SECOND CALL FOR PAPERS

Appification of the Web (AppWeb2012)
Workshop at the 21st World Wide Web Conference (WWW 2012)
http://sites.google.com/site/appweb2012/
April 16, 2012 - Lyon, France

We solicit submissions for the Workshop on Appification of the Web, to
be held on April 16, 2012, in Lyon, France, in conjunction with the
21st World Wide Web Conference (WWW 2012). The workshop will bring
together researchers and practitioners from industry and academia to
discuss the impact of mobile apps on the Web search and browsing
paradigms.

Recent proliferation of smartphones and tablet devices is due at least
in part to the advent of apps, which customize and streamline user
experience in a variety of usage scenarios. Today, hundreds of
thousands of apps exist on the major mobile OS platforms (notably, iOS
and Android), and we are witnessing a clear change in the way people
consume and interact with information online. Beyond the mobile
devices, we are witnessing the increasing availability of OS-level
apps (in Mac OS, and forthcoming in Windows) as well as browser apps
(notably, in Google Chrome). In many cases, users' information needs
can be satisfied by an app or a combination thereof, completely
circumventing the heretofore predominant Web search and browsing
paradigms. For instance, instead of searching for travel options on
the Web, one can directly use one of the popular travel apps.
According to a recent survey, typical iPhone users have 108 apps
installed on their device, and spend on average 84 minutes a day using
them, thus confirming that changes in information consumption patterns
on the Web are already well under way.

The primary objective of the workshop is to understand and to quantify
the changes in Web usage due to the apps. The secondary objective is
to understand the forthcoming changes, e.g., whether the role of Web
search is likely to be fundamentally transformed, as apps satisfy an
increasing fraction of user's information needs.

Papers from a rich set of empirical, experimental, and theoretical
perspectives are invited. Topics of interest for the workshop include
but are not limited to:
- Do mobile apps provide a fundamentally better user experience?
- Understanding why and to what extent users tend to invoke apps
directly instead of using Web search and browsing. Will mobile apps
cause Web search in the future to be limited only to tail queries?
- Web search as an app recommendation system. Surfacing apps that are
relevant to user's search queries and are likely to help users
accomplish their goals faster. Satisfying user's action needs with
apps.
- New approaches to app indexing and search. More generally, the
design of app retrieval systems, which take into account the plurality
of information available about each app, including its textual
description as well as meta-information, such as reviews, ratings,
related queries, etc.
- Apps as a new frontier in Web monetization
- Do apps provide better user retention?
- Building richer user profiles based on app usage ("you are what you app")
- Chaining multiple apps to help users complete complex tasks
- Changes in mobile Web usage due to the availability of significant
local processing power, as opposed to solely centralized processing.
Ramifications of applications that use both local and cloud
computation, as exemplified by the Opera and recently released Amazon
Silk browsers.

The workshop will include invited talks as well as presentations of
accepted research contributions.

Registration will be open to all WWW 2012 attendees.
