dc.description.abstract | 在本論文中, 我們提出一個以乏晰數之a-切割運算為基礎, 在分散式關聯 資料庫環境中將乏晰查詢轉換成精確查詢的方法。另外, 在一個分散式關 聯資料庫環境中, 我們亦提出一個方法以處理當其中有一資料庫失效時之 不完全資料估計之方法。根據本文所提之方法, 我們亦實作了一個系統以 在分散式關聯資料庫環境中將使用者之乏晰查詢轉換成精確之查詢。我們 所提出的方法可以讓使用者在分散式關聯資料庫環境中以更彈性的方式來 作資訊擷取。 In this thesis, we propose a fuzzy query translation method based on the a-cuts operations of fuzzy numbers to translate fuzzy queries into precise queries in the distributed relational databases environment. We also propose a method to estimate incomplete data when the relations stored in a failed server failed to access in thedistributed databases environment. Based on these proposed methods, we have implemented a system to translate fuzzy SQL queries to precise queries in the distributed databases environment. The proposed methods allow the users to deal with information retrieval in a more flexible manner in thedistributed relational databases environment. | zh_TW |
