in the Virtual extension

To ensure the timely publication of articles, Communications created the Virtual Extension (VE) to expand the page limitations of the print edition by bringing readers the same high-quality articles in an online-only format. VE articles undergo the same rigorous review process as those in the print edition and are accepted for publication on merit. The following synopses are from articles now available in their entirety to ACM members via the Digital Library.

information seeking:
convergence of search,
Recommendations, and
advertising
Hector Garcia-Molina, Georgia Koutrika,
and Aditya Parameswaran
All of us are faced with a “deluge of data”
in our workplaces and our homes: an
ever-growing World Wide Web, digital
books and magazines, photographs,
blogs, tweets, email messages, databases,
activity logs, sensor streams, online videos,
movies and music, and so on. Thus, one
of the fundamental problems in computer
science has become even more critical
today: how to identify objects satisfying
a user’s information need. The goal is to
present to the user only information that is
of interest and relevance, at the right place
and time.
