Essays on collective intelligence

Curated on Posted on by Stefaan Verhulst

Thesis by Yiftach Nagar: “This dissertation consists of three essays that advance our understanding of collective-intelligence: how it works, how it can be used, and how it can be augmented. I combine theoretical and empirical work, spanning qualitative inquiry, lab experiments, and design, exploring how novel ways of organizing, enabled by advancements in information technology, can help us work better, innovate, and solve complex problems.

The first essay offers a collective sensemaking model to explain structurational processes in online communities. I draw upon Weick’s model of sensemaking as committed-interpretation, which I ground in a qualitative inquiry into Wikipedia’s policy discussion pages, in attempt to explain how structuration emerges as interpretations are negotiated, and then committed through conversation. I argue that the wiki environment provides conditions that help commitments form, strengthen and diffuse, and that this, in turn, helps explain trends of stabilization observed in previous research.

In the second essay, we characterize a class of semi-structured prediction problems, where patterns are difficult to discern, data are difficult to quantify, and changes occur unexpectedly. Making correct predictions under these conditions can be extremely difficult, and is often associated with high stakes. We argue that in these settings, combining predictions from humans and models can outperform predictions made by groups of people, or computers. In laboratory experiments, we combined human and machine predictions, and find the combined predictions more accurate and more robust than predictions made by groups of only people or only machines.

The third essay addresses a critical bottleneck in open-innovation systems: reviewing and selecting the best submissions, in settings where submissions are complex intellectual artifacts whose evaluation require expertise. To aid expert reviewers, we offer a computational approach we developed and tested using data from the Climate CoLab – a large citizen science platform. Our models approximate expert decisions about the submissions with high accuracy, and their use can save review labor, and accelerate the review process….(More)”

Thomas Kohnstamm on Alberto Cairo, Power BI & the rise of data journalism for Microsoft Stories: “From the election of Pope Francis to the passing of Nelson Mandela to Miley Cyrus’ MTV #twerk heard ’round the world, 2013 was full of big headlines and viral hits. Yet The New York Times’ top story of the year was the humble result of a vocabulary survey of 350,000 randomly selected Americans conducted by a then-intern at the paper.

Instead of presenting these findings in a written article, “How Y’all, Youse and You Guys Talk” achieved breakout success as an interactive data visualization. It asked readers 25 questions such as “How would you address a group of two or more people?” or “How do you pronounce ‘aunt’?” and then heat-mapped their responses to the most similar regional dialect in the U.S. The interactivity and colorful visuals transmuted survey data into a fun, insightful tour through the contours of contemporary AmericanEnglish.

Visualization no longer just complements a written story. It is the story. In our increasingly data-driven world, visualization is becoming an essential tool for journalists from national papers to blogs with a staff of one.

I recently spent two days discussing the state of data journalism with Alberto Cairo, the Knight Chair of Visual Journalism at the School of Communication at the University of Miami. While he stressed the importance of data visualization for efficient communication and audience engagement, Cairo argued that “Above all else, visualizations — when done right — are a vehicle of clarification and truth.”…(More)”

Supporting Collaborative Political Decision Making: An Interactive Policy Process Visualization System

Curated on Posted on by Stefaan Verhulst

Paper by Tobias Ruppert et al: “The process of political decision making is often complex and tedious. The policy process consists of multiple steps, most of them are highly iterative. In addition, different stakeholder groups are involved in political decision making and contribute to the process. A series of textual documents accompanies the process. Examples are official documents, discussions, scientific reports, external reviews, newspaper articles, or economic white papers. Experts from the political domain report that this plethora of textual documents often exceeds their ability to keep track of the entire policy process. We present PolicyLine, a visualization system that supports different stakeholder groups in overview-and-detail tasks for large sets of textual documents in the political decision making process. In a longitudinal design study conducted together with domain experts in political decision making, we identified missing analytical functionality on the basis of a problem and domain characterization. In an iterative design phase, we created PolicyLine in close collaboration with the domain experts. Finally, we present the results of three evaluation rounds, and reflect on our collaborative visualization system….(More)”

‘Good Nudge Lullaby’: Choice Architecture and Default Bias Reinforcement

Curated on Posted on by Stefaan Verhulst

Thomas De Haan and Jona Linde in The Economic Journal: “Because people disproportionally follow defaults, both libertarian paternalists and marketers try to present options they want to promote as the default. However, setting certain defaults and thereby influencing current decisions, may also affect choices in later, similar decisions. In this paper we explore experimentally whether the default bias can be reinforced by providing good defaults. We show that people who faced better defaults in the past are more likely to follow defaults than people who faced random defaults, hurting their later performance. This malleability of the default bias explains certain marketing practices and serves as an insight for libertarian paternalists….(More)”

