This collaborative project between the University of Utah and New York University consists of tools and infrastructure that supports the process of sharing, testing and re-using scientific experiments and results by leveraging and extending the infrastructure provided by provenance-enabled scientific workflow systems. The project explores three key research questions: 1) How to package and publish compendia of scientific results that are reproducible and generalizable. 2) What are appropriate algorithms and interfaces for exploring, comparing, re-using the results or potentially discovering better approaches for a given problem? 3) How to aid reviewers to generate experiments that are most informative given a time/resource limit.

An expected result of this work is a software infrastructure that allows authors to create workflows that encode the computational processes that derive the results (including data used, configuration parameters set, and underlying software), publish and connect these to publications where the results are reported. Testers (or reviewers) can repeat and validate results, ask questions anonymously, and modify experimental conditions.  Researchers, who want to build upon previous works, are able to search, reproduce, compare and analyze experiments and results. The infrastructure helps scientists in any discipline to construct, publish and share reproducible results.

VisTrails 2.0 allows the inclusion of reproducible results in LaTeX/PDF documents. We provide a LaTeX package that allows users to add links to their results in the LaTeX source. For example:  
 
<code>
\usepackage{vistrails}
 
...
 
\begin{figure}
 
\begin{center}
 
\subfigure[a=0.9]{\vistrail[filename=alps.vt, version=2, pdf]{width=8cm}}
 
\subfigure[a=0.9]{\vistrail[filename=alps.vt, version=11, pdf,buildalways]{width=8cm}}
 
\caption{A figure produced by an ALPS VisTrails workflow. Clicking the figure retrieves the workflow used to
create it. Opening that workflow on a machine with VisTrails and ALPS installed lets the reader execute the full calculation.}
 
\end{center}
 
\end{figure}
</code>
 
Once the LaTeX document is compiled, the figure in the PDF becomes active, and when clicked, it will invoke VisTrails and reproduce the result.
You can also upload your results to [http://www.crowdlabs.org CrowdLabs] and export them to Web sites or Wikis, where users can interact with them through a Web browser. See e.g., http://www.crowdlabs.org/vistrails/medleys/details/26/

Project Description

A hallmark of the scientific method has been that experiments should be described in enough detail that they can be repeated and perhaps generalized. This implies the ability to redo experiments in nominally equal settings and also to test the generalizability of a claimed conclusion by trying similar experiments in different settings. In principle, this should be easier for computational experiments than for natural science experiments, because not only can computational processes be automated but also computational systems do not suffer from the 'biological variation' that plagues the life sciences. Unfortunately, the state of the art falls far short of this goal. Most computational experiments are specified only informally in papers, where experimental results are briefly described in figure captions; the code that produced the results is seldom available; and configuration parameters change results in unforeseen ways. Because important scientific discoveries are often the result of sequences of smaller, less significant steps, the ability to publish results that are fully documented and reproducible is necessary for advancing science. While concern about repeatability and generalizability cuts across virtually all natural, computational, and social science fields, no single field has identified this concern as a target of a research effort.

This project is developing a suite of tools and infrastructure that supports the process of sharing, testing and re-using scientific experiments and results by leveraging and extending the infrastructure provided by provenance-enabled scientific workflow systems. The project explores three key research questions: 1) How to package and publish compendia of scientific results that are reproducible and generalizable. 2) What are appropriate algorithms and interfaces for exploring, comparing, re-using the results or potentially discovering better approaches for a given problem? 3) How to aid reviewers to generate experiments that are most informative given a time/resource limit.

An expected result of this work is a software infrastructure that allows authors to create workflows that encode the computational processes that derive the results (including data used, configuration parameters set, and underlying software), publish and connect these to publications where the results are reported. Testers (or reviewers) can repeat and validate results, ask questions anonymously, and modify experimental conditions. Researchers, who want to build upon previous works, are able to search, reproduce, compare and analyze experiments and results. The infrastructure helps scientists in any discipline to construct, publish and share reproducible results.

What scientists are doing about reproducibility

  • The journal Biostatistics has an associate editor for reproducibility who can assign grades of merit to conditionally accepted papers: D: data are available, C: code is available, and R: the AE could run the code and reproduce the results without much effort. (http://magazine.amstat.org/blog/2011/01/01/scipolicyjan11)

Infrastructure to Create Provenance-Rich Papers

The first prototype of our infrastructure is described in http://www.vistrails.org/index.php/ExecutablePapers. We have also written a paper that will appear in the Proceedings of the International Conference on Computational Science, 2011: http://www.cs.utah.edu/~juliana/pub/vistrails-executable-paper.pdf

To see our infrastructure in action, check out the videos and tutorial below.

VisTrails 2.0 allows the inclusion of reproducible results in LaTeX/PDF documents. We provide a LaTeX package that allows users to add links to their results in the LaTeX source. For example:

\usepackage{vistrails}

...

\begin{figure}

\begin{center}

\subfigure[a=0.9]{\vistrail[filename=alps.vt, version=2, pdf]{width=8cm}}

\subfigure[a=0.9]{\vistrail[filename=alps.vt, version=11, pdf,buildalways]{width=8cm}}

\caption{A figure produced by an ALPS VisTrails workflow. Clicking the figure retrieves the workflow used to create it. Opening that workflow on a machine with VisTrails and ALPS installed lets the reader execute the full calculation.}

\end{center}

\end{figure}

Once the LaTeX document is compiled, the figure in the PDF becomes active, and when clicked, it will invoke VisTrails and reproduce the result. You can also upload your results to CrowdLabs and export them to Web sites or Wikis, where users can interact with them through a Web browser. See e.g., http://www.crowdlabs.org/vistrails/medleys/details/26/

SIGMOD Repeatability Effort

As part of this project, in collaboration with Philippe Bonnet, we are using (and extending) our infrastructure to support the SIGMOD Repeatability effort.


Below are some case studies that illustrate how authors can create provenance-rich and reproducible papers, and how reviewers can both reproduce the experiments and perform workability tests:
