中文摘要：

面对分布式环境下涌现的海量Web服务选择问题，本文提出基于本体的企业信息集成框架，以此为基础研究如何加强语义对企业信息交互的支持．首先，提出支持多企业共建服务描述信息的分布式本体构建方法，其间给出业务信息的规范化模板，进而利用本体映射使多本体问相互理解；在此基础上提出一种依靠语义相似度进行服务发现的方法．该方法能够较好地支持由不同企业常用数据格式创建的分布式本体问的信息理解，实现对服务请求方和服务提供方的语义描述，从而提高服务匹配的查准率和查全率．

英文摘要：

For a large number of emerging web service selection problems in distributed environment, an ontology-based framework for the integration of enterprise information is proposed in this paper, and the problem how to enhance the supports to enterprises interoperability from semantic technologies is also investigated with this framwork. First, a distributed ontologies construction method supporting the description of the co-establishing service among multiple enterprises is presented. Meanwhile, the normalized templates for business information are given, and a multi-ontology mapping method is further employed to help multiple ontologies understand each other. Then, a semantic similarity based-method for service discovery is proposed. This method can improve the mutual understanding among distributed ontologies created with the data from different companies in their own common data formats, and realize the description of service semantically for both service requesters and service providers. All of the above efforts will improve the recall and the precision ratios of services matching.
