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.

万维网的巨大规模要求提供门户网站、活动列表和其他以面向领域的方式组织Web内容的目录。然而，随着内容的更改、站点的重组和主机连接的波动，所包含的信息的质量可能会下降。简单地检测资源是否已更改很容易，但要确定该更改是否显著，则需要了解资源的使用环境。该项目将提高网页集合的稳定性，使可预测的集合得以开发，以克服万维网固有的不稳定性。为了实现这一目标，该项目将调查集合创建者提供的语义描述符和从集合中提取的隐含上下文信息的适用性。
