Argumentation Systems
Argumentation Systems
Argumentation systems aim to reflect how human argumentation uses conflicting information to construct and analyse arguments. So argumentaiton systems involve identifying arguments and counterarguments relevant to an issue (e.g. What are the pros and cons for the safety of mobile phones for children?). Argumentation systems may also involve weighing, comparing, or evaluating arguments (e.g. What sense can we make of the arguments concerning mobile phones for children?) and they may involve drawing conclusions (e.g. A parent answering the question ``Are mobile phones safe for my children?"). In addition, argumentation system may involve convincing an audience (e.g. A politician making the case that mobile phones should be banned for children because the risk of radiation damage is too great). Logic-based formalizations of argumentation have been extensively studied, and some basic principles have been established. These formalizations assume a set of formulae and then exhaustively lay out arguments and counterarguments, where a counterargument either rebuts (i.e. negates the claim of the argument) or undercuts (i.e. negates the support of the argument). Recent developments of argumentation systems includes taking rhetorical issues into account.
