Abstract

In 2017, the University of Virginia (U.Va.) will launch a two year initiative to celebrate the bicentennial anniversary of the University's founding in 1819. The U.Va. Library is participating in this event by digitizing some 20,000 photographs and negatives that document student life on the U.Va. grounds in the 1960s and 1970s. Metadata librarians and archivists are well-versed in the challenges associated with generating digital content and accompanying description within the context of limited resources. This paper describes how technology and new approaches to metadata design have enabled the University of Virginia's Metadata Analysis and Design Department to rapidly and successfully generate accurate description for these digital objects. Python's pandas module improves efficiency by cleaning and repurposing data recorded at digitization, while the lxml module builds MODS XML programmatically from CSV tables. A simplified technique for subject heading selection and assignment in Google Sheets provides a collaborative environment for streamlined metadata creation and data quality control.

Abstract

The fundamental principle of order in the library catalogue is the authorship principle, which serves as the organizing node of an alphabetico-classed system, in which "texts" of "works" are organized first alphabetically by uniform title of the progenitor work and then are subarranged using titles for variant instantiations, under the heading for an "author." We analyze case studies of entries from (1) the first documented imperial library catalogue, the Seven Epitomes (Qilue [??]), in China; (2) Abelard's Works, which featured prominently in the 1848 testimony of Antonio Panizzi; and (3) The French Chef and the large family of instantiated works associated with it. Our analysis shows that the catalogue typically contains many large superwork sets. A more pragmatic approach to the design of catalogues is to array descriptions of resources in relation to the superwork sets to which they might belong. In all cases, a multidimensional faceted arrangement incorporating ideational nodes from the universe of recorded knowledge holds promise for greatly enhanced retrieval capability.

Abstract

Purpose - This paper sets out to discuss the use of information extraction (IE), a natural language-processing (NLP) technique to assist "rich" semantic indexing of diverse archaeological text resources. The focus of the research is to direct a semantic-aware "rich" indexing of diverse natural language resources with properties capable of satisfying information retrieval from online publications and datasets associated with the Semantic Technologies for Archaeological Resources (STAR) project. Design/methodology/approach - The paper proposes use of the English Heritage extension (CRM-EH) of the standard core ontology in cultural heritage, CIDOC CRM, and exploitation of domain thesauri resources for driving and enhancing an Ontology-Oriented Information Extraction process. The process of semantic indexing is based on a rule-based Information Extraction technique, which is facilitated by the General Architecture of Text Engineering (GATE) toolkit and expressed by Java Annotation Pattern Engine (JAPE) rules. Findings - Initial results suggest that the combination of information extraction with knowledge resources and standard conceptual models is capable of supporting semantic-aware term indexing. Additional efforts are required for further exploitation of the technique and adoption of formal evaluation methods for assessing the performance of the method in measurable terms. Originality/value - The value of the paper lies in the semantic indexing of 535 unpublished online documents often referred to as "Grey Literature", from the Archaeological Data Service OASIS corpus (Online AccesS to the Index of archaeological investigationS), with respect to the CRM ontological concepts E49.Time Appellation and P19.Physical Object.

Abstract

Analytico-synthetic and faceted classifications, such as Universal Decimal Classification (UDC) express content of documents with complex, pre-combined classification codes. Without classification authority control that would help manage and access structured notations, the use of UDC codes in searching and browsing is limited. Existing UDC parsing solutions are usually created for a particular database system or a specific task and are not widely applicable. The approach described in this paper provides a solution by which the analysis and interpretation of UDC notations would be stored into an intermediate format (in this case, in XML) by automatic means without any data or information loss. Due to its richness, the output file can be converted into different formats, such as standard mark-up and data exchange formats or simple lists of the recommended entry points of a UDC number. The program can also be used to create authority records containing complex UDC numbers which can be comprehensively analysed in order to be retrieved effectively. The Java program, as well as the corresponding schema definition it employs, is under continuous development. The current version of the interpreter software is now available online for testing purposes at the following web site: http://interpreter-eto.rhcloud.com. The future plan is to implement conversion methods for standard formats and to create standard online interfaces in order to make it possible to use the features of software as a service. This would result in the algorithm being able to be employed both in existing and future library systems to analyse UDC numbers without any significant programming effort.

