Araucaria is an argument mapping software tool developed in 2001 by Chris Reed and Glenn Rowe, in the Argumentation Research Group at the School of Computing in the University of Dundee, Scotland. It is designed to visually represent arguments through diagrams that can be used for analysis and stored in Argument Markup Language (AML), based on XML. As a free software, it is available under the GNU General Public License and may be downloaded for free on the internet. ==How it works== The user interface is composed of a main window (diagramming), a schemes editor and the AraucariaDB online interface. When a text file is loaded into the program, the text is displayed in the left-hand panel of the main window. Highlighting portions of text before clicking on the right (larger) panel creates corresponding nodes at the bottom of that panel. Nodes can then be paired together by dragging one (which will be the premise) to the other (the conclusion). To each node may be attached a value such as the ownership of the proposition, or an evaluation specifying the degree of confidence placed in premise. Similarly, symbols can be added to the arrows to state the strength of the inference. In addition, the user may link arguments, supply missing premises (argument reconstruction) and use refutations. The diagram will always take the form of a tree structure in Araucaria. The user has the choice of translating the argument into standard diagram, Toulmin diagram or Wigmore diagram, Araucaria 3.1 being the first software to integrate the latter ontology and to address the translation issues between the different diagrams.〔Besnard, 2008, p357〕 While Araucaria helps identify the structure of an argument, it provides freedom of analysis resources. The scheme editor allows the user to create argumentation schemes, group them together and save them into a scheme set file. The scheme set is then applied to the diagram, entirely or in part. As an illustration, an argument scheme relying on symptoms could be applied to the following assertion: "The light has gone off. Therefore, the bulb must be broken", with critical questions intended to determine if the result could stem from another reason (such as "have all the lights in the flat gone off?"). The AraucariaDB Online Repository can be browsed to retrieve specific arguments to fit a diagram. Alternatively, an argument diagram, along with annotations, can be saved into the database. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Araucaria (software)」の詳細全文を読む スポンサード リンク
