Abstract: As a special kind of reusable software resources on the Internet, Web Services have received great attention. However, general Web search engine cannot well support the discovery of Web Services, which makes developers have to spend a lot of efforts in order to acquire their desired Web Services. For this reason, this paper proposes an approach for harvesting Web Services from the Internet by leveraging general search engine and specific Web services portals. In addition, it also proposes an approach to extract descriptions for Web Services from their related Web pages on the Internet. Based on the harvested data, it conducts a statistics analysis on the status of Web Services on the Internet.

摘要： Web Services作为一种部署在Internet上的新型的可复用软件资源, 得到广泛的重视和应用。但是,现有通用搜索引擎并不能很好地支持Web Services的发现, 这使得软件开发人员需要花费很大的代价寻找合适的Web Services。鉴于此, 提出了一种基于Internet的Web Services获取方法, 采用通用搜索引擎和特定Web Services信息发布网站相结合的方法, 从Internet上收集Web Services, 并从Web Services的相关网页中抽取相关描述信息。利用收集到的Web Services数据, 对当前互联网上的Web Services现状进行了统计分析。这些统计结果一定程度上反映了Web Services的发展现状。
