Polite behavior in intelligent conversational systems requires mixed-initiative dialog. AutoTutor is an intelligent tutoring system in which several of these conversational skills are implemented. This paper discusses some aspects of mixed-initiative dialog, as implemented in AutoTutor ranging from discourse markers, dialog moves and speech acts to question answering. In addition some of the st...

Interactions with conversational systems take diverse forms across applications and individual users. In order to develop intelligent systems that can accommodate these diverse conversational user experience (UX) needs and preferences, meanwhile balancing implementation costs, we propose a computationdriven approach to profile conversational interactions by measuring dialogue complexity of user...

This paper studies the dominance-solvability (by iterated deletion of weakly dominated strategies) of general scoring rule voting games. The scoring rules we study include Plurality rule, Approval voting, Negative Plurality Rule, Borda rule and Relative Utilitarianism. We provide a classification of scoring rule voting games according to whether the sufficient conditions for dominance solvabili...

in order to estimate heritability and gene action for grain yield and its related traits in lentil, six basic generations were evaluated in a randomized complete block design with three replications in a field experiment. besides seed yield per plant, plant height, pod length, and 100-seed weight, the number of pods per plant, primary branches, clusters per plant, nodes per main stem, secondary...

as the arabic formal language is the national unifier that unites the sons of the arabs, so that it is a common language and the one of the holy quran, ideological inherited, and the language of science and knowledge, vulgar dialects in different arab countries, however, differ to the extent that, for example, a man from one of the eastern arab countries isn't able to find out the accent o...

Conventional synthetic voices can synthesise neutral read aloud speech well. But, to make synthetic speech more suitable for a wider range of applications, the voices need to express more than just the word identity. We need to develop voices that can partake in a conversation and express, e.g. agreement, disagreement, hesitation, in a natural and believable manner. In speech synthesis there ar...

Learning/training is an important application domain for intelligent agents technologies supporting believable dialogues and realistic virtual environments. In this paper, we first review, in section 2, some of the current applications and research in technology-enhanced learning. In section 3 we discuss the impact of conversational agents on the design of more effective individual and group/co...

Virtual humans and other virtual agents are becoming more common in our everyday lives. Whether in the form of phone-based personal assistants or automated customer service systems, these technologies have begun to touch more of our activities. This research aims to understand how this technology affects the way we interact with our computer systems. Using a chat bot, I studied the way a conver...

This paper introduces the understanding system HAM-RPM, which simulates a dialogue partner conversing about a real-life domain. After outlining the system's overall structure, we discuss three of its distinguishing features: The first is its organisation of spatial data in a redundant multiple data base, inspired by certain aspects characteristic of visual search in humans. A new algorithm for ...
