A dataset of clone references with gaps

This paper introduces a new dataset of clone references, which is a set of correct clones consisting of their locational information with their gapped lines. Bellon's dataset is one of widely used clone datasets. Bellon's dataset contains many clone references, thus the dataset is useful for comparing accuracies among clone detectors. However, Bellon's dataset does not have locational information of gapped lines. Thus, Bellon's benchmark does not evaluate some Type-3 clones correctly. In order to resolve the problem, we added locational information of gapped lines to Bellon's dataset. The new dataset is available at ``http://sdl.ist.osaka-u.ac.jp/~h-murakm/2014_clone_references_with_gaps/''.
