Arguing about Arguing is a series of videos that outlines trends in case notation literature, over the last 20 or more years, that seem to be overturning the position that Goal Oriented Requirements Engineering notations, such as i* and Goal Requirements Language (GRL) could not be used as assurance reasoning - during the Act of Design.

Part 4 picks up from where Part 3 left off.   Part 3 having left us with the idea that case based notations are a subset of the semantics of Goal Oriented Requirements Engineering notations.  So, its difficult to get to the position that case notations are different from or superior to Goal Oriented Requirements Engineering notations, for the purpose of capturing reasoning.   Whether assurance reasoning is a special form of reasoning, or just a mode of use, is therefore an important question.

Part 4 closes with the crux of the problem for case notations, being whether it made sense or will ever make sense trying to argue dialogically with a monovalent monological semantic network.

In the middle, Part 4 then runs through what low versus higher epistemic standards might look like when using an acyclic graph.   It looks at the brittleness of case notations on the basis that they are designed only to make claims meeting low epistemic standards.   The evidence is the debate in the literature about rebuttal, defeaters and defeasible reasoning.   Concepts that were not captured in the design of case notations originally.  Concepts the absence of which case based reasoners continue to lament.




As always, the basis of this position of mine is at:
