電子目錄主要是提供產品資訊搜尋，與產品目錄瀏覽功能。面對網際網路上越來越多的網路商店，消費者並不容易有效率的取得所需要的產品資訊。透過電子中介者提供的資訊過濾、商品搜尋、電子目錄等功能，可以幫助消費者有效率的瀏覽、搜尋、與交易產品。
由於可延伸性標示語言(XML)可有效的提供資料的自動處理與互通整合性，其在電子商務應用上愈趨重要。本研究應用XML的特性建構一個三層式的資料描述架構，以提供資料發掘、資料轉換以及各種產品種類的屬性資訊。
本研究的目的是要發展一個以XML為基礎的個人化電子目錄。所提出的系統提供個人化的設定，與依據商品屬性之結構化查詢。此系統架構由數個軟體代理程式所構成。透過這些軟體代理程式彼此溝通合作，在眾多虛擬商店組合而成的異質環境中有效的搜尋各種產品資訊，使消費者可以方便的瀏覽與查詢網路上的商品資訊。

Electronic catalogs provide the services of product search and catalog browsing. With the growth of virtual stores and product information on the Internet, it is not easy to get desired product information efficiently. The electronic broker can help customers to navigate, search, and transact products by the functions of information filtering, product searching and electronic catalog.
With effective interoperability, XML is emerging as an important meta-language in electronic commerce. Our work applies the characteristics of XML to construct a three-level metadata architecture. The metadata is able to facilitate resource-discovery and format translation, and to provide information about attributes of a product category.
The objective of this work is to develop an XML based personalized electronic catalog. It provides personalized user profile, and structured query based on the attributes of each product. The proposed system architecture is composed of multiple agents. Each agent communicates and cooperates with each other to efficiently search heterogeneous product information from various virtual stores on the Internet. This system can make customers browse and search products on the Internet more conveniently.
