"Potenziale semantischer Technologien für die Bibliothek der Zukunft", Klaus Tochtermann
No full textThe European Open Science Cloud
No full textInterview with Klaus Tochtermann, Leibniz Information Centre for Economics, Kiel, Germany, recorded at the BEILSTEIN OPEN SCIENCE SYMPOSIUM (22 – 24 May 2017). Klaus Tochtermann discusses the European Science Cloud (EOSC) with Carsten Kettner. He describes the concept for the ESOC which is planned to connect current and future research data centers with one another in an eco-system of infrastructures. Also discussed are the standards necessary to make such an eco-system function: standards for metadata, standards for APIs and standards for authentication. He stressed the need for scientists to make their data FAIR (findable, accessible, interoperable and reusable), to support cross-disciplinary research and re-use. In the EOSC all data should be FAIR. Klaus mentions that in the opinion of the high level expert group on EOSC, about 80% of the reasons that scientists do not share data are cultural, mainly due to the lack of sufficient incentives

A Semiotic Framework for Ontology Development
No full textWe address the issue of ontology construction and reuse, and regard such
processes as collaborative negotiations among stakeholders. A semiotic framework is
proposed to model the communication environment. Accordingly, content and expression
of an ontology have been clearly distinguished, and formalized independently. A
twofold model is proposed: at an operational level, two stakeholders – such as designer
and user – negotiate by proposing and modifying ontology fragments. At a reflexive
level, the negotiation involves interpretations, until a set of shared meanings is reached;
the process can be described adopting a narrative approach
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
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
