Characterizing the structural diversity of complex networks across domains

The structure of complex networks has been of interest in many scientific and engineering disciplines over the decades. A number of studies in the field have been focused on finding the common properties among different kinds of networks such as heavy-tail degree distribution, small-worldness and modular structure and they have tried to establish a theory of structural universality in complex networks. However, there is no comprehensive study of network structure across a diverse set of domains in order to explain the structural diversity we observe in the real-world networks. In this paper, we study 986 real-world networks of diverse domains ranging from ecological food webs to online social networks along with 575 networks generated from four popular network models. Our study utilizes a number of machine learning techniques such as random forest and confusion matrix in order to show the relationships among network domains in terms of network structure. Our results indicate that there are some partitions of network categories in which networks are hard to distinguish based purely on network structure. We have found that these partitions of network categories tend to have similar underlying functions, constraints and/or generative mechanisms of networks even though networks in the same partition have different origins, e.g., biological processes, results of engineering by human being, etc. This suggests that the origin of a network, whether it's biological, technological or social, may not necessarily be a decisive factor of the formation of similar network structure. Our findings shed light on the possible direction along which we could uncover the hidden principles for the structural diversity of complex networks.

Mapping the Conference

Our goal with this initial experiment was not to set up a fully participatory community network mapping process, as this would have required a much longer time frame and many more resources. We focused on the following questions:

What would an initial map representing both the diversity and common ground in this emerging field look like?
How to create it with contributions from the participants?
How to use the map to give conference participants some sense of what their emerging field literally looks like?
Can we design practical maps-based conference activities that help conference participants contribute to further field building?
To answer these questions, renowned group facilitator Nancy White,  INGENAES Associate Director Andrea Bohn, and I came up with a participatory process involving producing the actual map, facilitated sensemaking sessions, lots of commitment, as well as the essential bit of fun! We wanted to make the mapping and facilitation processes “dance together”, as it were, with the maps helping to set the agenda for engaged conversations held in the facilitated sessions, while also capturing conference results and “seeds for action” to be followed up on after the conference.

Complex Contagions: A Decade in Review

Since the publication of 'Complex Contagions and the Weakness of Long Ties' in 2007, complex contagions have been studied across an enormous variety of social domains. In reviewing this decade of research, we discuss recent advancements in applied studies of complex contagions, particularly in the domains of health, innovation diffusion, social media, and politics. We also discuss how these empirical studies have spurred complementary advancements in the theoretical modeling of contagions, which concern the effects of network topology on diffusion, as well as the effects of individual-level attributes and thresholds. In synthesizing these developments, we suggest three main directions for future research. The first concerns the study of how multiple contagions interact within the same network and across networks, in what may be called an ecology of contagions. The second concerns the study of how the structure of thresholds and their behavioral consequences can vary by individual and social context. The third area concerns the roles of diversity and homophily in the dynamics of complex contagion, including both diversity of demographic profiles among local peers, and the broader notion of structural diversity within a network. Throughout this discussion, we make an effort to highlight the theoretical and empirical opportunities that lie ahead.

Temporal Network Epidemiology

This book covers recent developments in epidemic process models and related data on temporally varying networks. It is widely recognized that contact networks are indispensable for describing, understanding, and intervening to stop the spread of infectious diseases in human and animal populations; “network epidemiology” is an umbrella term to describe this research field.

More recently, contact networks have been recognized as being highly dynamic. This observation, also supported by an increasing amount of new data, has led to research on temporal networks, a rapidly growing area. Changes in network structure are often informed by epidemic (or other) dynamics, in which case they are referred to as adaptive networks.

This volume gathers contributions by prominent authors working in temporal and adaptive network epidemiology, a field essential to understanding infectious diseases in real society.

"Foundations as Network Strategists, Weavers, and Managers: Learning Fr" by Clare Nolan, Brian Souza et al.

"Foundations as Network Strategists, Weavers, and Managers: Learning Fr" by Clare Nolan, Brian Souza et al. | networks and network weaving | Scoop.it

Excellent article - well worth the read!

 

"This article shares insights from a five-year evaluation of the Oral Health 2020 network, an effort by the DentaQuest Foundation to align and strengthen efforts in service of a national movement to improve oral health. The evaluation helped to place the foundation’s journey in the context of a broader field seeking new approaches to achieve deep and sustainable social change.
The foundation’s approach was informed by several ideas that have gained momentum in the social sector, including collective impact, networks, systems change, and equity – all of which challenged the foundation to take a nontraditional approach that combined the roles of network hub, weaver, and backbone organization.
Six years in, the network has achieved notable successes, but along the way the foundation and its partners learned numerous lessons about what it takes to build and sustain a national network. This article shares those lessons, and also considers changes in federal policy and their implications.

Patterns of Commoning: Commoning in Times of Disaster - The Humanitarian OpenStreetMap Team | P2P Foundation

Patterns of Commoning: Commoning in Times of Disaster - The Humanitarian OpenStreetMap Team | P2P Foundation | networks and network weaving | Scoop.it
Just a few hours after the 7.0 magnitude earthquake hit Haiti in January 2010, a group of collaborators from the OpenStreetMap community began collecting all sorts of topographical data about the country – roads, towns, hospitals, government buildings. Within forty-eight hours high-resolution satellite imagery taken after the earthquake became available, and within a month over 600 people had added information to OpenStreetMap of Haiti.

This online map quickly became the default basemap for a wide variety of responders – search and rescue teams, the United Nations, the World Bank, and humanitarian mapping organizations such as MapAction. It turned out to be the first step in the formation of the Humanitarian OpenStreetMap Team, or HOT, which has gone on to organize dozens of similar humanitarian mapping projects over the past five years.

The project amounts to a “mapping commons” whose freely available geographic data is invaluable to humanitarian responders to natural disasters and crises. The maps are also widely used by communities to help them formulate and pursue their own development goals.

Evidence of complex contagion of information in social media: An experiment using Twitter bots

It has recently become possible to study the dynamics of information diffusion in techno-social systems at scale, due to the emergence of online platforms, such as Twitter, with millions of users. One question that systematically recurs is whether information spreads according to simple or complex dynamics: does each exposure to a piece of information have an independent probability of a user adopting it (simple contagion), or does this probability depend instead on the number of sources of exposure, increasing above some threshold (complex contagion)? Most studies to date are observational and, therefore, unable to disentangle the effects of confounding factors such as social reinforcement, homophily, limited attention, or network community structure. Here we describe a novel controlled experiment that we performed on Twitter using ‘social bots’ deployed to carry out coordinated attempts at spreading information. We propose two Bayesian statistical models describing simple and complex contagion dynamics, and test the competing hypotheses. We provide experimental evidence that the complex contagion model describes the observed information diffusion behavior more accurately than simple contagion. Future applications of our results include more effective defenses against malicious propaganda campaigns on social media, improved marketing and advertisement strategies, and design of effective network intervention techniques.

In 2009, the Human Connectome Project (HCP) was launched to  to build a “network map” (connectome) for the healthy human brain. The purpose of the connectome is to decipher the amazingly complex wiring diagram to reveal what makes us uniquely human and what makes every person different from all others. Dr. Olaf Sporns from Indiana University at Bloomington, author of Networks of the Brain (February 2011) has been leading the work of creating a complete connection (network) map of the brain.  According to Sporns, “Understanding the human brain is one of the great scientific challenges of the 21st century.”
