Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Kognitive Robotik: Wie KI mit Robotern unsere Zukunft gestalten
No full textWie die Verbindung von Künstlicher Intelligenz und Robotik unser Leben revolutionieren könnte darüber spricht Moderator Sven Oswald mit Expertinnen und Experten der Fraunhofer-Gesellschaft. In dieser Folge geben unsere Fachleute Einblicke in die spannenden Möglichkeiten und Herausforderungen dieser Technologien - von der Industrie über den öffentlichen Raum bis hin zur Medizin.
Dr. Werner Kraus vom Fraunhofer-Institut für Produktionstechnik und Automatisierung IPA erklärt, was kognitive Robotik ist und welche neuen Fähigkeiten Roboter durch Künstliche Intelligenz entwickeln können. Dabei geht er auf aktuelle Beispiele aus der Industrie ein, die bereits von dieser Technologie profitieren.
Dr. Kathrin Pollmann vom Fraunhofer-Institut für Arbeitswirtschaft und Organisation IAO spricht über die Mensch-Roboter-Interaktion und die Herausforderungen, die uns erwarten, wenn Roboter im öffentlichen Raum allgegenwärtig werden, zum Beispiel wie in einem Fraunhofer-Projekt beim Putzen vor dem Bahnhof in Ulm. Sie betont die Bedeutung von Akzeptanz und Kommunikation, um Roboter nahtlos in unseren Alltag zu integrieren.
Prof. Dr. Norbert Elkmann vom Fraunhofer-Institut für Fabrikbetrieb und -automatisierung IFF gibt Einblicke in die Nutzung von Robotern in der Medizin und erläutert, wie Assistenzroboter bereits heute in Krankenhäusern und Pflegeeinrichtungen unterstützen. Er erklärt, wie diese Roboter durch KI noch präziser und patientenfreundlicher werden
Assistenz und Mensch-Roboter-Kollaboration
No full textS.14-15Assistenzroboter stellen eine Zukunftstechnologie bei der Umgestaltung und Optimierung von Produktion und Logistik auf flexiblere und effizientere Prozesse dar. Dabei müssen die geltenden Sicherheitsanforderungen beim Einsatz von Assistenzrobotern im direkten Arbeitsumfeld des Menschen ohne trennende Schutzfelder erfüllt werden. Durch die Stärken der Automatisierungs- und Robotertechnik wie Präzision, hohe Handhabungslasten und ununterbrochener Einsatz mit den motorischen, sensorischen sowie perzeptiven und kognitiven Fähigkeiten des Menschen besteht ein immenses Verbesserungspotenzial für künftige Produktions- und Montagesysteme sowie Logistik.Nr.
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
