The coverage of information science and knowledge organization in the Library of Congress Subject Headings

PurposeThis article examines the Library of Congress Subject Headings (LCSH), which is the most used subject heading system in the world and an instance of a controlled vocabulary (CV).Design/methodology/approachThe method used to examine the system is based on both authors’ subject knowledge in the field of information science (IS) and the subfield of knowledge organization (KO). Core concepts in this domain were examined (1) by checking if they are present or not in the system; (2) if not, by determining whether LCSH contains alternative terms useful for searching documents about the missing concept, by examining books indexed by the Library of Congress; (3) by identifying the semantic relations between subject headings.FindingsThe results demonstrate fundamental problems in the logical consistency of the representation of IS and KO in LCSH.Practical implicationsThe implications for CVs in general are discussed.Originality/valueNo previous study has used our method to examine LCSH’s coverage of IS.

Open-japanese-mesh: assigning MeSH UIDs to Japanese medical terms via open Japanese-English glossaries.

The Medical Subject Headings (MeSH) thesaurus is a controlled vocabulary for indexing biomedical documents that is used for document retrieval and other natural language processing purposes. However, although the original English MeSH is freely available, its Japanese translation has a restricted license. We attempted to create an open alternative, and for this purpose we made a script for assigning MeSH UIDs to Japanese medical terms using Japanese-English glossaries. From the MeSpEn glossary and MEDUTX dictionary, we generated a 12,457-word Japanese-MeSH dictionary.

Centring LGBT2QIA+ Subjects in Knowledge Organization Systems

This paper contains a report of two interdependent knowledge organization (KO) projects for an LGBT2QIA+ library. The authors, in the context of volunteer library work for an independent library, redesigned the classification system and subject cataloguing guidelines to centre LGBT2QIA+ subjects. We discuss the priorities of creating and maintaining knowledge organization systems for a historically marginalized community and address the challenge that queer subjectivity poses to the goals of KO. The classification system features a focus on identity and physically reorganizes the library space in a way that accounts for the multiple and overlapping labels that constitute the currently articulated boundaries of this community. The subject heading system focuses on making visible topics and elements of identity made invisible by universal systems and by the newly implemented classification system. We discuss how this project may inform KO for other marginalized subjects, particularly through process and documentation that prioritizes transparency and the acceptance of an unfinished endpoint for queer KO.

Does the Use of Mobile Phone Affect Male Fertility? A Mini-Review.

Presently, there is a rise in the use of mobile phones, laptops, and wireless internet technologies such as Wi-Fi and 5G routers/modems across the globe; these devices emit a considerable amount of electromagnetic radiation (EMR) which could interact with the male reproductive system either by thermal or nonthermal mechanisms. The aim of this review was to examine the effects of mobile phone use on male fertility. Related studies that reported on the effects of EMR from mobile phones on male fertility from 2003 to 2020 were evaluated. PubMed database was used. The Medical Subject Heading system was used to extract relevant research studies from PubMed. Based on the outcomes of both human and animal studies analyzed in this review, animal and human spermatozoa exposed to EMR emitted by mobile phones had reduced motility, structural anomalies, and increased oxidative stress due to overproduction of reactive oxygen species. Scrotal hyperthermia and increased oxidative stress might be the key mechanisms through which EMR affects male fertility. However, these negative effects appear to be associated with the duration of mobile phone use.

Genetic basis of intracranial aneurysm formation and rupture: clinical implications in the postgenomic era.