Abstract

The Functional Requirements for Subject Authority Data (FRSAD) conceptual model identifies entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as a subject of a work) and nomen (any sign or sequence of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question, can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system is used as a case study to test applicability of the FRSAD model for classification data, and as a springboard for a general discussion of issues related to the use of FRSAD for the representation of classification data.

Abstract

General concepts are all those form-categorial concepts which - attached to a specific concept of a classification system or thesaurus - can help to widen, sometimes even in a syntactical sense, the understanding of a case. In some existing universal classification systems such concepts have been named "auxiliaries" or "common isolates" as in the Colon Classification (CC). However, by such auxiliaries, different kinds of such concepts are listed, e.g. concepts of space and time, concepts of races and languages and concepts of kinds of documents, next to them also concepts of kinds of general activities, properties, persons, and institutions. Such latter kinds form part of the nine aspects ruling the facets in the Information Coding Classification (ICC) through the principle of using a Systematiser for the subdivision of subject groups and fields. Based on this principle and using and extending existing systems of such concepts, e.g. which A. Diemer had presented to the German Thesaurus Committee as well as those found in the UDC, in CC and attached to the Subject Heading System of the German National Library, a faceted classification is proposed for critical assessment, necessary improvement and possible later use in classification systems and thesauri.

Abstract

We analyzed how effort in searching is associated with search output and task outcome. In a field study, we examined how students' search effort for an assigned learning task was associated with precision and relative recall, and how this was associated to the quality of learning outcome. The study subjects were 41 medical students writing essays for a class in medicine. Searching in Medline was part of their assignment. The data comprised students' search logs in Medline, their assessment of the usefulness of references retrieved, a questionnaire concerning the search process, and evaluation scores of the essays given by the teachers. Pearson correlation was calculated for answering the research questions. Finally, a path model for predicting task outcome was built. We found that effort in the search process degraded precision but improved task outcome. There were two major mechanisms reducing precision while enhancing task outcome. Effort in expanding Medical Subject Heading (MeSH) terms within search sessions and effort in assessing and exploring documents in the result list between the sessions degraded precision, but led to better task outcome. Thus, human effort compensated bad retrieval results on the way to good task outcome. Findings suggest that traditional effectiveness measures in information retrieval should be complemented with evaluation measures for search process and outcome.

Abstract

Purpose - This study aims to explore the journal bibliometric characteristics of the Journal of Documentation (JOD) and the subject relationship with other disciplines by citation analysis. Design/methodology/approach - The citation data were drawn from references of each article of JOD during 1998 and 2008. Ulrich's Periodicals Directory, Library of Congress Subject Heading, retrieved from the WorldCat and LISA database were used to identify the main class, subclass and subject of cited journals and books. Findings - The results of this study revealed that journal articles are the most cited document, followed by books and book chapters, electronic resources, and conference proceedings, respectively. The three main classes of cited journals in JOD papers are library science, science, and social sciences. The three subclasses of non-LIS journals that were highly cited in JOD papers are Science, "Mathematics. Computer science", and "Industries. Land use. Labor". The three highly cited subjects of library and information science journals encompass searching, information work, and online information retrieval. The most cited main class of books in JOD papers is library and information science, followed by social sciences, science, "Philosophy. Psychology. Religion." The three highly cited subclasses of books in JOD papers are "Books (General). Writing. Paleography. Book industries and trade. Libraries. Bibliography," "Philology and linguistics," and Science, and the most cited subject of books is information storage and retrieval systems. Originality/value - Results for the present research found that information science, as represented by JOD, is a developing discipline with an expanding literature relating to multiple subject areas.

