Diversity of Skills and Collective Intelligence in GitHub [article]

Dorota Celińska-Kopczyńska
2021 arXiv   pre-print
In this paper, we investigate the patterns behind the connections among GitHub users in Open Source communities.  ...  We find that diversity of skills plays an essential role in the creation of links among users who exchange information (e.g., in issues, comments, and following networks).  ...  In theory, there can be even networks that exhibit both disassortativity and rich-club behavior.  ...

Coding Together at Scale: GitHub as a Collaborative Social Network [article]

Antonio Lima, Luca Rossi, Mirco Musolesi
2014 arXiv   pre-print
GitHub is the most popular repository for open source code. It has more than 3.5 million users, as the company declared in April 2013, and more than 10 million repositories, as of December 2013.  ...  We show that the distributions of the number of contributors per project, watchers per project and followers per user show a power-law-like shape.  ...  The two networks show remarkably different rich-club behaviors, due to their distinct nature. rich-club phenomenon.  ...

Graph analysis of network flow connectivity behaviors

2019 Turkish Journal of Electrical Engineering and Computer Sciences  
Graph-based approaches have been widely employed to facilitate in analyzing network flow connectivity behaviors, which aim to understand the impacts and patterns of network events.  ...  In this paper, we propose network flow connectivity graphs (NFCGs) to capture network flow behavior for modeling social behaviors from network entities.  ...  Rich club connectivity is typically analyzed with the following procedure [13] : first sort nodes in the order of decreasing node degree rank value, then calculate the connectivity at degree k.  ...

Open source software and the economics of organization [chapter]

Giampaolo Garzarelli
2003 Routledge Foundations of the Market Economy  
Open source software development has organizational characteristics that are out of the ordinary (e.g., no hierarchy, selforganization, self-regulation, and no ownership structure).  ...  The claim is in fact that this organization is at least as good as a firm in sharing rich types of information in real time because (a) constituents have symmetry of absorptive capacity, and (b) software  ...  several licenses governing open source. Analyzing these in detail necessitates a study of its own.  ...
