In this paper, we propose ellipsis handling method for follow-up questions in Information Access Dialogue (IAD) task of NTCIR QAC3. In this method, our system classifies ellipsis patterns of question sentences into three types and recognizes elliptical elements using ellipsis handling algorithm for each type. In the evaluation using Formal Run and Reference Run data, there were several cases wh...

Interpreting a verb-phrase ellipsis (VP ellipsis) requires accessing an antecedent in memory, and then integrating a representation of this antecedent into the local context. We investigated the online interpretation of VP ellipsis in an eye-tracking experiment and four speed–accuracy tradeoff experiments. To investigate whether the antecedent for a VP ellipsis is accessed with a search or dire...

Exposure to verb phrase ellipsis in English with double-object or prepositional ditransitive antecedents affects syntactic choices in subsequent sentence production, inducing speakers to favor the production of structures parallel to that to which the ellipsis is anaphoric. This result is readily explanable only if ellipsis sites contain or trigger access to syntactic structure (which causes pr...

The nature of ellipsis resolution has long been the topic of a heated discussion in the linguistics literature. Ellipsis is a widespread linguistic phenomenon. I show here that an adequate account of ellipsis will have to make use of context in the sense of previous discourse. “Syntactic” accounts of ellipsis are no way out of this. This will be an argument for contextualists who claim that “wh...

One job of the ellipsis theorist is to characterize the connection between the syntax of ellipsis and its semantics. And a central goal of that task is to explain where it is that ellipses are possible. The most thorough examination of what’s involved in meeting this goal is probably Lobeck (1995), where it is proposed that heads with certain properties license the ellipsis of their complements...

It is generally assumed that ellipsis requires certain parallelism between the clause containing the ellips is and some antecedent clause. We argue that the parallelism requirement generated by ellipsis must be applied in accordance with discourse structure: a matching antecedent clause must be found that locally c-commands the clause containing the ellipsis in the discourse tree. We show that ...

What knowledge sources are necessary in the interpretation and generation of ellipsis? After a short background on earlier approaches we compare and discuss each of the four papers selected for this special issue, examining how they approach ellipsis generation or interpretation. We highlight areas where more research needs to be done: outlining how pragmatics affects ellipsis, empirical studie...

We present an algorithm which assigns interpretations to several major types of ellipsis structures through a generalized procedure of syntactic reconstruction. Ellipsis structures are taken to be sequences of lexically realized arguments and/or adjuncts of an empty verbal head. Reconstruction is characterized as the specification of a (partial) correspondence relation between the unrealized he...

In this paper I use the formal framework of minimalist grammars to implement a version of the traditional approach to ellipsis as ‘deletion under syntactic (derivational) identity’, which, in conjunction with canonical analyses of voice phenomena, immediately allows for voice mismatches in verb phrase ellipsis, but not in sluicing. This approach to ellipsis is naturally implemented in a parser ...
