Not without pride I see two of my papers being accepted at the upcoming conferences ACM Hypertext (HT) and ACM/IEEE Joint Conference on Digital Libraries (JCDL) . The paper " Evaluating Methods to Rediscover Missing Web Pages from the Web Infrastructure " will be published at JCDL. It is co-authored with my advisor Dr. Michael L. Nelson . As part of my ongoing dissertation work we are investigating methods to rediscover missing web pages with the help of the web infratructure (search engines, their caches, the Internet Archive, etc) in real time meaning while the user is browsing the web.

Well worth the listen even if you know a good deal about Memento. -- Michael
