Considering the completeness of subject extraction, this paper sorts the sentences with PageRank algorithm based on text theme divisions after reconstructing sentence relation map to every theme package. Then the sentence which has the maximum weight among all the texts is set to be the topics sentence. Experiments show that the topic sentence extraction algorithm has a good coverage of the full text.
