    Abstract
    iQvoc is a new open source SKOS-XL vocabulary management tool developed by the Federal Environment Agency, Germany, and innoQ Deutschland GmbH. Its immediate purpose is maintaining and publishing reference vocabularies in the upcoming Linked Data cloud of environmental information, but it may be easily adapted to host any SKOS- XL compliant vocabulary. iQvoc is implemented as a Ruby on Rails application running on top of JRuby - the Java implementation of the Ruby Programming Language. To increase the user experience when editing content, iQvoc uses heavily the JavaScript library jQuery.

    Abstract
    Als eines der Ergebnisse der 2007 zwischen BVB und KOBV geschlossenen strategischen Allianz konnte am 12. September 2011 Mable+, eine Java-gestützte OpenSource-Software zur automatischen Daten- und Fehleranalyse von Bibliothekskatalogen, veröffentlicht werden. Basierend auf dem MAB-Datenaustauschformat ermöglicht Mable+ die formale Prüfung von Katalogdaten verbunden mit einer statistischen Auswertung über die Verteilung der Felder. Dazu benötigt es einen MAB-Abzug des Katalogs im MAB2-Bandformat mit MAB2-Zeichensatz. Dieses Datenpaket wird innerhalb weniger Minuten analysiert. Als Ergebnis erhält man einen Report mit einer allgemeinen Statistik zu den geprüften Datensätzen (Verteilung der Satztypen, Anzahl der MAB-Felder, u.a.), sowie eine Liste gefundener Fehler. Die Software wurde bereits bei der Migration der Katalogdaten aller KOBV-Bibliotheken in den B3Kat erfolgreich eingesetzt. Auf der Projekt-Webseite http://mable.kobv.de/ findet man allgemeine Informationen sowie diverse Anleitungen zur Nutzung des Programms. Die Software kann man sich unter http://mable.kobv.de/download.html herunterladen. Derzeit wird ein weiterführendes Konzept zur Nutzung und Modifizierung der Software entwickelt.

    Abstract
    Die Welt der Information ist zunehmend vernetzt. Quellen aller Art werden in digitaler Form über das Internet verbreitet. Die inhaltliche Erschließung dieser Quellen durch Schlagwörter bietet dem Nutzer, insbesondere dem Wissenschaftler, einen unentbehrlichen thematischen Zugang zu diesen Quellen. Die "Regeln für den Schlagwortkatalog" (RSWK) sind das maßgebende Regelwerk für die verbale Inhaltserschließung im deutschsprachigen Raum. Sie sind zugleich in der bibliotheks- und informationswissenschaftlichen Fachwelt kontrovers diskutiert worden. Dennoch fehlt bislang eine wissenschaftliche monographische Darstellung der RSWK. Die Arbeit will einen Beitrag dazu leisten, indem sie die durch dieses Regelwerk bestimmte Indexierungssprache als Zeichensystem in seiner semantischen, syntaktischen und pragmatischen Dimension analysiert. Die theoretische Grundlage der Arbeit bietet die Semiotik von Charles Morris. Ausgehend davon wird der Typus der Indexierungssprache unter zeichentheoretischen Gesichtspunkten dargestellt. Für die konkrete Analyse der RSWK als Schlagwortsprache werden dann zwei auf der internationalen Ebene der bibliothekarischen Wissensorganisation vorgelegte Unternehmungen als Analyseinstrumente herangezogen, nämlich einmal die "Functional requirements for bibliographic records" (FRBR und zum anderen die "Principles underlying subject heading languages" Gestützt auf die Ergebnisse dieser Untersuchungen wird die RSWK als Schlagwortsprache im Hinblick auf ihre theoretische Angemessenheit und Konsistenz untersucht. Die Analyse kennzeichnet die RSWK als synthetische kettenbildende Schlagwortsprache mit ihren drei charakteristischen Ebenen: dem Schlagwort, der Schlagwortkette und dem Indexat als der Gesamtheit der Schlagwortketten. Es werden semiotische Defizite dieser Schlagwortsprache im Hinblick auf ihre Vollständigkeit und Widerspruchsfreiheit aufgezeigt und entsprechende Vorschläge für ihre Weiterentwicklung gewonnen. Weitere Abschnitte widmen sich dann einzelnen Schlagwortkategorien und den durch sie repräsentierten bibliographischen Entitäten: den Körperschaften, den Ereignissen und den Werken.

