ITR: Long-Lived Information Artifacts Based on Short-Lived Administratively-Decentralized Source Material

wide - world Web的庞大规模要求提供门户、热点列表和其他以面向域的方式组织Web内容的目录。但是，所包含的信息的质量会随着内容的变化、站点的重组和主机连接的波动而下降。简单地检测资源已经更改是很容易的，但是确定该更改是否重要需要了解使用该资源的上下文。这个项目将提高网页集合的稳定性，允许开发可预测的集合，从而克服万维网固有的不稳定性。为了实现这一目标，该项目将研究集合创建者提供的语义描述符和从集合中提取的隐式上下文信息的适用性。

The sheer size of the World-Wide Web mandates the provision of portals, hotlists, and other catalogs that organize Web content in a domain-oriented manner. However, the quality of the information contained is subject to degradation as content changes, sites reorganize, and host connectivity fluctuates. Simply detecting that a resource has changed is easy, but determining whether that change is significant requires understanding of the context in which the resource is used. This project will improve the stability of collections of Web pages, allowing the development of predictable collections that overcome the inherent instability of the World-Wide Web. To accomplish this goal, the project will investigate the applicability of semantic descriptors provided by collection creators and implicit contextual information extracted from the collection.
