  Mediation is an important method in dispute resolution. We implement a case
based reasoning approach to mediation integrating analogical and commonsense
reasoning components that allow an artificial mediation agent to satisfy
requirements expected from a human mediator, in particular: utilizing
experience with cases in different domains; and structurally transforming the
set of issues for a better solution. We utilize a case structure based on
ontologies reflecting the perceptions of the parties in dispute. The analogical
reasoning component, employing the Structure Mapping Theory from psychology,
provides a flexibility to respond innovatively in unusual circumstances, in
contrast with conventional approaches confined into specialized problem
domains. We aim to build a mediation case base incorporating real world
instances ranging from interpersonal or intergroup disputes to international
conflicts.
