Tracking and Unpacking Rumor Permutations to Understand Collective Sensemaking Online

Emma S. Spiro (PI), Kate Starbird (Co-PI)

Tracking and Unpacking Rumor Permutations to Understand Collective Sensemaking OnlineThis research addresses empirical and conceptual questions about online rumoring, asking: (1) How do online rumors permute, branch, and otherwise evolve over the course of their lifetime? (2) How can theories of rumor spread in offline settings be extended to online interaction, and what factors (technological and behavioral) influence these dynamics, perhaps making online settings distinct environments for information flow? The dynamics of information flow are particularly salient in the context of crisis response, where social media have become an integral part of both the formal and informal communication infrastructure. Improved understanding of online rumoring could inform communication and information-gathering strategies for crisis responders, journalists, and citizens affected by disasters, leading to innovative solutions for detecting, tracking, and responding to the spread of misinformation and malicious rumors. This project has the potential to fundamentally transform both methods and theories for studying collective behavior online during disasters. Techniques developed for tracking rumors as they evolve and spread over social media will aid other researchers in addressing similar problems in other contexts. Learn more

Understanding Online Audiences for Police on Social Media

Emma S. Spiro (PI)

Understanding Online Audiences for Police on Social MediaA number of high-profile incidents have highlighted tensions between citizens and police, bringing issues of police-citizen trust and community policing to the forefront of the public’s attention. Efforts to mediate this tension emphasize the importance of promoting interaction and developing social relationships between citizens and police. This strategy – a critical component of community policing – may be employed in a variety of settings, including social media. While the use of social media as a community policing tool has gained attention from precincts and law enforcement oversight bodies, the ways in which police are expected to use social media to meet these goals remains an open question. This study seeks to explore how police are currently using social media as a community policing tool. It focuses on Twitter – a functionally flexible social media space – and considers whether and how law enforcement agencies are co-negotiating norms of engagement within this space, as well as how the public responds to the behavior of police accounts.

Mass Convergence of Attention During Crisis Events

Emma S. Spiro (PI)

Detecting Misinformation Flows in Social Media Spaces During Crisis EventsWhen crises occur, including natural disasters, mass casualty events, and political/social protests, we observe drastic changes in social behavior. Local citizens, emergency responders and aid organizations flock to the physical location of the event. Global onlookers turn to communication and information exchange platforms to seek and disseminate event-related content. This social convergence behavior, long known to occur in offline settings in the wake of crisis events, is now mirrored – perhaps enhanced – in online settings. This project looks specifically at the mass convergence of public attention onto emergency responders during crisis events. Viewed through the framework of social network analysis, convergence of attention onto individual actors can be conceptualized in terms of network dynamics. This project employs a longitudinal study of social network structures in a prominent online social media platform to characterize instances of social convergence behavior and subsequent decay of social ties over time, across different actors types and different event types.

Social Interaction and Peer Influence in Activity-Based Online Communities

Emma Spiro (Co-PI), Zack Almquist (Co-PI)

Social Interaction and Peer Influence in Activity-Based Online CommunitiesIndividuals are influenced by their social networks. People adjust not only their opinions and attitudes, but also their behaviors based on both direct and indirect interaction with peers. Questions about social influence are particularly salient for activity-based behaviors; indeed much attention has been paid to promoting healthy habits through social interaction in online communities. A particularly interesting implication of peer influence in these settings is the potential for network-based interventions that utilize network processes to promote or contain certain behaviors or actions in a population; however, the first step toward designing such intervention strategies is to understand how, when, and to what extent social signals delivered via social interaction influence behavior. This project fills this gap by using digital traces of behaviors in online platforms to observe and understand how social networks and interactions are associated with behavior and behavior change.

Detecting Misinformation Flows in Social Media Spaces During Crisis Events

Kate Starbird (PI), Emma Spiro (Co-PI), Robert Mason (Co-PI)

Detecting Misinformation Flows in Social Media Spaces During Crisis EventsThis research seeks both to understand the patterns and mechanisms of the diffusion of misinformation on social media and to develop algorithms to automatically detect misinformation as events unfold. During natural disasters and other hazard events, individuals increasingly utilize social media to disseminate, search for and curate event-related information. Eyewitness accounts of event impacts can now be shared by those on the scene in a matter of seconds. There is great potential for this information to be used by affected communities and emergency responders to enhance situational awareness and improve decision-making, facilitating response activities and potentially saving lives. Yet several challenges remain; one is the generation and propagation of misinformation. Indeed, during recent disaster events, including Hurricane Sandy and the Boston Marathon bombings, the spread of misinformation via social media was noted as a significant problem; evidence suggests it spread both within and across social media sites as well as into the broader information space.

