- Abstract
- On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

- Abstract
- Standard library classification systems like Dewey Decimal Classification (DDC), U.S. Library of Congress Classification (LCC), and Universal Decimal Classification (UDC) are internationally known and widely used by libraries as the tools for organizing information. Charles Ammi Cutter's Expansive Classification (EC), James Duff Brown's Subject Classification (SC), Henry E. Bliss' Bibliographic Classification (BC), and S. R. Ranganathan's Colon Classification (CC) also are standard classification systems, but they are less commonly used compared to aforementioned three systems. All these systems are easy to use and convenient for most general collection libraries. However, these systems are not adequate for some special collections. Libraries with rich collections on Islam also face problems while using these systems, although such libraries often use expansions in the original systems for their collections. This paper examines this problem and presents a potential optimal solution. The author collected data, using a semistructured interview technique, from a representative sample of thirty libraries in eight countries with strong collections in Islam. These data were analyzed employing qualitative methods.

- Abstract
- Notations are systems of symbols that can be combined according to syntactical rules to represent meanings in a specialized domain. In knowledge organization, they are systems of numerals, letters and punctuation marks associated to a concept that mechanically produce helpful sequences of them for arranging books on shelves, browsing subjects in directories and displaying items in catalogues. Most bibliographic classification systems, like Dewey Decimal Classification, use a positional notation allowing for expression of increasingly specific subjects by additional digits. However, some notations like that of Bliss Bibliographic Classification are purely ordinal and do not reflect the hierarchical degree of a subject. Notations can also be expressive of the syntactical structure of compound subjects (common auxiliaries, facets etc.) in various ways. In the digital media, notation can be recorded and managed in databases and exploited to provide appropriate search and display functionalities.

- Abstract
- The paper discusses the challenges of faceted vocabulary organization in universal classifications which treat the universe of knowledge as a coherent whole and in which the concepts and subjects in different disciplines are shared, related and combined. The authors illustrate the challenges of the facet analytical approach using, as an example, the revision of class 72 in UDC. The paper reports on the research undertaken in 2013 as preparation for the revision. This consisted of analysis of concept organization in the UDC schedules in comparison with the Art & Architecture Thesaurus and class W of the Bliss Bibliographic Classification. The paper illustrates how such research can contribute to a better understanding of the field and may lead to improvements in the facet structure of this segment of the UDC vocabulary.

- Abstract
- Facet analysis is proposed as a general theory of knowledge organization, with an associated methodology that may be applied to the development of terminology tools in a variety of contexts and formats. Faceted classifications originated as a means of representing complexity in semantic content that facilitates logical organization and effective retrieval in a physical environment. This is achieved through meticulous analysis of concepts, their structural and functional status (based on fundamental categories), and their inter-relationships. These features provide an excellent basis for the general conceptual modelling of domains, and for the generation of KOS other than systematic classifications. This is demonstrated by the adoption of a faceted approach to many web search and visualization tools, and by the emergence of a facet based methodology for the construction of thesauri. Current work on the Bliss Bibliographic Classification (Second Edition) is investigating the ways in which the full complexity of faceted structures may be represented through encoded data, capable of generating intellectually and mechanically compatible forms of indexing tools from a single source. It is suggested that a number of research questions relating to the Semantic Web could be tackled through the medium of facet analysis.

- Abstract
- Achieving widespread agreement on subject organization is a complex task, and a challenge greater than that of creating a standard bibliographic description for international exchange-the goal of Universal Bibliographic Control (UBC). This article traces the history of the Universal Decimal Classification (UDC), its relationship with other schemes, and opportunities for further collaboration.

- Abstract
- Recent revision of UDC classes has aimed at implementing a more faceted approach. Many compound classes have been removed from the main tables, and more radical revisions of classes (particularly those for Medicine and Religion) have introduced a rigorous analysis, a clearer sense of citation order, and building of compound classes according to a more logical system syntax. The faceted approach provides a means of formalizing the relationships in the classification and making them explicit for machine recognition. In the Bliss Bibliographic Classification (BC2) (which has been a source for both UDC classes mentioned above), terminologies are encoded for automatic generation of hierarchical and associative relationships. Nevertheless, difficulties are encountered in vocabulary control, and a similar phenomenon is observed in UDC. Current work has revealed differences in the vocabulary of humanities and science, notably the way in which terms in the humanities should be handled when these are semantically complex. Achieving a balance between rigour in the structure of the classification and the complexity of natural language expression remains partially unresolved at present, but provides a fertile field for further research.

- Abstract
- Bibliographic classification is among the core activities of Library & Information Science that brings order and proper management to the holdings of a library. Compared to printed media, digital collections present numerous challenges regarding their preservation, curation, organization and resource discovery & access. Therefore, true native perspective is needed to be adopted for bibliographic classification in digital environments. In this research article, we have investigated and reported different approaches to bibliographic classification of digital collections. The article also contributes two evaluation frameworks that evaluate the existing classification schemes and systems. The article presents a bird's-eye view for researchers in reaching a generalized and holistic approach towards bibliographic classification research, where new research avenues have been identified.

