中文摘要：

文章提出的SophiNode模型，在现有P2P服务发现技术的基础上，模拟人类的交流过程，让每个节点都具有“经验”和“直觉”，在分布式电子商务环境中，利用成熟节点快速、正确地发现商务服务。节点通过自身的服务信息库及对每个邻居节点的成熟度指标进行评价，从而选择合适的成熟节点。实验结果表明该模型行之有效，能够较大地提高服务发现的效率。同时较好地解决了扩展性、复杂性等问题。

英文摘要：

Decentralized E-Commerce is one of the application areas of P2P infrastructure.And service discovery as to decentralized E-Commerce is just like content location as to file sharing.We put forward an efficient service discovery system of decentralized E-Commerce,and name it SophiNode.SophiNode tries to simulate the communication process of human being,and adds on each node＇s ＂experience＂ and ＂intuition＂ ,so that it can be smart enough to find the right shortcut when forwarding queries.A particular organization of Service Information Base is designed to avoid scaling problems as well as improve search efficiency.A set of Node Sophistication Metrics along with the concept of Sophisticated Node is adopted,so that each node could tell which neighbor is relatively more powerful and sophisticated.In the end,we present the simulation and analyze the results.
