Abstract Sequential pattern mining is an important data mining research topic. In this paper the global partial order algorithm is firstly analyzed. Then, a heuristic algorithm is proposed for improving the process of global partial order construction. By using the local sequence pattern information, the problem of constructing the partial order model with high mathematical complexity can be avoided, and accurate results can be obtained. Finally, the efficiency and accuracy of the proposed method are validated by the experimental results on synthetic and real dataset.