- Abstract
- Pragmatism is a metatheoretical perspective within knowledge organization (KO) that derives from an American philosophical tradition active since the late 19th century. Its core feature is commitment to the evaluation of the adequacy of concepts and beliefs through the empirical test of practice: this entails epistemological antifoundationalism, fallibilism, contingency, social embeddedness, and pluralism. This article reviews three variants of Pragmatism that have been historically influential in philosophy-Charles Sanders Pierce's scientifically oriented pragmaticism, William James's subjectivist practicalism, and John Dewey's socially oriented instrumentalism-and indicates points of contact between them and KO theories propounded by Henry E. Bliss, Jesse H. Shera, and Birger Hjørland, respectively. KO applications of classical Pragmatism have tended to converge toward a socially pluralist model characteristic of Dewey. Recently, Richard Rorty's post-modern brand of Neopragmatism has found adherents within KO: whether it provides a more advantageous metatheoretical framework than classical Pragmatism remains to be seen.

- Abstract
- The abstracting and reviewing service zbMATH (zbMATH, 1931- ) is the most comprehensive bibliographic database of mathematical literature. The database uses reviews, keywords and classification for content analysis of mathematical publications. Controlled vocabularies and classification schemes are important for a uniform and standardised analysis of the content and precise information retrieval. Over the last few years, the zbMATH team has started developing machine-based concepts and tools to create controlled vocabularies and to improve the Mathematics Subject Classification (MSC) scheme. Concepts of natural language processing and other machine learning methods, especially neural networks, were adapted to the specific requirements of mathematical information, e.g., named mathematical entities and mathematical formulas. The tools are used for key phrase extraction and classification of mathematical publications. Basing on the extracted key phrases, a prototype for a controlled vocabulary for mathematics was created. The tools and the state of the art are described briefly. These activities will help - in cooperation with authority control for authors, series and institutions - to automate the zbMATH workflow and improve the usefulness and information retrieval capabilities of the database.

- Abstract
- Astronomy classification is often overlooked in classification discourse. Its rarity and obscurity, especially within UK librarianship, suggests it is an underdeveloped strand of classification research and is possibly undervalued in modern librarianship. The purpose of this research is to investigate the suitability and practicalities of the discipline of astronomy adopting a subject-specific faceted classification scheme and to provide a provi-sional outline of a special faceted astronomy classification scheme. The research demonstrates that the application of universal schemes for astronomy classification had left the interdisciplinary subject ill catered for and outdated, making accurate classification difficult for specialist astronomy collections. A faceted approach to classification development is supported by two qualitative literature-based research methods: historical research into astronomy classification and an analytico-synthetic classification case study. The subsequent classification development is influenced through a pragmatic and scholarly-scientific approach and constructed by means of instruction from faceted classification guides by Vickery (1960) and Batley (2005), and faceted classification principles from Ranaganathan (1937). This research fills a gap within classification discourse on specialist interdisciplinary subjects, specifically within astronomy and demonstrates the best means for their classification. It provides a means of assessing further the value of faceted classification within astronomy librarianship.

- Abstract
- The facet-analytic paradigm is probably the most distinct approach to knowledge organization within Library and Information Science, and in many ways it has dominated what has be termed "modern classification theory". It was mainly developed by S.R. Ranganathan and the British Classification Research Group, but it is mostly based on principles of logical division developed more than two millennia ago. Colon Classification (CC) and Bliss 2 (BC2) are among the most important systems developed on this theoretical basis, but it has also influenced the development of other systems, such as the Dewey Decimal Classification (DDC) and is also applied in many websites. It still has a strong position in the field and it is the most explicit and "pure" theoretical approach to knowledge organization (KO) (but it is not by implication necessarily also the most important one). The strength of this approach is its logical principles and the way it provides structures in knowledge organization systems (KOS). The main weaknesses are (1) its lack of empirical basis and (2) its speculative ordering of knowledge without basis in the development or influence of theories and socio-historical studies. It seems to be based on the problematic assumption that relations between concepts are a priori and not established by the development of models, theories and laws.

- Abstract
- Within the last two decades, the development and application of sophisticated information technology has brought about rapid changes in libraries above all in the subject analysis area. The internet technology has facilitated global access to heterogeneous information resources : databases, journals, e-books, digital online resources which now besides the texts include photographs, slides and video clips, as well. There has also been a development of sophisticated online public access catalogues, information gateways, portals, systems based on semantic technologies e.g. question-answering systems, and most recently social networking and a wide scale use of Web 2.0 technologies in libraries.

- Abstract
- From the very beginnings of library automation, subject authority control has been considered an important bibliographic tool in the Czech National Library (CNL). Effective subject access cannot exist without standardised access points. Subject authorities are considered an indispensable reference tool in supporting the selection of subject access points and normalizing content indexing. Most importantly, they are heavily relied upon when it comes to customisation of links between bibliographic records and subject access points in order to create a user-friendly subject browsing and searching environment. Because of the fact that the Universal Decimal Classification (UDC) is widely used in Czech Libraries it has become a readily available language independent subject framework which can be complemented by a more user-friendly subject heading system. In this context, the subject authority control offers a means of enhancing subject headings' access points with terminology and the semantic links available in UDC. Furthermore classification is used to enrich relationships between authority records themselves. The author will discuss in more detail the different aspects and advantages of subject authorities in which a classification and a subject heading system complement one another and the way this is implemented in the CNL.

- Abstract
- S R Ranganathan and Melvil Dewey devised two types of classification schemes viz., faceted and enumerative. Ranganathan's faceted classification scheme is based on postulates, principles and canons. It has a strong theory. While working with the two schemes, similarities are observed. This paper tries to identify and present some relationships.
