摘　　要：Web包装器是根据特定的抽取规则从特定的Web数据源执行数据抽取程序,设计Web包装器是Web信息抽取和集成的关键技术。详细阐述了一种基于预定义模式的Web包装器的设计与实现过程,并选取了几个出版社的新书发布Web页面进行了数据抽取验证和抽取结果分析,取得了较好的效果。充分体现了此Web包装器的可行性、高效性及可维护性,能够应用在基于Wrapper/Mediator方法的Web数据集成。Web Wrapper extracts the data from the given Web source, according to the corresponding extraction rules of thorn, design is a key technology for Web information extraction and integration. Describes the design and implementation of a kind of the Web Wrapper which hescd on pre - defined schema. Then validates the data extraction from the new books information Web pages of some publishing companies and analyses the extraction results with this kind of Web Wrapper. Find it can accurately extract the data from the Web source.So can conclude that this kind of Web Wrapper which proposed in this paper is feasible, efficient and maintainable. It will be applied for Web data integration based on Wrapper/Mediator.
