Most Influential Paper Award for CISPA Faculty Andreas Zeller
Andreas Zeller has been honored with yet another Most Influential Paper Award from the MSR conference in Melbourne. Andreas received the award for his paper “The impact of tangled code changes”, which he presented together with Kim Herzig at the MSR in 2013. The jury considers this paper to have been the most influential publication of that conference.
What's the paper about, in brief?
Developers are continuously carrying out code changes, for example when fixing bugs. These changes can be tracked in the version history, allowing for an analysis of the program parts that were fixed repeatedly and would therefore seem especially vulnerable. In their paper “The impact of tangled code changes”, Zeller and Herzig show that committing several unrelated code changes in a single transaction has an adverse effect on bug counting models: Changes appear to be related even if they are not, leading to noise in the version history and compromising the data quality. The paper pleads the case for a better organization of code changes.
