本研究之目的在瞭解模糊搜尋與相關詞提示技術整合在圖書館線上公用目錄(OPAC)系統的應用情形，以提出線上檢索系統發展的改進建議，或作為其他圖書館、資料庫建置類似OPAC系統的參考。
研究方法主要採線上問卷調查與檢索記錄檔方析兩種方式。由檢索記錄檔的分析瞭解各檢索點被利用的比例、使用過程的變化、獲得零筆結果的原因。由線上問卷調查以探究使用者對檢索過程與結果的滿意度、使用者找到資料的情形、以及模糊搜尋、相關詞提示等功能對使用者找尋資料的幫助情形。
本研究的主要結論為：整合模糊搜尋與相關詞提示等功能的近似字串檢索系統，具有高使用率；多數使用者能運用最有利的檢索過程來進行查詢；使用者認為自動排序、相關詞提示、相關詞回饋等功能對瀏覽檢索結果、選擇檢索詞彙、進一步發現相關資料有所助益；多數使用者對檢索過程與結果感到滿意；低零筆結果的特性，能檢索出讓多數人滿意的結果。增進英文字的模糊搜尋、提供一次展現多筆詳細書目的功能、增加線上輔助說明為此系統仍須加強的部份。

The purpose of this research is to evaluation an OPAC (Online Public Access Catalog)system integrated with fuzzy search and term suggestion so as to propose suggestions for further system improvement and as references for other libraries in building their OPAC System.
The research approaches mainly rely on an on-line questionnaire and a search log. From the search log, one can understand the usage rate of each access point, the transition of access points during query session,the rate of 'zero results',and the reasons leading to zero results.
From the online questionnaire,one can find how satisfied are users with query processes and query results,the cases users find their search items, and the uxefulness of fuzzy search and term suggestion in helping users find their search items.
The main conclusions are as follows: 1.Both fuzzy search and term suggestion have high usage; 2. mostusers can use the best query strategy implicitly designed in the integrated system; 3. relevance ranking, term suggestion, and term relevance feedback are helpful for result browsing, query term selection, and term relevance feedback are helpful for result browsing,query term selection,and finding further related information, espectively; 4. most users are satisfied with query processes; 5. as to
query results, the low 'zero results' rate has satisfied most searchers. In spite of these findings, there are improvements to be made such as more powerful fuzzy search for English, enhancing the browsing function for viewing multiple detailed records in one page,and enhancing the on-line instructions.
