The web provides a lot of fluid information but this information changes , moves , and even disappears over time . Bookmark lists , portals , and paths are collections where the building blocks are web pages , which are susceptible to these changes . A lot of research , both in industry and in academia , focuses on organizing this vast amount of data . In this thesis , I present context -based algorithms for measuring changes to a document . The methods proposed use other documents in a collection as the context for evaluating changes in the web pages . These metrics will be used in maintaining paths as the individual pages in paths change . This approach will enhance the evaluations of change made by the currently existing Path Manager , in the Walden's Paths project that is being developed in the Center for the Study of Digital Libraries at Texas A &M University . |
