Discussion on the Article “On Ontological Foundations of Conceptual Modelling” by Boris Wyssusek
In this debate paper we follow up on the argumentation given by Boris Wyssusek, who criticizes the use of the BWW-ontology as a foundation of conceptual modelling. In addition, we mention some other possible foundations for conceptual modelling. We have over many years looked at the area of semiotics, given our social constructivistic view of modelling, and we give a brief overview of how semiotics relates to the ontological approach. Finally, we describe some of our practical experiences with the semiotic approach for evaluating modelling languages in an industrial setting
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Methodologische Aspekte der Organisationsmodellierung: Eine soziopragmatisch-konstruktivistische Perspektive
Variations on the Author
“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
We 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
We 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
Ontology and Ontologies in Information Systems Analysis and Design: A Critique
Ontology and the concept of ontologies have attracted considerable attention in the context of research on information systems analysis and design. Being rooted in philosophy, both ontology and the concept of ontologies bear their own history of philosophical debates which have quite often been ignored when applied in the field of information systems. In this contribution it is claimed that a more comprehensive discussion of well-known philosophical issues of ontology and ontologies will help us not only to understand the scope of their applicability in the context of information systems analysis and design. It will also provide us with insights about limitations as well as with directions for issues in need of further research. The argument is critical yet affirmative. It aims at the expansion of the scope of current discourses and focuses especially on socio-philosophical aspects that need to be addressed in order to leverage the full potential of using ontology and ontologies for the provision of a theoretical foundation for information systems analysis and design.
