【摘要】:將目的搜索引擎返回的結(jié)果經(jīng)分詞處理并提取主要關(guān)鍵詞后,采用關(guān)聯(lián)規(guī)則建立關(guān)聯(lián)詞矩陣,并利用FCM(Fuzzy C-Means,模糊C均值聚類)對結(jié)果進(jìn)行聚類,且通過聚類有效性函數(shù)FP(U,c)判斷最佳聚類結(jié)果,最終按照相關(guān)度大小順序?qū)⒔Y(jié)果返回。通過與K-means(K均值聚類)算法的實(shí)驗(yàn)對比發(fā)現(xiàn),以上方法能有效地保證運(yùn)行效率與聚類個(gè)數(shù)的有效性,且提高了相關(guān)結(jié)果的排序位置,因此更能滿足用戶的需求。
