Abstract

Die Bereitstellung und Nutzung digitaler Bibliotheken entwickelt sich allmählich zum Standard der Literatur und Informationsversorgung in Wissenschaft und Forschung. Ganzen Disziplinen genügt oftmals die verfügbare digitale Information, Printmedien werden besonders im STM-Segment zu einem Nischenprodukt. Digitale Texte können beliebig eingebaut, kopiert und nachgenutzt werden, die Verlinkung zwischen Metadaten und Volltexten bringt weitere Nutzungsvorteile. Dabei sind die Angebote von Digital Libraries Bestandteil eines ganzheitlichen digitalen Ansatzes, wonach die elektronische Informations- und Literaturversorgung integraler Bestandteil von E-Science (Enhanced Science) oder Cyberinfrastructure darstellt. Hierbei verschmelzen dann Produktion, Diskussion, Distribution und Rezeption der wissenschaftlichen Inhalte auf einer einzigen digitalen Plattform. Damit sind dann nicht nur die Literatur- und Informationsversorgung (Digital Libraries), sondern auch die Wissenschaft selbst digital geworden. Diese dramatische Veränderung in der Wissenschaftskommunikation hat direkte Auswirkungen auf die Messung der Wissenschaftskommunikation, also auf die Evaluation von wissenschaftlichem Output. Bisherige Systeme der Wissenschaftsvermessung basieren hauptsächlich auf bibliometrischen Analysen, d.h. der Quantifizierung des Outputs und dessen Rezeption (Zitierhäufigkeit). Basis dafür sind insbesondere im STM-Bereich die international anerkannten Datenbanken des ISI (Thomson Scientific) insbesondere der Science Citation Index, SCI) oder vielleicht zukünftig das Konkurrenzprodukt SCOPUS des Wissenschaftskonzerns Reed Elsevier. Die Digitalisierung der Wissenschaft in ihrem kompletten Lebenszyklus, die zunehmende Nutzung und Akzeptanz von Dokumentenrepositorien, Institutsservern und anderen elektronischen Publikationsformen im Rahmen von E-Science erfordern und ermöglichen zugleich den Nachweis von Output und Rezeption durch neue bibliometrische Formen, etwa der Webometrie (Webmetrics). Im vorliegenden Paper haben wir hierzu Analysen durchgeführt und stellen eine Abschätzung vor, wie sich der Anteil von webometrisch erfassbarer und zugänglicher wissenschaftlicher Literatur im Vergleich zu Literatur, die mit den Standardsystemen nachgewiesen werden kann im Laufe der letzten Jahre verändert hat. Dabei haben wir unterschiedliche Disziplinen und Länder berücksichtigt. Zudem wird ein Vergleich der webometrischen Nachweisqualität so unterschiedlicher Systeme wie SCI, SCOPUS und Google Scholar vorgestellt.

Abstract

Information grounds emerge as people share information with others in a common place. Many studies have investigated the emergence of information grounds in public places. This study pays attention to the emergence, peak, and abeyance of an online information ground. It investigates a Facebook group used by youth for sharing information when misinformation spread wildly during the 2011 violence in Ambon, Indonesia. The findings demonstrate change and continuity in an online information ground; it became an information hub when reaching a peak cycle, and an information repository when entering into abeyance. Despite this period of nonactivity, the friendships and collective memories resulting from information ground interactions last over time and can be used for reactivating the online information ground when new needs emerge. Illuminating the lifecycles of an online information ground, the findings have potential to explain the dynamic of users' interactions with others and with information in quotidian spaces.

Abstract

Information scattering is an often observed phenomenon related to information collections where there are a few sources that have many items of relevant information about a topic, while most sources have only a few. This entry discusses the original discovery of the phenomenon, the types of information scattering observed across many different information collections, methods that have been used to analyze the phenomenon, explanations for why and how information scattering occurs, and how these results have informed the design of systems and search strategies. The entry concludes with future challenges related to building computational models to more precisely describe the process of information scatter, and algorithms which help users to gather highly scattered information.

Abstract

Draws attention to the vast potential of online information databases and to the many new possibilities which advanced search techniques offer those who want to explore databases. Looks at informetrics, an emerging subfield in information science, which is based on the combination of advanced information retrieval and quantitative studies of information flow. Describes 3 studies carried out at the Centre for Information studies at the Royal School of Library and Information Science in Copenhagen, Denmark, to illustrate the scope and nature of informetric analysis

Abstract

A scientometric model (ISI-S model) is introduced for describing the institutionalization process of scientific information. The central concept of ISI-S is that the scientific information published may develop with time through permanent evaluation and modification processes toward a cognitive consensus of distinguished authors of the respective scientific field or discipline. ISI-S describes the information and knowledge systems of science as a global network of interdependent information and knowledge clusters that are dynamically changing by their content and size. ISI-S assumes sets of information with short- or long-term impact and information integrated into the basic scientific knowledge or common knowledge. The type of the information sources (e.g., lecture, journal paper, review, monograph, book, textbook, lexicon) and the length of the impact are related to the grade of institutionalization. References are considered as proofs of manifested impact. The relative and absolute development of scientific knowledge seems to be slower than the increase of the number of publications.

Abstract

This entry presents an account of the core concerns of information science through such means as definitional sketches, identification of themes, historical notes, and bibliometric evidence, including a citation-based map of 121 prominent information scientists of the twentieth century. The attempt throughout is to give concrete and pithy descriptions, to provide numerous specific examples, and to take a critical view of certain received language and ideas in library and information science.

Abstract

This article first analyzes library and information science (LIS) research articles published in core LIS journals in 2005. It also examines the development of LIS from 1965 to 2005 in light of comparable data sets for 1965, 1985, and 2005. In both cases, the authors report (a) how the research articles are distributed by topic and (b) what approaches, research strategies, and methods were applied in the articles. In 2005, the largest research areas in LIS by this measure were information storage and retrieval, scientific communication, library and information-service activities, and information seeking. The same research areas constituted the quantitative core of LIS in the previous years since 1965. Information retrieval has been the most popular area of research over the years. The proportion of research on library and information-service activities decreased after 1985, but the popularity of information seeking and of scientific communication grew during the period studied. The viewpoint of research has shifted from library and information organizations to end users and development of systems for the latter. The proportion of empirical research strategies was high and rose over time, with the survey method being the single most important method. However, attention to evaluation and experiments increased considerably after 1985. Conceptual research strategies and system analysis, description, and design were quite popular, but declining. The most significant changes from 1965 to 2005 are the decreasing interest in library and information-service activities and the growth of research into information seeking and scientific communication.
