Designing with crowds
… This dissertation explores the use of non-expert crowds to generate helpful, affordable, and timely feedback for visual design. The key innovation is the concept of generating structured feedback from non-experts. Based on a formative study, I identified several types of perception-oriented …

Data-Driven Modeling of Pedestrian Crowds
… work is still focused on artificial setups for crowds moving through corridors and crowds passing bottlenecks. Even though these controlled experiments are important to understand crowd dynamics, there is a knowledge gap between these experiments and the understanding of the dynamics leading to …

Mining Intelligence of Crowds for Knowledge Inference
Finally, we explore the possibilities of using knowledge repositories for expressing image information in the form of knowledge concepts. We build an affinity matrix for over 22 000 concepts and 135 000 images. Distributed infrastructure for handling terabytes of data is laid down and initial …

Enhancing Crowds to Support Truly Anonymous FTP Transactions
… most daunting challenges that we presently face. Crowds is the implementation of an approach to provide privacy to web transactions. The system's strategy is to seek concealment through numbers. A crowd consists of a collection of users that intend to participate in web exchanges; each user being …

Extracting the Wisdom of Crowds From Crowdsourcing Platforms
Enabled by the wave of online crowdsourcing activities, extracting the Wisdom of Crowds (WoC) has become an emerging research area, one that is used to aggregate judgments, opinions, or predictions from a large group of individuals for improved decision making. However, existing literature mostly …

Scaling Up Fact-Checking Using the Wisdom of Crowds
… average ratings of small, politically balanced crowds of laypeople (i) correlate with the average fact-checker ratings as well as the fact-checkers’ ratings correlate with each other and (ii) predict whether the majority of fact-checkers rated a headline as “true” with high accuracy. …

Identify experts through Revealed Confidence : application to Wisdom of Crowds
… (RC) algorithm that improves Wisdom of Crowds (WoC) by identifying experts from the crowds. We highlight the important distinction between first- and second-order uncertainty, which also serves as an explanation for rational overconfidence. Under our proposed belief updating mechanism, …

Leveraging AI to Combat Misinformation by Empowering Crowds and Evaluating Detectors
… professionals, non-expert ordinary users (a.k.a. crowds) can act as eyes-on-the-ground who proactively question and counter misinformation, showing promise in overcoming the limitations of solely relying on professionals. However, little is known about how these crowds organically combat …

Structuralist and interactionist perspectives of collective behavior and control of crowds.
… efficiently and effectively explain the crowds and the crowd control. Finally, the other factors in crowd control will be explored, and recommendations concerning the handling of crowds in a more peaceful manner will be made.

On the strategic transmission of information to imperfect agents and crowds
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-19 without embargo terms

High-level control of agent-based crowds by means of general constraints
The use of computer-generated crowds in visual effects has grown tremendously since the warring armies of virtual ores and elves were seen in The Lord of the Rings. These crowds are generated by agent-based simulations, where each agent has the ability to reason and act for itself. This autonomy is …

Essays on Mechanisms Underlying Belief Updating with Applications in Wisdom of Crowds
… leverage belief-updating to improve Wisdom of Crowds. In Chapter One, I propose a new Revealed Expertise (RE) algorithm that uses the “RE measure”, which is a scaled amount of belief updating given numerical advice (i.e., the group mean), as a proxy for prior variance to better reflect the …

Innovate with Crowds. Co-Creation and Idea Evaluation in Internal and External Crowdsourcing.
Crowdsourcing seems to be a promising approach for organizations to overcome challenges widely discussed in innovation and organizational research. However, the extent to which an organization can leverage the benefits from crowdsourcing is contingent on which type of crowd is addressed and how …

Solving Mysteries with Crowds: Supporting Crowdsourced Sensemaking with a Modularized Pipeline and Context Slices
… of expert analysts. Machine learning and crowdsourcing present new opportunities for large-scale sensemaking, but it remains a challenge to model the overall process so that many distributed agents can contribute to suitable components asynchronously and meaningfully. In this work, I …

CrowdConcept : assessing the crowd's creative capacity
Crowdsourcing creative work - the process of outsourcing a creative task to a large online community or crowd - has grown in popularity over the last decade and is now considered a serious design strategy. However, there has been little research examining how the composition of the crowd and the …

Dynamic image crowd representations for improved anomaly detection using generative adversarial networks
… and hence planning for, and managing crowds are integral parts of city and event planning. Effective analysis of crowd behaviour and anomaly detection has the potential for more efficient management and is a building block for smart environments. Closed-Circuit Televisions (CCTVs) …

Crowd Compositions for Bias Detection and Mitigation in Predicting Recidivism
… approach to predicting recidivism by leveraging crowdsourcing, contrasting traditional judicial discretion and algorithmic models. Instead of relying on judges or algorithms, participants predicted the likelihood of re-offending using the COMPAS dataset, which includes demographic and criminal …

Crowd-powered systems
… enable applications and experiences that neither crowds nor computation could support alone. Unfortunately, crowd work is error-prone and slow, making it difficult to incorporate crowds as first-order building blocks in software systems. I introduce computational techniques that decompose complex …

A People's War: The Transformation of German Politics, 1913-1918
… patriotic displays. In depicting the nationalist crowds, the German press began to recast political legitimacy in favor of the ""masses"" as newspapers reported crowds engaging in loud demonstrations in front of the kaiser's palace and forcing a reluctant monarch to repeatedly appear before the …

The (Non)normative Administration of Justice by the Crowd: An Adaptation and Application of Hirschman's Exit, Voice and Loyalty Framework
… explores the motivations and responses that crowds undertake in response to perceived injustices using a sequential exploratory research design. The dissertation uses multicase research to investigate the injustices against which crowds (broadly defined) are fighting and provides nuances into …
