We present a novel scheme for annotating the realization and ellipsis of Korean particles. Annotated data include 100,128 Ecel (a spacebased word unit) in spoken and written corpora composed of four different genres in order to evaluate how register variation contributes to Korean particle ellipsis. Identifying the grammatical functions of particles and zero particles is critical for deriving a...

Domain-independent meaning representation of text has received a renewed interest in the NLP community. Comparison plays a crucial role in shaping objective and subjective opinion and measurement in natural language, and is often expressed in complex constructions including ellipsis. In this paper, we introduce a novel framework for jointly capturing the semantic structure of comparison and ell...

Ellipsis is a linguistic process that makes certain aspects of text meaning not directly traceable to surface text elements and, therefore, inaccessible to most language processing technologies. However, detecting and resolving ellipsis is an indispensable capability for language-enabled intelligent agents. The key insight of the work presented here is that not all cases of ellipsis are equally...

In this paper, we describe RitsQA: Ritsumeikan question answering system. We have improved our QA system submitted in QAC1 in subcategorization of NE type and question type analysis and in handling numerical expressions using corpus based approach. We also participated subtask 2 and 3 using these core QA systems. We have implemented list answer detection module for subtask 2 and ellipsis handli...

Investigations of sluicing since Chung, Ladusaw, and McCloskey 1995 have profitably explored two approaches to this ellipsis process that differ significantly from ours. In one, the ellipsis site is created by deletion of a fully articulated TP in which Wh -movement has applied. In the other, the ellipsis site contains no internal structure at all, and its reference is resolved via pragmatic in...

A computational account of VP ellipsis is described, in which VP's are represented in the discourse model as contextually dependent semantic objects. It is argued that this approach can handle examples that are not allowed by alternative accounts. An implementation is defined in terms of extensions to the Incremental Interpretation System. The treatment of VP ellipsis is analogous to that of pr...

This paper describes how intelligent agents modeled within the OntoAgent cognitive architecture treat the linguistic phenomenon of modal scope ellipsis. The approach offers two innovative aspects with respect to cognitive modeling: (1) ellipsis treatment is distributed across processing modules in a psychologically plausible way and (2) agents are prepared to incorporate calculations of utility...

VP-ellipsis and pseudogapping in English show a previously unnoticed asymmetry in their tolerance for voice mismatch: while VP-ellipsis allows mismatches in voice between the elided VP and its antecedent, pseudogapping does not. This difference is unexpected under current analyses of pseudogapping, which posit that pseudogapping is a kind of VP-ellipsis. I show that this difference falls out na...

The paper presents a type of ellipsis similar to stripping and split conjuncts, yet irreducible to either of them. One aim of the analysis is to document the existence of this distinct ellipsis type within the class of constructions where the elided constituent is a verb or a verb phrase. It is argued that the main generative strategies, namely, deletion and null anaphora cannot be applied to t...
