Abstract

Wikipedia is increasingly an important source of information for many. Hence, it is important to develop an understanding of how it is situated within society and the wider roles it is called onto perform. This article argues that one of these roles is as a depository of collective memory. Building on the work of Pentzold, I present a case study of the English Wikipedia article on the Vietnam War to demonstrate that the article, or more accurately, its talk pages, provide a forum for the contestation of collective memory. I further argue that this function is one that should be supported by libraries as they position themselves within a rapidly changing digital world.

Abstract

Die Wikipedia ist sowohl hinsichtlich ihres Umfangs als auch hinsichtlich ihrer Nutzung die heute bedeutendste Enzyklopädie. Auch innerhalb der Wissenschaft spielt sie, vor allem als leicht zugänglicher Rechercheeinstieg, eine wichtige Rolle. In diesem Zusammenhang steht die Glaubwürdigkeit der Wikipedia immer wieder im Fokus, da ihre Inhalte nicht durch Fachexperten kontrolliert, sondern von jedermann ediert werden können. Jedoch ist innerhalb der Wikipediacommunity ein starkes Bemühen um Glaubwürdigkeit festzustellen. Anhand der Analyse ausgewählter Redaktionsprinzipien der Wikipedia und der Auswertung einer Fallstudie zur Erzeugung von Glaubwürdigkeit in der deutschsprachigen Wikipedia lassen sich Implikationen für Information Professionals ableiten. Besonders Bibliothekarinnen und Bibliothekare können durch ihren Zugang zu Literatur einerseits und mit ihren Recherchekenntnissen andererseits dabei helfen, die Glaubwürdigkeit der Wikipedia zu steigern.

Abstract

With the rise of Wikipedia as a first-stop source for scientific information, it is important to understand whether Wikipedia draws upon the research that scientists value most. Here we identify the 250 most heavily used journals in each of 26 research fields (4,721 journals, 19.4M articles) indexed by the Scopus database, and test whether topic, academic status, and accessibility make articles from these journals more or less likely to be referenced on Wikipedia. We find that a journal's academic status (impact factor) and accessibility (open access policy) both strongly increase the probability of it being referenced on Wikipedia. Controlling for field and impact factor, the odds that an open access journal is referenced on the English Wikipedia are 47% higher compared to paywall journals. These findings provide evidence is that a major consequence of open access policies is to significantly amplify the diffusion of science, through an intermediary like Wikipedia, to a broad audience.

Abstract

This study evaluates how well the authors of Wikipedia history articles adhere to the site's policy of assuring verifiability through citations. It does so by examining the references and citations of a subset of country histories. The findings paint a dismal picture. Not only are many claims not verified through citations, those that are suffer from the choice of references used. Many of these are from only a few US government Websites or news media and few are to academic journal material. Given these results, one response would be to declare Wikipedia unsuitable for serious reference work. But another option emerges when we jettison technological determinism and look at Wikipedia as a product of a wider social context. Key to this context is a world in which information is bottled up as commodities requiring payment for access. Equally important is the problematic assumption that texts are undifferentiated bearers of knowledge. Those involved in instructional programs can draw attention to the social nature of texts to counter these assumptions and by so doing create an awareness for a new generation of Wikipedians and Wikipedia users of the need to evaluate texts (and hence citations) in light of the social context of their production and use.

Abstract

Using the Arts & Humanities Citation Index (A&HCI) 2008, we apply mapping techniques previously developed for mapping journal structures in the Science and Social Sciences Citation Indices. Citation relations among the 110,718 records were aggregated at the level of 1,157 journals specific to the A&HCI, and the journal structures are questioned on whether a cognitive structure can be reconstructed and visualized. Both cosine-normalization (bottom up) and factor analysis (top down) suggest a division into approximately 12 subsets. The relations among these subsets are explored using various visualization techniques. However, we were not able to retrieve this structure using the Institute for Scientific Information Subject Categories, including the 25 categories that are specific to the A&HCI. We discuss options for validation such as against the categories of the Humanities Indicators of the American Academy of Arts and Sciences, the panel structure of the European Reference Index for the Humanities, and compare our results with the curriculum organization of the Humanities Section of the College of Letters and Sciences of the University of California at Los Angeles as an example of institutional organization.

Abstract

The purpose of this research was to establish an upper bound on finding answers to health-related questions in MedlinePlus and other online resources. Seven reference librarians tested a set of protocols to determine whether it was possible to use the types and foci of the questions extracted from customer requests submitted to the National Library of Medicine to find authoritative answers to these questions. Librarians tested the protocols manually to determine if the process was sufficiently robust and accurate to later automate. Results indicated that the extracted terms provide enough information to find authoritative answers for about 60% of questions and that certain question types are more likely to result in authoritative answers than others. The question corpus and analysis performed for this project will inform automatic question answering systems, and could lead to suggestions for new content to include in MedlinePlus. This approach can serve as an example to researchers interested in methods of evaluating question answering tools and the contents of online databases.

Abstract

Mit Start des Sommersemesters ist adlr.link, der Fachinformationsdienst für die Medien- und Kommunikationswissenschaften nun für alle interessierten Wissenschaftlerinnen und Wissenschaftler verfügbar. Unter http://adlr.link können alle Forschenden aus der Fachcommunity und den angrenzenden Fachgebieten unser Portal zur Recherche nutzen und sich für die Nutzung kostenlos registrieren. Weitere Informationen habe ich Ihnen hier in einem Flyer zusammengestellt. http://blog.adlr.link/wp-content/uploads/2016/04/adlr-Flyer-Web.pdf. Auf unserem Portal finden Sie zudem unter "Blog" eine Blogseite mit aktuellen Neuerungen, einer umfangreichen FAQ-Seite und der Möglichkeit, sich für den Newsletter anzumelden. Zunächst ist die Recherche in über 700.000 Zeitschriftenartikeln, gedruckten oder online verfügbaren Monografien und Sammelwerken, Open Access-Dokumenten und audiovisuellen Quellen möglich. Zudem bieten wir einen Dokumentenlieferdienst und eine nutzergesteuerte Erwerbung von neu erschienenen Print-Publikationen an. Bei letzterer liefern wir die gewünschten Medien direkt an den jeweiligen Forschenden aus. Wir werden den Dienst in den kommenden Wochen weiter bewerben. Ich würde mich freuen, wenn Sie die Information den jeweiligen Fachreferenten in Ihren Häusern weitergeben könnten und auf unser neues Angebot hinweisen. In diesem Zusammenhang möchte ich darauf hinweisen, dass wir die Dienste der bisherigen ViFa medien bühne film nicht weiter pflegen werden, wenn die Nachfolgeportale in Betrieb sind.
