Abstract
Web 2.0 portals have made content generation easier than ever with
millions of users contributing news stories in form of posts in weblogs
or short textual snippets as in Twitter. Due to the increasing
popularity of these streams, people become overwhelmed by the available
information. In this talk we will discuss techniques on how to extract
the essence of available information to be reported to users. We
envision a system which continuously keeps users updated with only the
top-k relevant new information. We propose an efficient information
filtering technique to limit the number of necessary profiles
(continuous queries) which should be compared to an incoming document,
hence, ensuring scalability to large number of users. In addition, we
present a technique to monitor emergent topics over these Web 2.0
streams by continuously monitoring correlations between pairs of tags
(social annotations), identifying major shifts in correlations of
previously uncorrelated tags. We coined our approach "en Blogue" to
reflect the analogy with emerging trends in fashion often referred to as
"en Vogue".
