A two-step optimization strategy for relational schemas that contains a class of inclusion dependencies is described. Both steps take into account additional information that indicates how to preserve each inclusion dependency in the presence of insertions an‘d deletioy. The first step eliminates inclusion dependencies which are redundant with respect to both the semantics of the data and the b...

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...

In a constructive learning setting, a robot builds up beliefs about the world by interacting – interacting with the world, and with other agents. Asking questions is key in such a setting. It provides a mechanism for interactively exploring possibilities, to extend and explain the robot’s beliefs. The paper focuses on how to linguistically phrase questions in dialogue. How well the point of a q...

During a narrative discourse, accessibility of the referents is rarely fixed once and for all. Rather, each referent varies in accessibility as the discourse unfolds, depending on the presence and prominence of the other referents. This leads the speaker to use various referential expressions to refer to the main protagonists of the story at different moments in the narrative. This study relies...

Self-referential processing has been principally investigated using functional magnetic resonance imaging (fMRI). However, understanding of the brain functioning is not possible without careful comparison of the evidence coming from different methodological domains. This paper aims to review electroencephalographic (EEG) studies of self-referential processing and to evaluate how they correspond...

Анализируется некогда популярная, но лишенная эпистемологической основности платформа беспредпосылочности строя семантической процедуры. Показывается установление смыслозначимости в вариантах лингвистической, логической, философской семантики с опорой на предпосылочное базисное знание (система допущений о природе осваиваемой концептуально-символическими средствами реальности); последнее, отменя...

In this paper, we present a machine learning system for classifying subject ellipsis in Spanish as either referential or non-referential. To the best of our knowledge, this is the first attempt to automatically identify non-referential ellipsis in Spanish. An evaluation of our system against 6,827 finite verbs shows an accuracy of 87%.
