A Corpus Of Java Projects Representing The 2012 Ohloh Universe

A corpus of Java projects build using the Software Projects Sampling (SPS) tool by Naggapan et al [1]. SPS measures representativeness of a smaller corpus with respect to the universe (Ohloh 2012) in terms of diversity dimensions and constructs a maximally representative corpus by iteratively adding projects that would increase the representativeness most. The corpus contains the source code of the projects selected at 1 June 2012. This is due to the fact that the Ohloh data on which the diversity was calculated was of that period. [1] M. Nagappan, T. Zimmermann, and C. Bird, “Diversity in software engineering research,” in ESEC/FSE. ACM, 2013, pp. 466–476.