Open parliament policy applied to the Brazilian Chamber of Deputies

Curated on Posted on by Stefaan Verhulst

Paper by Cristiano Faria & Malena Rehbein  in The Journal of Legislative Studies:”…analyse the implementation of an open parliament policy that is taking place at the Chamber of Deputies, in accordance with the guidelines of the Open Government Partnership international programme (OGP), regarding the action plan of the Opening Parliament Work Group in particular, one of the subgroups of OGP. The authors will evaluate two blocks of initiatives for open parliaments executed by the Chamber in the last few years, that is, digital participation in the legislative process and Transparency 2.0, in order to observe their impasses and results obtained until now. In the first part the authors will study the e-Democracy portal and in the second part the authors will focus on open data, collaborative activities to use those data (hackathons) and the creation of the Hacker Lab, a permanent space dedicated to open parliament practices. The analysis considers the initiatives that the authors evaluated as part of the transformative and arena profiles of the Brazilian Parliament, according to Polsby’s classification, with exclusive characteristics….

Crowdsourcing and cellphone data could help guide urban revitalization

Curated on Posted on by Stefaan Verhulst

Science Magazine: “For years, researchers at the MIT Media Lab have been developing a database of images captured at regular distances around several major cities. The images are scored according to different visual characteristics — how safe the depicted areas look, how affluent, how lively, and the like….Adjusted for factors such as population density and distance from city centers, the correlation between perceived safety and visitation rates was strong, but it was particularly strong for women and people over 50. The correlation was negative for people under 30, which means that males in their 20s were actually more likely to visit neighborhoods generally perceived to be unsafe than to visit neighborhoods perceived to be safe.

In the same paper, the researchers also identified several visual features that are highly correlated with judgments that a particular area is safe or unsafe. Consequently, the work could help guide city planners in decisions about how to revitalize declining neighborhoods.,,,

Jacobs’ theory, Hidalgo says, is that neighborhoods in which residents can continuously keep track of street activity tend to be safer; a corollary is that buildings with street-facing windows tend to create a sense of safety, since they imply the possibility of surveillance. Newman’s theory is an elaboration on Jacobs’, suggesting that architectural features that demarcate public and private spaces, such as flights of stairs leading up to apartment entryways or archways separating plazas from the surrounding streets, foster the sense that crossing a threshold will bring on closer scrutiny….(More)”

The openness buzz in the knowledge economy: Towards taxonomy

Curated on Posted on by Stefaan Verhulst

Paper by Anne Lundgren in “Environment and Planning C: Government and Policy”: “In the networked information and knowledge-based economy and society, the notions of ‘open’ and ‘openness’ are used in a variety of contexts; open source, open access, open economy, open government, open innovation – just to name a few. This paper aims at discussing openness and developing a taxonomy that may be used to analyse the concept of openness. Are there different qualities of openness? How are these qualities interrelated? What analytical tools may be used to understand openness? In this paper four qualities of openness recurrent in literature and debate are explored: accessibility, transparency, participation and sharing. To further analyse openness new institutional theory as interpreted by Williamson (2000) is used, encompassing four different institutional levels; cultural embeddedness, institutional environment, governance structure and resource allocations. At what institutional levels is openness supported and/or constrained? Accessibility as a quality of openness seems to have a particularly strong relation to the other qualities of openness, whereas the notions of sharing and collaborative economics seem to be the most complex and contested quality of openness in the knowledge-based economy. This research contributes to academia, policy and governance, as handling of challenges with regard to openness vs. closure in different contexts, territorial, institutional and/or organizational, demand not only a better understanding of the concept, but also tools for analysis….(More)”

Reframing Data Transparency

Curated on Posted on by Stefaan Verhulst

“Recently, the Centre for Information Policy Leadership (“CIPL”) at Hunton & Williams LLP, a privacy and information policy think tank based in Brussels, London and Washington, D.C., and Telefónica, one of the largest telecommunications company in the world, issued a joint white paper on Reframing Data Transparency (the “white paper”). The white paper was the outcome of a June 2016 roundtable held by the two organizations in London, in which senior business leaders, Data Privacy Officers, lawyers and academics discussed the importance of user-centric transparency to the data driven economy….The issues explored during the roundtable and in the white paper include the following:

