Although science is becoming increasingly collaborative, there are remarkably few success stories of online collaborations between professional scientists that actually result in real discoveries. A notable exception is the Polymath Project, a group of mathematicians who collaborate online to solve open mathematics problems. We provide an in-depth descriptive history of Polymath, using data analysis and visualization to elucidate the principles that led to its success, and the difficulties that must be addressed before the project can be scaled up. We find that although a small percentage of users created most of the content, almost all users nevertheless contributed some content that was highly influential to the task at hand. We also find that leadership played an important role in the success of the project. Based on our analysis, we present a set of design suggestions for how future collaborative mathematics sites can encourage and foster newcomer participation. Author Keywords large-scale collaboration, online collaborative mathematics, online collaborative science, online communities

Traditional research on leadership in online communities has consistently focused on the small set of people occupying leadership roles. In this paper, we use a model of shared leadership, which posits that leadership behaviors come from members at all levels, not simply from people in high-level leadership positions. Although every member can exhibit some leadership behavior, different types of leadership behavior performed by different types of leaders may not be equally effective. This paper investigates how distinct types of leadership behaviors (transactional, aversive, directive and person-focused) and the legitimacy of the people who deliver them (people in formal leadership positions or not) influence the contributions that other participants make in the context of Wikipedia. After using propensity score matching to control for potential preexisting differences among those who were and were not targets of leadership behaviors, we found that 1) leadership behaviors performed by members at all levels significantly influenced other members ’ motivation; 2) transactional leadership and person-focused leadership were effective in motivating others to contribute more, whereas aversive leadership decreased other contributors ’ motivations; and 3) legitimate leaders were in general more influential than regular peer leaders. We discuss the theoretical and practical implication of our work. Author Keywords Shared leadership, online communities, Wikipedia, motivation

To lower the threshold to participation in crowdsourcing, we present twitch crowdsourcing: crowdsourcing via quick contributions that can be completed in one or two seconds. We introduce Twitch, a mobile phone application that asks users to make a micro-contribution each time they unlock their phone. Twitch takes advantage of the common habit of turning to the mobile phone in spare moments. Twitch crowdsourcing activities span goals such as authoring a census of local human activity, rating stock photos, and extracting structured data from Wikipedia pages. We report a field deployment of Twitch where 82 users made 11,240 crowdsourcing contributions as they used their phone in the course of everyday life. The median Twitch activity took just 1.6 seconds, incurring no statistically distinguishable costs to unlock speed or cognitive load compared to a standard slide-to-unlock interface.

The past twenty years have seen broad popularization of a relatively novel kind of human enterprise: open collaboration. Open collaboration projects are distributed, collaborative efforts made possible because of changes in information and communication technology that facilitate cooperative activities. The groundswell of open collaboration could be felt in the open source movement of the 90s but became unmistakable with the growth of projects like Wikipedia and, in particular, the maturation of research to help explain how and why such systems work, who participates, and when they might fail. By now thousands of scholars have written about open collaboration systems, many hundreds of thousands of people have participated in them, and millions of people use products of open collaboration every day. This special issue of American Behavioral Scientist assembles interdisciplinary scholarship that examines different aspects of open collaboration and the diverse systems that support it. The goal of this short introductory piece is to define open collaboration and contextualize a set of articles that span multiple disciplines and methods in a common vocabulary and history. We provide a definition of open collaboration and situate the phenomenon within an interrelated set of scholarly and ideological movements. We then examine the properties of open collaboration systems that have given rise to research and review major areas of scholarship, including the works in this issue, and close with a

Abstract: In this paper, we use evidence from a remixing community to evaluate two pieces of common wisdom about collaboration. First, we test the theory that jointly produced works tend to be of higher quality than individually authored products. Second, we test the theory that collaboration improves the quality of functional works like code, but that it works less well for artistic works like images and sounds. We use data from Scratch, a large online community where hundreds of thousands of young users share and remix millions of animations and inter-active games. Using peer-ratings as a measure of quality, we estimate a series of fitted regression models and find that collaborative Scratch projects tend to receive ratings that are lower than individually authored works. We also find that code-intensive collaborations are rated higher than media-intensive efforts. We conclude by discussing the limitations and implications of these findings.

ABSTRACT By lowering the costs of communication, the web promises to enable distributed collectives to act around shared issues. However, many collective action efforts never succeed: while the web's affordances make it easy to gather, these same decentralizing characteristics impede any focus towards action. In this paper, we study challenges to collective action efforts through the lens of online labor by engaging with Amazon Mechanical Turk workers. Through a year of ethnographic fieldwork, we sought to understand online workers' unique barriers to collective action. We then created Dynamo, a platform to support the Mechanical Turk community in forming publics around issues and then mobilizing. We found that collective action publics tread a precariously narrow path between the twin perils of stalling and friction, balancing with each step between losing momentum and flaring into acrimony. However, specially structured labor to maintain efforts' forward motion can help such publics take action.

This paper presents a qualitative study of attitudes towards participation and contribution in an online creative community. The setting of the work is an online community of practice focused on the use and development of a user-customizable music software package called Reaktor. Findings from the study highlight four emergent topics in the discourse related to user contributions to the community: contribution assessment, support for learning, perceptions of audience and tensions about commercialization. Our analysis of these topics frames discussion about the value and challenges of attending to amateur and professional users in online creative communities.

In online creative communities, members work together to produce music, movies, games, and other cultural products. Despite the proliferation of collaboration in these communities, we know little about how these teams form and what leads to their ultimate success. Building on theories of social identity and exchange, we present an exploratory study of an online songwriting community. We analyze four years of longitudinal behavioral data using a novel path-based regression model that accurately predicts and reveals key variables about collab formation. Combined with a large-scale survey of members, we find that communication, nuanced complementary interest and status, and a balanced effort from both parties contribute to successful collaborations. We also discuss several applications of these findings for socio-technical infrastructures that support online creative production.

We report a study of Wikipedia in which we use a mixed-methods approach to understand how participation in specialized workgroups called WikiProjects has changed over the life of the encyclopedia. While previous work has analyzed the work of WikiProjects in supporting the development of articles within particular subject domains, the collaborative role of WikiProjects that do not fit this conventional mold has not been empirically examined. We combine content analysis, interviews and analysis of edit logs to identify and characterize these alternative WikiProjects and the work they do. Our findings suggest that WikiProject participation reflects community concerns and shifts in the community’s conception of valued work over the past six years. We discuss implications for other open collaborations that need flexible, adaptable coordination mechanisms to support a range of content creation, curation and community maintenance tasks.
