The tool is a web version of the Carneades argumentation system extended with support for comparing policy alternatives in deliberative democracy application scenarios. The tool can be also be used as a legal expert system shell, for example in applications for helping citizens to assess their rights to social benefits, in much the same way as some commercial rule-based systems, but goes further towards realizing the vision of isomorphic modeling by being based on the state-of-the-art in Artificial Intelligence and Law and Computational Models of Argument fields.enartificial intelligencelawargumentation technology004conference paper
