Academic careers in Computer Science: continuance and transience of lifetime co-authorships

Abstract

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Any correspondance concerning this service should be sent to the repository administrator: staff-oatao@listes-diff.inp-toulouse.fr Abstract Scholarly publications reify fruitful collaborations between co-authors. A branch of research in the Science Studies focuses on analyzing the co-authorship networks of established scientists. Such studies tell us about how their collaborations developed through their careers. This paper updates previous work by reporting a transversal and a longitudinal studies spanning the lifelong careers of a cohort of researchers from the DBLP bibliographic database. We mined 3,860 researchers' publication records to study the evolution patterns of their co-authorships. Two features of co-authors were considered: 1) their expertise, and 2) the history of their partnerships with the sampled researchers. Our findings reveal the ephemeral nature of most collaborations: 70% of the new co-authors were only one-shot partners since they did not appear to collaborate on any further publications. Overall, researchers consistently extended their co-authorships 1) by steadily enrolling beginning researchers (i.e., people who had never published before), and 2) by increasingly working with confirmed researchers with whom they already collaborated.

Social Network Analysis of Scientific Articles Published by Food Policy

“…This conclusion is in line with international literature [33,50], i.e., it shows the importance of cliques and significant authors in a scientific community.…”

“…This collaboration can take various forms (e.g., research projects, publications in peer-reviewed journals or in conference papers). According to [50], collaboration is mostly facilitated by technological advances, geographical proximity, and the similarity of the actual research topics.…”

“…These well-known scientists mostly work as a hub in attracting a large number of researchers from several different universities and research institutions [50]. According to [47], research collaboration increases research quality and leads to more often cited co-authored papers.…”

Author‐based analysis of conference versus journal publication in computer science

“…Also, articles published in 2017 were excluded because records for that year are incomplete due to, for instance, the lag time in publisher indexing. (iii) Following Cabanac, Hubert, and Milard (), articles in CoRR or IACR Cryptology ePrint Archive were excluded. Although they are categorized as journal articles in DBLP, they are not peer‐reviewed, their status (for instance, draft, preprint, or published ones) is unclear, and they often lead to duplicate records (for instance, both a preprint in CoRR and its journal version article are recorded in DBLP).…”

A study of publication trajectories of the Brazilian Computer Science community

“…Figure 3 shows average publication rates per-person not adjusted to inflation, according to prestige ranks. As mentioned by (Arruda et al 2009, Cabanac et al 2015, Cavero et al 2014, counting the total of publications can suffer from overcounting as a publication is counted as many times as the number of authors. This affects Figures 3 and 4.…”
