TSP: Mining Top-K Closed Sequential Patterns

  title={TSP: Mining Top-K Closed Sequential Patterns},
  author={Petre Tzvetkov and Xifeng Yan and Jiawei Han},
Sequential pattern mining has been studied extensively in data mining community. Most previous studies require the specification of a minimum support threshold to perform the mining. However, it is difficult for users to provide an appropriate threshold in practice. To overcome this difficulty, we propose an alternative task: mining topfrequent closed sequential patterns of length no less than , where is the desired number of closed sequential patterns to be mined, and is the minimum length of… CONTINUE READING
