In contrast to the previous model, it does not model the interaction between arguments: it is easy to see that p(e 1 |e 2 , r, θ) for this model (expression (2)) does not depend on e 2 (i.e., on u e 2 and c 2r ).
such a decoder would be more similar to generative models of relations which typically assume that arguments are conditionally independent (Yao et al., 2011).