Despite the prevalence and impact of intracranial aneurysms (IAs), the molecular basis of their pathogenesis remains largely unknown. Moreover, there is a dearth of clinically validated biomarkers to efficiently screen patients with IAs and prognosticate risk for rupture. The aim of this study was to survey the literature to systematically identify the spectrum of genetic aberrations that have been identified in IA formation and risk of rupture. A literature search was performed using the Medical Subject Headings (MeSH) system of databases including PubMed, EMBASE, and Google Scholar. Relevant studies that reported on genetic analyses of IAs, rupture risk, and long-term outcomes were included in the qualitative analysis. A total of 114 studies were reviewed and 65 were included in the qualitative synthesis. There are several well-established mendelian syndromes that confer risk to IAs, with variable frequency. Linkage analyses, genome-wide association studies, candidate gene studies, and exome sequencing identify several recurrent polymorphic variants at candidate loci, and genes associated with the risk of aneurysm formation and rupture, including ANRIL (CDKN2B-AS1, 9p21), ARGHEF17 (11q13), ELN (7q11), SERPINA3 (14q32), and SOX17 (8q11). In addition, polymorphisms in eNOS/NOS3 (7q36) may serve as predictive markers for outcomes following intracranial aneurysm rupture. Genetic aberrations identified to date converge on posited molecular mechanisms involved in vascular remodeling, with strong implications for an associated immune-mediated inflammatory response. Comprehensive studies of IA formation and rupture have identified candidate risk variants and loci; however, further genome-wide analyses are needed to identify high-confidence genetic aberrations. The literature supports a role for several risk loci in aneurysm formation and rupture with putative candidate genes. A thorough understanding of the genetic basis governing risk of IA development and the resultant aneurysmal subarachnoid hemorrhage may aid in screening, clinical management, and risk stratification of these patients, and it may also enable identification of putative mechanisms for future drug development.

Expressiveness and machine processability of Knowledge Organization Systems (KOS): an analysis of concepts and relations

This study considers the expressiveness (that is the expressive power or expressivity) of different types of Knowledge Organization Systems (KOS) and discusses its potential to be machine-processable in the context of the Semantic Web. For this purpose, the theoretical foundations of KOS are reviewed based on conceptualizations introduced by the Functional Requirements for Subject Authority Data (FRSAD) and the Simple Knowledge Organization System (SKOS); natural language processing techniques are also implemented. Applying a comparative analysis, the dataset comprises a thesaurus (Eurovoc), a subject headings system (LCSH) and a classification scheme (DDC). These are compared with an ontology (CIDOC-CRM) by focusing on how they define and handle concepts and relations. It was observed that LCSH and DDC focus on the formalism of character strings (nomens) rather than on the modelling of semantics; their definition of what constitutes a concept is quite fuzzy, and they comprise a large number of complex concepts. By contrast, thesauri have a coherent definition of what constitutes a concept, and apply a systematic approach to the modelling of relations. Ontologies explicitly define diverse types of relations, and are by their nature machine-processable. The paper concludes that the potential of both the expressiveness and machine processability of each KOS is extensively regulated by its structural rules. It is harder to represent subject headings and classification schemes as semantic networks with nodes and arcs, while thesauri are more suitable for such a representation. In addition, a paradigm shift is revealed which focuses on the modelling of relations between concepts, rather than the concepts themselves.

Represent Changes of Knowledge Organization Systems on the Semantic Web

Traditional knowledge organization systems (KOS) including thesauri, classification schemes, taxonomies, subject heading systems, name authorities, and other lists of terms and codes have been playing important roles in indexing, information organization, and retrieval. With the advent of the semantic web, a large number of them have been converted into Linked Open Data (LOD) datasets. Since the Simple Knowledge Organization Systems (SKOS) and SKOS eXtension for Labels (SKOS-XL) are languages for representation of knowledge organization systems, they have been applied to knowledge organization systems. In this article, the issues surrounding changes, versioning control, and evolution of KOS are investigated. From KOS services providers and consumers perspectives, this study focuses on representation of changes on the semantic web.

