Abstract: To mine accurately process patterns and improve anti-noise ability, a new method of process pattern mining based on probability statistics of adjacent event was proposed to generate automatically process patterns mining based on rules through only once traversing logs and simply calculating matrix. Comparing with α-algorithm and heuristic algorithm, the results from analyzing mining performance and verifying experiment show that it can mine pattern structures of sequence, choice, paralleling, recursion and short loop, and has advantages of low complexity and good anti-noise ability.
