  6. However, their current status is still far from user ' s satisfaction. lt includes : ( 1 ) the content that search engine returns is a enormous flat bill ( information overloading question ) ; ( 2 ) the items return with search engine are not the content that user requisite in deed ( low precision question ) this paper presents a fuzzy ( soft ) clustering algorithm htsc ( hyperlink - text based soft clustering ) using a mixed similarity metric of document content and inter - document hyperlinks, for clustering web search results from a search engine in order to help users find relevant web information more easily

    這主要表現為： （ 1 ）搜索引擎返回的結果是一個龐大的平坦結構的資源清單（即信息負載問題） ； （ 2 ）搜索結果中的信息項並非都是用戶真正需要的信息資源（即低精度問題） ；論文提出了一種基於文檔文本內容和文檔間超鏈信息的混合相似度的模糊（軟）聚類演算法htsc 。該演算法可對搜索引擎返回的結果進行模糊聚類，以方便用戶從中找到真正需要的信息。
