The results tend to confirm the original finding since ... decision point will always be at the end of the sentence. Therefore, local ambiguities involving the point of attachment of preposed constituents will not involve parsing indeterminacy u...

Rather, in or- der to distinguish a maximum number of readings, pre-modifiers must attach to the last conjunct and post-modifiers and coordinating conjunctions ... verb, preposition and head noun into a triple, and thus only count content words in the evaluation. For learning, the matter can be resolved empirically: 2 Even in thi...

... focused on applying lexical seman- tics in parsing and PP attachment tasks. Below, we outline these tasks. Parsing As our baseline parsers, we use two state-of-the- art lexicalised parsing models, ... represen- tations in the future. 4 Experimental setting We evaluate the performance of our approach in two settings: (1) full parsing, and (2) PP attachment within a full parsi...

A more general and useful primitive in a typed language with such chains is suspending until ... suspending until a variable is instantiated, and (2) suspending until two variables are equated or inequated. The latter corresponds exactly to structure-sharing in TFSs, and to sha...

An account in terms of template morphology as in [Simpson and Withgott, 1986] could handle the rigid ordering ... If clitic climbing occurs as in (4a), there is ar- gument raising and the right hand side (output) of the lexical rule will account for it; in this specific case the restruct...
