Collaborative Research: TANGO: Table Analysis for Semiautomatic Generation of Ontologies

这个合作项目“TANGO”利用了杨百翰大学（IIS-0414644，PI：大卫恩布利）和伦斯勒理工学院（IIS 0414854，PI：乔治纳吉）研究团队的优势。TANGO是一个框架，用于组织出现在独立生成的网页中的特定领域的事实数据。开发了算法和软件，用于提取和解释个别清单和表格，并将其与提供部分重叠信息的其他表格的内容结合起来。输入页面可以是HTML、PDF、XML或扫描的文档图像文件。该系统的输出是一个本体，提供了该领域的概念框架。本体随着具有附加相关数据的网页被收获和处理而演变。构建本体目前是一个劳动和技能密集型的过程。当信息存在于描述域的列表和表格中时，TANGO框架自动化了域的大部分本体构建任务。这个项目的成果为语义网搭建了垫脚石，而本体是语义网的核心组成部分。因此，这个项目将产生影响的语义Web，谁的自动化软件代理在这个项目中开发的协助下，可以完成基于信息的任务，研究，学术，规划，设计，教育和娱乐的用户。这种跨学科和跨大学的奋进介绍研究生和本科生的前沿研究。在项目网站（http：//www.example.com）上可以找到开发的工具（包括源程序）、原始和标准化形式的表格语料库、收集的测试数据和技术报告。www.tango.byu.edu

This collaborative project "TANGO" is leveraging strengths of research teams at Brigham Young University (IIS-0414644, PI: David Embley) and Rensselaer Polytechnic Institute (IIS 0414854, PI: George Nagy). TANGO is a framework for organizing domain-specific factual data appearing in independently generated web pages. Algorithms and software are developed for extracting and interpreting individual lists and tables and integrating them with the contents of other tables that present partially overlapping information. The input pages may be HTML, PDF, PostScript, or scanned document image files. The output of the system is an ontology that provides the conceptual framework for the domain. The ontology evolves as web pages with additional relevant data are harvested and processed. Constructing ontologies is currently a labor and skill intensive process. The TANGO framework automates much of the ontology construction task for a domain when information exists in lists and tables that describe the domain. The results of this project build stepping stones to the Semantic Web, for which ontologies are a central component. Therefore, this project will have an impact on users of the Semantic Web, who assisted by the automated software agents developed in this project, can accomplish information-based tasks for research, scholarship, planning, design, education, and entertainment. This cross-disciplinary and cross-university endeavor introduces graduate and undergraduate students to cutting-edge research. Developed tools (including source programs), a corpus of tables both in raw and normalized forms, collected test data, and technical reports can be found at the project website (http://www.tango.byu.edu).
