摘要： 针对传统服务发现技术不能利用历史行为经验问题，提出一种基于历史行为的服务发现技术，介绍新的服务发现模型——PASD模型，采用将模型封装成推荐服务的方法，验证该模型的有效性，仿真实验结果表明，基于PASD模型的系统能有效提高服务发现的效率，精确率可达80%左右。

Abstract: Aiming at the problem that traditional service discovery technique can not use past action experience, a novel service discovery technique based on past is proposed, and a new service discovery model called Past Action Service Discovery(PASD) is introduced. The validity of this model is proved by encapsuling it into recommendation service. Simulation experimental results show the system based on PASD model can promote efficiency of service discovery, and the accuracy is about 80%.

Key words: Web service discovery, service recommendation, Past Action Service Discovery(PASD) model
