Summary Report of the Second International Competition on Computational Models of Argumentation

We give an overview of the design and results of the Second International Competition on Computational Models of Argumentation (ICCMA-17). Following the first meeting in 2015, the competition evaluates the performance of submitted solvers on computational problems within abstract argumentation. In addition to the four original semantics, ICCMA-17 includes three additional prominent semantics. Moreover, a dedicated call for benchmarks allowed for the introduction of a sophisticated instance selection process.
