The author shows that one can consider the time-dependent correlation functions of the $$XXO$$ Heisenberg chain as the generating functions of random walks on a one-dimensional lattice. The explicit forms of correlation functions on infinite, semi-infinite and finite lattices are obtained. The long time asymptotic behaviour of these functions is studied.