Representation of indigenous cultures: considering the Hawaiian hula

PurposeThe purpose of this paper is to explore the representation of Kanaka Maoli (Hawaiian) Hula Dance in traditional systems of representation and organization.Design/methodology/approachThis exploratory study analyzes the controlled and natural language vocabularies employed for the representation and organization of Hawaiian culture, in particular Hawaiian hula. The most widely accepted and used systems were examined: classification systems (Library of Congress Classification and Dewey Decimal Classification), subject heading systems (Library of Congress Subject Headings and authority files (Library of Congress and OCLC Authority Files), and citation indexing systems (Web of Science Social Sciences and Art and Humanities databases).FindingsAnalysis of various tools of representation and organization revealed biases and diasporization in depictions of Hawaiian culture. The study emphasizes the need to acknowledge the aesthetic perspective of indigenous people in their organization and presentation of their own cultural knowledge and advocates a decolonizing methodology to promote alternative information structures in indigenous communities.Originality/valueThis study contributes to the relatively limited scholarship on representation and organization for indigenous knowledge organization systems, in particular Hawaiian culture. Research suggests that access to Native Hawaiian cultural heritage will raise awareness among information professionals in Hawai’i to the beauty of Native Hawaiian epistemology.

ISO 25964-2: interoperabilidad de los tesauros con otros sistemas de organización del conocimiento en contextos semánticos

The second part of ISO 25964 on interoperability of thesauri with other knowledge organization systems is presented in the context of the Internet and semantic web. A review is offered of the main mapping models, the main semantic relation mappings, and the intricacies of mapping thesauri against bibliographical and archival classifications, taxonomies, subject heading systems, ontologies, terminologies, authority lists, and synonym rings. Finally, the implications of the ISO 25964 standard for the theory and practice of knowledge organization systems are discussed.

SKOS concepts and natural language concepts: An analysis of latent relationships in KOSs

The vehicle to represent Knowledge Organisation Systems (KOSs) in the environment of the Semantic Web and linked data is the Simple Knowledge Organisation System (SKOS). SKOS provides a way to assign a Uniform Resource Identifier (URI) to each concept, and this URI functions as a surrogate for the concept. This fact makes of main concern the need to clarify the URIs’ ontological meaning. The aim of this study is to investigate the relationship between the ontological substance of KOS concepts and concepts revealed through the grammatical and syntactic formalisms of natural language. For this purpose, we examined the dividableness of concepts in specific KOSs (i.e. a thesaurus, a subject headings system and a classification scheme) by applying Natural Language Processing (NLP) techniques (i.e. morphosyntactic analysis) to the lexical representations (i.e. RDF literals) of SKOS concepts. The results of the comparative analysis reveal that, despite the use of multi-word units, thesauri tend to represent concepts in a way that can hardly be further divided conceptually, while subject headings and classification schemes – to a certain extent – comprise terms that can be decomposed into more conceptual constituents. Consequently, SKOS concepts deriving from thesauri are more likely to represent atomic conceptual units and thus be more appropriate tools for inference and reasoning. Since identifiers represent the meaning of a concept, complex concepts are neither the most appropriate nor the most efficient way of modelling a KOS for the Semantic Web.

A study on the structure of the Chinese information policy domain framework

Information policies, the guidelines and standards for the macro information management of a nation, play an important role in the course of informationization in China. Owing to the absence of an authoritative framework of Chinese information policies, this research generated a comprehensive, three-level classification of information policy domains, based on policy data collected from Chinalawinfo.com , owned by the Legal Information Centre of Peking University. We constructed the first level with general domains derived from the theory of information’s life cycle. The second- and third-level domains were then determined according to the results of our clustering analysis, and their keywords were enriched and standardized using the Chinese Classification and Subject Headings System. The significance of this research is not only that it has identified blind spots existing in information policy making and research, but also that the new Chinese information policy domain framework will help regulate informationization in China.

