Introduction, Rules, Argumentation and Methodologies Flashcards
When is a agent based solution fitting?
Agents are a metaphor for the problem, environment is appropriate (open, dynamic, uncertain), legacy software, data/control is distributed.
What is the goal of Agent-oriented analysis and design techniques?
Goal is to assist in understanding a system, to assist in designing a system
Abstract argument system
set of arguments with attack relations
Dung’s basic principle of argument acceptebility
The one who has the last word laughs the best
When is a set admissible?
If it is conflict-free and all arguments in A are acceptable with respect to A?
When is a set conflict free?
No argument in the set attack each other
Preferred extension
maximum admissible set
Stable extension
conflict free, if all agents that are not in set are attacked by the set
Three steps to find the grounded extension:
1) Green the ones not attacked or all attackers are red
2) Red the ones which are attacked by green ones
3) Go to 1 if something changed, otherwise stop
Ad hominem fallacy + two extensions of it
attack opponent instead of argument made,
Define argument system
conduct a critical discussion in which hypotheses can be constructed, tested and evaluated on the basis of reasonable arguments.
Define knowledge technology
system with expert knowledge and ability to use it
Define agent technology
individual agents that interact
In what do the definitions of an agent differ between Russell&Norvig Vs. Wooldridge?
Russel&Norvig defined an agent as anything with sensors and actuators to react.
Wooldridge: computer system capable of autonomous decisions toward goal
What is the difference between forward and backward chaining?
Backwards uses rules to go from goal to subgoals to facts, while forward goes from facts to goals.
