  5. Experiments are performed and results show : 1 the popular retrieval models the okapi s bm25 model and the smart s vector space model with length normalization do not perform well for document similarity search ; 2 the proposed model based on texttiling is effective and outperforms other models, including the cosine measure ; 3 the methods for the three components in the proposed model are validated to be appropriately employed

    我們通過實驗驗證了以下三點: 1 trec中的常用信息檢索模型不能很好地解決文檔相似搜索2我們提出的基於texttiling技術的模型是有效的,性能優于其他模型3我們提出的模型中所採用的方法是有效的,包括利用texttiling技術進行文本子主題分割,利用餘弦公式來計算文本塊之間的相似度,以及利用最優匹配方法來求解文檔之間的總體相似度。
  6. Document similarity search is to find documents similar to a given query document and return a ranked list of similar documents to users, which is widely used in many text and web systems, such as digital library, search engine, etc. traditional retrieval models, including the okapi s bm25 model and the smart s vector space model with length normalization, could handle this problem to some extent by taking the query document as a long query

    文檔相似搜索指從文檔集中檢索與給定查詢文檔相似的文檔。對于給定的查詢文檔,我們期望文檔相似搜索系統能夠返回一個按相似度排序的相似文檔列表。文檔相似搜索技術已經被廣泛應用到電子圖書館,搜索引擎等系統中,例如citeseer . ist科學文獻數字圖書館的相似文獻推薦功能, google的相似網頁查詢功能等。