MapRank: Geographical Search for Cartographic Materials in Libraries

Searches for cartographic materials have previously been carried out using conventional library search systems. However, this kind of search method often proves to be inadequate, as the lack of suitable user interfaces means that queries have to be formulated in words. Furthermore, indexing based on geographical names does not adequately describe the spatial dimension of cartographic material, and geographical names also tend to be ambiguous and inclined to change. A web-based geographical search system (geosearch), which analyzes the geographical coordinates of MARC21 field 034, has been developed for the Swiss research portal for maps. The geosearch enables cartographic material to be found quickly and efficiently on the basis of its location and spatial extent via an intuitively accessible user interface. This is achieved with a cleverly devised ranking algorithm (MapRank®) and an innovative indexing mechanism. The number of search results can also be restricted by applying filters relating to the publication period and map scale. The geosearch is proving to be a powerful search tool which, in an open-ended search scenario, can be used to find roughly double the amount of relevant cartographic material within a short space of time. The system is intuitive to operate and no previous knowledge is required. It also offers further strengths, such as the ability to search through extremely large quantities of data quickly and independently from the various subject heading systems and thesauri. This makes the geosearch an ideal tool for carrying out map searches in metacatalogs.

Linking folksonomy to Library of Congress subject headings: an exploratory study

PurposeThe purpose of this paper is to investigate the linking of a folksonomy (user vocabulary) and LCSH (controlled vocabulary) on the basis of word matching, for the potential use of LCSH in bringing order to folksonomies.Design/methodology/approachA selected sample of a folksonomy from a popular collaborative tagging system, Delicious, was word‐matched with LCSH. LCSH was transformed into a tree structure called an LCSH tree for the matching. A close examination was conducted on the characteristics of folksonomies, the overlap of folksonomies with LCSH, and the distribution of folksonomies over the LCSH tree.FindingsThe experimental results showed that the total proportion of tags being matched with LC subject headings constituted approximately two‐thirds of all tags involved, with an additional 10 percent of the remaining tags having potential matches. A number of barriers for the linking as well as two areas in need of improving the matching are identified and described. Three important tag distribution patterns over the LCSH tree were identified and supported: skewedness, multifacet, and Zipfian‐pattern.Research limitations/implicationsThe results of the study can be adopted for the development of innovative methods of mapping between folksonomy and LCSH, which directly contributes to effective access and retrieval of tagged web resources and to the integration of multiple information repositories based on the two vocabularies.Practical implicationsThe linking of controlled vocabularies can be applicable to enhance information retrieval capability within collaborative tagging systems as well as across various tagging system information depositories and bibliographic databases.Originality/valueThis is among frontier works that examines the potential of linking a folksonomy, extracted from a collaborative tagging system, to an authority‐maintained subject heading system. It provides exploratory data to support further advanced mapping methods for linking the two vocabularies.

Palliative treatment of intractable hematuria in context of advanced bladder cancer: a systematic review.

In a patient with bladder urothelial cancer that is not suitable for or does not choose curative treatment, intractable hematuria is a disastrous condition. In this article, we tried to review the literature and extract a stepwise approach for palliative treatment of hematuria in these patients. The MEDLINE was searched with the help of the Medical Subject Headings system using different combinations of terms urinary bladder neoplasm, hematuria, carboprost, cyclophosphamide, cystitis, alum, and hyperbaric oxygenation. The articles were separately reviewed by the two authors and verified by each other. Eventually, a decision tree was developed for management of gross hematuria in patients with bladder cancer. Although, there was not any reported randomized controlled trial or prospectively designed study, the available case series were rather expressive to draw out a logical approach. Formalin has a grave adverse effect profile and recommended only in special circumstances. For management of each case of gross hematuria in bladder cancer, the etiology of bleeding is the most important determinant. Hematuria in the context of advanced bladder neoplasms can now be effectively treated with fewer side effects using all available modalities in a logical holistic approach. We proposed a decision tree for management of hematuria in this context. However, regarding lack of well-designed trials, a treatment method should be based on individualized scenarios and clinical experience, bringing into account the patient's preferences.

Keyword vs controlled vocabulary searching: the one with the most tools wins

Sevim McCutcheon explores the strengths and weaknesses of keyword and controlled vocabulary searching with particular reference to the Library of Congress Subject Headings system, coming to the conclusion (as exemplified by the practice in her own university, Kent State, Ohio, USA) that each system has its strengths and weaknesses, that in practice they are complementary to one another, and that the best results are achieved by using the two in combination: in other words, they who have the most tools win.
