Design and Implementation of Access Mechanism and Data Mining for a Personalized Education System

本計畫中所規劃的網路教學系統包括 了同步與非同步的教學模式，主體架構建 立於Web 之上，而其主要的研究課題有 三：一是影音文件同步及互動功能的研 發；二是Web 上多媒體教學資料之存取與 傳輸架構：三為資料收集倉儲技術之研發 及個人化使用機制之研究。首先，我們研 發技術更有效率地將學習者端的Web 瀏覽 器和教學資料庫系統連接。在此，我們建 構新的多媒體資料庫系統，以有效的存放 各種多媒體的教學資料。其次，我們研發 搜集使用者行為之機制並作資訊勘測 （data mining）以瞭解學生之操作模式並 據以作系統改進。最後，我們改善此一教 學系統的介面，以提供學習者更多的互動 功能。應用此計畫所研發之技術，可以協 助推動多媒體輔助教學，使網路系統發揮 更具建設性的功能。隨著網際網路的普 及，網路教學已漸被廣泛地使用，我們深 信此計畫之執行對網路教學可提供同時深 具學理與實用價值的成果。This project is under the integrated project “An Adaptive Networked Educational System: toward Ubiquituous Personalized Learning,” and aims at using the WWW as an interface to provide access mechanism and data mining for a personalized networked education system. The system is composed by both asynchronous and synchorous distance education subsystems. Our primary goal includes (1) eatablishing an efficient Web access mechanism, (2) providing proper personalized education systems, and (3) studying multimedia data synchronization. More specifically, we first devise techniques to allow users to efficiently access data from a networked education system through the Web interface. Next, we develop and implement data mining algorithms to capture the user behavior. Finally, we shall utilize the related technologies to enhance the efficiency of multimedia communication as well as to increase user friendiness by allowing more interactive functions. In view of the increasing importance of Internet, network education systems are expected to become popular rapidly, and we believe this project should deliver very timely results which are of both theoretical and practical importance
