dc.description.abstract本論文對關聯式資料庫系統提出一個以α - 切割為基礎的乏晰查詢 語言轉換的新方法,這個方法允許查詢語言的條件部份可以用語義詞 ( 乏晰數 ) 來表示,它強調對不熟悉系統的使用者的親和性和彈性。根據 本論文中所提的乏晰查詢語言轉換方法,我們亦實作了一個乏晰查詢語言 轉換器,以將使用者輸入的乏晰查詢轉換成一般關聯式資料庫系統所用的 確定 ( 非乏晰 ) 查詢。因為本論文中所提的方法可以讓使用者作直觀地 查詢,而且也可以讓使用者在作乏晰查詢語言轉換時選擇適當的臨界值以 作乏晰查詢,故本論文中所提的方法將可以讓現有的關聯式資料庫系統更 具親和性及更具有彈性。 A new method for fuzzy query translation based on the α -cuts operationsof fuzzy numbers is presented in this thesis. The proposed method allows theretrieval conditions of SQL queries to be described by fuzzy terms representedby fuzzy numbers. It emphasizes friendness and flexibility for theinexperienced users. We have implemented a fuzzy query translator to translateuser's fuzzy queries into precise queries for relational database systems.Because the proposed method allows the us er to construct his fuzzy queriesintuitively and to choose different retrieval threshold values for fuzzy querytranslation, the existing relational database systems will be more friendlyand more flexible to the users.zh_TW
