Involvement in Software Demonstrators:

ABDA (Argument-Based Discussion using ASPIC-)
ABDA (Argument-Based Discussion using ASPIC-) is an implementation of the Grounded Discussion Game in combination with ASPIC-. The demonstrator is written in Python and runs from the command line. An updated version can be found on GitHub.
DISCO (DIScussion COmputation)
DISCO (DIScussion COmputation) is an online implementation of the Grounded Discussion Game and the Preferred Discussion Game. The demonstrator is based entirely on Javascript, meaning that all computation is performed at client side.

Some of the older demonstrators are available on my publications page.
