In this paper we investigate the role of champions in processes of mass collaboration in software product development. The case is Get Satisfaction, a company and social media platform for engaging end users and customers in product development activities. We employ a mixed methods approach, combining social network analysis (SNA) and interaction analysis (IA). We found that when scaling up, a ...

[Background]Discovering key nodes plays a significant role in Social Network Analysis(SNA). Effective and accurate mining of key nodes promotes more successful applications in fields like advertisement and recommendation. [Methods] With focus on the temporal and categorical property of users’ actions when did they re-tweet or reply a message, as well as their social intimacy measured by structu...

How can individuals and communities protect their privacy against social network analysis tools? How do criminals or terrorists organizations evade detection by such tools? Under which conditions can these tools be made strategy proof? These fundamental questions have attracted little attention in the literature to date, as most social network analysis tools are built around the assumption that...

In this paper, we set out to explore some of the many ways in which Social Network Analysis (SNA) can be applied to the field of security. In particular, we investigate what information someone (e.g., an attacker) could infer if they were able to gather data on a person’s friend-groups or device communications (e.g., email interactions) and whether this could be used to predict the “hierarchica...

With the growing expansion of data size, in-depth study on the social network clustering algorithm gets prominence. A wide range of researches, from the spectral clustering based on modularity, the hierarchical overlapping clustering algorithm to clustering algorithm based on local information, are mainly based on local neighbor information. The current network node cluster typically has a lowe...

Background Global health partnerships have grown rapidly in number and scope, yet there has been less emphasis on their evaluation. Gavi, the Vaccine Alliance, is one such public-private partnership; in Gavi-eligible countries partnerships are dynamic networks of immunization actors who work together to support all stages and aspects of Gavi support. This paper describes a conceptual framework ...

Processual models of the early state envisioned hierarchical societies with stable social and political structures. More recent research, however, has questioned this vision. Here, authors explore Middle Horizon (AD 700–1000) Wari iconography to provide an example organisation from Central Andes. Social network analysis (SNA) human figures (‘agents’) depicted in art identifies links between ind...

In our note, we tried to realise a comprehensive document dedicated Social Network Analysis, in which focused on its origin, application and adoption analysing the diffusion of innovation, with particular attention paid agriculture sector, because believe that farmers can easily exchange knowledge each other boost innovation terms agricultural techniques. Most scientific researches reported not...

Abstract The concept of a “social network” has become popular term thanks to online tools such as Facebook or Twitter, allowing us connect with everyone. Specific archaeology, social network analysis (SNA) is well established method, but its theoretical application in maritime archaeology an incipient initiative. This paper presents the use SNA potential instrument reinterpret underwater sites ...
