One deficiency of current shallow parsing based Semantic Role Labeling (SRL) methods is that syntactic chunks are too small to effectively group words. To partially resolve this problem, we propose semantics-driven shallow parsing, which takes into account both syntactic structures and predicate-argument structures. We also introduce several new “path” features to improve shallow parsing based ...

We present a case study on the role of syntactic structures towards resolving the Semantic Textual Similarity (STS) task. Although various approaches have been proposed, the research of using syntactic information to determine the semantic similarity is a relatively under-researched area. At the level of syntactic structure, it is not clear how significant the syntactic structure contributes to...

The paper develops a constraint-based theory of prosodic phrasing and prominence, based on an HPSG framework, with an implementation in ALE. Prominence and juncture are represented by n-ary branching metrical trees. The general aim is to define prosodic structures recursively, in parallel with the definition of syntactic structures. We address a number of prima facie problems arising from the d...

Using data from a range of Australian languages, in this paper we argue for an analysis of various nominal appositional structures as syntactic coordinations (i.e. as hybrid f-structures) in LFG. We show that this provides a simple and straightforward account of the surface syntactic similarities among a range of juxtaposed construction types, while the differences between the constructions can...

Structural ambiguity is one of the most difficult problems in natural language processing. Two disambiguation mechanisms for unrestricted text analysis are commonly used: lexical knowledge and context considerations. Our parsing method includes three different mechanisms to reveal syntactic structures and an additional voting module to obtain the most probable structures for a sentence. The dev...

Argument structure has two faces, semantic and syntactic. On the semantic side, argument structure represents the core participants in events (states, processes) designated by a single predicator. From this point of view it appears as a type of representation of event structure. On the syntactic side, argument structure represents the minimal information needed to characterize the syntactic dep...

The goal of this investigation is the develop­ ment of a semantics for 1 order theories based on certain new syntactic structures in formal proofs which derive from their pragmatic and semantic aspects. The present report is mainly concerned with these new syntactic structures, the motivation behind them, their technical def­ inition and their basic properties. Their role in a new semantics for...

This paper proposes a statistical, treeto-tree model for producing translations. Two main contributions are as follows: (1) a method for the extraction of syntactic structures with alignment information from a parallel corpus of translations, and (2) use of a discriminative, featurebased model for prediction of these targetlanguage syntactic structures—which we call aligned extended projections...
