摘要


由於資訊供應者所提供的資訊和服務隨著時間倍增﹐因此使用者在網路 上獲取資訊和服務由以往完全沒有或資訊量少且容易辨認取得的情形﹐ 演變到今日難以在數以萬計的資料中﹐擷取真正所需資料的窘境。如何 讓使用者在操作網路服務系統時,能以最簡單的操作,獲得較適切的資 訊服務,一直是存在於使用者和資訊供應者兩者間的問題。本篇論文提 出一種在WWW環境中線上自我導向學習使用者偏好的方法以及一個以 Intelligent Agent Technology為基礎的適性化個人資訊服務架構,藉 此能夠易於建構一個便捷的適性化個人資訊服務系統。我們的想法是: 不直接去幫使用者決定哪一篇文章或資訊是他所喜好,而是由使用者挑 選一個資訊主題,系統再提供符合使用者偏好之子主題,如此繼續下去 ,便可以提供符合使用者偏好的資訊,讓使用者能以簡單的操作介面參 與取回資訊的過程,應該就能夠較正確地反應及學習使用者偏好,我們 的重點是:要去學習使用者感興趣的主題,並透過一個適性化的使用者 界面,將那些使用者感興趣的主題顯示在最顯眼的位置,以方便使用者 點選及操作。使用者除了可以很容易地在網路上正確地獲取各種資訊, 並且得到滿意的資訊服務外,對於避免網路資源浪費及降低網路擁塞也 有正面的助益。

Since the Information Supplier has to offer rapidly growing amount of information and services, users encounter difficulties in finding the desired data in the flood of information. How to let users having a satisfied information service and an easy-operating information system has become the problem between users and Information Supplier. This thesis proposed a self-directed learning method for on-line learning User Preferences based on WWW and an adaptive personality information service(APIS) architecture based on Intelligent Agent Technology to construct an APIS system easily. Our main idea is that without offering users preferred documents or information directly, we let them making their own choice on an information topic; the service system will then offering the sub topic repeatedly which matching the user preferences. The key-point of the learning method is to study the user-interested information topics, showing on the most obvious position on the screen in order for easy-clicking through adaptive personality interface. In addition to user-satisfied information services, the proposed learning method has implicit benefits that can avoid wasting network resources and reducing network traffic.
