In this paper , the quantitative performances of the above models are compared using experiments . because the cosine measure is not able to reflect the structural similarity between documents , a new retrieval model based on texttiling is proposed in the paper 本文對這些已知模型在相似搜索問題上的性能做出了實驗對比,并且針對余弦模型無法考慮文檔結(jié)構(gòu)相似性的缺點,提出了基于texttiling技術(shù)的相似檢索模型,該模型考慮了文檔的子主題結(jié)構(gòu)信息。
