Abstract: Software evolution is a hot research field in software engineering. Because the open source software has the characteristics of group intelligence development and the process of evolution uncontrollable and not modeling, the traditional validation method can not apply to open source software. This paper proposes a software validation method from semantic function, attempts to cluster the codes in the way of the topic, and each topic presents a function module in software system. This paper transfers the evolving validation into finding the mapping relation between the function module and the requirements of software evolution. Finally, this paper takes advantage of source codes in open software, makes experiment and gets many actual data, then analyzes these data, the results make clear that the proposed method is better than the comparison method in distinguishing whether evolved or not, and it can be used to verify the software evolution.

Key words: software evolution, validation, topic model, open source software
