We are happy to announce that our paper "Addressing Problems with Replicability and Validity of Repository Mining Studies through a Smart Data Platform" was accepted for publication by Springer Empirical Software Engineering.  Within this article, four major problems in the state of practice of software repository mining that threaten the external validity of research results, i.e., the generalizability of drawn conclussions, are discussed. This article is an extension to our MSR publication.
The pre-print of the article is available online at Springer. A free view-only version of the article is available here.
 

We are happy to announce that our paper A Comparative Study to Benchmark Cross-project Defect Prediction Approaches was accepted for publication by the IEEE Transactions on Software Engineering - the top journal for the field of software engineering. 
 
Within this article, we compared 24 approaches for cross-project defect prediction proposed between 2008 and 2015. Most of these approaches were never replicated or compared to each other before. Our suprising findings show that very little actual progress was made in the state of the the art since 2009, if we considered multiple performance metrics and data sets. 

The pre-print of the article is available in IEEE Xplore and thanks to the green open access policy of the IEEE on our homepage.
