A theme structure method for the ellipsis resolution
نویسندگان
چکیده
The purpose of this paper is to solve the contextual ellipsis problem that is popular in our Chinese spoken dialogue system named EasyNav. A Theme Structure is proposed to describe the attentional state. Its dynamic generation feature makes it suitable to model the topic transition in user-initiative dialogues. By studying the differences and the similarities between the ellipsis and the anaphora phenomena, we extend the resolution procedure and the theory from anaphora to ellipsis. The ellipsis resolution is now based on the semantic knowledge and the discourse factor other than the syntactic information. A Theme Structure Method proposed in this paper for the ellipsis resolution is uniform to not only all kinds of elliptical elements but also some particular ellipsis types such as the fragmental ellipsis and the default ellipsis.

The existence of ellipsis under certain constructions is often disguised due to the structure that assigns the nominative marking to what is typically the object. This kind of ellipsis deserves attention in view of the fact that its referent is the agent of the sentence and that these constructions are observed in diverse ...

This study aspires to examine the concept of ellipsis by comparing and contrasting English and Persian written texts. For this purpose, three Persian novels and three English ones were selected. These novels were analyzed carefully; they were compared and contrasted for types and amount of ellipsis used, through a Chi-square analysis. The results of the data analysis revealed that various t...
متن کاملFeasibility Study for Ellipsis Resultion in Dialogues by Machine-Learning Technique
A method for resolving the ellipses that appear in Japanese dialogues is proposed. This method resolves not only the subject ellipsis, but also those in object and other grammatical cases. In this approach, a machine-learning algorithm is used to select the attributes necessary for a resolution. A decision tree is built, and used as the actual ellipsis resolver. The results of blind tests have ...
متن کاملInteractions of scope and ellipsis
Systematic semantic ambiguities result from the interaction of the two operations that are involved in resolving ellipsis in the presence of scoping elements such as quantiiers and intensional operators: scope determination for the scoping elements and resolution of the elided relation.

Despite the body of research on textbook evaluation from the discourse analysis perspective, cohesive devices have rarely been analyzed in English for Specific Purposes (ESP) textbooks. The acquisition and use of cohesive devices is inherent to naturalistic communication, including business interactions. Hence, L2 learners of business English should be exposed to these devices through cohesion-...
