  Over the last years, there has been a change of perspective concerning the
management of information systems, since they are no longer isolated and need
to communicate with others. However, from a semantic point of view, real
communication is difficult to achieve due to the heterogeneity of the systems.
We present a proposal which, considering information systems are represented by
software agents, provides a framework that favours a semantic communication
among them, overcoming the heterogeneity of their agent communication
languages. The main components of the framework are a suite of ontologies --
conceptualizing communication acts -- that will be used for generating the
communication conversion, and an Event Calculus interpretation of the
communications, which will be used for formalizing the notion of a satisfactory
conversion. Moreover, we present a motivating example in order to complete the
explanation of the whole picture.
