies and offers an initial ontological model of this work. The results of this re-examination stand to offer a new view of a fundamental work in the KO canon, draw further connections between past and present perspectives in KO, and further contribute to the theoretical grounding of contemporary KOS research and practice.

Knowledge Organization Systems

The knowledge organization systems (KOS) in use at libraries are social constructs that were conceived in the Euro-American context to organize and retrieve Western knowledge materials. As social constructs of the West, the effectiveness of library KOSs is limited when it comes to organization and retrieval of non-Western knowledge materials. How can librarians respond if asked to make non-Western knowledge materials as accessible as Western materials in their libraries? The accessibility of Western and non-Western knowledge materials in libraries need not be an either-or proposition. By way of a case study, a practical way forward is presented by which librarians can use their professional agency and existing digital technologies to exercise social justice. More specifically I demonstrate the design and development of a specialized KOS that enriches digital collections with hypertext features to enhance the accessibility of non-Western knowledge materials in libraries.

RESUMO Considerando que os aportes que subsidiam teoricamente os sistemas de organização do conhecimento normalmente se amparam em perspectivas que consolidam visões estruturalistas, a fim de controlar e formalizar representações do conhecimento, ensaiamos neste artigo um possível limiar para organização e representação do conhecimento, baseado nos conceitos de devir e de rizoma definidos pelos filósofos Gilles Deleuze e Félix Guattari. Tendo como horizonte a ideia de contemporaneidade de Giorgio Agamben, buscamos valorizar a potência dos devires e a intempestividade dos rizomas em prol de uma organização do conhecimento menos previsível e menos determinista. Alicerçado por um exercício de reflexão teórica, concluímos em defesa da realização de rizomas em oposição aos instrumentos já conhecidos e/ou praticados pela organização do conhecimento.Palavras-chave: Organização do Conhecimento; Representação do Conhecimento; Rizoma; Devir; Sistemas de Organização do Conhecimento.ABSTRACT Considering that the theoretical contributions that support knowledge organization systems usually rely on perspectives that consolidate structuralist approaches, to control and formalize knowledge representations, we elaborate in this article a possible opening for a knowledge organization and representation based on the concepts of becoming and rhizome developed by Gilles Deleuze and Félix Guattari. Based on the idea of contemporaneity by Giorgio Agamben, we seek to value the power of the becoming and the intempestivity of rhizomes in favor of a less predictable and deterministic knowledge organization. Supported by an exercise of theoretical reflection, we conclude in favor of rhizomes as opposed to systems already known and/or practiced in knowledge organization field.Keywords: Knowledge Organization; Knowledge Representation; Rhizome; Becoming; Knowledge Organization System.
