In this paper, we describe a set of metrics for the evaluation of different dialogue management strategies in an implemented real-time spoken language system. The set of metrics we propose tries to offer useful insights in evaluating how particular choices in the dialogue management can affect the overall quality of the man-machine dialogue. The evaluation makes use of established metrics: the ...

It has been widely recognized that online opinions constitute important informational sources for consumers and producers. The open nature of communication supported by social media, however, raises an important yet unsettled question of whether and how earlier opinions affect those that come after. This poster presents a model to illustrate the relationship between existing and new reviews. Ba...

The paper aims to demonstrate the importance of behavioural issues in environmental modelling. These issues can relate both to the modeler and to the modelling process including the social interaction in the modelling team. The origins of behavioural effects can be in the cognitive and motivational biases or in the social systems created as well as in the visual and verbal communication strateg...

Based on two popular theoretical frameworks regarding media choices of rational choice and social influence (Markus 1987; Trevino et al. 2000) the main theme of this paper is to investigate applicability of these frameworks on a case where the pattern in usage and collective meaning of a medium is shaped in the cultural context. Focusing on the phenomenon of many Asians preferring not to send e...

We study the classical problem of trade in two-dimensional Euclidean space. It is known that there no efficient rule for this model compatible with dominant strategy incentives, is, and strategy-proof rule. observe that, addition to incentive constraints, informational constraints are also unavoidable social planners. Thus, we impose requirement finite dimensional messages be sufficient informa...

with fκ(s) as large as possible (resp. Fκ(s) as small as possible) given that the above inequality holds for all choices of A satisfying (1). Selberg [2] has shown (in a much more general context) that the functions fκ(s), Fκ(s) are continuous, monotone, and computable for s > 1, that they do not change if we replace (1) with (2), and that they tend to 1 exponentially as s goes to infinity. Mor...

This paper investigates novel methods for incorporating syntactic information in probabilistic latent variable models of lexical choice and contextual similarity. The resulting models capture the effects of context on the interpretation of a word and in particular its effect on the appropriateness of replacing that word with a potentially related one. Evaluating our techniques on two datasets, ...
