Opinion Dynamics on Discourse Sheaves

Discourse Level Opinion Interpretation

This work proposes opinion frames as a representation of discourse-level associations which arise from related opinion topics. We illustrate how opinion frames help gather more information and also assist disambiguation. Finally we present the results of our experiments to detect these associations.

On symmetric continuum opinion dynamics

This paper investigates the asymptotic behavior of some common opinion dynamicmodels in a continuum of agents. We show that as long as the interactions among the agents aresymmetric, the distribution of the agents’ opinion converges. We also investigate whether conver-gence occurs in a stronger sense than merely in distribution, namely, whether the opinion of almostevery agent c...

Discourse-level Relations for Opinion Analysis

Discourse Level Opinion Relations: An Annotation Study

This work proposes opinion frames as a representation of discourse-level associations that arise from related opinion targets and which are common in task-oriented meeting dialogs. We define the opinion frames and explain their interpretation. Additionally we present an annotation scheme that realizes the opinion frames and via human annotation studies, we show that these can be reliably identi...

Appraisal of Opinion Expressions in Discourse

Opinions are the common stock of conversation; and yet, like many facets of every day life, they are difficult to analyze precisely. Roughly, research in sentiment analysis comes in two flavors: a psychological one and a computational one. Psychologists propose cognitive theories of emotions and affect of various sorts. We distinguish three main approaches: the discrete approach where emotions ...
