  While numerous attempts have been made to jointly parse syntax and semantics,
high performance in one domain typically comes at the price of performance in
the other. This trade-off contradicts the large body of research focusing on
the rich interactions at the syntax-semantics interface. We explore multiple
model architectures which allow us to exploit the rich syntactic and semantic
annotations contained in the Universal Decompositional Semantics (UDS) dataset,
jointly parsing Universal Dependencies and UDS to obtain state-of-the-art
results in both formalisms. We analyze the behaviour of a joint model of syntax
and semantics, finding patterns supported by linguistic theory at the
syntax-semantics interface. We then investigate to what degree joint modeling
generalizes to a multilingual setting, where we find similar trends across 8
languages.
