ABSTRACT

KQML (Knowledge Query Manipulation Language) is both a language and a protocol for establishing communication among multiagent systems. Researchers have been putting efforts to improve the existing structure of KQML. The latest version of KQML i.e. the KQML Improved not only supports existing features but it also extends the list of performatives and parameters along with a novel KQML based communication protocol. It also uniquely contributes security related performatives and hence limits the agents going destructive in a system. A comprehensive evaluation of KQML Improved with respect to available metrics as well as its comparison with its predecessor is being presented in the paper.
