Co-Authorship Patterns and Networks in Pharmacology and Pharmacy in Iran
This study aimed at investigating scientific collaboration and analyzing co-authorship networks in pharmacology and pharmacy research studies in Iran. Data used for this scientometric study included all pharmacology and pharmacy documents of Iran, indexed in Web of Science (WOS) from 2003 to 2014 and were analyzed using citation analysis section of WOS and Excell and SPSS. Citespace, and Gephi softwares were used for visualization and analysis of co-authorship network. The dominant co-authorship pattern was four-author pattern, with collaboration index, degree of collaboration and collaboration coefficient of 4.49, 0.96 and 0.691 respectively. The obtained density for co-authorship network and the clustering coefficient mean were 0.3 and 0.306 respectively. Despite the fact that the collaboration index in the field of pharmacology and pharmacy was much greater compared to other fields, the networks' total average density signified a great sparseness of co-authorship network. The clustering coefficient mean indicated that the network members' tendency towards forming different clusters was relatively low. There was no meaningful relationship between collaboration index and the number of productions as well as collaboration index and the citation impact. Authors indicated a greater tendency towards co-authorship. It is recommended that senior officials in scientific communities pay more attention to scientific collaboration activities, allocation of budget and appropriate facilities, and providing suitable circumstance to encourage more collaboration. It is recommended also, researchers pay more attention to constant team working with colleagues and students
Studying the Emerging Global Brain: Analyzing and Visualizing the Impact of Co-Authorship Teams
This paper introduces a suite of approaches and measures to study the impact
of co-authorship teams based on the number of publications and their citations
on a local and global scale. In particular, we present a novel weighted graph
representation that encodes coupled author-paper networks as a weighted
co-authorship graph. This weighted graph representation is applied to a dataset
that captures the emergence of a new field of science and comprises 614 papers
published by 1,036 unique authors between 1974 and 2004. In order to
characterize the properties and evolution of this field we first use four
different measures of centrality to identify the impact of authors. A global
statistical analysis is performed to characterize the distribution of paper
production and paper citations and its correlation with the co-authorship team
size. The size of co-authorship clusters over time is examined. Finally, a
novel local, author-centered measure based on entropy is applied to determine
the global evolution of the field and the identification of the contribution of
a single author's impact across all of its co-authorship relations. A
visualization of the growth of the weighted co-author network and the results
obtained from the statistical analysis indicate a drift towards a more
cooperative, global collaboration process as the main drive in the production
of scientific knowledge.Comment: 13 pages, 9 figure
Opinion mining and sentiment analysis in marketing communications: a science mapping analysis in Web of Science (1998–2018)
Opinion mining and sentiment analysis has become ubiquitous in our society, with
applications in online searching, computer vision, image understanding, artificial intelligence and
marketing communications (MarCom). Within this context, opinion mining and sentiment analysis
in marketing communications (OMSAMC) has a strong role in the development of the field by
allowing us to understand whether people are satisfied or dissatisfied with our service or product
in order to subsequently analyze the strengths and weaknesses of those consumer experiences. To
the best of our knowledge, there is no science mapping analysis covering the research about opinion
mining and sentiment analysis in the MarCom ecosystem. In this study, we perform a science
mapping analysis on the OMSAMC research, in order to provide an overview of the scientific work
during the last two decades in this interdisciplinary area and to show trends that could be the basis
for future developments in the field. This study was carried out using VOSviewer, CitNetExplorer
and InCites based on results from Web of Science (WoS). The results of this analysis show the
evolution of the field, by highlighting the most notable authors, institutions, keywords,
publications, countries, categories and journals.The research was funded by Programa Operativo FEDER Andalucía 2014‐2020, grant number “La

The Extraction of Community Structures from Publication Networks to Support Ethnographic Observations of Field Differences in Scientific Communication
The scientific community of researchers in a research specialty is an
important unit of analysis for understanding the field specific shaping of
scientific communication practices. These scientific communities are, however,
a challenging unit of analysis to capture and compare because they overlap,
have fuzzy boundaries, and evolve over time. We describe a network analytic
approach that reveals the complexities of these communities through examination
of their publication networks in combination with insights from ethnographic
field studies. We suggest that the structures revealed indicate overlapping
sub- communities within a research specialty and we provide evidence that they
differ in disciplinary orientation and research practices. By mapping the
community structures of scientific fields we aim to increase confidence about
the domain of validity of ethnographic observations as well as of collaborative
patterns extracted from publication networks thereby enabling the systematic
study of field differences. The network analytic methods presented include
methods to optimize the delineation of a bibliographic data set in order to
adequately represent a research specialty, and methods to extract community
structures from this data. We demonstrate the application of these methods in a
case study of two research specialties in the physical and chemical sciences.Comment: Accepted for publication in JASIS
Tracing scientific influence
Scientometrics is the field of quantitative studies of scholarly activity. It
has been used for systematic studies of the fundamentals of scholarly practice
as well as for evaluation purposes. Although advocated from the very beginning
the use of scientometrics as an additional method for science history is still
under explored. In this paper we show how a scientometric analysis can be used
to shed light on the reception history of certain outstanding scholars. As a
case, we look into citation patterns of a specific paper by the American
sociologist Robert K. Merton.Comment: 25 pages LaTe
Does your surname affect the citability of your publications?
Prior investigations have offered contrasting results on a troubling
question: whether the alphabetical ordering of bylines confers citation
advantages on those authors whose surnames put them first in the list. The
previous studies analyzed the surname effect at publication level, i.e. whether
papers with the first author early in the alphabet trigger more citations than
papers with a first author late in the alphabet. We adopt instead a different
approach, by analyzing the surname effect on citability at the individual
level, i.e. whether authors with alphabetically earlier surnames result as
being more cited. Examining the question at both the overall and discipline
levels, the analysis finds no evidence whatsoever that alphabetically earlier
surnames gain advantage. The same lack of evidence occurs for the subpopulation
of scientists with very high publication rates, where alphabetical advantage
might gain more ground. The field of observation consists of 14,467 scientists
in the sciences
