Ten Years of REFSQ: a Quantitative Analysis

In its first ten editions, the REFSQ workshop has published over 150 papers on various aspects of Requirements Engineering. In this paper, we apply statistical lexical analysis techniques to this large corpus, in order to characterize the main topics and trends that have emerged from ten years of research in this area. The results provide both an historical perspective (and some lesson) on the evolution of favored research topics, as well as suggestions for the future, in particular about topics that have not been adequately addressed so far.
