Information Discovery and Communication with Meta-Documents over the World-Wide Web

这个项目研究了使用一个额外的结构层，称为元文档，来组织分散的网络可访问信息，比如在万维网上发现的信息。通过开发元文档（其组件本身就是文档的文档），可以将发现的信息放入上下文中并与他人交流。因此，元文档在需要传递由他人创建和维护的信息的应用程序中很有前途；各级教育应用都具有这一特点。为了使元文档有效，本项目探讨了信息表示、表示、个性化、结构、位置和探索方面的基本问题。此外，还需要对编写元文档的方法以及使它们与快速变化的Web内容保持同步的方法进行实际研究。由此产生的概念对理解如何构建和交流基于网络的数字信息具有理论意义。它们在制作可用于教学的材料和提供概述方面也有直接的实际应用，这些概述将帮助公众更好地识别有关选定主题的网络信息。http://www.csdl.tamu.edu/walden/

This project investigates use of an additional layer of structure, called a meta-document, to organize decentralized network-accessible information, such as that found on the World-Wide Web. By developing meta-documents, documents whose components are themselves documents, discovered information can be placed into context and communicated to others. Consequently meta-documents hold promise of being useful in applications where information, created and maintained by others, needs to be transferred; educational applications at all levels have this characteristic. To make meta-documents effective, basic issues in information representation, presentation, personalization, structuring, location, and exploration are explored in this project. In addition, practical study is required of the means for authoring meta-documents and the means for keeping them in synchrony with the rapidly shifting contents of the Web. The resulting concepts have theoretical implications in understanding how to structure and communicate network-based digital information. They also have immediate practical application in producing materials that can be used in teaching and in providing overviews that will help the general public better identify relevant Web-based information on selected topics.http://www.csdl.tamu.edu/walden/
