Deontic Modality

Deontic Modality of Imperatives

Deontic modality based on preference

Deontic modalities are here defined in terms of the preference relation explored in our previous work (Osherson and Weinstein, 2012). Some consequences of the system are discussed.

The Author Perspective Model for Classifying Deontic Modality in Events

In this paper we present a generative model entitled the Author Perspective Model for the classification of deontic modality in event mentions. In the model modals, adverbials, and predicates associated with an event mention are generated by either a topic or author perspective where the author perspective is one of the three high level categories of deontic modality. We train the model with da...

Deontic Modality, Lexical Aspect and the Semantics of Imperatives

Deontic norms, deontic reasoning, and deontic conditionals

Deontic reasoning is thinking about whether actions are forbidden or allowed, obligatory or not obligatory. It is proposed that social norms, imposing constraints on individual actions, constitute the fundamental concept for the system of these four deontic modalities, and that people reason from such norms flexibly according to deontic core principles. Two experiments are presented, one on deo...
