The Atlantic subpolar gyre (SPG) is one of the main drivers of decadal climate variability in the North Atlantic. Here we analyze its dynamics in pre-industrial control simulations of 19 different comprehensive coupled climate models. The analysis is based on a recently proposed description of the SPG dynamics that found the circulation to be potentially bistable due to a positive feedback mech...

In this paper, we propose a new method to expand an examplebased spoken dialogue system to handle context dependent utterances. The dialogue system refers to the dialogue examples to find an example that is suitable to promote dialogue. Here, the dialogue contexts are expressed in the form of dialogue slots. By constructing dialogue examples with the text of utterances and the dialogue slots, t...

this study investigated the effect of oral dialogue journals on communicative competence of iranian efl learners. participants of this study were 80 students of two payam-e-noor universities who were proved to be homogenous in the communicative competence based on tse (test of spoken english) interview. the participants of one of these universities were considered as the experimental group. the...

Dialogue act classification is a central challenge for dialogue systems. Although the importance of emotion in human dialogue is widely recognized, most dialogue act classification models make limited or no use of affective channels in dialogue act classification. This paper presents a novel affect-enriched dialogue act classifier for task-oriented dialogue that models facial expressions of use...

The Dialogue-based Reflective Learning System for Historical Text Comprehension consists of two parts: (1) the Diagnosis and (2) the Reflective Tutorial Dialogue. In this paper we present the knowledge representation in the dialogue generator module of the Reflective Tutorial Dialogue System (ReTuDiS), which is based on the Theory of Inquiry Teaching. The dialogue generator uses dialogue strate...
