However, the knowledge about how this process occurs is not consolidate yet. This paper presents the results of a study about software evolution characterization based on concepts of Complex Networks. We analyzed 16 open-source software systems and one commercial application, in a total of 129 versions. The results of this study show that: the density of a software network decreases as the software system grows; the diameter of such networks is short; the classes with higher in-degree keep this status; such classes are unstable and their internal cohesion degrades. Our investigations also revealed an interesting picture which models the macroscopic structure of software networks. We called it the little house.<\/jats:p>","DOI":"10.5753\/sbqs.2011.15386","type":"proceedings-article","created":{"date-parts":[[2021,7,16]],"date-time":"2021-07-16T10:15:47Z","timestamp":1626430547000},"page":"41-55","source":"Crossref","is-referenced-by-count":3,"title":["Software Evolution Characterization - A Complex Network Approach"],"prefix":"10.5753","author":[{"given":"Kecia A.
