The vector space model is used to evaluate the similarity of two sentences for the hierarchical clustering algorithm. After clustering, we choose representative labels and comparative sentence pair for every cluster. According representative labels, the clusters which have the same labels will be grouped as a new concept hierarchy.資料探勘資訊檢索句子分群自動摘要Data MiningInformation RetrievalSentence ClusteringAutomatic Summarization