Abstract

The paper introduces TinREAD (The Information Navigator for Readers), an integrated library system produced by IME Romania. The main feature of interest is the way TinREAD can handle a classification-based thesaurus in which verbal index terms are mapped to classification notations. It supports subject authority control interlinking the authority files (subject headings and UDC system). Authority files are used for indexing consistency. Although it is said that intellectual indexing is, unlike automated indexing, both subjective and inconsistent, TinREAD is using intellectual indexing as input (the UDC notations assigned to documents) for the automated indexing resulting from the implementation of a thesaurus structure based on UDC. Each UDC notation is represented by a UNIMARC subject heading record as authority data. One classification notation can be used to search simultaneously into more than one corresponding thesaurus. This way natural language terms are used in indexing and, at the same time, the link with the corresponding classification notation is kept. Additionally, the system can also manage multilingual data for the authority files. This, together with other characteristics of TinREAD are largely discussed and illustrated in the paper. Problems encountered and possible solutions to tackle them are shown.

Abstract

The history of controlled vocabularies in libraries has long carried the promise of improved retrieval systems based on common goals and shared efforts. This is especially true of subject vocabularies whose data have been managed at two levels. Firstly, in management systems of their own, from which vocabulary products are derived, as in the case of the most commonly used subject heading languages, thesauri and classification schemes. Secondly, in the so called library authority files, that may apply such vocabularies or be used to develop local ones, to control subject access to a given library or bibliographic collection. This two-levelled model of building and sharing subject vocabularies' data is about to change. For many decades the concept of 'intellectual sharing' has been prevalent in such activities, underpinning re-use by adoption and/or collaboration in the management of shared subject systems. Although the Internet has enabled the exposure of centrally managed subject systems and library authority files it has done little to alleviate the significant efforts needed for a full deployment of network shared vocabularies. In particular, the use of classification systems did not advance much. While in theory their potential for subject interoperability across domains and languages is recognized, classifications remain poorly used in practice. They still lack intelligent means to effectively connect and communicate data throughout the network, in a synchronic and non-redundant way. More recently, the development of web technologies has leveraged the concepts of connection, communication and sharing of data to a new level, through linked data. What changes will this bring to the architecture of library subject authority data? Will classification systems live to see the age of their full and easy deployment?

Abstract

The field of knowledge organization (KO) can be described as composed of the four distinct but connected layers of theory, systems, representation, and application. This paper focuses on the relations between KO theory and KO systems. It is acknowledged how the structure of KO systems is the product of a mixture of ontological, epistemological, and pragmatical factors. However, different systems give different priorities to each factor. A more ontologically-oriented approach, though not offering quick solutions for any particular group of users, will produce systems of wide and long-lasting application as they are based on general, shareable principles. I take the case of the ontological theory of integrative levels, which has been considered as a useful source for general classifications for several decades, and is currently implemented in the Integrative Levels Classification system. The theory produces a sequence of main classes modelling a natural order between phenomena. This order has interesting effects also on other features of the system, like the citation order of concepts within compounds. As it has been shown by facet analytical theory, it is useful that citation order follow a principle of inversion, as compared to the order of the same concepts in the schedules. In the light of integrative levels theory, this principle also acquires an ontological meaning: phenomena of lower level should be cited first, as most often they act as specifications of higher-level ones. This ontological principle should be complemented by consideration of the epistemological treatment of phenomena: in case a lower-level phenomenon is the main theme, it can be promoted to the leading position in the compound subject heading. The integration of these principles is believed to produce optimal results in the ordering of knowledge contents.

Abstract

Vernetzung und Netzwerke finden sich allerorten, haben vielerlei Qualität und Materialität, erfüllen diverse Zwecke und Funktionen und konstituieren unterschiedliche Infrastrukturen, nicht nur kommunikativer und sozialer Art. Mit der Entwicklung und Verbreitung der Informationstechnik, der globalen Transport- und Vermittlungssysteme und endlich der anhaltenden Digitalisierung werden der Begriff und die damit bezeichnete Konnektivität omnipräsent und auf digitale Netze fokussiert, die im Internet als dem Netz der Netze seinen wichtigsten und folgenreichsten Prototypen findet. Dessen Entwicklung wird kompakt dargestellt. Die bereits vorhandenen und verfügbaren Anwendungsfelder sowie die künftigen (Industrie 4.0, Internet der Dinge) lassen revolutionäre Umbrüche in allen Segmenten der Gesellschaft erahnen, die von der nationalstaatlichen Gesetzgebung und Politik kaum mehr gesteuert und kontrolliert werden, neben unbestreitbar vielen Vorzügen und Verbesserungen aber auch Risiken und Benachteiligungen zeitigen können.

