doctorate | linguistic signalling games in improvised theatre
supervisors: Andrea C. Schalley (KU), Claire Kennedy (GU), Anton Benz (ZAS)

My thesis offers a game theoretic model of language use in improvised theatre. The model views actors as rational agents who use linguistic strategies to yield the greatest possible utility. Executing an improvised performance requires planning of the plot’s trajectory, which necessarily take place during the performance. So, actors must produce utterances that signal this planning information while concealing it from the audience, for such information damages the performance’s verisimilitude. The model set out in this thesis is novel for a game theoretic study insofar as its primary purpose is to be a descriptive model of a particular genre of speech. It is based on a dataset of two hours of improvised performance. I make four major amendments to the standard game theoretic model: (i) a formal, structured model of discourse; (ii) a means of modelling repeated interactions between the same agents; (iii) complex conditions of epistemic access to background information; and (iv) a model of hiding information in natural language utterances.

ausEn and forced migration | an object-oriented semantics
collaborators: Andrea C. Schalley (KU)

Forced migration is a topic which attracts much attention from the Australian public, especially in political discourse. Three terms that are used frequently in such discussions are refugee, asylum seeker, and boat people. This project looks at the semantics of these terms, using an object-oriented model based on UML, first proposed by Schalley (2004). The findings are based on a large sample of text data of online comments on the first season (2011) of the SBS television programme Go Back To Where You Came From.
