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

Generally, open science practices are only slowly having an impact on mainstream archaeological practice. An exception is the open access to publications, which, together with open data and open methodologies may represent those practices most relevant for archaeological researchers. This article introduces a selection of archaeology projects that embrace and facilitate open science practices. Finally there will be a discussion of some of the questions and challenges the discipline is facing in its move towards an Open Archaeology.

Abstract

The social dynamics of alternative facts: why what you believe depends on who you know. Why should we care about having true beliefs? And why do demonstrably false beliefs persist and spread despite bad, even fatal, consequences for the people who hold them? Philosophers of science Cailin OConnor and James Weatherall argue that social factors, rather than individual psychology, are whats essential to understanding the spread and persistence of false beliefs. It might seem that theres an obvious reason that true beliefs matter: false beliefs will hurt you. But if thats right, then why is it (apparently) irrelevant to many people whether they believe true things or not? The Misinformation Age, written for a political era riven by fake news, alternative facts, and disputes over the validity of everything from climate change to the size of inauguration crowds, shows convincingly that what you believe depends on who you know. If social forces explain the persistence of false belief, we must understand how those forces work in order to fight misinformation effectively.

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

This study examined how researchers used research information systems (RIMSs) and the relationships among researchers' seniority, discipline, and types and extent of RIMS use. Most researchers used RIMSs to discover research content. Fewer used RIMSs for sharing and promoting their research. Early career researchers were more frequent users of RIMSs than were associate and full professors. Likewise, assistant professors and postdocs exhibited a higher probability of using RIMSs to promote their research than did students and full professors. Humanities researchers were the least frequent users of RIMSs. Moreover, humanities scholars used RIMSs to evaluate research less than did scholars in other disciplines. The tasks of discovering papers, monitoring the literature, identifying potential collaborators, and promoting research were predictors of higher RIMS use. Researchers who engaged in promoting their research, evaluating research, or monitoring the literature showed a greater propensity to have a public RIMS profile. Furthermore, researchers mostly agreed that not being required, having no effect on their status, not being useful, or not being a norm were reasons for not having a public RIMS profile. Humanities scholars were also more likely than social scientists to agree that having a RIMS profile was not a norm in their fields.

Abstract

A journal may be considered as having dimension-specific prestige when its score, based on a given journal ranking model, exceeds a threshold value. But a journal has multidimensional prestige only if it is a prestigious journal with respect to a number of dimensions-e.g., Institute for Scientific Information Impact Factor, immediacy index, eigenfactor score, and article influence score. The multidimensional prestige of influential journals takes into account the fact that several prestige indicators should be used for a distinct analysis of the impact of scholarly journals in a subject category. After having identified the multidimensionally influential journals, their prestige scores can be aggregated to produce a summary measure of multidimensional prestige for a subject category, which satisfies numerous properties. Using this measure of multidimensional prestige to rank subject categories, we have found the top scientific subject categories of Web of Knowledge as of 2010.

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

Purpose - This paper aims to report an empirical study of the information-related behaviour of emerging artists and designers. It also aims to add to understanding of the information behaviour of the group both as practising artists (a little understood category of information users), and also as "new practitioners". Design/methodology/approach - A literature analysis is used to guide creation of an online questionnaire, eliciting both qualitative and quantitative data. A total of 78 practising artists participated, all having graduated in the seven years prior to the survey. Findings - The group have generally the same information practices as more established artists. They place reliance on internet and social networks, while also using traditional printed tools and libraries. Browsing is important, but not a predominant means of accessing information. Inspiration is found from a very diverse and idiosyncratic set of sources, often by serendipitous means. Their status as emergent practitioners means that their information behaviour is governed by cost factors, and by needs for career advice and interaction with peers. Research limitations/implications - The study group are a convenience sample, all having access to the internet. No observation or interviews were carried out. Practical implications - The results will provide guidance to academic and public librarians serving artist users, and to those providing career advice to them. It will also be valuable to those providing services to "new practitioners" in any field. Originality/value - This is one of a very few papers reporting empirical studies of the information behaviour of artists, and has the largest sample size of any such study. It is one of a very few papers considering the information needs and behaviour of new practitioners.

Abstract

There are quite a few success stories illustrating philosophy's relevance to information science. One can cite, for example, Leibniz's work on a characteristica universalis and a corresponding calculus ratiocinator through which he aspired to reduce reasoning to calculating. It goes without saying that formal logic initiated research on decidability and computational complexity. But even beyond the realm of formal logic, philosophy has served as a source of inspiration for developments in information and computer science. At the end of the twentieth century, formal ontology emerged from a quest for a semantic foundation of information systems having a higher reusability than systems being available at the time. A success story that is less well documented is the advent of frame systems in computer science. Minsky is credited with having laid out the foundational ideas of such systems. There, the logic programming approach to knowledge representation is criticized by arguing that one should be more careful about the way human beings recognize objects and situations. Notably, the paper draws heavily on the writings of Kuhn and the Gestalt-theorists. It is not our intent, however, to document the traces of the frame idea in the works of philosophers. What follows is, rather, an exposition of a methodology for representing scientific knowledge that is essentially frame-like. This methodology is labelled as structuralist theory of science or, in short, as structuralism. The frame-like character of its basic meta-theoretical concepts makes structuralism likely to be useful in knowledge representation.

