  Dialogue Systems are tools designed for various practical purposes concerning
human-machine interaction. These systems should be built on ethical foundations
because their behavior may heavily influence a user (think especially about
children). The primary objective of this paper is to present the architecture
and prototype implementation of a Multi Agent System (MAS) designed for ethical
monitoring and evaluation of a dialogue system. A prototype application, for
monitoring and evaluation of chatting agents' (human/artificial) ethical
behavior in an online customer service chat point w.r.t their
institution/company's codes of ethics and conduct, is developed and presented.
Future work and open issues with this research are discussed.
