An argument map is a visual representation of an argument using boxes and arrows to show the structure, including main claims, premises, objections, and rebuttals. Argument maps are used to support deliberation over complex problems and can help analyze pros and cons. They have applications in education, academics, and business, and dating back to the 1800s. Standards like the Argument Interchange Format and Legal Knowledge Interchange Format have also been developed to exchange argument resources between research groups.