    Abstract
    In the last few years projects such as DESIRE, MACS, CrissCross and KoMoHe have demonstrated the benefits as well as the challenges of mapping between controlled vocabularies. Each project has taken a slightly different approach to the definition and implementation of appropriate types of mapping. The mapping types supported by SKOS are slightly different again. In an ideal world, all major databases would be interconnected; all widely used thesauri, classification schemes and subject heading schemes would map to each other; and all of us would use the same basic types of mapping to enable universal interoperability. Or would we? This paper will discuss the feasibility and desirability of agreeing and implementing standardized mapping types.

    Abstract
    This paper reviews Ranganathan's description of subject from mathematical angle. Ranganathan was highly influenced by Nineteenth Century mathematician George Cantor and he used the concept of infinity in developing an axiomatic interpretation of subject. Majority of library scientists interpreted the concept of subject merely as a term or descriptor or heading to include the same in cataloguing and subject indexing. Some library scientists interpreted subject on the basis of document, i.e. from the angle of the concept of aboutness or epistemological potential of the document etc. Some people explained subject from the viewpoint of social, cultural or socio-cultural process. Attempts were made to describe subject from epistemological viewpoint. But S R Ranganathan was the first to develop an axiomatic concept of subject on its own. He built up an independent idea of subject that is ubiquitously pervasive with human cognition process. To develop the basic foundation of subject, he used the mathematical concepts of infinity and infinitesimal and construed the set of subjects or universe of subjects as continuous infinite universe. The subject may also exist in extremely micro-form, which was termed as spot subject and analogized with point, which is dimensionless having only an existence. The influence of Twentieth Century physicist George Gamow on Ranganathan's thought has also been discussed.

    Abstract
    Sears List of Subject Headings (Miller and McCarthy 2010), first published in 1923, is now in its 20th edition. Like most subject headings lists, apart from being a list of preferred (and non-preferred) headings, it also provides patterns, clear instructions, and examples for coining new subject headings not explicitly listed. Key headings form a vital part of the system of coining new headings. It is proposed that more key headings should be designated. Some candidate headings are described. One far-reaching provision seems to be the use of a subdivision of a preferred heading with all of its NTs. Thus, every preferred heading is a potential key heading for all of its NTs. This proposal works on the principle that what is true of a class is true of its narrower classes of all types. Applying this principle will enormously enhance the capacity of the List without adding even an iota to its text and size.

    Abstract
    This article argues that the use of the Library of Congress subject heading "East Indians" in reference to individuals from India represents not only a problematic vestige of colonialism, but also a failure of the principle of literary warrant. It provides an overview of the term's historical roots and then examines whether the term is still widely used in published resources. Although assigning a subject heading is not easy and can involve a choice between contested realities of diverse peoples, the author contends that a rejection of outdated terminology is central to providing any culturally sensitive tool for resource organization.

    Abstract
    Medical insurance fraud is common in many countries' medical insurance systems and represents a serious threat to the insurance funds and the benefits of patients. In this paper, we present an inference model of medical insurance fraud detection, based on a medical detection domain ontology that incorporates the knowledge base provided by the Medical Terminology, NKIMed, and Chinese Library Classification systems. Through analyzing the behaviors of irregular and fraudulent medical services, we defined the scope of the medical domain ontology relevant to the task and built the ontology about medical sciences and medical service behaviors. The ontology then utilizes Semantic Web Rule Language (SWRL) and Java Expert System Shell (JESS) to detect medical irregularities and mine implicit knowledge. The system can be used to improve the management of medical insurance risks.

    Abstract
    Cataloging practices for video games have been in flux since the late 1970s, often lagging behind technological developments. This article describes the history of descriptive cataloging practices and MARC coding for video games. Also discussed are the special problems presented by Library of Congress subject heading and uniform title practice, which were developed for book cataloging rather than for the cataloging of video games themselves.

