Based on the previous study, half of queries issued into search engines have no follow-up click-through data. This indicates users usually are not satisfied with the performance of current search engines. To address this issue, this paper proposed a query refinement mechanism RebaCQ, which can assist users to obtain satisfactory pages as soon as possible. RebaCQ utilizes the user knowledge extracted from previous consecutive queries and provide a refined result set to users. Our experimental results indicate the significantly increase in the result accuracy after query refinement.http://140.113.39.130/cgi-bin/gs/hugsweb.cgi

根據以往的研究，有半數以上送進搜尋引擎的查詢字串沒有點選任何網頁。這代表仍然有多數使用者對於目前的搜尋引擎所回傳的結果不滿意。針對這個問題，我們提出了一個修正查詢字串的機制，RebaCQ，他可以盡快的幫助使用者得到令他們滿意的結果。RebaCQ是利用使用者之前所下的連續查詢字串得到資訊，進而提供修正過的結果給使用者。我的們實驗結果指出，經過RebaCQ機制之後，結果能有大幅度的改善。
