Abstract. We present a definition of entropy production rate
for classes of deterministic and stochastic dynamics. The point of
departure is a Gibbsian representation of the steady state
pathspace measure for which `the density' is determined with
respect to the timereversed process. The Gibbs formalism is used
as a unifying algorithm capable of incorporating basic properties
of entropy production in nonequilibrium systems. Our definition is
motivated by recent work on the GallavottiCohen (local)
fluctuation theorem and it is illustrated via a number of examples.
