Abstract. In this paper we describe an application based on a general approach
towards modelling practical reasoning through defeasible argumentation. The
purpose of the paper is to show how the incorporation of an argumentation com-
ponent can add value to a collection of existing information agents. The example
application is a system for reasoning about the medical treatment of a patient.
An agent, called the Drama agent, orchestrates a number of information sources
to supply a set of arguments on the basis of which the decision regarding treat-
ment can be taken. We describe the general approach and its instantiation for this
application, and illustrate the operation of the system with a running example.
