Research Interests
My research interests fall in the intersection of information
integration, intelligent systems, and mobile multimedia focusing
on the broader business, social, and policy implications associated
with the emerging mobile and Web technologies.
Barely more than ten years after the birth of the
World Wide Web, the Global Information Infrastructure is a
daily reality.
In spite
of the many applications in all domains of our societies:
e-business, e-commerce, e-learning, e-science, and e-government,
for instance,
and in spite of the tremendous advances by engineers
and scientists, the seamless integration of information and
services remains
a major challenge. The current shared vision for the
future is one
of semantically-rich information and service oriented
architecture for global information systems. This vision is
at the convergence
of progress in technologies such as XML, Web services,
RDF, OWL, of multimedia, multimodal, and multilingual information
retrieval,
and of distributed, mobile and ubiquitous computing.
- Agents interactions in ubiquitious environments
Intelligent systems are systems that are characterized to
consist of intentional entities (agents)
who are self-aware (autonomous:
free to perceive, free to make
decision, free to act), who have goals, who can think about
how
to match up
to their own and other
agents standards, and who will
act in ways to influence other’s
view.
In this context, they 1.) are
created for some reason (purpose
and orienting
towards
it),
2.) have values
which determine
their behaviour and based on
these values agents’ actions
can be decided as good, right,
and even moral, 3.) have control
over
their actions (accept a task,
negotiate, or
reject) and this control is maximized
by reaching
challenging goals,
and 4.) have
positive values (self respect
and respect
of others)
Interaction is the act or process
where agents communicate in a
way to influence
the behaviour
or belief of
other agents. Agents’ interaction
takes the form of coordination,
cooperation, collaboration, negotiations,
contracts,
agreement, communication
protocols, and speech acts.
My focus is on Agents’ interaction
in ubiquitous environment which
is generally characterized
by 1) openness, describing
the possibilities that these
mobile entities can join or leave
the
environment, 2) flexibility indicating
the degree
the mobile entities are restricted
by the environment rules
and norms,
3) stability
defining the predictability of
the consequences of actions and
4) trustfulness
specifying
the extent to which users
may trust
the environment.
Social aspects of multi-agents systems have received
a lot of attention from the community since social
ability is one
of the
most important
attributes of agents which has opened up new modes
of interaction and dynamic organizational configurations
that were previously
inconceivable within a wide array of human and business
activities.
Most important is how agents interactions can be
modelled using norms which are interpreted in different
contexts and
understood
to mean a standard expectation about what behaviour,
thoughts, or feelings are appropriate within a given
group (of agents)
within a given context (i.e., location, time, environment)
and to show
how agents should behave based on established protocols,
rules of conduct or accepted social practices.
The field of mobile computing and multimedia is expanding
in an unprecedented pace. Indicators
are the rapidly increasing penetration
of the cellular phone market around the
world, and the mobile computing market is growing nearly
twice
as fast as
the desktop
market. In
addition, technological advancements
have significantly enhanced the usability of mobile communication
and computer
devices.
From the first CT1 cordless telephones
to today’s Iridium mobile
phones and laptops/PDAs with wireless Internet connection, mobile
tools and utilities have made the life of many people at work and
at home much easier and more comfortable. As a result, mobility
and wireless connectivity are expected to play a dominant role
in the future in all branches of economy. The addition of mobility
to data communications systems has not only the potential to put
the vision of “being always on” into
practice, but has also enabled new generation
of services, e.g.,
location-based services. My focus is
on topics leveraging all aspects of mobile
and multimedia computing: from underlying
technologies
to applications, theory to practice,
and
servers to networks to devices is precisely
the ability to deploy and utilize modern
technologies
for the design,
development and deployment of a content
rich, user and business friendly, integrated
network
of autonomous,
mobile
applications
and services.
