Abstract

Classically an argument terminates when the parties involved agree to the truth of a proposition known as the claim. On Gilbert's model of multi-model argumentation this approach is inadequate since a "claim" as such does not exist except as a logical artifact or abbreviation. In its place one must consider a "position," an object that contains within it much more information than can be found in an individual statement. While this adds a greater amount of complexity, it has the advantage of more ac curately describing the workings of marketplace argumentation.