Abstract

Purpose The purpose of this paper is to analyse the author self-citation behavior in the field of Library and Information Science. Various factors governing the author self-citation behavior have also been studied. Design/methodology/approach The 2012 edition of Social Science Citation Index was consulted for the selection of LIS journals. Under the subject heading "Information Science and Library Science" there were 84 journals and out of these 12 journals were selected for the study based on systematic sampling. The study was confined to original research and review articles that were published in select journals in the year 2009. The main reason to choose 2009 was to get at least five years (2009-2013) citation data from Web of Science Core Collection (excluding Book Citation Index) and SciELO Citation Index. A citation was treated as self-citation whenever one of the authors of citing and cited paper was common, i.e., the set of co-authors of the citing paper and that of the cited one are not disjoint. To minimize the risk of homonyms, spelling variances and misspelling in authors' names, the authors compared full author names in citing and cited articles. Findings A positive correlation between number of authors and total number of citations exists with no correlation between number of authors and number/share of self-citations, i.e., self-citations are not affected by the number of co-authors in a paper. Articles which are produced in collaboration attract more self-citations than articles produced by only one author. There is no statistically significant variation in citations counts (total and self-citations) in works that are result of different types of collaboration. A strong and statistically significant positive correlation exists between total citation count and frequency of self-citations. No relation could be ascertained between total citation count and proportion of self-citations. Authors tend to cite more of their recent works than the work of other authors. Total citation count and number of self-citations are positively correlated with the impact factor of source publication and correlation coefficient for total citations is much higher than that for self-citations. A negative correlation exhibits between impact factor and the share of self-citations. Of particular note is that the correlation in all the cases is of weak nature. Research limitations/implications The research provides an understanding of the author self-citations in the field of LIS. readers are encouraged to further the study by taking into account large sample, tracing citations also from Book Citation Index (WoS) and comparing results with other allied subjects so as to validate the robustness of the findings of this study. Originality/value Readers are encouraged to further the study by taking into account large sample, tracing citations also from Book Citation Index (WoS) and comparing results with other allied subjects so as to validate the robustness of the findings of this study.

Abstract

Hier und heute bezeichnen die Worte Freiheit und Sicherheit vor allem jene politischen Begriffe, die den rhetorischen Referenzrahmen im sicherheitspolitischen Koordinatensystem unserer westlichen Demokratien nach Innen und Außen abstecken. Legitimatorische und agitatorische Diskurse, Wahlkampfrhetorik und Parlamentsdebatten, Zivilgesellschaft und politische Administration bemühen regelmäßig und formelhaft Begriffe von Freiheit und Sicherheit für ihre jeweiligen Zwecke. Dabei werden die Begriffe oft in ein oppositionelles Verhältnis zueinander gesetzt: Mehr (z.B. innenpolitische) Sicherheit bedeutet dann weniger (z.B. persönliche) Freiheit, und umgekehrt. Oder Sicherheit wird zur Voraussetzung und Bedingung von Freiheit (z.B. in der "wehrhaften Demokratie"). Die operationalen Wurzeln dieser Begrifflichkeit in der Wahrnehmung, im Verhalten und Handeln gelangen dabei jedoch weit aus dem Blick. Welche initialen und konsolidierten Eindrücke, Einsichten und Erfahrungen sind es, auf die wir uns affektiv und rational mit diesen Begriffen beziehen? Wie fühlt sich Sicherheit an? Wie sieht Verhalten oder Handeln als Ausdruck von Freiheit aus? Kann man Freiheit spüren? Zu welcher Freiheit ist man überhaupt fähig? Wieviel Sicherheit ist für das Leben nötig? Welche operationalen Evidenzen bieten Wahrnehmung und Verhalten für die Begriffe der Sicherheit und Freiheit vor all ihren ideologischen Aufladungen, historischen Interpretationen und philosophischen Explikationen?
