Automatic Generation of Dialogue Acts: Understanding Dialogue through Computational Modelling

Topic Description

The purpose of this project is to gain a better understanding of human-human dialogue through formal/computational modelling (Piwek, 2011; 2006). It will focus one of the following three phenomena in dialogue:

1) multimodal dialogue acts (involving gesture and speech) (Piwek 2009; Piwek, Beun & Cremers, 2008),
2) generation of questions (Piwek & Boyer, 2012; Kuyten et al., 2012; Rus et al. 2010; Wyse & Piwek, 2009), or
3) adversarial dialogue moves (and emotion) (Pluss, 2014; Pluss, Piwek & Power, 2011).

The main aim of the project will be to construct a computational model of one of these phenomena. This will involve building algorithms for automatically generating dialogue acts that exhibit the relevant phenomenon (for example, a model for automatically generating questions or, for instance, for generating multimodal dialogue acts).

The research may (or may not) involve developing a pair of agents that have the ability to converse with each other, with the resulting behaviour mirroring, in relevant respects, the human behaviours as we find them in naturally-occurring dialogues.

Skills Required:

A degree in Computing (or equivalent), with experience in artificial intelligence, computational linguistics or natural language processing. A background in linguistics would also be suitable, if accompanied by a suitable computer skills.
