(RoSOC-M'09)

May 19, 2009

in conjunction with the 10th International Conference on Mobile Data Management
(MDM'09)

May 18-21, 2009, Taipei, Taiwan

THEME OF THE WORKSHOP

The theme of the workshop is the intersection of three major trends in today?s
computing:

* mobile computing becomes more and more important. Mobile portable
devices have outnumbered already traditional desktop computers and
will mould the view of computers future generations will have.
* service-oriented computing is viewed by many analysts as the computing
paradigm of the near future. It allows for the dynamic integration of
functionality provided by different parties.
* research on ontologies, in particular in connection with work on the
semantic web and semantic web services allows for machine understandable
description of functionality and for automatic interaction of devices without
the need for human involvement.

The proposed workshop investigates how mobile computing can benefit from
service-orientation and ontologies and vice versa. The vision is to extend the
typically rather limited capabilities of mobile devices by using services offered
by other devices, network providers or third parties. Adding ontologies to this
scenario allows this extension to be transparent to the human user. Further,
some high-end mobile telecom terminals can be called already multimedia
computers due their programmability,processor speed, and gigabytes of memory.
Already in the near future these devices could also utilize ontologies locally during
service provisioning.


GENERAL OVERVIEW

Today, computers are changing from big, grey, and noisy things on our desks to
small, portable, and ever-networked devices most of us are carrying around.
This new form of mobility imposes a shift in how we view computers and the way
we work with them.

Services offer the possibility to overcome the limitations of individual mobile
devices by making functionality offered by others available to them on an
?as-needed? basis. Thus, using the service-oriented computing paradigm in
mobile environments will considerably enlarge the variety of accessible
applications and will enable new business opportunities in the mobile space by
delivering integrated functionalities across wireless networks. Network hosted
mobile services will allow mobile operators and third party mobile services
provider to extend their businesses by making their network services available
to a broader audience (e.g. developers, service providers, etc.); device hosted
service will allow great potential for big innovations for applications and
services that can be provided by individual mobile device owners.

These mobile service-oriented systems offer functionalities and behaviors that
can be described, advertised, discovered, and composed by others. Eventually,
they will be able to interoperate even though they have not been designed to
work together. This type of interoperability is based on the ability to
understand other services and reason about their functionalities and behaviors
when necessary. In this respect, mobile service-oriented systems can benefit
from marrying the Semantic Web, which provides the infrastructure for the
extensive usage of distributed knowledge, to be deployed for modeling services
and add meaning, through ontologies, enabling lightweight discovery and
composition of mobile services. The ability to appropriately combine mobility
and semantic grounded data sharing has generated and is continuously triggering
challenging questions in several areas of computer science, engineering and
networking.

A third dimension is added when taking context information into account: Now,
we are no longer dealing with the information system any more, but the real
world is intermingled with the computing and will immediately affect and
interact with the processing of data and communication. Real-world context
information can help to more efficiently exploit the limited resources in
mobile environments by supporting better ways to provide data relevant to the
user, to enable improved interoperability with the environment and with other
mobile users, and to decide when and how to process data.

So far, the contextual and semantic aspects of mobile environments have
received insufficient attention from the research community as the specific
intricacies and resource issues of mobile environments have not been considered
and in mobile data management only limited attention has been paid to context
and semantics. In this workshop we plan to address the interdisciplinary issues
of the domain and bring together researchers and industry attendees from mobile
data management, knowledge management/semantics, distributed systems,
service-oriented computing, and software engineering to discuss the common
interests, share and exchange expertise and results, appreciate each other's
results and contributions. The long-term goal is to provide application
developers with facilities (middleware, infrastructures, agent systems, service
platforms, etc.) that enable the development and deployment of context-aware
applications in mobile and pervasive environments.

The RoSOC-M '09 workshop is a follow-up edition of the RoSOC-M '08 workshop,
which in turn was a joint event of the previous MoSO and MCISME workshop
series: MoSO'07, MCISME'07, MoSO'06, MCISME'06.
