Commonsense reasoning and probabilities

Principles of defeasible reasoning cannot be purely founded on probability theory (PT): Not all defeasibility is probabilistic

Frame axioms, norms, goals, ... PT produces mere probabilities

But probability theory can inform NML

Argumentation visualisation software

Support for drafting and visualising argumentation structuring argumentative texts

Useful for: Teaching argumentation

D causes SNot-S is observedSo D is not the case

Topics for final Msc project (1)

Theoretical research on inference Defeasible vs. probabilistic reasoning

E.g. add probabilistic strengths to ASPIC+ A theory of preferences in argumentation Optimising argument games by utilising the

structure of arguments Dynamics in structured argumentation

Theoretical research on dialogue Dialogue protocols Agent strategies and personalities Argumentation in negotiation or deliberation Relation with game theory …
