Computational argumentation
Cards in this deck (8)
- 1What is the key difference between classical logics and nonmonotonic logics? – Why can we not just use classical logic to model defeasible reasoning?Nonmonotonic logics define consequence notion for defeasible reasoning
-Cant handle contradicting information?? - 2In argumentation, what is the difference between a rebutting attack and an undercutting attack?Undercutting is indirect in the sense of attacking the inference. Provides exception to the proposed rule that inference is based upon. Whereas rebutting is an attack on the conclusion itself
- 3Take an application of modus ponens in classical logic. Provide the knowledge base K, the ruleset R = Rs ÈRd and the argument A that captures this application.?
- 4Take the argumentation framework from slide 27 – Give the preferred and grounded extension(s)...
- 5Why does an “off the shelf” named entity recognition algorithm not work well on user generated content (e.g. crime reports submitted to the police)?Spelling mistakes, telegram styles, bad punctuation (human factor)
- 6What is an admissable set of arguments?– it is conflict-free: There are no arguments a and b in A,
such that a attacks b.
– the arguments in A are acceptable with respect to A: For
all arguments a in A, such that there is an argument b
that attacks a, there is an argument g in A that attacks
b. - 7Explain preferred extensionsAn admissible set of arguments is a preferred extension if it
is an admissible set that is maximal with respect to set
inclusion. - 8Explain grounded extensionsA conflict-free set of arguments is a stable extension if all
arguments that are not in the set are attacked by an
argument in the set.
