　　隨著網際網路的普及，各技術發展之進步與產業結構的改變，企業經營的環境面臨了全球性的挑戰。如何做到整體資源的有效利用和快速回應，將成為保有企業競爭優勢的主要關鍵。
　　在本篇論文中，使用UN/CEFACT (United Nations Centre for Trade Facilitation and Electronic Business, 聯合國貿易促進及電子商務中心) 和OASIS (Organization for the Advancement of Structured Information Standards, 美國「結構化資訊標準推動組織」)所共同制定的ebXML(Electronic Business using eXtensible Markup Language)標準，其目標是利用以XML為基礎之相關規格和應用從事商業行為，建構一全球互通性之電子交易基礎架構，以降低中小企業跨入網際網路電子商務的門檻和障礙。
　　我們將實作以代理人（Agent）為基礎之自動化企業間商務技術交談內容協商，本研究所侷限的範圍在ebXML架構中，描述交易夥伴商業能力的CPP（Collaboration Protocol Profile）文件，透過代理人之技術，自動協商而產生CPA（Collaboration Protocol Agreement）。整個系統架構的核心，即為以LPA WIN-PROLOG所建構之代理人。代理人主要的工作是將雙方的CPP文件內容做比對，並加以分析，再針對雙方文件相異之處做評估，提供理想的建議。
　　期望藉由此系統所提供的機制，使資訊傳遞的模式獲得一致，並以代理人作為意見溝通的工具，以減少企業在營運時所需要的成本，和加快資訊處理的時間。

With the internet develop, the technique has made progress prosperously and industrial structure has made substantial change. It is important that how to use resource effectively and response quickly for enterprise competition.
In the thesis, we follow the Electronic Business XML (ebXML) specification that driven by he United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) and the Organization for the Advancement of Structured Information Standards (OASIS). The vision of ebXML is to establish framework for global electronic transaction. And it will reduce an obstacle to small and medium enterprise use electronic commerce.
I will implement agent-based negotiation of technical automatic agreement in electronic business. The research is focus on ebXML framework. The CPP document describes ability of business transaction. It will negotiate automatically for create CPA through the technical of agent. The heart of system architecture, negotiation agent, will be constructed by LPA Win-Prolog. The primary functions of agent are match and analysis the CPPs' content. For the difference between two parties' document, give it appropriate evaluation and ideal suggestion.
I hope that through the mechanism system provides will agree with the type of information transmission. For business, this will not only reduce the management costs but also speed up the information processing time.
