Prejudice but no pride: The Portuguese Universal Decimal Classification’s labelling of sexual orientation

Critical cataloguing aims to study cases of social injustice, misrepresentation, negative biases, offensive terminologies, and hegemonic and oppressive hierarchical structures in the representation of communities and identities in knowledge organization systems. The aim of this study is to provide a critical analysis of the representation of sexual orientation in the Portuguese Universal Decimal Classification, grounded in a qualitative content analysis method. The results show that the principle of exhaustiveness does not manifest itself in the representation of sexual orientation. The absence of the term ‘heterosexuality’ mirrors the heteronormative hegemony, while the minoritization of ‘lesbianism’, but not of ‘male homosexuality’, reflects the patriarchal hegemony. The representation of sexual orientation carries the historical pathologization of sexual orientations other than heterosexuality. The Portuguese Universal Decimal Classification conveys negative biases and misrepresents sexual orientation in a way that is irreconcilable with present-day reality. Critical thinking must be encouraged within the library community and the Universal Decimal Classification should be promptly revised and updated.

Interdisciplinary Knowledge in Library and Bibliographic Classification and Universal Decimal Classification

Library classification was originally created for the purpose of thematic arrangement of books on the shelves in libraries on the basis of classification systems. The creation of the latter, in turn, is closely related to the classification of sciences, as works devoted to certain fields of knowledge or spheres of human activity are classified.Throughout their history, classification schemes have been transformed and structurally changed, based on the basic principles and levels of scientific knowledge. Originating in the ancient period, science has been developing for centuries according to the disciplinary principle. However, in the process of evolution of scientific knowledge there is interdisciplinary integration, which involves both natural, technical and social sciences. Complex fields of study are formed as a result of interscientific interaction, when the most distant sciences can discover a direct connection. This is a joint cognitive activity of specialists from different scientific disciplines, involving not only research, but also other types of activity (organizational, communicative, journalistic, etc.). Thus, the sphere of interdisciplinarity is formed.The article considers the representation of the problems of interdisciplinary research in the Universal Decimal Classification (UDC) and in the Library and Bibliographic Classification (LBC), recognized as the national classification system of Russia.

Subject Analysis of Component Parts of Serials and Books in the National Library of Serbia

Creating bibliographies (from the 17th century to modern times) is a way of describing books and other types of publications and classifying them according to certain standards, with the aim of providing sufficient information about a certain work. Since the end of the Second World War, with the increase in the number of publications on the territory of the newly formed state, there was a need to create a unique database of bibliographies of publications, in order to provide users with insight into the entire publishing activity of Yugoslavia. This work continued even after the independence of the Republic of Serbia, in the National Library of Serbia (NLS). In addition to creating bibliographies of monographic and serial publications, the NLS also creates bibliographies of articles and content from professional journals. The Department of Serial Publications, more precisely the Subject Analysis Subdepartment, is in charge of this work as a separate organizational unit. Within this department, in addition to the creation of bibliographies, bibliographies of articles from proceedings, CIP of articles (professional classification of articles from serial publications of articles), revision of the library collection, and translation of UDC (Universal Decimal Classification) tables are carried out.

Developing the system of interconnected classifications: Comparing the State Rubricator of Sci-tech Information and Universal Decimal Classification

The authors discuss the findings of the study to compare relevant master versions of the State Rubricator of Sci-tech Information and Universal Decimal Classification (UDC) in Russian. The classifications are compared through the method of intellectual analysis of intrinsic and semantic characteristics of SRSTI subject headings and UDC main schedules and its general and special subdivision tables. The UDC compound numbers are assigned to over the half of all rubrication vertexes. Over one third of SRSTI headings are assigned the compound UDC numbers made of two+ simple or compound numbers. The semantic matches between SRSTI headings and assigned UDC numbers are established as logical match, inclusion or extension overlapping with provision for terminological, structural and semantic features of the classifications being compared, as well as of the substance of the subject areas and their indexing principles. The interreflection of SRSTI and UDC numbers is executed in three types of relations: equivalence, hierarchy, association. Based on the analysis of coefficients of distribution by types of relations between semantic SRSTI headings and UDC numbers, the conclusion is made on the relatively high matching of terminology and structure of the given classification systems in almost every thematic class of subject areas. The value of the study is that the “converter” between SRSTI and UDC is to expand functionality of the interrelated classifications.Russian National Public Library for Science and Technology, within the framework of the Government Order No. 075-01235-23-01, R&D theme No. 1021070112681-2-1.2.1;5.8.3, has been pursuing research for building the single network of links between classifications, development of “converters” between them for the purpose of computer-aided thematic systematization, and integration of dispersed information resources. The State Rubricator of Scientific and Technical Information (SRSTI) is the core classification of the unified networked classification links.

