Argument mapping is used as a graphical method to display the structure of reasoning and argumentation. In the field of e-Learning argument maps are used as a mean to advance critical thinking. Nevertheless when the complexity of a reasoning problem rises the size and the complexity of the corresponding argument map expands accordingly making the latter hard to use. At the same time there are types of users that find text more comprehensive than an image.
In “Philoctopus” project argument maps have been used to represent philosophical thesis. In this project a novel approach has been used that combines argument maps and hypertext in an effort to help not only the visual type of user but also the propositional oriented users. Both, text and argument map, are displayed following simultaneously the browsing interactions of the user. In addition the argument map, developed in this project, can reduce dynamically the complexity of the graph. It can track any argument that the user focuses on and display only the specific parts of the argument tree needed for the visual representation of the focused argument.
