If it has been show in previous studies that most
IR models satisfy most IR constraints, the situation of the
TDC constraint is unclear, and the goal of this short paper
is to show that several state-of-the-art IR models indeed do
not comply with the general TDC constraint, but do satisfy
the speTDC one. We will review here the recently intro-
duced log-logistic model [2], as well as the Jelinek-Mercer and Dirichlet language models.