Automated Subject Identification using the Universal Decimal Classification: The ANN Approach

Universal Decimal Classification (UDC) is a popular controlled vocabulary that is used to represent subjects of documents. Text categorization determines a text's category, as evident from the notation-text label format of the Universal Decimal Classification. With the help of machine learning techniques and the Universal Decimal Classification (UDC), the present work aims to develop an end-user (library professional) based recommender system for automatically classifying documents using the UDC scheme. The proposed work is conceived for determining and constructing a complex class number using the syntax of Universal Decimal Classification (UDC). A corpus of documents classified with the UDC scheme is used as a training dataset. The classification of the documents is done with human mediation having proficiency in classificatory approaches. The BERT model and the KNIME software are used for the study. This study uses the classified dataset to fine-tune the pre-trained BERT model to construct the semi-automatic classification model. The results show that the model is constructed with high accuracy and Area Under Curve (AUC) value, although the prediction represented a low accuracy rate. This study reflected that if the model is explicitly trained by annotating each concept and if the full licensed version of UDC class numbers becomes available, there is a greater potency of developing an automated, freely faceted classification scheme for practical use.

The Universal Decimal Classification in the Organization of Knowledge: Representing the Concept of Ethics

Training in knowl­edge organization (KO) involves an understanding of theories for the construction, maintenance, use, and evaluation of logical documentary languages. Teaching these KO concepts in LIS programs are related basically to accessing documents and retrieving their intellectual content. This study focuses on access to documents and exploring the ethical theme in all its dimensions as applied to the teaching of an undergraduate discipline as part of a Bachelor of Library Science degree offered at the Federal University of Minas Gerais (UFMG). As a methodology, a Project-based Pedagogy strategy is used in the teaching of a discipline called “Classification Systems: UDC” for students to classify a documentary resource from a collection on ethics. The teaching of bibliographic classification requires students to learn how to use the mechanisms available to form a notation as well as to use a syntax schema (tables) appropriately. Students also learn to determine a place for the document in the collection, considering the knowl­edge represented in the collection as a whole. Altogether, such a practice can help students to understand the theory underlying a classification system. The results show that the students were able to understand the basic concepts of knowl­edge organization. The students were also able to observe that the elements of the different tables of a classification tool are essential mechanisms for the organization of knowl­edge in other contexts, especially for specific purposes.

КОНЦЕПТУАЛЬНАЯ КЛАССИФИКАЦИОННАЯ МОДЕЛЬ ЗНАНИЙ КАК СПОСОБ СОВЕРШЕНСТВОВАНИЯ УНИВЕРСАЛЬНОЙ ДЕСЯТИЧНОЙ КЛАССИФИКАЦИИ

The article deals with the urgent task of improving the universal decimal classification (UDC) in connection with its numerous shortcomings. The examples given in the article show that the well-known rules for constructing classifications are violated in the UDC and the system principles for constructing classification models are not applied. These circumstances turn UDC indexing into a complex and extremely time-consuming creative, heuristic process, the result of which in many cases, in principle, cannot be correct. To solve the problem, a systematic approach to the construction of conceptual classification models (CCM) was applied, which allows representing a conceptual (conceptual) model of the form and content of knowledge, which will ensure the ease of its perception, memorization and use, as well as the uniqueness of solving the problem of choosing a document index on the content and form of information. The basic classification of knowledge and the classification of knowledge by content and form are presented, on the basis of which classifiers of specific subject areas can be developed.

