This paper presents the MADbot architecture which enables a motivated autonomous agent to generate goals in response to changes in its underlying drives or motivations, while it is both planning and executing. We use a Mars rover domain to illustrate the workings of this architecture and describe two ways of modelling motivations and goal generation: the first decouples the model of motivations...

We introduce a simple and effective method to learn discourse-specific word embeddings (DSWE) for implicit discourse relation recognition. Specifically, DSWE is learned by performing connective classification on massive explicit discourse data, and capable of capturing discourse relationships between words. On the PDTB data set, using DSWE as features achieves significant improvements over base...

It is sometimes claimed (cf. that discourse has a tree structure which reeects the semantic structure of discourse. In this paper, I argue that this claim is problematic in cases of discourse multiple dependencies i.e. cases where one discourse segment is semantically related to two discourse segments. I develop a discourse framework which is based on Scha/Polanyi 1988] but integrates ideas fro...
