In this paper, we revisit the dependence language model for information retrieval proposed in [1] , and show that this model is deficient from a theoretical point of view. We then propose a new model, well founded theoretically, for integrating dependencies between terms in the language model. This new model is simpler, yet more general, than the one proposed in [1], and yields similar results in our experiments, on both syntactic and semantic dependencies.
