We want to consider a dialog situation between a system and a heterogeneous
group of dialog partners. Our problem is to find adequate representational
means for describing the beliefs, goals, and plans of each agent. We assume
that we can provide a sufficiently detailed description of the knowledge base
of the system, but we don't have complete descriptions of the knowledge bases
of all other participating agents.

In this paper I propose an approach which is in line with the {\em modal logic
approach\/} of Allgayer, Ohlbach, and Reddig (1992). The basic idea is to
enhance a decidable fragment of first-order logic with modal operators for
modeling the notions of belief, knowledge, and desires. To provide the initial
knowledge base for agents, we support mutual and group beliefs, knowledge, and
desires.
