Speech Acts in Artificial Intelligence

One goal of strong artificial intelligence (AI) is to programme a computer that is indistinguishable (according to Alan Turing) from a human in its dialogue behaviour. It is in linguistic interaction that we decide whether we regard a device as intelligent. However, there is a deficit in research and society: rarely is a conception of speech acts seen as a decisive factor for “intelligence”. The research project wants to find out (i) which types of speech acts as well as (ii) which rules associated with them can serve as a basis for an intelligent dialogue system. The focus is on cognition-oriented speech acts: In order to gain and use cognition, we make assumptions, attract what is already known to be true; we assert, deny, doubt, define, abstain from judgement, infer, question, state, postulate and assume. Some of these speech acts are already well-regulated in formal logical frameworks. But how do we add to them and combine them in a coherent way? And what kind of intelligence then results?
