项目摘要

Scientific reproducibility -- the ability to independently verify the work of other scientists -- continues to be a critical barrier towards achieving the vision of cross-disciplinary science. Federal agencies and publishers increasingly mandate and incentivize scientists to, at a minimum, establish computational reproducibility of scientific experiments. To comply scientists must connect descriptions of scientific experiments in scholarly publications with the underlying data and code used to produce the published results and findings. However, in practice, computational reproducibility is hard to achieve since it entails isolating necessary and sufficient computational artifacts and then preserving those artifacts in a standard way for later re-execution. Both isolation and preservation present challenges in large part due to the complexity of existing software and systems as well as the implicit dependencies, resource distribution, and shifting compatibility of systems that evolve over time -- all of which conspire to break the reproducibility of an experiment. The goal of the GeoTrust project is to understand the research lifecycle of scientific experiments from conception to publication and establish a framework that will improve their reproducibility. GeoTrust will develop sandboxing-based systems and tools that help scientists effectively isolate computational artifacts associated with an experiment, use languages and semantics to preserve artifacts, and re-execute /reproduce experiments by deploying the artifacts, changing datasets, algorithms, models, environments, etc. This reproducible framework will be adopted by and integrated within community infrastructures of three geoscience sub-disciplines viz. Hydrology, Solid Earth, and Space Science. Using cross-disciplinary science uses cases from these sub-disciplines, and engaging independent evaluators, we will assess the effectiveness of the framework in achieving reproducibility of computational experiments. Finally, verified results will be associated with ?stamps of reproducibility?, establishing community recognition of computational experiments. The framework will be developed as an EarthCube capability, with software developed and released as per EarthCube requirements. Early adopters across other geoscience sub-disciplines will be continually sought.

科学的可重复性 - 独立验证其他科学家的工作的能力 - 仍然是实现跨学科科学愿景的关键障碍。联邦机构和出版商越来越多地授权，并激励科学家至少建立了科学实验的计算可重复性。为了遵守科学家，必须将学术出版物中科学实验的描述与用于产生已发表结果和发现的基础数据和代码联系起来。但是，在实践中，很难实现计算可重复性，因为它需要隔离必要和足够的计算伪像，然后以标准方式保留这些工件以进行后期重新执行。隔离和保存在很大程度上是由于现有软件和系统的复杂性以及隐性依赖性，资源分布以及随着时间的推移而发展的系统的兼容性的变化 - 所有这些都共同促进了所有这些实验的可重复性。 Geotrust项目的目标是了解从概念到出版的科学实验的研究生命周期，并建立一个可以提高其可重复性的框架。 GeoTrust将开发基于沙箱的系统和工具，以帮助科学家有效隔离与实验相关的计算文物，使用语言和语言来保留工件，并重新执行 /再现实验，通过部署工件，通过部署工件，更改数据集，算法，模型，环境，环境，环境，环境，环境，环境，综合框架，进行。子学科。水文，地球和太空科学。使用跨学科科学使用这些子学科的案例以及引人入胜的独立评估者，我们将评估该框架在实现计算实验可重复性方面的有效性。最后，经过验证的结果将与“可重复性”邮票相关联？建立了对计算实验的社区认可。该框架将作为EarthCube功能开发，并根据EarthCube要求开发和发布软件。其他地球科学子学科的早期采用者将不断寻求。