Abstract

This article addresses the question "what is information?" by comparing the meaning of the term "information" and epistemological assumptions of three theories in library and information science: the "Shannon-Weaver model," Brookes' interpretation of Popper's World 3, and the Data-Information-Knowledge-Wisdom model. It shows that the term "information" in these theories refers to empirical entities or events and is conceptualized as having causal powers upon human minds. It is argued that the epistemological assumptions have led to the negligence of the cultural and social aspects of the constitution of information (i.e., how something is considered to be and not to be information) and the unquestioned nature of science in research methodologies.

Abstract

The key argument of this paper is that the field of knowledge organization can potentially provide a powerful - and indeed the only powerful - response to the skeptical claims that are common in the contemporary academy. Though skeptical arguments have an important place in our field - the present author readily confesses to having learned much in responding to such arguments - it would be unfortunate if the field of knowledge organization were to assume the correctness of a skeptical outlook. Rather, the field should essay to combat the sources of skepticism. Strategies for doing so are outlined.

Abstract

We posit that the well-established interaction type "toolbox" currently providing the four interaction types Instructing, Conversing, Manipulating, and Exploring should be expanded to include a fifth interaction type, Responding, that accounts for user engagements in response to a system-initiated engagement request. This expansion reflects that increasingly, smart systems request input from users without having been prompted by them, which is the essence of the existing interaction types. Systems utilizing the Responding interaction type proactively seek input from users in situations where said input is required.

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

Support for explicit collaboration in information-seeking activities is increasingly recognized as a desideratum for search systems. Several tools have emerged recently that help groups of people with the same information-seeking goals to work together. Many issues for these collaborative information-seeking (CIS) environments remain understudied. The authors identified awareness as one of these issues in CIS, and they presented a user study that involved 42 pairs of participants, who worked in collaboration over 2 sessions with 3 instances of the authors' CIS system for exploratory search. They showed that while having awareness of personal actions and history is important for exploratory search tasks spanning multiple sessions, support for group awareness is even more significant for effective collaboration. In addition, they showed that support for such group awareness can be provided without compromising usability or introducing additional load on the users.

Abstract

User-centered analysis can benefit the development of interactive video digital libraries. Findings from this study support the idea that having additional understanding about the intended users of video digital libraries can help researchers match system designs with the envisioned use of prototype systems. This study examines one user-centered factor specifically, familiarity with visual search topics, to explore if and how this may be associated with other factors within an interactive video retrieval context. Twenty-eight users from the field of science education were recruited to complete six visual search topics using a prototype system to retrieve video clips from a collection of NASA Science Education Programs. Analysis revealed that topic familiarity was associated with other factors that were examined throughout this study, including user-assessed and experimenter-assessed topic completion ratios, opinions of the prototype system, and interaction behaviors. Such results can have a variety of implications for developing video digital libraries, especially those designed to support queries and interactions of knowledgeable users from a defined domain.

Abstract

Given their ease of use and capability for interactivity, new media are seen as having the potential to make visible previously marginalized voices. The online presence of the writing of history is increasing, and this potential would be a welcome development for the field as it would create a much richer set of easily available historical perspectives. However, this article suggests that the achievement of this promise is fraught with difficulty and that a more likely outcome is a mapping of the status quo in historical representation onto the new media. To illustrate this, I present an analysis of the Wikipedia accounts of Singaporean and Philippine history. For Singapore, alternative historical visions are not as developed as those for the Philippines, and this is reflected in the nature of the respective Wikipedia accounts. I suggest that a possible means to achieve something more of the promise of digital media for history is for information professionals to take a keener interest in Wikipedia, with an eye to helping include accounts of documented historical perspectives that are ignored by mainstream historiographical traditions.

Abstract

In an effort to understand how academic scientists seek information relevant to their research in today's environment of ubiquitous electronic access, a correlation framework is built and regression analysis is applied to the survey results from 2,063 academic researchers in natural science, engineering, and medical science at five research universities in the United States. Previous work has reported descriptive statistics about these scientists' information-seeking behavior. This study extends that work to examine relationships between scientists' information-seeking behaviors and their personal and environmental factors. Several regression models, including the Poisson model, the logit model, and the ordered logit model, are built to interpret the correlation among scientists' behaviors. In addition, exploratory factor analysis is used for data reduction. Overall, many factors were found to affect the specific information-seeking behaviors of scientists, including demographic, psychological, role-related, and environmental factors. Of the factors having an effect, academic position was the most important determinant of information behavior.

Abstract

This article presents a new idea on shelving printed books and finding books in libraries. The author advocates that traditional book classification number (TBCN) systems should be replaced by a better indexing method for books in libraries. The author proposes a new way of seeking books for library users wishing to locate them called a 'dynamic book subject number' (DBSN) system. The new system combines new indexing rules and automated system technology to create settings in which a book's 'subject number' can change rather than having a particular permanent classification number assigned to it. The new way encourages library users to seek books through a user-friendly cataloging system by choosing subjects from the embedded database. The database contains thousands of subjects with their corresponding Arabic codes. For printed books, the DBSN ushers in a new era in the relationship between library users and the books.