Taking a novel and transformative approach, this project aims to utilize the collective intelligence of the crowd – the crowdwork of some social media users who challenge and correct questionable information – to distinguish misinformation and aid in its detection. It will both characterize the dynamics of misinformation flow online during crisis events, and develop a machine learning strategy for automatically identifying misinformation by leveraging the collective intelligence of the crowd. The project focuses on identifying distinctive behavioral patterns of social media users in both spreading and challenging or correcting misinformation. It incorporates qualitative and quantitative methods, including manual and machine-based content analysis, to look comprehensively at the spread of misinformation. Learn more

Hazards, Emergency Response and Online Informal Communication

Emma S. Spiro (PI)

Hazards, Emergency Response and Online Informal CommunicationProject HEROIC is a collaborative, NSF funded effort with researchers at the University of Kentucky and the University of California, Irvine which strives to better understand the dynamics of informal online communication in response to extreme events.

The nearly continuous, informal exchange of information — including such mundane activities as gossip, rumor, and casual conversation — is a characteristic human behavior, found across societies and throughout recorded history. While often taken for granted, these natural patterns of information exchange become an important “soft infrastructure” for decentralized resource mobilization and response during emergencies and other extreme events. Indeed, despite being historically limited by the constraints of physical proximity, small numbers of available contacts, and the frailties of human memory, informal communication channels are often the primary means by which time-sensitive hazard information first reaches members of the public. This capacity of informal communication has been further transformed by the widespread adoption of mobile devices (such as “smart-phones”) and social media technologies (e.g., microblogging services such as Twitter), which allow individuals to reach much larger numbers of contacts over greater distances than was possible in previous eras.

Although the potential to exploit this capacity for emergency warnings, alerts, and response is increasingly recognized by practitioners, much remains to be learned about the dynamics of informal online communication in emergencies — and, in particular, about the ways in which existing streams of information are modified by the introduction of emergency information from both official and unofficial sources. Our research addresses this gap, employing a longitudinal, multi-hazard, multi-event study of online communication to model the dynamics of informal information exchange in and immediately following emergency situations.

Eigenfactor Project

Jevin D. West, Carl Bergstrom

The aim of the Eigenfactor Project is to develop methods, algorithms, and visualizations for mapping the structure of science. We use these maps to identify (1) disciplines and emerging areas of science, (2) key authors, papers and venues and (3) communication patterns such as differences in gender bias. We also use these maps to study scholarly publishing models and build recommendation engines and search interfaces for improving how scholars access and navigate the literature. Learn more

Open Access Project

Jevin D. West, Carl Bergstrom

The open access movement has made great strides. There has been a significant increase in Open Access journals over the last ten years and many large foundations now require OA. Unfortunately, during the same time, there has been a signficant increase in exploitative, predatory publishers, which charge authors to publish with little or no peer review, editorial services or authentic certification. We are developing a cost effectiveness tool that will create an open journal market of prices and influence scores where these kinds of journals can be objectively identified [2]. Learn more

Cross-platform analysis of the information operation targeting the White Helmets in Syria

Kate Starbird (PI)
Ph.D. Student Lead: Tom Wilson

While there is increasing awareness and research about online information operations—efforts by state and non-state actors to manipulate public opinion through methods such as the coordinated dissemination of disinformation, amplification of specific accounts or messages, and targeted messaging by agents who impersonate online political activists—there is still a lot we do not understand, including how these operations take place across social media platforms. In this research we are investigating cross-platform collaboration and content amplification that can work to propagate disinformation, specifically as part of an influence campaign targeting the White Helmets, a volunteer response organization that operates in Syria.