  • The transparency deficit in the digital age. There is a growing gap between traditional, legal privacy notices and user-centric transparency that is capable of delivering understandable and actionable information concerning an organization’s data use policies and practices, including why it processes data, what the benefits are to individuals and society, how it protects the data and how users can manage and control the use of their data.
  • The impact of the transparency deficit. The transparency deficit undermines customer trust and customers’ ability to participate more effectively in the digital economy.
  • Challenges of delivering user-centric transparency. In a connected world where there may be no direct relationship between companies and their end users, both transparency and consent as a basis for processing are particularly challenging.
  • Transparency as a multistakeholder challenge. Transparency is not solely a legal issue, but a multistakeholder challenge, which requires engagement of regulators, companies, individuals, behavioral economists, social scientists, psychologists and user experience specialists.
  • The role of data protection authorities (“DPAs”). DPAs play a key role in promoting and incentivizing effective data transparency approaches and tools.
  • The role of companies. Data transparency is a critical business issue because transparency drives digital trust as well as business opportunities. Organizations must innovate on how to deliver user-centric transparency. Data driven companies must research and develop new approaches to transparency that explain the value exchange between customers and companies and the companies’ data practices, and create tools that enable their customers to exercise effective engagement and control.
  • The importance of empowering individuals. It is crucial to support and enhance individuals’ digital literacy, which includes an understanding of the uses of personal data and the benefits of data processing, as well as knowledge of relevant privacy rights and the data management tools that are available to them. Government bodies, regulators and industry should be involved in educating the public regarding digital literacy. Such education should take place in schools and universities, and through consumer education campaigns. Transparency is the foundation and sine qua non of individual empowerment.
  • The role of behavioral economists, social scientists, psychologists and user experience specialists. Experts from these disciplines will be crucial in developing user-centric transparency and controls….(More)”.

Innovando para una mejor gestión: La contribución de los laboratorios de innovación pública

Curated on Posted on by Stefaan Verhulst

Paper by Acevedo, Sebastián; and Dassen, Nicolás for IDB: “Los cambios tecnológicos, económicos y sociales de los últimos años exigen gobiernos capaces de adaptarse a nuevos desafíos y a las crecientes demandas de la ciudadanía. En muchos países y en distintos niveles de gobierno, esto ha llevado a la creación de laboratorios de innovación, unidades cuyo objetivo es promover de diversos modos la innovación en el sector público. En este trabajo se analizan los roles y desafíos de los laboratorios latinoamericanos, contrastándolos con buenas prácticas y características que la literatura ha asociado a mayores niveles de innovación en el sector público y en otras organizaciones.

A partir de una encuesta a directores de laboratorios y dos estudios de casos, se describe el panorama de los laboratorios latinoamericanos y se discuten sus desafíos para: i) trabajar sobre temas centrales de la gestión, ii) conseguir la adopción de innovaciones y el escalamiento de las mismas y iii) asegurar la sostenibilidad de estas.

En particular, hay cuatro factores clave para su desempeño en esos aspectos: dos factores político-institucionales –el apoyo del liderazgo y las redes de política– y dos factores metodológicos –la adecuación técnica de las innovaciones y la construcción de un significado compartido sobre ellas–.

Además, se identifican dos diferencias principales entre la mayoría de los laboratorios relevados aquí y la experiencia de otras regiones, descripta por la literatura existente: un foco más intenso en temas de gobierno abierto y menos actividades para el testeo controlado de innovaciones, como experimentos aleatorios y evaluaciones de impacto. Finalmente, se presentan conclusiones y recomendaciones para la consolidación de los laboratorios como canales efectivos para gestionar innovaciones, manejando los riesgos inherentes, y modernizar la gestión… (More Español)

The well-informed city: A decentralized, bottom-up model for a smart city service using information and self-organization

Curated on Posted on by Stefaan Verhulst

Paper by Eyal Feder-Levy, Efrat Blumenfeld-Liebertal, and Juval Portugali for the Smart Cities Conference (ISC2), 2016 IEEE International: “Smart Cities, a concept widely growing in popularity, describes cities that use digital technology, data analysis and connectivity to create value. The basic abstraction of a Smart City service includes collecting data about an urban issue, transmitting it to a central decision making process and “improving” the city with the insights generated. This model has spurred much critique, claiming Smart Cities are undemocratic, discriminatory and cannot significantly improve citizen’s quality of life. But what if the citizens were active in the process? It was Jane Jacobs who said “Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.” In this paper we lay a conceptual groundwork to envision “The Well-Informed City” — a decentralized, self-organizing Smart City service, where the value is created by everybody. The agents, who are the citizens of the city, are the ones who use the data to create value. We base the model on the cities’ feature of Self-Organization as described in the domain of Complexity Theory of Cities. We demonstrate its theoretical possibility, describe a short case study and finish with suggestions for future empirical research. This work is highly significant due to the ubiquitous nature of contemporary mobile based information services and growing open data sets….(More)”
