SBIR Phase I: Xtractica: A System for Extracting Coherent Data from Documents

这个小型企业创新研究(SBIR)第一阶段项目将调查设计和构建软件系统Xtratica的可行性。该软件系统将允许领域专家指定程序，将来自万维网、PDF文件和文本等各种文件来源的非结构化或部分结构化数据转换为结构化、连贯和易于使用的信息。Xtratica将由一套紧密集成的强大的句法和语义驱动的数据提取技术组成，这些技术从图形用户界面管理，以检索为人类可理解而创建的信息，并提取和推理这些信息，以创建能够支持自动决策和交易的知识。Xtratica的一个重要功能是，用户只需提供要提取的数据的示例，就可以快速创建提取程序。因此，它将使那些了解其应用领域但不一定接受过计算技术人员培训的用户能够将数据结构化为知识。第一阶段项目将制定Xtratica的操作规范，并通过制作其关键部件的原型来确定其可行性。然后，第二阶段将根据第一阶段的结果生产一个功能齐全的Xtratica系统。最后，第三阶段将向具有不同商业兴趣的客户提供Xtratica商业服务，包括内容聚合、电子采购、企业资源规划和供应链管理供应商。

This Small Business Innovation Research (SBIR) Phase I project will investigate the feasibility of designing and building a software system: Xtractica. This software system will allow domain experts to specify programs that transform unstructured or partially structured data from a variety of document sources, such as World Wide Web sites, PDF files and text into structured, coherent and readily usable information. Xtractica will consist of a set of tightly integrated powerful syntactic and semantics-driven data extraction technologies that are managed from a graphical user interface to retrieve information that was created for human understandability, and extract and reason about it to create knowledge that can support automated decision making and transactions. An important feature of Xtractica is that users can rapidly create extractors by simply supplying examples of the data to be extracted. Thus it will empower users who are knowledgeable about their application domains but are not necessarily trained as computing technologists, to structure data into knowledge.The Phase I project will develop the operational specifications of Xtractica and determine its feasibility by prototyping its critical components. Phase 2 will then produce a fully functional Xtractica system based on results from Phase I. Finally Phase 3 will make Xtractica commercially available to clients with diverse business interests including content aggregation, e-procurement, ERP and supply chain management vendors.
