Towards a more accurate assessment of file authorship

Measuring the number of authors and establishing the main developer of the files belonging to a software system are very important activities. Currently there are different approaches for measuring these characteristics. In this paper we compare the results provided by a well-known approach against an approach that, to the best of our knowledge, was not previously employed. The comparison is performed against a suite of nine popular open source systems and reveals that in many cases there are significant differences among the provided results.
