From these examples, as long as we create two nodes in the DAG corresponding to each plural chunk, and one node corresponding to each negation, there is no need to modify the underlying model (defined in the previous section).
when u (or v) is a negation (N i) or an implicit universal (id) node, the probabilities p λ u,v (λ ∈ {+, −, }) may come from a different source, e.g.
