摘要

如果以前的研究(如[5,2])表明大多数IR模型满足大多数IR约束，那么TDC约束的情况是不明确的，本文的目的是表明一些最先进的IR模型确实不符合一般TDC约束，但确实满足特殊TDC约束。我们将在这里回顾最近引入的逻辑-逻辑模型[2]，以及Jelinek-Mercer和Dirichlet语言模型。

Do IR models satisfy the TDC retrieval constraint

If it has been show in previous studies (as [5, 2]) 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.
