個人化網際網路電子購物代理人

Abstract

在網際網路的世界中，蘊藏著很多的資訊，幾乎所有的資訊皆可以在 網際網路中得到，但隨著資訊越來越多，我們遇到的問題不是找不到資訊 ，而是如何找到真正適合我們的資訊。在這樣的情況之下，我們必須發展 代理人程式協助我們於網際網路中找尋適合的資料並完成特定的工作。 電子商務亦隨著網際網路的發展而興起，處處可見網路購物、網路訂票等 的網站。隨著安全協定的制訂，網路購物將會成為一種新的趨勢。屆時如 何快速找尋產品的資訊，將變成一個重要的課題。 在這篇論文中，我 們提出了一個系統架構，在 Proxy 中發展個人化的代理人程式，在這種 架構之下，使用者不須改變原有使用瀏覽器的習慣，程式發展者也不須改 變原有的網際網路的協定。我們將以電子購物代理人為例討論這個系統架 構。 The rapid growth of Internet and World Wide Web (WWW) has produced a maze of documents, databases, and programs. Almost any information is available somewhere on the Net, but even expert researchers waste a lot of time searching for the right sources of information. Where to find desired information has become a big problem. What we need is a more personalized tool (agent) to help us travelling through the Web, searching information, buying or selling things and making orders. Because the SET (Secure Electronic Transactions) protocol ensures the security of Electronic Shopping, Electronic Shopping has become a new tide. How to find out information about products quickly will become another important issue. In this thesis, we propose a system architecture to develop agent applications based on proxy server. Under this architecture, neither do we need to change the standard protocols like HTTP and HTML, nor do we need to modify existing components such as web server and browsers. We implement an electronic shopping agent to illustrate the system architecture.
