| Abstract: | This paper introduces a multi-core parallel programs design method based on OpenMP,and used this method to implement the parallel reconstruction program of Web text mining based on Hidden Markov Model.The experiments show that the redesign of the multi-core parallel program compared to the original serial program greatly reduce the running time of the program,the overall program performance has been significantly improved. |