«…YOUR OPINION IS INTERESTING…, AS THE OPINION OF A TRUE SCIENTIST»: EPISTOLS B. S. BODNARSKY TO S. I.-Y. BOROVOY

The article presents the part of the epistolary heritage of the outstanding Russian and Soviet bibliographer, ideologist of the introduction of the universal decimal classification in the USSR – B. S. Bodnarsky. The article presents for the first time his little-known historical sources. There are twenty epistles to the Soviet historian S. I.-Ya. Borovoy. Generally, the correspondence of these bibliographers is of undeniable interest in the history of Soviet bibliography in particular, and in the history of historical science. The represented epistles are stored in the State Archives of Odessa region, in the fund of personal origin of professor S. I.-Ya. Borovoy. The published ego-documents cover the period from 1952 to 1968 and are a valuable source on the history of socio-cultural life of the early second half of the twentieth century. The provided materials reflect separate fragments of professional activity of two scientists and their personal and scientific communicative communications with some representatives of the Soviet scientific community. The epistles allow us to reproduce some details of the history of Soviet historical science, certain episodes of the biographies of a number of Soviet scholars of those years against the background of socio-cultural events. The particular interest is the epistles of B. S. Bodnarsky in the context of the study of his interpersonal relationships with colleagues and contain facts for a detailed description of the academic community of the time. The epistles also contain a description of human relations, emotional feelings about certain moments that took place in the scientific environment, a description of the atmosphere of everyday life. The special value of the presented primary sources is that their content demonstrates the presence of attentive and friendly attitude between scientists. To a large extent, the personal connections of S. I.-Ya. Borovoy and an influential scholar in academic circles helped his younger colleague to overcome some difficulties and gain recognition as a scholar in the field of bibliography at the All-Union level. The publication of the letters is accompanied by quite complete comments on their content and introduces a valuable historical source into scientific circulation.

Implementation of Various Classification Systems in Library

Organizing library materials cannot be separated from the application of the classification system which is used as a class-based knowledge determination with the aim of facilitating librarians and librarians in retrieval of collections in the library. This study uses the library research method by comparing the classification systems in 5 libraries from 5 different journals. The results of the study indicate that there are different implementation of classification systems depending on the type of library. The classification system used is Dewey Decimal Classification (DDC), Universal Decimal Classification (UDC), Mandala Classification, Classification System Libraries, Department of Orthotics, Prosthetics, Health Polytechnic, Ministry of Health, Jakarta and Archaeological Library Classification System. The conclusion can be used any classification system as long as it still has the same goal, which is to make it easier for librarians and users to find the desired source of information.

Publishing classification systems on the Internet: representation and use

Classification systems are published primarily in the book form, for various purposes and in different versions. They are identified by the number or year of publication. The authors propose another variant of maintaining classification systems, i.e. in the card format.The authors discuss the issues of presenting classification schedules of popular classification systems on the Internet with special focus on their applications. They explain why privately owned classification systems, like Dewey Decimal Classification (DDC) and Universal Decimal Classification (UDC), are not published on the Internet, while the systems supported by government organizations (e.g. national libraries) are traditionally published openly. The authors provide the example of the Library of Congress Classification (LCC), which is the United States’ National Classification System and which is published on open access. The project of the open presentation of the Library-Bibliographical Classification (LBC) in several versions supplemented with indices on the website of the Russian State Library (RSL) is described in more detail. The possibilities for their use are analyzed.

This paper highlights some of the basic theoretical and practical questions that relate to the classification of historically themed literature for children. In the introductory sections, some basic principles underlying the classification of relevant literature are outlined. After that, some of the main features of the Universal Decimal Classification (UDC), relevant for the classification of historically themed literature for children are discussed. This completes the introductory part of the paper and addresses the main issues related to the classification of historical literature, with emphasis on the processing of books in the field of history for children. By pointing to characteristic examples, an attempt has been made to show the complexity of subject and professional classification in this particular field. This way of classification of these books is making history, both the national and general, more accessible and closer to children. All the examples in this paper are from the practice of the National library of Serbia and are taken from the COBISS.SR database.

Rehabilitation problems in Top Rated Databases

Data from the Web of Science and Scopus databases for November 2019, depth from 1991 to 2018 were used. It was revealed that the high level of the publication rating of Russia, which was noted in 1991-1992, has not yet been achieved in the Scopus database for medical rehabilitation. Measures have been identified to enhance it by increasing the growth rate of the Russian publication flow. It also noted the necessity to reduce Russia's dependence on the monopoly of foreign publishing corporations by creating domestic Russian resources and borrowing the experience of foreign colleagues. The necessary measures should be taken at the level of authors, scientific organizations, the scientific community and the State in order to increase the Russian scientific publication flow in the direction of «Rehabilitation» in foreign top-rated databases. Authors of interdisciplinary articles need to correctly present metadata indicating the relation of the work to the problem of rehabilitation. The necessity is substantiated not only to increase the share of Russian scientific journals in international databases, but also to create domestic high-rating databases, as well as to harmonize the existing regulatory legal acts in regards of terms and definitions in the field of rehabilitation, to bring the headings of the Universal Decimal Classification aligned with the headings of high-ranking international databases. Given the high social significance of the «Rehabilitation» area, it is necessary to include it in the priority list and funded areas at a level corresponding to global trends.

