How have the themes of the first 99 issues of the BMS evolved, An analysis with a text-mining software: The titles, abstracts (in French) and key words (in French) of the 315 articles published in issues 1 to 99 of the BMS from 1983 to 2008 were divided into three periods: 1983-1992 (85 articles), 1993-2000 (119 articles) and 2001-2008 (111 articles). These three corpora were individually analyzed with Calliope, an analysis by co-occurrence of key words in units of text, which produces thematic clusters. It also constructs strategic diagrams, which show the general thematic structure of each period with its axes of density (ties within a thematic cluster) and centrality (external ties between clusters). These diagrams, and those of the more dominant clusters, are presented along with their interpretation
