Crowdsourcing has recently gained a lot of attention as a tool for conducting different kinds of relevance evaluations. At a very high level, crowdsourcing describes outsourcing of tasks to a large group of people instead of assigning such tasks to an in-house employee. This crowdsourcing approach makes possible to conduct information retrieval experiments extremely fast, with good results at a low cost.  相似文献

The paradox of openness describes the fundamental tension between knowledge sharing and knowledge protection in open innovation. While sharing is vital for value creation, protecting is critical for value appropriation. Prior research has examined this paradox of openness from the perspective of the seeking firm, focusing on the firm-level challenges of inbound open innovation. In this article, we complement that research by illuminating the tensions between sharing and protecting in individual-level outbound open innovation, where we argue that the paradox of openness is most prevalent, yet much less well understood. Drawing on the experience of individual participants, or solvers, in intermediated crowdsourcing contests, we analyze textual data from 2,149 answers to five open-ended narrative questions embedded in a large-scale solver survey, as well as 43 in-depth interviews of solvers. Our findings indicate that individual solvers face fundamental sharing-protecting tensions that carry considerable economic and psychological costs. We also document how solvers attempt to navigate the paradox of openness by employing three formal and four informal value appropriation practices. They build elaborate configurations of these practices, which they tailor to the idiosyncrasies of each contest. They also dynamically adjust these configurations over time, as the contest and the interaction with the seeker unfold. We end by outlining how these findings contribute to a more multifaceted conceptualization and a richer understanding of the paradox of openness.  相似文献

ABSTRACT

Inclusion of open resources that employ a peer-generated approach is changing who learns what, from whom, and via what means. With these changes, there is a shift in responsibilities from the course designer to motivated and self-directed learner-participants. While much research on e-learning has addressed challenges of creating and sustaining participatory environments, the development of massive open online courses calls for new approaches that go beyond the existing research on participatory environments in institutionally defined classes. We decenter institutionally defined classes and broaden the discussion to the literature on the creation of open virtual communities and the operation of open online crowds. We draw on literatures on online organizing, learning science, and emerging educational practice to discuss how collaboration and peer production shape learning and enable “crowdsourcing the curriculum.”  相似文献

What is the impact of platform design on crowdsourcing contributions? The proliferation of platforms with distributed content production, such as Wikipedia, Zooniverse, and others, has led to scholarly interest in understanding why individuals contribute to them. One stream of research has investigated contributor motivations, while another growing stream, scattered across several disciplines, has explored the effect of platform design on contributions. One important design element is the extent to which incomplete, or partial, contributions are possible - a concept we refer to in this paper as “tolerance to incompleteness.” We explore the relationship between this design element and crowds’ willingness to contribute in the context of Zooniverse, the world’s largest citizen science platform. Our quasi-experimental empirical approach exploits a format change that decreased tolerance to incompleteness in one Zooniverse project. The results of a difference-in-differences estimation show that after the format change, editors contributed fewer total edits, but more complete edits than predicted in the absence of a change. Users also spent less time contributing to the project post-change. Moreover, we find a trade-off between the quantity and quality of complete edits, with the quality of complete edits lower post-change. Our findings have implications for the design of a growing number of crowdsourcing platforms that involve simple, independent, and well-structured tasks.  相似文献

A growing amount of scientific research is done in an open collaborative fashion, in projects sometimes referred to as “crowd science”, “citizen science”, or “networked science”. This paper seeks to gain a more systematic understanding of crowd science and to provide scholars with a conceptual framework and an agenda for future research. First, we briefly present three case examples that span different fields of science and illustrate the heterogeneity concerning what crowd science projects do and how they are organized. Second, we identify two fundamental elements that characterize crowd science projects – open participation and open sharing of intermediate inputs – and distinguish crowd science from other knowledge production regimes such as innovation contests or traditional “Mertonian” science. Third, we explore potential knowledge-related and motivational benefits that crowd science offers over alternative organizational modes, and potential challenges it is likely to face. Drawing on prior research on the organization of problem solving, we also consider for what kinds of tasks particular benefits or challenges are likely to be most pronounced. We conclude by outlining an agenda for future research and by discussing implications for funding agencies and policy makers.  相似文献

In order to evaluate the effectiveness of Information Retrieval (IR) systems it is key to collect relevance judgments from human assessors. Crowdsourcing has successfully been used as a method to scale-up the collection of manual relevance judgments, and previous research has investigated the impact of different judgment task design elements (e.g., highlighting query keywords in the document) on judgment quality and efficiency. In this work we investigate the positive and negative impacts of presenting crowd human assessors with more than just the topic and the document to be judged. We deploy different variants of crowdsourced relevance judgment tasks following a between-subjects design in which we present different types of metadata to the human assessor. Specifically, we investigate the effect of human metadata (e.g., what other human assessors think of the current document, as in which relevance level has already been selected by the majority crowd workers), machine metadata (e.g., how IR systems scored this document such as its average position in ranked lists, statistics about the document such as term frequencies). We look at the impact of metadata on judgment quality (i.e., the level of agreement with trained assessors) and cost (i.e., the time it takes for workers to complete the judgments) as well as at how metadata quality positively or negatively impact the collected judgments.  相似文献

厘清众包竞赛中用户之间的竞争关系,有利于了解用户的组织和创新方式,提高众包竞赛的创新效率。以社会网络与随机统计理论为基础,将竞争网络演化驱动因素归纳网络结构属性、节点属性及网络关系属性三个维度,基于猪八戒网相关数据构建用户竞争网络,分析用户竞争网络演化特征,并采用指数随机图模型探究众包竞赛用户竞争网络演化的驱动机制。研究表明:竞争网络呈现“高密度,短路径”的特点,小世界特性显著,且竞争网络结构趋于稳定;竞争网络倾向于形成星型结构与闭合三角结构;众包竞赛用户的成交额、竞争强度及结构洞属性有助于网络形成与演化;用户之间的技术结构邻近性与组织邻近性在竞争网络关系形成中发挥显著作用,而经济距离负向影响竞争网络的形成。  相似文献
