【摘要】:提出了能夠綜合衡量搜索引擎工作性能的六個評測指標(biāo),選擇了當(dāng)今主流的三個搜索引擎:谷歌、雅虎和百度進(jìn)行評測,成功地在兩個大型的數(shù)據(jù)集上實(shí)現(xiàn)了整個自動評測系統(tǒng)。實(shí)驗(yàn)表明,谷歌工作性能最穩(wěn)定;雅虎返回的第一個結(jié)果最能滿足用戶的要求,但會受時間因素的影響;百度明顯地受關(guān)鍵字類別因素的影響。最后對中搜、狗、愛問進(jìn)行了評測。
[Abstract]:Put forward a comprehensive evaluation of the performance of the search engine six indicators, selected today's mainstream three search engines: Google, Yahoo and Baidu for evaluation, The whole automatic evaluation system is successfully implemented on two large data sets. Experiments show that Google's performance is the most stable; Yahoo's first return will best satisfy users' needs, but will be influenced by time factors; Baidu is significantly affected by keyword categories. Finally, the search, dog, love to ask the evaluation.
