... identify the current situation and respond accordingly in the environment whenever and wherever needed. However, it is quite challenging to detect and sense the more appropriate contextual information when various interactive devices communicate among themselves.

We propose theoretical as well as practical approaches to transform semantic knowledge into firstorder Horn-clause rules format which can be used by contextaware multi-agent systems to achieve their desired goals.
