A convergent argument structure is a combination of multiple arguments,
each leading to the same conclusion. Often, but not always a convergent
argument structure provides a stronger support to the common conclusion
of its component arguments than each of these arguments would do in
isolation (see Prakken 2005, Bench-Capon and Prakken 2006). In Figure 3
you can see how two witness testimonies originate separate arguments
A and B which merge into the convergent argument C ,
which provides a stronger support to the common conclusion of A
and B .
