摘要： 服务自动发现的实现中的核心问题是服务的自动匹配和定位。该文提出的解决方案是采用owl-s profile来提供发布服务属性和功能描述的广告，构建基于ontology的服务搜索引擎，采取服务参数匹配和输入参数匹配的分级匹配方式，实现了基于概念推理的服务自动定位。介绍了基于该方法开发出的一个电子商务系统原型，描述了它的系统架构和实现机制，分析了该解决方案的可行性。

Abstract: The main point of automatic service discovery is locating services automatically. This paper introduces a solution to solve this problem. It uses owl-s profiles to publish service advertisement which describe service properties and functions, build a service match engine based on ontology, take a multi-step matchmaking method to implement automatic service discovery. It also describes the architecture and implementation of an e-commerce system prototype based on this solution, and analyses the feasibility of this solution.

Key words: Semantic Web service, Ontology, Automatic service discovery, OWL-S
