Word-Wide Correlated Activities
Semantic Web
Agentcities is a global, collaborative effort to
construct an open network of on-line systems
hosting diverse agent based services.
Semantic Web is an extension of the current web
in which information is given well-defined meaning
, better enabling computers and people to work
in cooperation
Agentcities
Grid Computing
Wide-area distributed computing, or "grid
technologies, provide the foundation to a number
of large-scale efforts utilizing the global
Internet to build distributed computing and
communications infrastructures.
FIPA
FIPA is a non-profit organisation aimed at
producing standards for the interoperation of
heterogeneous software agents.
Web Services
WWW is more and more used for application to
application communication. The programmatic
interfaces made available are referred to as Web
services. The goal of the Web Services Activity
is to develop a set of technologies in order to
bring Web services to their full potential

DAI Course Exercise
26
Task for the Exercise (according to A. Raja) (1)
  • Consider the home of the future where there
    are software agents in a mobile environment that
    are helping to manage the running of a house.
    There will be
  • (1) Personal assistant agents that will know of
    your preferences of temperature, humidity, light,
    sound, etc., and who you want to interact with
  • (2) There will be agents that can measure
    appropriate environmental conditions with
    specific devices
  • (3) There will be agents that effect appropriate
    environmental conditions with specific devices
  • (4) There will be agents that control expenses
    for the use of appropriate devices
  • (5) There will be agents that manage the
    telephone communications
  • (6) There will be agents that manage security
    issues such as fire, earthquake, flood
    protection, etc.

27
Task for the Exercise (according to A. Raja) (2)
  • Assume that the agents are heterogenous (i.e.
    have not be generated by one designer), for
    example when you get a new device it will come
    with an agent for instance, the heating
    measurement agent may not come from the same
    company as the air-conditioning agent.
  • Think about the possibility of having these
    agents work together. What are the capabilities
    of the agents, what type of cooperation needs to
    occur among them, are there needs for the agents
    to negotiate, are there situations where local
    objectives are at odds with global objectives
    such as minimizing electrical usage? What type of
    information needs to be exchanged among the
    agents?

28
Task for the Exercise (according to A. Raja) (3)
  • How would you organize the agents would you
    have a hierarchy of agents in terms of their
    control responsibilities? How would you allow
    agents to integrate new agents into the system,
    for instance, when you buy a new device.
  • What are the specific characteristics required by
    a language in order that these agents can share
    information? If there are no dedicated resources
    for each agent, but rather a pool of resources
    that can be used by agents, what new issues does
    this introduce? Do agents need to reason about
    the intentions of other agents?

29
Task for the Exercise (according to A. Raja) (4)
  • In answering these and related issues that you
    may consider, please be concrete with specific
    and numerous examples/scenarios. You should first
    start out the effort by detailing the collection
    of agents that you see in the house of the
    future, what their responsibilities are, and
    their patterns of interaction with other agents.
    Including figures, it should be at least 3 to 5
    pages long.

DAI Course Assignment
32
Assignment in brief
  • Students are expected to select one of below
    recommended papers, which is not already selected
    by some other student, register his/her choice
    from the Course Lecturer and make PowerPoint
    presentation based on that paper. The
    presentation should provide evidence that a
    student has got the main ideas of the paper, is
    able to provide his personal additional
    conclusions and critics to the approaches used.

Semantic Metanetwork for Metadata Management
Semantic Metanetwork is considered formally as
the set of semantic networks, which are put on
each other in such a way that links of every
previous semantic network are in the same time
nodes of the next network. In a Semantic
Metanetwork every higher level controls semantic
structure of the lower level.

Multilevel Contexts in Semantic Metanetworks, In

Publishers, 2000, pp. 107-126.

Petri Metanetwork for Management Dynamics
  • A metapetrinet is able not only to change the
    marking of a petrinet but also to reconfigure
    dynamically its structure
  • Each level of the new structure is an ordinary
    petrinet of some traditional type.
  • A basic level petrinet simulates the process of
    some application.
  • The second level, i.e. the metapetrinet, is used
    to simulate and help controlling the
    configuration change at the basic level.
