Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
On the Strong Equivalences for LPMLN Programs
Full text linkLPMLN is a powerful knowledge representation and reasoning tool that combines
the non-monotonic reasoning ability of Answer Set Programming (ASP) and the
probabilistic reasoning ability of Markov Logic Networks (MLN). In this paper,
we study the strong equivalence for LPMLN programs, which is an important tool
for program rewriting and theoretical investigations in the field of logic
programming. First of all, we present the notion of p-strong equivalence for
LPMLN and present a model-theoretical characterization for the notion. And we
investigate the relationships among the p-strong equivalence and other existing
notions of strong equivalences for LPMLN. Then, we investigate several
properties of the p-strong equivalence from the following four aspects.
Firstly, we investigate two relaxed notions of the p-strong equivalence
according to practical scenarios of program rewriting, and present
corresponding characterizations for the notions. Secondly, we analyze the
computational complexities of deciding strong equivalences for LPMLN programs.
Thirdly, we investigate the relationships among the strong equivalences of
LPMLN and two extensions of ASP: ASP with weak constraints and ordered
disjunctions. Finally, we investigate LPMLN program simplification via the
p-strong equivalence and present some syntactic conditions that decide the
p-strong equivalence between a single LPMLN rule and the empty program. The
contributions of the paper are as follows. Firstly, all of the results
presented in this paper provide a better understanding of LPMLN programming,
which helps us further explore the properties of LPMLN. Secondly, the
relationships among the strong equivalences open a way to study the strong
equivalences for some logic formalisms by translating into LPMLN. Thirdly, the
program simplification can be used to enhance the implementations of the LPMLN
solvers ..
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
