PhD Thesis

Resolving different viewpoints of virtual agents can be addressed as a dialogical task in which arguments are exchanged. Thereby it is possible for each side to persuade the opponents by establishing a convincing argumentation structure. An Argumentative Dialogue System is a system that allows an agent to carry out argumentative task such as persuasion or negotiation against a human. Despite the strong theoretical grounding, implementations of these kind of systems are rather scarce since they have to overcome different obstacles.

In my thesis I address two important issues of such a system, namely the Natural Language Understanding (NLU) of arguments and the development of a flexible agent strategy.
