Profiles of Dialogue for Repairing Faults in Arguments from Expert Opinion

Marcin Koszowy, Douglas Walton



Using the profiles of dialogue method we identify a species of ad verecundiam fallacy that works by forestalling of questioning in arguments from expert opinion. A profile of dialogue is a graph structure used to model a sequence of speech acts surrounding both the putting forward of an argument and the response to it at the next moves in a dialogue. The method is applied to a case of cross-examining a software engineer in a legal deposition in a case of intellectual property litigation.