    Abstract
    The following paper deals with an automatic text classification method which does not require training documents. For this method the German Subject Heading Authority File (SWD), provided by the linked data service of the German National Library is used. Recently the SWD was enriched with notations of the Dewey Decimal Classification (DDC). In consequence it became possible to utilize the subject headings as textual representations for the notations of the DDC. Basically, we we derive the classification of a text from the classification of the words in the text given by the thesaurus. The method was tested by classifying 3826 OAI-Records from 7 different repositories. Mean reciprocal rank and recall were chosen as evaluation measure. Direct comparison to a machine learning method has shown that this method is definitely competitive. Thus we can conclude that the enriched version of the SWD provides high quality information with a broad coverage for classification of German scientific articles.

    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
    "dwibindu vargiikaraNa" is the Kannada rendering of the revised Colon Classification, 7th Edition, intended essentially for the classification of macro documents. This paper discusses the planning, preparation, and features of Colon Classification (CC) in Kannada, one of the major Indian languages as well as the Official Language of Karnataka, and uploading the CC on the web. Linguistic issues related to the Kannada rendering are discussed with possible solutions. It creates facilities in the field of Indexing Language (IL) to prepare products such as, Subject Heading List, Information Retrieval Thesaurus, and creation of subject glossaries or updating the available subject dictionaries in Kannada.

    Abstract
    The US cataloging community is an interorganizational network with the Library of Congress (LC) as the lead organization, which reserves to itself the power to shape cataloging rules. Peripheral members of the network who are interested in modifying changes to the rules or to the network can use various strategies for organizational change that incorporate building ties to the decision-makers located at the hub of the network. The story of William E. Studwell's campaign for a subject heading code illustrates how some traditional scholarly methods of urging change-papers and presentations-are insufficient to achieve reform in an interorganizational network, absent strategies to build alliances with the decision makers.

    Abstract
    This article examines the classification of migration and the political implications of its vocabulary. It begins with an analysis of the challenge that the topic of migration poses to traditional methods of classification. These challenges are evident in the case study of the 2016 petition to change the subject heading of "Illegal aliens" at the Library of Congress, the Library's proposal to replace the term with "noncitizens" and "illegal immigration," and subsequent pressure from the House of Representatives to reinstate the original phrasing in order to match the terminology of federal laws.

    Abstract
    This research concerns the frequency of the assignment of author-supplied keyword strings and cataloger supplied subject heading strings within a library catalog. The results reveal that, on average, more author-assigned keywords and more cataloger-assigned Library of Congress Subject Headings were assigned to works emerging from the arts & humanities than to works emerging from the social sciences and science, technology, engineering, and mathematics (STEM) disciplines. STEM disciplines in particular received a lower amount of topical metadata, in part because of the under-assignment of name/title, geographical, and corporate subject headings. These findings reveal how librarians could increase their understanding of how topical access is functioning within academic disciplines.

    Abstract
    In order to improve the organization of classical music information resources, we constructed a classical music recording ontology, on top of which we then designed an online classical music catalog. Our construction of the classical music recording ontology consisted of three steps: identifying the purpose, analyzing the ontology, and encoding the ontology. We identified the main classes and properties of the domain by investigating classical music recording resources and users' information needs. We implemented the ontology in the Web Ontology Language (OWL) using five steps: transforming the properties, encoding the transformed properties, defining ranges of the properties, constructing individuals, and standardizing the ontology. In constructing the online catalog, we first designed the structure and functions of the catalog based on investigations into users' information needs and information-seeking behaviors. Then we extracted classes and properties of the ontology using the Apache Jena application programming interface (API), and constructed a catalog in the Java environment. The catalog provides a hierarchical main page (built using the Functional Requirements for Bibliographic Records (FRBR) model), a classical music information network and integrated information service; this combination of features greatly eases the task of finding classical music recordings and more information about classical music.

    Abstract
    We are in 2013, and multiword expressions have been around for a while in the computational linguistics research community. Since the first ACL workshop on MWEs 12 years ago in Sapporo, Japan, much has been discussed, proposed, experimented, evaluated and argued about MWEs. And yet, they deserve the publication of a whole special issue of the ACM Transactions on Speech and Language Processing. But what is it about multiword expressions that keeps them in fashion? Who are the people and the institutions who perform and publish groundbreaking fundamental and applied research in this field? What is the place and the relevance of our lively research community in the bigger picture of computational linguistics? Where do we come from as a community, and most importantly, where are we heading? In this introductory article, we share our point of view about the answers to these questions and introduce the articles that compose the current special issue.
