Between Pro/Con-Lists and Argument Graphs Finding the Right Level of Complexity in Argumentation Representation

Pro/Con-lists are one of the most common ways of summarising the main points of debates surrounding practical decisions. However, their simplicity has attracted criticism and argument graphs have been proposed as an alternative. Since graphs can easily become very complex, they tend to be difficult to use in everyday life. Our proposal, the Concern-Oriented REasoning (CORE) table, lies in-between the two. It improves on the drawbacks of pro/con-lists without having to go to graph-level complexity. We start by identifying and organising the main reasons for and against an action into a pro/con-list. We then add structure to the CORE-table by organising the main reasons according to their subject matter. Additional arguments surrounding the main reasons are then placed in designated spots based on their function.
