In this article, we conduct a data analysis work from the EGC conference. These data includes articles accepted at the EGC since 2004 as well as posts posted on the social network Twitter. Our goal is to highlight, since 2004, the major evolutions of the EGC conference in (i) keywords, (ii) collaborations and (iii) sentiments expressed on Twitter. The results obtained highlight the evolution of the keywords of the conference since 2004, the collaborative schemes that are being set up and their evolution, and the sentiments that emerge from the messages published around the conference on Twitter.
