ReproZip: Using Provenance to Support Computational Reproducibility

We describe ReproZip, a tool that makes it easier for authors to publish reproducible results and for reviewers to validate these results. By tracking operating system calls, ReproZip systematically captures detailed provenance of existing experiments, including data dependencies, libraries used, and configuration parameters. This information is combined into a package that can be installed and run on a different environment. An important goal that we have for ReproZip is usability. Besides simplifying the creation of reproducible results, the system also helps reviewers. Because the package is self contained, reviewers need not install any additional software to run the experiments. In addition, ReproZip generates a workflow specification for the experiment. This not only enables reviewers to execute this specification within a workflow system to explore the experiment and try different configurations, but also the provenance kept by the workflow system can facilitate communication between reviewers and authors.
