SBIR Phase II: Semi-Automatically Constructing Wrappers to Access Internet-Based Information Sources

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，这些包装器可以从半结构化的网页中提取数据。 关键的创新是一个引导方法的包装生成，使包装以前的网站的经验可以自动重用，以尽量减少所需的工作，包装新的网站。 该技术将使几乎完全自动地创建数千个高度精确的包装器成为现实，为基于Web的信息集成创造了新的机会。该技术将使Fetch Technologies能够扩展我们目前的包装器生成技术，远远超出他现在的实用范围。 数以千计的互联网服务通过聚合和整合来自互联网资源的信息为其用户创造价值。 拟议的技术将使这些类型的服务从根本上更容易实现。 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。

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.
