「全國檔案目錄查詢網」係為使用者查詢政府檔案資訊的重要管道，惟該查詢網在設計開發階段，並未進行使用者之測試作業，了解使用者之使用意見，且該查詢網自正式開放以來，其使用人次統計數據的成長率並無明顯變化，故本文旨在以訪談方式深入了解使用者使用全國檔案目錄查詢網的原因、經驗、評價及建議等，並據以評估系統是否需要改善，以及可能的改善空間。

面對網路資源檢索結果往往過多的問題，如何將當中最相關的資訊優先排序在最前面，讓使用者優先看到，以節省其瀏覽所有檢索結果的時間，是目前系統開發者選擇相關排序（Relevance ranking）作為檢索結果排序的原因。目前大部分的資訊檢索系統係以相似性而非相關性作為檢索結果排序基礎，但使用者係判斷檢索結果相關與否之唯一裁判者，為此，相關排序的發展也開始將使用者的相關判斷及資訊使用行為作為改善相關排序效能之努力方向，希望能針對使用者的不同需求提供更個人化的資訊服務。

The retrieval results of a web search are usually very large. Therefore, the information retrieval system usually uses the relevance ranking to ranking retrieval results, providing users a saving-time way to look through the searching results and obtain the most relevant documents. Currently, most information retrieval systems use similarity instead of relevance to rank the searching results. However, the end-user is the one to determine the relevance of retrieval results, so many researchers consider the user’s relevance requirement and information behavior are the way to improve the effectives of relevance ranking. The objective of relevance ranking is to provide personalized information service for users.