Automatic classification of older electronic texts into the Universal Decimal Classification–UDC

PurposeThe purpose of this study is to develop a model for automated classification of old digitised texts to the Universal Decimal Classification (UDC), using machine-learning methods.Design/methodology/approachThe general research approach is inherent to design science research, in which the problem of UDC assignment of the old, digitised texts is addressed by developing a machine-learning classification model. A corpus of 70,000 scholarly texts, fully bibliographically processed by librarians, was used to train and test the model, which was used for classification of old texts on a corpus of 200,000 items. Human experts evaluated the performance of the model.FindingsResults suggest that machine-learning models can correctly assign the UDC at some level for almost any scholarly text. Furthermore, the model can be recommended for the UDC assignment of older texts. Ten librarians corroborated this on 150 randomly selected texts.Research limitations/implicationsThe main limitations of this study were unavailability of labelled older texts and the limited availability of librarians.Practical implicationsThe classification model can provide a recommendation to the librarians during their classification work; furthermore, it can be implemented as an add-on to full-text search in the library databases.Social implicationsThe proposed methodology supports librarians by recommending UDC classifiers, thus saving time in their daily work. By automatically classifying older texts, digital libraries can provide a better user experience by enabling structured searches. These contribute to making knowledge more widely available and useable.Originality/valueThese findings contribute to the field of automated classification of bibliographical information with the usage of full texts, especially in cases in which the texts are old, unstructured and in which archaic language and vocabulary are used.

Problems of Subject Retrieval in the Electronic Catalogue of Scientific Library: Review of Studies

Scientific libraries use different approaches and tools for subject retrieval. Issues related to electronic subject retrieval are widely discussed in the library community. The purpose of this review is to analyse publications of recent years on the aspects and problems related to subject retrieval in electronic catalogue (EC). For its preparation, the author used publications (and references to them) taken from the national bibliographic database — the Russian Science Citation Index (RSCI); the time coverage is 2003—2019. Particular attention in the studies is focused on the need to combine different information retrieval languages (IRL), thesauruses, subject headings and keywords to ensure effective and multi-aspect search. Since the domestic libraries have accumulated a lot of experience in indexing and retrieval through hierarchical classifications (UDC and LBC), it is necessary to use this at the full extent in the electronic subject retrieval. The authors of the recent studies on subject retrieval consider being the most effective the functioning of classification systems as part of the complex of linguistic tools of electronic catalogue. In the electronic environment, it becomes possible to use classification indexes as a set of characters that maximally reflect the content of the document, what involves the use of all fragments of the index as independent retrieval elements. However, the lexical composition of the classification information retrieval languages needs to be modified for effective use in the electronic catalogue. The main directions here can be as follows: unification of the structure and vocabulary of classification schedules, optimization of the structure of classification systems (using facetization principles), as well as formalization of the use of grammar tools, (it is necessary to ensure the unambiguity of their interpretation in the electronic catalogue). The review presents and analyses the areas where the subject retrieval has been developed in the electronic environment for over the past 16 years. For example, there has been developed and is being implemented the superstructure over Universal Decimal Classification (Library for Natural Sciences of the Russian Academy of Sciences), which allows users of the library to remotely conduct full-fledged subject retrieval. The paper also presents the new developments by the Russian State Library on subject retrieval, in particular, the project “Presentation of classification metadata of electronic libraries using linked data technology”. The author concludes that it is necessary to form a common space of related open data of various libraries.

Mapas Nabais Conde: catalogação do Fundo

Em 2011, a Biblioteca Geral da Universidade de Coimbra adquiriu a Coleção de Mapas Nabais Conde. Após a digitalização dos 1191 mapas, iniciou-se o seu tratamento técnico, que decorreu entre janeiro de 2017 e janeiro de 2018. Terminado o tratamento técnico e analisando a coleção, pode-se observar que, no que concerne à época de publicação, o século XVIII é o mais representado, da mesma forma que o Reino Unido, a França e a Holanda são os países de onde procede a maioria dos editores/impressores. O mapa mais valioso é um mapa de Portugal segundo Álvaro Seco, datado de 1560, e orientado a Ocidente. Grande parte dos mapas são representações de Portugal. Além dos mapas encontramos ainda cartas náuticas, assim como inúmeras imagens que representam vistas de cidades. Quanto ao tratamento catalográfico, foi usada a ISBD (edição consolidada); o Fundo foi classificado com a Classificação Decimal Universal e indexado com termos de indexação da base de dados Millennium da Universidade de Coimbra.
