This Small Business Innovation Research (SBIR) Phase II project focuses on developing technology for semi-automatically creating wrappers that extract data from semi-structured web pages. The key innovation is a bootstrapping method for wrapper generation, so that experience in wrapping previous sites can be automatically re-used to minimize the effort required to wrap new sites. The proposed technology will make it practical to create thousands of highly accurate wrappers almost completely automatically, creating new opportunities for web-based information integration.The proposed technology will enable Fetch Technologies to scale our current wrapper generation technology far beyond what his now practical. Thousands of Internet services create value for their users by aggregating and integrating information from Internet sources. The proposed technology will make these types of services radically simpler to implement. Applications include portal sites, comparison shopping services, auction sites, finance integration, and competitive intelligence-gathering services.

这个小型企业创新研究（SBIR）第二阶段项目的重点是开发半自动创建包装器的技术，从半结构化的网页中提取数据。关键的创新是包装器生成的自引导方法，因此包装以前站点的经验可以自动重用，以最小化包装新站点所需的工作。所提出的技术将使几乎完全自动创建数千个高度精确的包装成为现实，为基于web的信息集成创造了新的机会。提出的技术将使Fetch Technologies能够扩展我们当前的包装生成技术，远远超出目前的实际应用。成千上万的互联网服务通过聚合和整合来自互联网资源的信息为用户创造价值。所提出的技术将大大简化这些服务的实现。应用程序包括门户网站、比较购物服务、拍卖网站、金融集成和竞争情报收集服务。
