A team of experts from five institutions (University of Minnesota, Adler Planetarium, University of Wyoming, Colorado State University, and UC San Diego) links field-based and online analysis capabilities to support citizen science, focusing on three research areas (cell biology, ecology, and astronomy). The project builds on Zooniverse and CitSci.org, leverages the NSF Science Gateways Community Institute, and enhances the quality of citizen science and the experience of its participants.This project creates an integrated Citizen Science Cyberinfrastructure (CSCI) framework that expands the capacity of research communities across several disciplines to use citizen science as a suitable and sustainable research methodology. CSCI produces three improvements to the infrastructure for citizen science already provided by Zooniverse and CitSci.org: - Combining Modes - connecting the process of data collection and analysis; - Smart Assignment - improving the assignment of tasks during analysis; and - New Data Models - exploring the Data-as-Subject model. By treating time series data as data, this model removes the need to create images for classification and facilitates more complex workflows. These improvements are motivated and investigated through three distinct scientific cases: - Biomedicine (3D Morphology of Cell Nucleus). Currently, Zooniverse 'Etch-a-Cell' volunteers provide annotations of cellular components in images from high-resolution microscopy, where a single cell provides a stack containing thousands of sliced images. The Smart Task Assignment capability incorporates this information, so volunteers are not shown each image in a stack where machines or other volunteers have already evaluated some subset of data. - Ecology (Identifying Individual Animals). When monitoring wide-ranging wildlife populations, identification of individual animals is needed for robust estimates of population sizes and trends. This use case combines field collection and data analysis with deep learning to improve results. - Astronomy (Characterizing Lightcurves). Astronomical time series data reveal a variety of behaviors, such as stellar flares or planetary transits. The existing Zooniverse data model requires classification of individual images before aggregation of results and transformation back to refer to the original data. By using the Data-as-Subject model and the Smart Task Assignment capability, volunteers will be able to scan through the entire time series in a machine-aided manner to determine specific light curve characteristics.The team explores the use of recurrent neural networks (RNNs) to determine automated learning architectures best suited to the projects. Of particular interest is how the degree to which neighboring subjects are coupled affects performance. The integration of existing tools, which is based on application programming interfaces (APIs), also facilitates further tool integration. The effort creates a citizen science framework that directly advances knowledge for three science use cases in biomedicine, ecology, and astronomy, and combines field-collected data with data analysis. This has the ability to solve key problems in the individual applications, as well as benefiting the research of the dozens of projects on the Zooniverse platform. It provides benefits to researchers using citizen scientists, and to the nearly 1.6 million citizen scientists themselves.This award by the Office of Advanced Cyberinfrastructure is jointly supported by the Division of Research on Learning in Formal and Informal Settings, within the NSF Directorate for Education and Human Resources.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

来自五个机构（明尼苏达大学、阿德勒天文馆、怀俄明大学、科罗拉多州立大学和加州大学圣地亚哥分校）的专家团队将现场分析和在线分析能力结合起来，以支持公民科学，重点关注三个研究领域（细胞生物学、生态学、天文学）。 该项目以 Zooniverse 和 CitSci.org 为基础，利用 NSF Science Gateways 社区研究所，提高公民科学的质量及其参与者的体验。该项目创建了一个综合的公民科学网络基础设施 (CSCI) 框架，扩大了研究能力跨多个学科的社区将公民科学作为一种合适且可持续的研究方法。 CSCI 对 Zooniverse 和 CitSci.org 已经提供的公民科学基础设施进行了三项改进： - 组合模式 - 连接数据收集和分析的过程； - 智能分配——改进分析过程中的任务分配； - 新数据模型 - 探索数据作为主体模型。 通过将时间序列数据视为数据，该模型消除了创建用于分类的图像的需要，并促进了更复杂的工作流程。 这些改进是通过三个不同的科学案例来激发和研究的： - 生物医学（细胞核的 3D 形态）。 目前，Zooniverse 的“Etch-a-Cell”志愿者提供高分辨率显微镜图像中细胞成分的注释，其中单个细胞提供包含数千个切片图像的堆栈。 智能任务分配功能合并了这些信息，因此志愿者不会看到堆栈中的每个图像，其中机器或其他志愿者已经评估了某些数据子集。 - 生态学（识别个体动物）。 在监测广泛的野生动物种群时，需要对个体动物进行识别，以便对种群规模和趋势进行可靠的估计。 该用例将现场收集和数据分析与深度学习相结合，以改善结果。 - 天文学（表征光曲线）。 天文时间序列数据揭示了各种行为，例如恒星耀斑或行星凌日。 现有的 Zooniverse 数据模型需要在聚合结果之前对各个图像进行分类，并转换回原始数据。 通过使用数据作为主体模型和智能任务分配功能，志愿者将能够以机器辅助的方式扫描整个时间序列，以确定特定的光变曲线特征。该团队探索了循环神经网络的使用（ RNN）来确定最适合项目的自动化学习架构。 特别令人感兴趣的是相邻主题的耦合程度如何影响性能。基于应用程序编程接口（API）的现有工具的集成也有利于进一步的工具集成。 这项工作创建了一个公民科学框架，直接推进生物医学、生态学和天文学三个科学用例的知识，并将现场收集的数据与数据分析相结合。这有能力解决单个应用中的关键问题，也有利于Zooniverse平台上数十个项目的研究。它为使用公民科学家的研究人员以及近 160 万公民科学家本身提供了好处。该奖项由高级网络基础设施办公室颁发，并得到美国国家科学基金会教育和非正式理事会正式和非正式环境学习研究部的共同支持。人力资源。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
