The dataref versuchung: Saving Time through Better Internal Repeatability

Compared to more traditional disciplines, such as the natural sciences, computer science is said to have a somewhat sloppy relationship with the external repeatability of published results. However, from our experience the problem starts even earlier: In many cases, authors are not even able to replicate their own results a year later, or to explain how exactly that number on page three of the paper was ncomputed. Because of constant time pressure and strict submission deadlines, the successful researcher has to favor timely results over experiment documentation and data traceability. We consider internal repeatability to be one of the most important prerequisites for external replicability and the scientific process. We describe our approach to foster internal repeatability in our own research projects with the help of dedicated tools for the automation of traceable experimental setups and for data presentation in scientific papers. By employing these tools, measures for ensuring internal repeatability no longer waste valuable working time and pay off quickly: They save time by eliminating recurring, and therefore error-prone, manual work steps, and at the same time increase confidence in experimental results.
