  This paper provides a global vision of the scientific publications related
with the Systemic Lupus Erythematosus (SLE), taking as starting point abstracts
of articles. Through the time, abstracts have been evolving towards higher
complexity on used terminology, which makes necessary the use of sophisticated
statistical methods and answering questions including: how vocabulary is
evolving through the time? Which ones are most influential articles? And which
one are the articles that introduced new terms and vocabulary? To answer these,
we analyze a dataset composed by 506 abstracts and downloaded from 115
different journals and cover a 18 year-period.
