Abstract
This is a survey how cell-phones are interacting with a real world with I/O devices in information
retrieval. Many cell-phones are now being equipped with many I/O devices including
GPS, microphones, CCD/CMOS cameras, and motion-sensors. Thus content delivery, interaction
with contents, and e-commerce are going to be associated with real environments
which will bring us context-aware(real-world aware) capability. Here we see the clear distinction
between cell-phones and mobile laptop PCs in that context. Interaction is the key when
considering mobile information retrieval. Having 3G broadband and low-latency technologies,
“always-on” mobile infrastructure has brought an on-demand and real-time information
retrieval capability in conjunction with a popular communication culture, which we call “the
third generation of cell-phone culture”, which was never seen before. That is in next two
decades, billions of cell-phones are now being connected to server cloud. We may have a
different level of real-word aware computing which has not emerged yet.

Abstract
Web search engines today require users to specify their interests
using keywords. By and large, they are successful
because the web is so large and so diversify that any reasonable
keywords can return some useful documents, whether
or not the most relevant or most complete results are returned
is a different question. Information filtering aims at
matching dynamic information sources against a relatively
static user profile to pick up documents that are of interest
to the users. It has been studied in the information retrieval
community, albeit with less intensity compared to search.
In the mobile scenario, letting interesting information find you is often more important than finding the interesting information when it is needed. The proactive and context-aware nature of information push will manifest itself into all levels and all aspects of mobile information retrieval, turning the mobile device from a place where user commands are issued to a place where information is automatically collected for the user. This talk discusses user profiling methods for monitoring user actions to extract content-based and location-based user profiles, wireless data dissemination architectures that cater for ad hoc location-based information publishing, and applications on mobile advertisements.

Abstract
With the increasing popularity and usage of camera-equipped
mobile devices, large amounts of mobile media content (images
and videos) have been generated and are growing rapidly in
recent years. This has led to proliferation of mobile media
applications. A new trend in mobile media applications centered
on mobile media annotation and sharing has emerged and begun
to gain popularity and importance recently. This paper will
present an overview on mobile media annotation and sharing.
Issues and challenges encountered in current media annotation
and sharing systems will be discussed. The main characteristics of
media annotation and sharing in a mobile environment will be
outlined. Finally, future trends in mobile media annotation and
sharing will be presented.
