近年來，有愈來愈多的檢索系統增加互動性的功能，但是對於評估互動性 檢索系統仍然未有一套標準的典範。本文根據一項針對佛學數位圖書館所設計 的辭彙建議介面所進行的使用者研究提出報告。實驗介面將使用者檢索詞共現 的關鍵詞呈現給使用者，以作為使用者修改檢索詞彙之參考。實驗結果顯示， 不同的介面與不同的搜尋任務之間有互動的關係。本文也針對本研究在互動性 檢索系統評估方法上的意涵進行討論。

In recent years, more and more interactive features have been incorporated into information retrieval systems, but an evaluation paradigm for highly interactive systems has yet to emerge. This study reports the results of an experiment conducted to test the effectiveness and usefulness of a Term Suggestion Interface for a Buddhism study collection. Terms co-occurring with users1 original queries were extracted and presented to users in order to refine the search. The results suggest that the performance of the experimental interface is influenced by the number of potentially relevant records in the collection. The methodological implications for interactive information retrieval evaluation are also discussed.
