5. ### My Background - Cognitive Science & AI mind & brain

intelligent behaviour humans & machines Artiﬁcial Intelligence understand & build intelligent systems what makes an artiﬁcial system intelligent?

approach:
8. ### What makes an artiﬁcial system intelligent? AI - A modern

approach: think like a human
9. ### What makes an artiﬁcial system intelligent? AI - A modern

approach: think like a human think “rationally”
10. ### What makes an artiﬁcial system intelligent? AI - A modern

approach: think like a human think “rationally” act like a human
11. ### What makes an artiﬁcial system intelligent? AI - A modern

approach: think like a human think “rationally” act like a human act rationally

AI? HOW is it useful?

38. ### WHAT is Argumentation Theory? - Abstract Argumentation Yes - No

- Yes - No - Yes ...
39. ### WHAT is Argumentation Theory? - Abstract Argumentation Yes - No

40. ### WHAT is Argumentation Theory? - Abstract Argumentation Yes - No

- Yes - No - Yes ...
41. ### WHAT is Argumentation Theory? - Abstract Argumentation Yes - No

- Yes - No - Yes ... The sun is shining because it is summer. The sun is not shining because we’re in the UK. But 10 days a year the sun shines in the UK. The sun already shone 9 days this year, I doubt that today is the 10th day BBC forecasted sun for today.

80. ### HOW is Argumentation Theory useful? robot-robot interaction I’ll get the

ball because I’m closest. You won’t get the ball because you are too slow. Not if the opponent stops to think. Player 1 Player 2 Action: Player 1– get theball

82. ### HOW is Argumentation Theory useful? robot-human interaction You should do

your exercises now. But I want to watch TV. The doctor says you have to do them at exactly the same time every day. Robot Human Humanconvincedby robot

88. ### My research in Argumentation Theory compare Argumentation Frameworks: argument structure,

attacks, winning arguments
89. ### My research in Argumentation Theory compare Argumentation Frameworks: argument structure,

attacks, winning arguments combine Argumentation Theory with other reasoning methods: more powerful
90. ### My research in Argumentation Theory compare Argumentation Frameworks: argument structure,