Through a mixed-method approach that uses ‘seed’ data from Twitter, we have examined the role of YouTube in the influence campaign against the White Helmets. Preliminary findings suggest that on Twitter the accounts working to discredit and undermine the White Helmets are far more active and prolific than those that support the group. Furthermore, this cluster of anti-WH accounts on Twitter uses YouTube as a resource—leveraging the specific affordances of the different platforms in complementary ways to achieve their objectives.

Using Facebook engagements to assess how information operations micro-target online audiences using “alternative” new media

Kate Starbird (PI)
Ph.D. Student Lead: Tom Wilson

There is a pressing need to understand how social media platforms are being leveraged to conduct information operations. In addition to being deployed to influence democratic processes, information operations are also utilized to complement kinetic warfare on a digital battlefield. In prior work we have developed a deep understanding of the Twitter-based information operations conducted in the context of the civil war in Syria. Extending upon this work, this project examines how Facebook is leveraged within information operations, and how a subsection of the “alternative” media ecosystem is integrated into those operations. We aim to understand the structure and dynamics of the media ecosystem that is utilized by information operations to manipulate public opinion, and more about the audiences that engage with related content from these domains. Our research will provide insight into how Facebook features into a persistent, multi-platform information operations campaign. Complementing previous research, it will provide insight into how a subsection of the alternative media ecosystem is leveraged by political entities to micro-target participants in specific online communities with strategic messaging and disinformation.

Helping Journalists Unravel the Trajectories of Online Disinformation

Ph.D. Student Lead: Melinda McClure Haughey

CiP researchers have been studying the online spread of rumors, misinformation, and disinformation for several years. We have developed and continue to expand and refine the infrastructure and research methods for collecting, curating, and analyzing social media data related to these phenomena. In this project, we explore strategies to extend our methods and to develop tools and techniques that allow other people—especially journalists and humanitarian responders—to analyze digital trace data themselves.

Unraveling Online Disinformation Trajectories: Applying and Translating a Mixed-Method Approach to Identify, Understand and Communicate Information Provenance

Kate Starbird (PI)

Unraveling Online Disinformation Trajectories: Applying and Translating a Mixed-Method Approach to Identify, Understand and Communicate Information ProvenanceThis project will improve our understanding of the spread of disinformation in online environments. It will contribute to the field of human-computer interaction in the areas of social computing, crisis informatics, and human centered data science. Conceptually, it explores relationships between technology, structure, and human action – applying the lens of structuration theory towards understanding how technological affordances shape online action, how online actions shape the underlying structure of the information space, and how those integrated structures shape information trajectories. Methodologically, it enables further development, articulation and evaluation of an iterative, mixed method approach for interpretative analysis of “big” social data. Finally, it aims to leverage these empirical, conceptual and methodological contributions towards the development of innovative solutions for tracking disinformation trajectories.

The online spread of disinformation is a societal problem at the intersection of online systems and human behavior. This research program aims to enhance our understanding of how and why disinformation spreads and to develop tools and methods that people, including humanitarian responders and everyday analysts, can use to detect, understand, and communicate its spread. The research has three specific, interrelated objectives: (1) to better understand the generation, evolution, and propagation of disinformation; (2) to extend, support, and articulate an evolving methodological approach for analyzing “big” social media data for use in identifying and communicating “information provenance” related to disinformation flows; (3) to adapt and transfer the tools and methods of this approach for use by diverse users for identification of disinformation and communication of its origins and trajectories. More broadly, it will contribute to the advancement of science through enhanced understandings and conceptualization of the relationships between technological affordances, social network structure, human behavior, and intentional strategies of deception. The program includes an education plan that supports PhD student training and recruits diverse undergraduate students into research through multiple mechanisms, including for-credit research groups and an academic bridge program.

Community Labs in Public Libraries

Rolf Hapel, Chris Coward, Chris Jowaisas, Jason Young

Given their historic role of curating information, libraries have the potential to be key players in combating misinformation, political bias, and other threats to democracy. This research project seeks to support public libraries in their efforts to address misinformation by developing library-based community labs: spaces where patrons can collectively explore pressing social issues. Community labs have become popular across many European countries, where they are used to instigate democratic debate, provide discussion spaces and programming, alleviate community tensions, and promote citizenship and mutual understanding. This project aims to adapt a community lab model for use by public libraries in Washington. Learn more
