Currently, I am working on the GiveALink project with Filippo Menczer and Ben Markines, fellow PhD student and Network and agents Network (NaN) member.
GiveALink is a social bookmarking site where people can donate their bookmarks to the Web community and to science. Our goal is to analyze bookmark files to build new Web mining techniques including new ways to search, recommend, personalize, and visualize the Web. What makes GiveALink different from many social bookmarking sites is that we do not ask users to tag the bookmarks, and that we use the hierarchical structure of folders, if such folders are present, to extend basic collaborative filtering techniques in estimating the similarity or relationship between two urls.
My particular interests lie in personalizing web browsing and discovery, helping users find new pages of interest from among the many sites out there through personalized search and recommendations, for example.
I also previously collaborated with Ana Maguitman, Fil Menczer, and Alessandro Vespignani on a way to automatically measure similarity between two urls classified in an ontology (such as the Open Directory Project) for use in automatically testing new similarity measures based on the content and/or link structure of the pages. This work led to a paper which was a finalist for the best paper award at WWW2005. (Alas, we did not win.)
