More recently, as an end-to-end model considering multi-predicate dependencies, <cite>Ouchi et al. (2017)</cite> used Grid RNN to incorporate intermediate representations of the prediction for one predicate generated by an RNN layer into the inputs of the RNN layer for another predicate. However, in this model, since the information of multiple predicates also propagates through the RNNs, the integration of the prediction information is influenced by word order and distance, which is not necessarily important for aspects of syntactic and semantic relations.
