# Studying the emerging global brain: Analyzing and visualizing the impact of co-authorship teams

@article{Brner2005StudyingTE, title={Studying the emerging global brain: Analyzing and visualizing the impact of co-authorship teams}, author={Katy B{\"o}rner and Luca Dall’Asta and Weimao Ke and Alessandro Vespignani}, journal={Complex.}, year={2005}, volume={10}, pages={57-67} }

This article 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 articles published by 1036 unique… Expand

Influence of co-authorship networks in the research impact: Ego network analyses from Microsoft Academic Search

- Computer Science
- J. Informetrics
- 2014

Results show that tiny and sparse networks achieved more citations per document than dense and compact networks – described by a high Clustering coefficient and a high Average degree – suggesting that in sparse ego networks, the central author have more control on their collaborators being more selective in their recruitment and concluding that this behaviour has positive implications in the research impact.

A bibliometric analysis of Spanish scientific production in these areas of research between 1995 and 2005 as listed in Thomson Reuters’ Science Citation Index Expanded identifies the centres of greatest prestige from the standpoint of co-authorship of scientific papers. Expand

A measure of authors’ centrality in co-authorship networks based on the distribution of collaborative relationships

- Mathematics, Computer Science
- Scientometrics
- 2008

A new measure termed extensity centrality is proposed, taking into account the distribution of an author’s collaborative relationships, and the strength of collaborative ties is chosen, which is closely related to Salton's measure. Expand

The specific shapes of gender imbalance in scientific authorships: A network approach

- Psychology, Computer Science
- J. Informetrics
- 2017

This work finds enough evidence that gender imbalance in scientific authorships brings a peculiar trait to the networks induced from papers published in Web of Science indexed journals of Economics over the period 2010–2015 and having at least one author affiliated to a Portuguese institution.

Uncovering mechanisms of co-authorship evolution by multirelations-based link prediction

- Computer Science
- Inf. Process. Manag.
- 2017

An improved meta-path based model called multirelations-based link prediction in heterogeneous bibliographic network and quantitatively evaluates predictors via link prediction is proposed, which shows that the most appropriate mechanism is a hybrid mechanism denoted by a combination of predictors with weights.

Self-citations, co-authorships and keywords: A new approach to scientists’ field mobility?

- Computer Science
- Scientometrics
- 2007

It is shown that author’s self-citation patterns reveal important information on the development and emergence of new research topics over time, and a network based definition of field mobility is introduced, using the Optimal Percolation Method. Expand

A scientometrics law about co-authors and their ranking: the co-author core

- Mathematics, Sociology
- Scientometrics
- 2012

This paper very briefly examines bibliometric laws, like the h-index and subsequent debate about co-authorship effects, but on the other hand, proposes a measure of collaborative work through a new index, based on data about the publication output of a specific research group. Expand

Visualizing collaboration: Central authors and strong ties in evolutionary game theory

- Computer Science
- ASIST
- 2011

Co-authorship patterns in 753 articles with two or more authors in the literature of Evolutionary Game Theory, were examined using social network analysis tools to identify co- author network structures worthy of additional investigation. Expand
