The Stanford Dependencies are a deep syntactic representation that are widely used for semantic tasks, like Recognizing Textual Entailment. But do they capture all of the semantic information a meaning representation ought to convey? This pa- per explores this question by investigating the feasibility of mapping Stanford depen- dency parses to Hobbsian Logical Form, a practical, event-theoretic semantic rep- resentation, using only a set of determin- istic rules. Although we find that such a mapping is possible in a large number of cases, we also find cases for which such a mapping seems to require information be- yond what the Stanford Dependencies en- code. These cases shed light on the kinds of semantic information that are and are not present in the Stanford Dependencies.
