Scale-free collaboration networks: An author name disambiguation perspective [article]

Jinseok Kim
2018 pre-print
This study argues that collaboration networks can look more or less scale-free depending on the methods for resolving author name ambiguity in bibliographic data.  ...  Analyzing networks constructed from multiple datasets containing 3.4M 9.6M publication records, this study shows that collaboration networks in which author names are disambiguated by the commonly used  ...  Serving as evidence of scale-free social networks, the aggregated findings of scale-free-ness in collaboration networks have formed an important basis of various efforts to model human interaction patterns  ...

Mining and Analyzing Academic Social Networks

Tasleem Arif
2015 International Journal of Computer Applications Technology and Research  
Of all types of possible academic and research collaborations, co-authorship is best documented.  ...  Academics establish relationships by way of various interactions like jointly authoring a research paper or report, jointly supervising a thesis, working jointly on a project, etc.  ...  Removal of duplicates or name disambiguation plays an important role in efficient analysis of publications data.  ...

Distortive effects of initial-based name disambiguation on measurements of large-scale coauthorship networks

Jinseok Kim, Jana Diesner
2015 Journal of the Association for Information Science and Technology  
Scholars have often relied on name initials to resolve name ambiguities in large-scale coauthorship network research.  ...  Also, on average, more than half of top 10 productive or collaborative authors drop off the lists.  ...  Such a mechanism was shown to lead to a scale-free network, where the distribution of node degree follows a power law.  ...

with properties that are explained by both the small-world and the free-scale model.  ...  One of the conclusions of the research is that the researchers under study publish in a similar proportion individually or collaboratively, configuring a fragmented co-authorship network with a main component  ...  In some of them, it implied correcting the disambiguation of their names as authors, that is, the records were checked to see the variations of the names of the authors as well as the incorrect characters  ...

Tie Persistence in Academic Social Networks

Djamila Mohdeb, Abdelhak Boubetra, Mourad Charikhi
2016 Informatica (Ljubljana, Tiskana izd.)  
Our purpose is to assess the extent to which the frequency of the tie, the academic closeness between its actors, and the scientific contributions of the actors in the tie can affect the scientific collaboration  ...  We experimented the model on a social network extracted from the DBLP computer science bibliographic network. We compared the output of the model with that of the link prediction baseline methods.  ...  They are also scale free following a power law in several node properties and their structures are affected by the preferential attachment phenomenon [18, 37] .  ...

Identifying and improving AGU collaborations using network analysis and scientometrics

Tom Narock, Sarah Hasnain, Ronie Stephan
2019 Geoscience Communication  
We are interested in the AGU network structure and what its properties can tell us about how the procedures of the AGU Fall Meeting can be enhanced to facilitate better scientific communication and collaboration  ...  </strong> The American Geophysical Union (AGU) is an Earth and space science professional society based in the United States.  ...  Eric's work was made possible through an ESIP mini-grant. The work ESIP enabled, and Eric's early discussions with the first author, helped lay the groundwork for the research presented here.  ...

Social Centralization and Semantic Collapse: Hyperbolic Embeddings of Networks and Text [article]

Linzhuo Li, Lingfei Wu, James Allen Evans
2020 arXiv   pre-print
We illustrate this method by examining the relationship between social centralization and semantic diversity within 21st Century physics, empirically demonstrating how dense, centralized collaboration  ...  We discuss the complex of causes underlying this association, and theorize the dynamic interplay between structural centralization and semantic contraction, arguing that it introduces an essential tension  ...  Name disambiguation of authors and institutions In order to disambiguate WoS authors we use a hybrid algorithm.  ...

Predicting scientific success based on coauthorship networks

Emre Sarigöl, René Pfitzner, Ingo Scholtes, Antonios Garas, Frank Schweitzer
2014 EPJ Data Science  
Analyzing a data set of over 100,000 publications from the field of Computer Science, we study how centrality in the coauthorship network differs between authors who have highly cited papers and those  ...  We further show that a Machine Learning classifier, based only on coauthorship network centrality metrics measured at the time of publication, is able to predict with high precision whether an article  ...  Each publication record contains a list of author IDs, which, by means of disambiguation heuristics internally applied by the MSAS service, uniquely identify authors independent of name spelling variations  ...
